Description

[Technical Field]

[0001] The present invention relates to a composition containing at least one polypeptide capable of binding to fungi, and to the at least one polypeptide itself. The present invention also relates to the use of the composition as an antifungal agent. The present invention further relates to a method for protecting or treating a plant or a part of the plant from infection by plant pathogenic fungi, a post-harvest treatment method for protecting or treating a harvested plant or a harvested part of the plant from infection by plant pathogenic fungi, and a method for inhibiting the growth of plant pathogenic fungi or killing plant pathogenic fungi, comprising at least the step of applying the composition or the polypeptide directly or indirectly to a plant or a part of the plant. The present invention also relates to a method for producing an antifungal polypeptide and a method for producing an antifungal composition. Furthermore, the present invention also relates to transgenic plants, plant parts, seeds, or plant cells. [Background technology]

[0002] The presence and persistence of pathogenic fungal infections, observed not only in patients and animals but also in cultivated plants, is likely due primarily to the selective pressure on broad-spectrum antifungal agents and the generally insufficient effectiveness of currently available antifungal drugs.

[0003] In humans and animals, systemic fungal infections such as invasive candidiasis and invasive aspergillosis are thought to be caused by various fungal pathogens. Examples include the highly virulent Candida species Candida albicans, Candida tropicalis, and Candida krusei, and the less virulent species Candida parapsilosis and Torulopsis glabrata (also known as Candida glabrata). Previously, Candida albicans was the most common fungal isolate obtained from intensive care units, but subsequent reports indicate that Candida tropicalis, Candida glabrata, Candida parapsilosis, and Candida krusei now account for about half of such isolates. The rise of non-albicans Candida species signifies the emergence of Candida species resistant to conventional antifungal drugs.

[0004] Traditionally, Candida albicans, Candida tropicalis, and Candida parapsis were treated with amphotericin B, an antifungal drug considered the "gold standard" of systemic antifungal therapy. Unfortunately, amphotericin B is highly toxic, and its use is limited by side effects including chills, fever, muscle pain, or thrombophlebitis. Other antifungal drugs include oral azoles (miconazole, ketoconazole, itraconazole, fluconazole) and 5-fluorocytosine. However, some fungal species, such as Candida crusay and Torulopsis glabrata, are resistant to fluconazole, and these species often occur in patients who have received prophylactic treatment with this drug. Furthermore, fluconazole-resistant strains of Candida albicans have also been reported. Therefore, despite advances in antifungal drugs, the need for effective treatments for fungal infections remains an urgent issue.

[0005] In agriculture, crop protection heavily relies on the use of pest control agents applied to crops by spraying, irrigating, or injecting into the soil. Pest control agents are often organic chemical molecules, and repeated application to crops poses a toxic threat to both agricultural workers and the environment through drift, soil persistence, or runoff into the surface or groundwater. It would be advantageous to use alternative compounds that offer effective control of plant pests while having low toxicity to humans and the environment. Protein pest control agents with specificity to particular plant pest targets appear highly advantageous in this regard, as they are expected to have short environmental presence and low-toxicity off-target effects. However, only a small number of protein or peptide pest control agents are known. Examples include Bt toxin, lectins, defensins, favatin, tachypressin, magainin, harpin (see WO2010019442), and pea mealbumin 1 subunit b (PA1b). However, these protein pest control agents are either small molecular weight peptides with a compact structure stabilized by a few disulfide bonds, or large proteins (>300 amino acids) that exist in crystalline form (cry toxins). In fact, biological agents, especially proteins, are generally known in the agricultural field to have extremely low stability and cannot maintain their pest control function, particularly in field pesticide formulations, making their structure difficult to use in pest control agents.

[0006] [Patent Document 1] International Publication No. 2010 / 019442 [Overview of the project] [Problems that the invention aims to solve]

[0007] The inventors have succeeded in developing a polypeptide that exhibits remarkably high specificity, affinity, and efficacy against harmful organisms, particularly, but not limited to, plants, animals, or human pathogenic fungi. The polypeptide can bind to specific lipid fractions of the cell membrane of fungal spores. The binding of the polypeptide alone is sufficient to prevent mycelial formation by delaying spore growth and / or causing lysis and rupture, thereby exhibiting mycogenic activity. Therefore, the polypeptide can have either mycogenic or mycstatic activity.

[0008] Furthermore, these polypeptides can maintain their integrity, stability, and activity within the composition, and remarkably, effective control of pests or pathogens can be achieved by applying compositions containing the polypeptides disclosed herein to crops, animals, or humans.

[0009] The efficacy and efficacy of the polypeptides disclosed herein suggest that dose reduction may be possible and / or that more effective treatment may be possible at the same dose. This is expected to lead to a reduction in undesirable side effects and toxicity in both agrochemical and pharmaceutical applications. Furthermore, it may be possible to apply the polypeptides or compositions disclosed herein in smaller amounts or dosages.

[0010] More specifically, the inventors have found that by targeting and delivering the polypeptide envisioned in this application to the molecular structure of a harmful organism or pathogen, the pathogen can be efficiently controlled.

[0066] Detailed description of the invention When prior art is mentioned in this specification, it should not be considered, nor should it be considered, as an indication that such prior art constitutes common knowledge in any country.

[0067] All references herein are incorporated herein by reference in their entirety. Unless otherwise defined, all terms used to disclose the present invention, including scientific and technical terms, are to be understood as they are to a person of ordinary skill in the art to which the present invention pertains.

[0068] The present invention is described below in terms of specific embodiments, but the present invention is not limited to these embodiments and is limited only to the claims. When reference numerals are included in the claims, they should not be construed as limiting the scope of the claims.

[0069] definition When the term “including” is used in this specification and in the claims, it does not exclude any other elements or processes.

[0070] When referring to a singular noun, for example, using an indefinite or definite article such as "a," "an," or "the," unless otherwise specified, it includes the plural form of that noun.

[0071] When referring to measurable values ​​such as parameters, quantities, and times, the term "approximately" as used in this application means that the variation includes ±10% or less of the specified value, preferably ±5% or less, more preferably ±1% or less, and even more preferably ±0.1% or less, provided that such variation is appropriate in the invention disclosed herein. Naturally, the numerical values ​​themselves that are "approximately" included are also disclosed as specifically preferred numerical values.

[0072] The following terms and definitions are provided solely to aid in understanding the present invention. Unless otherwise defined herein, all terms used herein have the same meaning as those used by those skilled in the art. With regard to definitions and terms in the art, the practitioner particularly refers to Sambrook et al., Molecular Cloning: A Laboratory Manual, 2 ndSee ed., Cold Spring Harbor Press, Plainsview, New York (1989); and Ausubel et al., Current Protocols in Molecular Biology (Supplement 47), John Wiley & Sons, New York (1999). The definitions used herein should not be construed as being narrower than what would be understood by a person of ordinary skill in the art.

[0073] Unless otherwise specified, all methods, processes, techniques, and operations not described in detail can and have been carried out in methods known to those skilled in the art, and are self-evident to those skilled in the art. For further information, please refer to, for example, the standard handbook, the general background art described above, and other references cited herein.

[0074] As used in this application, the terms “polypeptide,” “protein,” “peptide,” and “amino acid sequence” are used synonymously and refer to polymer-type amino acids of any length. These can include coded amino acids, non-coding amino acids, chemically or biochemically modified or derivatized amino acids, and polypeptides having a modified peptide backbone.

[0075] The amino acid residues used in this application may be represented by their full letter notation, or they may be represented according to the standard three-letter or one-letter amino acid code.

[0076] As used in this application, the terms “nucleic acid sequence,” “polynucleotide,” “polynucleic acid,” and “nucleic acid” are used synonymously and refer to nucleotides of any length in polymer form that are deoxyribonucleotides or ribonucleotides or analogs thereof. Polynucleotides can have any three-dimensional structure and can perform any known or unknown function. Non-limiting examples of polynucleotides include genes, gene fragments, exons, introns, messenger RNA (mRNA), transfer RNA, ribosomal RNA, ribozymes, cDNA, recombinant polynucleotides, branched polynucleotides, plasmids, vectors, isolated DNA of any sequence, regulatory regions, isolated RNA of any sequence, nucleic acid probes, and primers. The nucleic acid molecules may be linear or cyclic.

[0077] As used in this application, the term “homology” means at least secondary structural similarity between two polymers, particularly two polypeptides or polynucleotides, derived from the same or different taxones, where such similarity stems from a common ancestor. Therefore, the term “homology” means polymers of such a relationship having the aforementioned secondary structural similarity and optionally tertiary structural similarity. To compare two or more nucleotide sequences, the “percentage of sequence identity” between a first and second nucleotide sequence can be calculated using methods known to those skilled in the art, such as dividing the number of identical nucleotides in the first nucleotide sequence to the nucleotide at the corresponding position in the second nucleotide sequence by the total number of nucleotides in the first nucleotide sequence and multiplying by 100%, or using known computer algorithms for sequence alignment such as NCBI Blast. When determining sequence identity between two amino acid sequences, those skilled in the art may consider so-called “conservative” amino acid substitutions, which can generally be described as amino acid substitutions that, when an amino acid residue is replaced with another amino acid residue of similar chemical structure, have little or no effect on the function, activity, or other biological properties of the polypeptide. Possible conserved amino acid substitutions are obvious to those skilled in the art. Amino acid sequences and nucleic acid sequences are said to be "strictly identical" if they have 100% sequence identity over their entire length.

[0078] As used herein in the context of antibodies, the term "complementary determining region" or "CDR" means the variable region of either the H (heavy) chain or the L (light) chain (abbreviated as VH and VL, respectively), and includes an amino acid sequence capable of specifically binding to an antigen target. These CDR regions determine the base specificity of the antibody for a particular antigen determinant structure. Such regions are also referred to as "hypervariable regions". CDRs correspond to discontinuous amino acid stretches within the variable region, and regardless of the molecular species, the positions of these important amino acid sequences within the heavy-chain variable region and the light-chain variable region have been found to have similar positions within the amino acid sequence of the variable region chain. The heavy-chain and light-chain variable regions of all standard antibodies each have three CDR regions (referred to as L1, L2, L3, H1, H2, H3, respectively) that are discontinuous with each other in their respective light (L) and heavy (H) chains.

[0079] As used herein, the term "affinity" means the degree to which a polypeptide, particularly an immunoglobulin such as an antibody or an immunoglobulin fragment such as VHH, binds to an antigen so as to shift the equilibrium of the antigen and the polypeptide towards the side of the existence of the complex formed by their binding. Thus, for example, when an antigen and an antibody (fragment) are combined at relatively equal concentrations, a high-affinity antibody (fragment) will bind to the available antigen so as to shift the equilibrium towards the high-concentration side of the resulting complex. The dissociation constant is widely used to represent the affinity between a protein-binding domain and an antigen target. Generally, the dissociation constant is less than 10 -5 M. The dissociation constant is preferably less than 10 -6 M, more preferably less than 10 -7 M. Most preferably, the dissociation constant is less than 10 -8 M.

[0080] As used in this application, the terms "specifically bind" and "specific binding" generally refer to the ability of a polypeptide, in particular an immunoglobulin such as an antibody or an immunoglobulin fragment such as VHH, to preferentially bind to a specific antigen present in a homogeneous mixture of various antigens. In certain embodiments, the specific binding interaction will distinguish between desirable and undesirable antigens in a sample, and in certain embodiments, the distinction will be by a difference of about 10 to over 100 times or more (e.g., about 1,000 times or over 10,000 times).

[0081] Accordingly, the amino acid sequences disclosed herein are said to "specifically bind" to a target if the amino acid sequences have affinity for, specific to, and / or specific association with a particular target (or at least one part or fragment thereof).

[0082] The "specificity" of the amino acid sequences disclosed herein can be determined based on affinity and / or avidity.

[0083] The amino acid sequences disclosed herein are said to be "specific to the first target antigen compared to the second target antigen" when they bind to the first target antigen with an affinity at least five times, for example, at least ten times, for example, at least 100 times, preferably at least 1000 times, the affinity with which the amino acid sequences bind to the second target antigen. Therefore, in a given embodiment, when the amino acid sequences disclosed herein are said to be "specific to" the first target antigen compared to the second target antigen, the amino acid sequences can bind specifically to the first target antigen (as defined herein) but cannot bind to the second target antigen.

[0084] As used in this Application, the terms “inhibit,” “suppress,” and / or “interfere” mean the use of any amino acid sequence disclosed herein that specifically binds to the target antigen and inhibits, suppresses, and / or interferes with the interaction between the target antigen and its natural binding partner. The terms “inhibit,” “suppress,” and / or “interfere” may also mean the use of any amino acid sequence disclosed herein that specifically binds to the target antigen and inhibits, suppresses, and / or interferes with the biological activity of the target antigen when measured using an appropriate in vitro assay, cell assay, or in vivo assay. Therefore, “inhibit,” “suppress,” and / or “interfere” may also mean the use of any amino acid sequence disclosed herein that specifically binds to the target antigen and inhibits, suppresses, and / or interferes with one or more biological or physiological mechanisms, actions, responses, functions, pathways, or activities in which the target antigen is involved. Such antagonistic activity of the amino acid sequences disclosed herein can be measured, depending on the target antigen, using any suitable method and / or any suitable (in vitro, typically cellular, or in vivo) assay known in the art.

[0085] Therefore, more specifically, "inhibiting," "suppressing," and / or "interfering" with the amino acid sequences disclosed herein can mean inhibiting, suppressing, and / or interfering with the interaction of the target antigen and its natural binding partner, or inhibiting, suppressing, and / or interfering with the activity of the target antigen, or inhibiting, suppressing, and / or interfering with one or more biological or physiological mechanisms, actions, responses, functions, pathways, or activities involving the target antigen by, for example, at least 10%, preferably at least 20%, for example, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, or at least 95% or more, compared to the activity of the target antigen measured using the same assay under the same conditions except that the amino acid sequences disclosed herein are not used. Furthermore, “inhibit,” “suppress,” and / or “interfere” may also mean inducing a decrease in the affinity, avidity, specificity, and / or selectivity of the target antigen to one or more of its natural binding partners, and / or inducing a decrease in the sensitivity of the target antigen to one or more conditions (e.g., pH, ionic strength, presence of cofactors, etc.) in the medium or environment in which the target antigen is present. In the context of the present invention, “inhibit,” “suppress,” and / or “interfere” may also mean allosteric inhibition, suppression, and / or interference of the activity of the target antigen.

[0086] The inhibitory or antagonistic activity, or the enhanced or activating activity, of the amino acid sequences disclosed herein may be reversible or irreversible, but in agricultural, pharmaceutical, and pharmacological applications, it will generally occur reversibly.

[0087] The amino acid sequences disclosed herein are considered "essentially isolated" as used herein when they have been extracted or purified from the host cells and / or culture media from which the amino acid sequences are produced.

[0088] With respect to the amino acid sequences disclosed in this application, the terms “binding region,” “binding site,” or “interaction site” present on the amino acid sequences disclosed in this application mean a specific site, region, locus, part, or domain present on the target molecule, and such specific site, region, locus, part, or domain is involved in binding to the target molecule. Accordingly, such a binding region is essentially composed of the specific site, region, locus, part, or domain of the target molecule that is in contact with the amino acid sequence when bound to the target molecule.

[0089] As used in this application, "plant" means the whole plant or a part thereof, including fresh fruit trees, vegetables, and seeds. The plant or plant part may be a living plant or a part thereof. Furthermore, as used in this application, the term "plant" also includes the whole plant, the ancestors and descendants of the plant and plant part, and includes seeds, shoots, stems, leaves, roots (including tubers), flowers, and tissues and organs, each of which contains the relevant genes / nucleic acids. The term "plant" also includes plant cells, suspensions, callus tissue, embryos, meristematic regions, gametophytes, sporophytes, pollen, and microspores, each of which also contains the relevant genes / nucleic acids.

[0090] The selection of an appropriate control plant is a routine part of experimental design and may include the corresponding wild-type plant or a corresponding plant that does not contain the gene in question. Generally, the control plant is the same species or variety as the plant to be evaluated. The control plant may also be a null zygote of the plant to be evaluated. A null zygote is an individual that loses the transgene upon isolation. As used in this application, "control plant" means not only the entire plant but also the plant part including the seeds and seed portion.

[0091] As used in this application, “crops” means plant species or varieties harvested for food, animal feed, fuel, or any other economic purpose. A non-limiting example of such crops includes: cereals such as maize, wheat, rye, barley, and oats, sorghum, rice, sugar beets, and fodder beets; pome fruits (e.g., apples and pears); citrus fruits (e.g., oranges, lemons, limes, grapefruit, or mandarin oranges); drupes (e.g., peaches, nectarines, or plums); nuts (e.g., almonds and walnuts); soft fruits (e.g., cherries, strawberries, blackberries, or raspberries); fruit trees such as Plantaginaceae or grapes; legumes, leguminous crops such as lentils, peas, and soybeans; and oils such as sunflowers, safflower, rapeseed, canola, castor, or olives.

[0118] As used in this application, the term "antibody" means polyclonal antibodies, monoclonal antibodies, humanized antibodies, single-chain antibodies and their fragments (e.g., Fab, F(ab)2, Fv, and other fragments that maintain the antigen-binding function of the parent antibody). Therefore, an antibody may also mean an immunoglobulin or glycoprotein or a fragment or portion thereof, or a construct containing an antigen-binding portion contained within a modified immunoglobulin-like framework, or an antigen-binding portion contained within a construct containing a non-immunoglobulin-like framework or scaffold.

[0119] As used in this application, the term "monoclonal antibody" refers to an antibody composition having a homogeneous antibody population. This term is not limited in terms of antibody species or origin, nor is it limited by the method of its preparation. This term includes full-length immunoglobulins and fragments such as Fab, F(ab)2, Fv, and other fragments that maintain the antigen-binding function of the antibody. In this invention, monoclonal antibodies from any mammalian species can be used. However, in practice, since rat or mouse cell lines are readily available for producing the hybrid cell lines or hybridomas necessary to produce monoclonal antibodies, the antibodies will generally be derived from rats or mice.

[0120] As used in this application, the term "polyclonal antibody" refers to an antibody composition having a heterogeneous population of antibodies. Polyclonal antibodies are often derived from a serum pool from immunized animals or selected humans.

[0121] As used in this application, "the heavy chain variable domain of an antibody or its functional fragment" refers to (i) the heavy chain variable domain of a heavy chain antibody that does not naturally have a light chain (hereinafter, V HH (ii) means, and is not limited to, the variable domain of the heavy chain of a camel or shark heavy chain antibody, or (ii) the variable domain of the heavy chain of a conventional quadruple-chain antibody (hereinafter, V H It also means, and is not limited to, the camel-modified variable domain (hereinafter referred to as camel-modified V) of the heavy chain of conventional quadruple-chain antibodies (as defined in detail in this application). H(Also known as)

[0122] As detailed below, the amino acid sequence and structure of the antibody's heavy chain variable domain can be considered, but are not limited, to consist of four framework regions or "FRs" referred to in the art and below as "framework region 1" or "FR1", "framework region 2" or "FR2", "framework region 3" or "FR3", and "framework region 4" or "FR4", respectively, and three complementarity-determining regions or "CDRs" positioned between the framework regions and referred to in the art as "complementarity-determining region 1" or "CDR1", "complementarity-determining region 2" or "CDR2", and "complementarity-determining region 3" or "CDR3", respectively.

[0123] Similarly, as detailed below, (V HH or V H The total number of amino acid residues in the heavy chain variable domain of an antibody (including) can be in the range of 110 to 130, preferably 112 to 115, and most preferably 113. Furthermore, the length and / or size of a portion, fragment, or analog of the heavy chain variable domain of an antibody is not limited, as long as such portion, fragment, or analog maintains (at least a part of) functional activity such as (as defined in this application) pesticide activity, biocidal activity, biostatic activity, fungicidal activity, or fungiostatic activity, and / or maintains (at least a part of) the binding specificity of the original heavy chain variable domain of the antibody from which these portion, fragment, or analog originates. In this application, a portion, fragment, or analog that maintains (at least a part of) functional activity such as (as defined in this application) pesticide activity, biocidal activity, biostatic activity, fungicidal activity, or fungiostatic activity, and / or maintains (at least a part of) the binding specificity of the original heavy chain variable domain of the antibody from which these portion, fragment, or analog originate is also referred to as a "functional fragment" of the heavy chain variable domain.

[0124] The method for numbering amino acid residues in the heavy chain variable domain is the method described by Chothia et al. (Nature 342, 877-883 (1989)), the so-called "AbM definition" and the so-called "contact definition." In this application, this is adopted as the numbering system.

[0125] Or, (V HH or V H The amino acid residues of the variable domain of the heavy chain variable domain of the antibody (including) are derived from camel V, as described in the aforementioned paper by Riechmann and Muyldermans (see, for example, Figure 2 in the above references). HH As applied to domains, they can be numbered according to the general numbering of heavy chain variable domains described by Kabat et al. ("Sequence of proteins of immunological interest", US Public Health Services, NIH Bethesda, Md., Publication No. 91).

[0127] In general, it should be noted that the term "heavy chain variable domain" as used in the broadest sense in this application is not limited to a specific biological origin or a specific method of production. For example, as detailed below, the heavy chain variable domain of the present invention is (1) V of a natural heavy chain antibody HH (2) Isolate the domain; (3) V of the natural quadruple-chain antibody H (3) Isolate the domain; (3) Natural V HH Express the nucleotide sequence that codes for the domain; (4) Natural V H (5) Express a nucleotide sequence that codes for the domain; (6) Natural V derived from any animal species, especially mammalian species such as humans.

[0129] As used in this application, the terms "effective amount" and "effective dose" refer to the amount necessary to achieve one or more desired results.

[0130] The terms "measure," "actually measure," "evaluate," "monitor," and "assay" used in this application are used synonymously and include both quantitative and qualitative measurements.

[0131] All references herein are incorporated herein by reference in their entirety.

[0132] polypeptide The polypeptides disclosed herein are generally capable of binding to fungi. Therefore, the polypeptides cause delays in the growth of the fungal spores and / or lysis of the fungal spores. That is, the binding of the polypeptides to fungi results in delays in the growth of the fungal spores and / or lysis of the fungal spores.

[0133] The polypeptides of the present invention and the polypeptides used in the present invention can (specifically) bind to fungal membranes or components of fungal membranes. In certain embodiments, the polypeptides of the present invention and the polypeptides used in the present invention do not (specifically) bind to fungal cell walls or components of cell walls. For example, in certain embodiments, the polypeptides of the present invention and the polypeptides used in the present invention do not (specifically) bind to fungal glucosylceramide.

[0134] The polypeptide can (specifically) bind to a lipid-containing fraction of a fungal cell membrane, such as a lipid-containing fraction of Fusarium oxysporum or another fungus. The lipid-containing fraction (of Botrytis cinerea or another fungus) may be obtained by chromatography. The chromatography can be performed on a crude lipid extract (also referred to here as a total lipid extract or TLE) obtained from fungal hyphae and / or conidia. The chromatography can be, for example, thin-layer chromatography or normal-phase flash chromatography. The chromatography (e.g., thin-layer chromatography) can be performed on a substrate, for example, on glass coated with silica gel. The chromatography can be performed using a chloroform / methanol mixture (e.g., 85 / 15% v / v) as the eluent.

[0135] For example, the lipid-containing fraction may be obtained by a method comprising the steps of fractionating the hyphae and / or conidia of a fungus (e.g., Botrytis cinerea or other fungi) by total lipid extract thin-layer chromatography, and selecting a fraction whose retention factor (Rf) is greater than that of the ceramide fraction and smaller than that of the nonpolar phospholipid fraction.

[0136] In a more specific embodiment, the lipid-containing fraction may be obtained by a method comprising the steps of fractionating fungal hyphae and / or conidia of a fungus (e.g., Botrytis cinerea or other fungi) by total lipid extract thin-layer chromatography using a chloroform / methanol mixture (e.g., 85 / 15% v / v) as the eluent on a silica-coated glass slide, and selecting a fraction having a retention factor (Rf) greater than that of the ceramide fraction and less than that of the nonpolar phospholipid fraction.

[0137] Alternatively, the fraction can be obtained using normal-phase flash chromatography. In such a method, the method may include the steps of fractionating the hyphae and / or conidia of a fungus (e.g., Botrytis cinerea or other fungi) by total lipid extract normal-phase flash chromatography, and selecting a fraction having a retention factor (Rf) greater than that of the ceramide fraction and less than that of the nonpolar phospholipid fraction.

[0138] In a more specific embodiment, the lipid-containing fraction may be obtained by a method comprising the steps of dissolving TLE in dichloromethane (CH2Cl2) and MeOH, fractionating the hyphae and / or conidia of a fungus (e.g., Botrytis cinerea or other fungi) by total lipid extract normal-phase flash chromatography using CH2Cl2 / MeOH (e.g., 85 / 15%, v / v) as the eluent, and then filtering the fraction through a filter.

[0139] In a more specific embodiment, the lipid-containing fraction may be obtained by a method comprising the steps of: dissolving the TLE in dichloromethane (CH2Cl2) and MeOH; loading the TLE into a normal-phase flash cartridge (e.g., a flash cartridge packed with 15 μm particles); and fractionating the hyphae and / or conidia of a fungus (e.g., Botrytis cinerea or other fungi) by total lipid extract normal-phase flash chromatography, wherein CH2Cl2 / MeOH (85 / 15%, v / v) is delivered to the column as the eluent; filtering the fraction through a filter (e.g., a 0.45 μm syringe filter fitted with a nylon membrane); and drying the fraction.

[0140] The fraction from the chromatography can be processed before testing the binding of the polypeptide to the fraction or the interaction between the polypeptide and the fraction. For example, liposomes containing the fraction can be prepared. Such a method may include thin-film hydration. For example, in such a method, liposomes can be prepared using thin-film hydration with the addition of 1,6-diphenyl-1,3,5-hexatriene (DPH). The binding and / or disruption of the membrane due to polypeptide binding can be measured by the change in fluorescence before and after polypeptide binding (or by referring to an appropriate control).

[0141] Accordingly, in certain embodiments, the polypeptides of the present invention and the polypeptides used in the present invention can (specifically) bind to the lipid-containing chromatographic fraction of a fungal cell membrane, and optionally, the lipid-containing chromatographic fraction is prepared into liposomes before testing the binding of the polypeptides.

[0142] The binding of the polypeptide to the lipid-containing fraction of the fungus can be confirmed by any suitable method, such as biolayer interference. Specific interactions with the lipid-containing fraction can be tested. For example, when preparing the fraction into liposomes using a thin-film hydration method, it can be confirmed whether the polypeptide can disrupt the lipid fraction.

[0143] In methods utilizing chromatography, an extraction step can be performed before the chromatography step. For example, fungal hyphae and / or conidia can be subjected to the extraction step to obtain a crude lipid extract or a total lipid extract, and chromatography can be performed on this extract. For example, in certain embodiments, fungal hyphae and / or conidia (e.g., hyphae and / or conidia of Fusarium oxysporum or Botrytis cinerea) can be extracted at room temperature using, for example, 2:1 and 1:2 (v / v) ratio chloroform:methanol. The extracts thus prepared can be combined and dried to obtain a crude lipid extract or TLE.

[0144] Accordingly, in certain embodiments, the polypeptide can (specifically) bind to a lipid-containing fraction of the cell membrane of a fungus (e.g., Fusarium oxysporum or Botrytis cinerea), and the lipid-containing fraction of the fungal cell membrane can be obtained or obtained by chromatography. The chromatography can be normal-phase flash chromatography or thin-layer chromatography. The binding of the polypeptide to the lipid-containing fraction can be measured by biolayer interferometry. In certain embodiments, the chromatography step can be carried out with a crude lipid fraction obtained or obtainable by a method that includes extracting lipids from fungal hyphae and / or conidia derived from a fungal sample. The extraction step can be performed to obtain two extracts using chloroform:methanol in 2:1 and 1:2 (v / v) ratios, and these extracts can then be combined.

[0145] In a method related to thin-layer chromatography, the chromatography may include the steps of fractionating the fungal hyphae by total lipid extract thin-layer chromatography and selecting a fraction having a retention factor (Rf) greater than that of the ceramide fraction and less than that of the nonpolar phospholipid fraction.

[0146] In certain methods relating to thin-layer chromatography, the chromatography may include the steps of: fractionating fungal hyphae and / or conidia of a fungus (e.g., Botrytis cinerea or other fungi) by total lipid extract thin-layer chromatography using a chloroform / methanol mixture (e.g., 85 / 15% v / v) as the eluent on silica-coated glass; and selecting a fraction having a retention factor (Rf) greater than that of the ceramide fraction and less than that of the nonpolar phospholipid fraction.

[0147] In a method relating to normal-phase flash chromatography, the chromatography may include the steps of fractionating the hyphae and / or conidia of a fungus (e.g., Botrytis cinerea or other fungi) by total lipid extract normal-phase flash chromatography, and selecting a fraction having a retention factor (Rf) greater than that of the ceramide fraction and less than that of the nonpolar phospholipid fraction.

[0148] In certain methods relating to normal-phase flash chromatography, the chromatography may include the steps of: dissolving the TLE in dichloromethane (CH2Cl2) and MeOH, and fractionating the hyphae and / or conidia of a fungus (e.g., Botrytis cinerea or other fungi) by total lipid extract normal-phase flash chromatography using CH2Cl2 / MeOH (e.g., 85 / 15%, v / v) as the eluent; and then filtering the fraction.

[0149] In certain methods relating to normal-phase flash chromatography, the chromatography may include the steps of: dissolving the TLE in dichloromethane (CH2Cl2) and MeOH; loading the TLE into a normal-phase flash cartridge (e.g., a flash cartridge packed with 15 μm particles); and delivering CH2Cl2 / MeOH (85 / 15%, v / v) as the eluent to the column by total lipid extract normal-phase flash chromatography to fractionate the hyphae and / or conidia of a fungus (e.g., Botrytis cinerea or other fungi); filtering the fraction through a filter (e.g., a 0.45 μm syringe filter fitted with a nylon membrane); and drying the fraction.

Provides polypeptides containing the following:

[0162] In certain embodiments, the CDR3 region is readily substituted without loss of activity (as demonstrated by replacing the CDR3 region with an unrelated CDR3, i.e., one that does not bind to fungi), so the polypeptide may contain only the specific CDR1 and CDR2 sequences of the polypeptide. Therefore, the CDR3 region sequence is arbitrary. Generally, the polypeptide may contain a CDR3 region (for example, to ensure structural integrity), but the sequence of the CDR3 region is not particularly important. For example, the polypeptide may contain a CDR1 region, a CDR2 region, and a CDR3 region, where the CDR1 and CDR2 regions each contain or consist of the sequences specified in this application, but the CDR3 region contains an arbitrary sequence (for example, any sequence having a length of 8 to 16 amino acids).

[0163] The polypeptide described in this application is preferably having a predetermined framework region sequence. For example, the polypeptide may include a framework region 1 (FR1) sequence that includes or is composed of a sequence selected from the group consisting of SEQ ID NOs: 149, 150, 154, 155, 158, and 159; a framework region 2 (FR2) sequence that includes or is composed of a sequence selected from the group consisting of SEQ ID NOs: 151, 156, and 160; a framework region 3 (FR3) sequence that includes or is composed of a sequence selected from the group consisting of SEQ ID NOs: 152, 157, and 161; and a framework region 4 (FR4) sequence that includes or is composed of SEQ ID NO: 153.

[0167] The CDR area and the framework area can be defined according to the Kabat numbering system.

[0168] In certain embodiments, the polypeptide can have a length of 80 to 200 residues.

[0169] The polypeptide of the present invention can be provided as a composition (for example, a pesticide composition).

Importantly, by thus interacting with the specific molecular structure of the pest, the composition disclosed herein is capable of inhibiting, interfering with, or suppressing one or more biological activities of the plant pathogen so as to inhibit, interfere with, or suppress the growth of the plant pathogen. In a given embodiment, the pesticide composition disclosed herein is capable of killing plant pests by specific interactions of at least one polypeptide contained in the composition that is capable of specifically binding to the pest.

Furthermore, it is preferable that such polypeptide sequences are selected to contain immunoglobulin folds or to form immunoglobulin folds under appropriate conditions.

[0174] In certain embodiments, the present invention provides a pesticide composition or biological pest control composition for controlling plant pests, more specifically plant fungi, wherein the composition contains at least one polypeptide or amino acid sequence of 80 to 200 amino acids as an active substance. In this application, "80 to 200 amino acids" means from 80 to 200, that is, including amounts of 80 amino acids and 200 amino acids. Therefore, "80 to 200 amino acids" can be used synonymously with "from 80 amino acids to 200 amino acids."

[0175] In another specified embodiment, the present invention provides a composition for controlling plant pests that contains at least two (different) polypeptides or at least two (different) amino acid sequences having 80 to 200 amino acids as an active substance.

[0178] The polypeptides or amino acid sequences contained in the compositions disclosed herein may be natural polypeptides or amino acid sequences, may be derived from natural polypeptides, or may be entirely artificially designed or synthesized. The polypeptides or amino acid sequences may be immunoglobulin-based, or, but are not limited to, domains present in proteins such as microbial proteins, protease inhibitors, toxins, fibronectin, lipocalin, single-stranded antiparallel coiled-coil proteins, or repeat motif proteins. Non-limiting examples of such polypeptides within the amino acid length range described in this application include carbohydrate-binding domains (CBDs) (Blake et al (2006) J. Biol. Chem. 281, 29321-29329), heavy chain antibodies (hcAb), single-domain antibodies (sdAb), minibodies (Tramontano et al (1994) J. Mol. Recognition 7, 9-24), variable domains of camel heavy chain antibodies (VHH), variable domains of novel antigen receptors (VNAR), afibodies (Nygren PA (2008) FEBS J. 275, 2668-2676), alphabodies (see WO2010066740), artificial ankyrin repeat domains (DARPins) (Stumpp et al (2008) Drug Discovery Today 13, 695-701), and antikarin (Skerra et al.

In particular, the polypeptides or amino acid sequences disclosed herein consist of a single polypeptide chain and are not post-translationally modified. More specifically, the polypeptides or amino acid sequences disclosed herein are derived from the innate or adoptive immune system, preferably from proteins of the innate or adoptive immune system. Even more specifically, the polypeptides or amino acid sequences disclosed herein are derived from immunoglobulins.Most specifically, the polypeptide or amino acid sequence disclosed herein comprises four framework regions and three complementarity-determining regions, or any suitable fragment thereof (usually including at least a portion of the amino acid residues that form at least one of the complementarity-determining regions). In particular, the polypeptide or amino acid sequence disclosed herein is preferably readily produced in high yield in a microbial recombinant expression system and is convenient for subsequent isolation and / or purification. In particular, the polypeptide or amino acid sequence disclosed herein comprises DARPins, Nottin, Alpha Body and V. HH Selected from the group consisting of the following. More specifically, the polypeptide or amino acid sequence disclosed herein is an alpha body and V HH Selected from the group consisting of the following. Most specifically, the polypeptide or amino acid sequence disclosed herein is V HH That is the case.

[0179] In particular, the at least one polypeptide contained in the compositions disclosed herein may consist of a single polypeptide chain and may not be post-translationally modified. More specifically, the at least one polypeptide contained in the compositions disclosed herein may be derived from the innate immune system or the adoptive immune system, preferably from proteins of the innate or adoptive immune system. Even more specifically, the at least one polypeptide contained in the compositions disclosed herein may be derived from an immunoglobulin. Most specifically, the at least one polypeptide contained in the compositions disclosed herein may contain four framework regions and three complementarity-determining regions, or any suitable fragment thereof (which typically includes at least a portion of amino acid residues forming at least one of the complementarity-determining regions). In particular, the at least one polypeptide contained in the compositions disclosed herein is preferably readily produced in high yield in a microbial recombinant expression system and is convenient for subsequent isolation and / or purification.

[0180] According to certain embodiments, the present invention provides a number of amino acid residue stretches (i.e., low molecular weight peptides) particularly suitable for binding to harmful organism antigens or harmful organism targets (but not limited to, for example, fungal antigens or fungal targets).

[0181] These amino acid residue stretches may be present in and / or incorporated into the polypeptide, in particular, to form (part of) the antigen-binding site of the polypeptide disclosed herein. These amino acid residue stretches may be used to bind antibodies such as heavy chain antibodies produced against harmful biological targets or V H Or V HH Since these amino acid residue stretches were initially constructed as CDR sequences (or, as detailed in this application, may be based on and / or derived from such CDR sequences), these amino acid residue stretches are also generally referred to in this application as "CDR sequences" (i.e., CDR1, CDR2, and CDR3 sequences, respectively). However, it should be noted that the present invention, in its broadest sense, is not limited to any specific structural role or function that these amino acid residue stretches may have in the polypeptide disclosed in this application, as long as these amino acid residue stretches enable the polypeptide disclosed in this application to specifically bind to harmful organism targets such as fungal antigens or fungal targets. Therefore, the present invention, in its broadest sense, generally relates to a pesticide composition containing a polypeptide that can bind to harmful organism targets such as fungal antigens or fungal targets and includes a combination of CDR sequences as described in this application.

[0182] Accordingly, in certain non-limiting embodiments, the polypeptide disclosed herein may be a polypeptide comprising at least one amino acid sequence selected from the group consisting of the CDR1, CDR2, and CDR3 sequences described herein. In particular, the polypeptide disclosed herein may comprise at least one antigen-binding site, the antigen-binding site comprising at least one combination of the CDR1, CDR2, and CDR3 sequences described herein.

[0183] All polypeptides contained in the pesticide compositions disclosed herein, having one of these CDR sequence combinations, are selected to be able to specifically bind (as defined herein) to a pest target or pest antigen, more specifically, in particular in solution the polypeptide 10 -8 It is preferable that the compound can specifically bind to the plant pathogen target with a dissociation constant (Kd) of moles / liter or less.

[0184] The dissociation constant (Kd) can be estimated based on the ELISA results. In equilibrium analyses such as ELISA, Kd can be calculated from the equilibrium binding response. If the target antigen is coated into ELISA plate wells and the target antigen may be a lipid-containing fraction of the Botrytis cinerea membrane, such a method can further use polypeptides in a concentration range that binds to the target antigen. If ELISA generally provides quantitative adsorption measurements of each polypeptide concentration representing the binding of the polypeptide to the target antigen, the concentration range of the polypeptide can be, for example, 0.5 μM, 1 μM, 2.5 μM, 5 μM, and 10 μM. The optimal concentration range used may vary depending on the affinity of the polypeptide to the target antigen. Plotting the absorption values ​​against a logarithmic transformation of the polypeptide concentration yields a sigmoid curve from the corresponding absorption values ​​measured by ELISA. The IC50 value can be determined using this sigmoid curve. If IC50 is the polypeptide concentration and the corresponding absorption value is 50% of the saturation value estimated by the maximum value of the sigmoid function, then Kd can be estimated by 1 / Ka, where the association constant (Ka) can be estimated as 1 / IC50. Thus, Kd corresponds to the analyte concentration that reaches equilibrium at 50% binding saturation. Generally, computer calculations can be used for these calculations. For example, this can be done using GraphPad. In certain embodiments, Kd can be measured by surface plasmon resonance (SPR).

[0185] The IC50 can be, for example, the IC50 for inhibiting spore germination and / or mycelial growth of Fusarium oxysporum and / or Botrytis cinerea (i.e., a concentration (μM) that inhibits 50% of spore germination and / or mycelial growth). In certain embodiments, the polypeptide has an IC50 for inhibiting spore germination and / or mycelial growth of less than about 10 μM, for example, less than about 1 μM.

[0186] The Kd can be the Kd of binding to a lipid-containing fraction (i.e., a lipid-containing fraction obtained by chromatography, which may be derived from a fungus such as Fusarium oxysporum or Botrytis cinerea) as can be obtained as otherwise described in this application. The Kd of the polypeptide can be less than about 10 μM, for example, less than about 1 μM. The Kd can be determined by any suitable method. For example, the Kd can be determined by biolayer interference (BLI) in Octet, for example. The assay used to determine the Kd can be an ELISA assay.

[0187] The specific binding of polypeptides to harmful organism targets can be confirmed by any suitable method known in itself, such as biopanning, scatchard analysis and / or competitive binding assays such as radioimmunoassay (RIA), enzyme immunoassay (EIA), and sandwich competitive assays, as well as various modifications thereof known in the art.

[0188] In one preferred embodiment, a polypeptide of 80 to 200 amino acids is obtained by affinity selection for a specific pest target molecule, the polypeptide has high affinity for the pest target molecule, and generally the dissociation constant of the binding of the polypeptide to the pest target molecule is 10 -5 M is less than 10 -6 A value less than M is more preferable, and the dissociation constant is 10 -7 It is even more preferable that the dissociation constant is less than M, and the dissociation constant is 10 -8 Less than M is most preferable.

[0189] In certain embodiments, the at least one polypeptide contained in the composition disclosed herein has a minimum inhibitory concentration (MIC) value of 1.0 μg / mL or less of the variable domain in solution against the plant pathogenic fungus.

[0190] Also disclosed are polypeptides of 80 to 200 amino acids or subranges as disclosed above, obtained by affinity selection for specific plant pest targets, capable of inhibiting the growth and / or activity of crop pests at minimum inhibitory concentrations of approximately 0.00001 to 1 μM. In certain embodiments, the minimum inhibitory concentration is 0.0001 to 1 μM, 0.001 to 1 μM, 0.01 to 1 μM, 0.1 to 1 μM, 0.0001 to 0.1 μM, 0.001 to 0.1 μM, 0.01 to 0.1 μM, 0.00001 to 0.01 μM, 0.0001 to 0.01 μM, or 0.001 to 0.01 μM. In other specific embodiments, the minimum inhibitory concentration is approximately 0.0001 to 1 μM, approximately 0.001 to 1 μM, approximately 0.01 to 1 μM, approximately 0.1 to 1 μM, approximately 0.0001 to 0.1 μM, approximately 0.001 to 0.1 μM, approximately 0.01 to 0.1 μM, approximately 0.00001 to 0.01 μM, approximately 0.0001 to 0.01 μM, or approximately 0.001 to 0.01 μM.

[0191] The minimum inhibitory concentration (MIC) is the lowest concentration of a substance, such as a polypeptide, that inhibits the visible growth of the crop or plant pest after incubation. For example, the minimum fungicidal concentration (MFC) is considered to be the lowest concentration of polypeptide that inhibits the growth of fungal inoculum within 24 hours and reduces the inoculum by at least 99-90%. The MFC (minimum fungicidal concentration) can be measured on an agar plate, but it can also be measured conventionally in liquid (e.g., on a microwell plate) depending on the type of fungus and assay conditions.

Such substitutions can generally be made in the CDR region, for example, the CDR1 region, the CDR2 region, or the CDR3 region.

[0207] Other substitutions may be made to the polypeptide. For example, substitutions that do not affect the overall charge of the polypeptide can be made. The inventors unexpectedly found that an increase in positive charge can correlate with an improvement in antifungal activity, so it is advantageous to make substitutions that do not decrease the total charge of the polypeptide.

[0208] Other substitutions are also possible. For example, the polypeptide may begin with a D residue or a Q residue. The inventors have found that while Q can be used for the residue at position 1 of the polypeptide (i.e., the first residue of the framework 1 region sequence), using D can improve the antifungal properties of the polypeptide. Therefore, for all specific polypeptide sequences disclosed herein (including all peptides having any one of the sequences of SEQ ID NOs: 1-51 or 101-111), the residue at position 1 may be a Q residue, but in certain embodiments, it is preferable to use a D residue. The designation of a polypeptide such as 10G11Q indicates that the polypeptide begins with a Q residue. The designation of a polypeptide such as 10G11 (without Q at the end) indicates that the polypeptide begins with a D residue. In this application, 10G11 may also be referred to as 10G11Q1D (a notation indicating the substitution of Q to D at position 1).

[0209] In certain embodiments, the present invention provides polypeptides comprising or composed of amino acid sequences having at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, or at least about 98% identity with any of the amino acid sequences selected from the group consisting of SEQ ID NOs: 1 to 51. All polypeptides having a specific percentage of sequence identity with a given SEQ ID NO may have the same total charge as the reference sequence, or may have more positive charge than the reference sequence. It is advantageous that all polypeptides having a specific percentage of sequence identity with a given SEQ ID NO may not have more negative charge than the reference sequence.

[0210] In certain embodiments, the present invention provides a polypeptide comprising an amino acid sequence selected from the group consisting of SEQ ID NOs: 1 to 51, or an amino acid sequence having up to one, two, three, four, or five amino acid substitutions in the said sequence, or comprising such a sequence.

[0211] In certain embodiments, the present invention provides polypeptides comprising or composed of amino acid sequences having at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, or at least about 98% identity with any of the amino acid sequences selected from the group consisting of SEQ ID NOs: 1-10 and 12-51. All polypeptides having a specific percentage of sequence identity with a given SEQ ID NO may have the same total charge as the reference sequence, or may have more positive charge than the reference sequence. It is advantageous that all polypeptides having a specific percentage of sequence identity with a given SEQ ID NO may not have more negative charge than the reference sequence.

[0212] In certain embodiments, the present invention provides a polypeptide comprising an amino acid sequence selected from the group consisting of SEQ ID NOs: 1 to 10 and 12 to 51, or an amino acid sequence having up to one, two, three, four, or five amino acid substitutions in the said sequence, or comprising such a sequence.

[0213] In certain embodiments, the present invention provides polypeptides comprising or composed of amino acid sequences having at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, or at least about 98% identity with any of the amino acid sequences selected from the group consisting of SEQ ID NOs: 1 to 6. All polypeptides having a specific percentage of sequence identity with a given SEQ ID NO may have the same total charge as the reference sequence, or may have more positive charge than the reference sequence. It is advantageous that all polypeptides having a specific percentage of sequence identity with a given SEQ ID NO may not have more negative charge than the reference sequence.

[0214] In certain embodiments, the present invention provides a polypeptide comprising an amino acid sequence selected from the group consisting of SEQ ID NOs: 1 to 6, or an amino acid sequence having up to one, two, three, four, or five amino acid substitutions in the said sequence, or comprising such a sequence.

[0215] All amino acid substitutions in the polypeptide may increase the total charge of the polypeptide, or they may not change the total charge of the polypeptide. In certain embodiments, no amino acid substitutions decrease the total charge of the polypeptide.

[0216] All amino acid substitutions in the polypeptide may be located anywhere within the polypeptide sequence. Optionally, the amino acid substitutions may be restricted to the CDR region (in such embodiments, the polypeptide maintains the original framework region sequence), or they may not be restricted to the CDR region. In certain embodiments, all substitutions or mutations in the sequence may be located in the CDR region or in any of the two amino acid residues on either side of the CDR region (as defined by the Kabat numbering system). In certain embodiments, all substitutions or mutations in the sequence may be located in the CDR region or in any of the one amino acid residues on either side of the CDR region (as defined by the Kabat numbering system). In certain embodiments, all substitutions or mutations in the sequence may be located in the CDR region or in the residue adjacent to the N-terminus of the CDR3 region (as defined by the Kabat numbering system).

[0217] The present invention provides specific mutants, referred to hereby as mutants 1 to 5, (in which the total charge of the polypeptide has been modified to investigate the functional effects on the polypeptide), and mutants, referred to hereby as "single ALA mutants" 1 to 34, which have substitutions other than alanine but were subjected to alanine scanning. The present invention also extends to other mutants or variants of the polypeptide sequence disclosed here, for example, those having other substitutions, or various combinations of substitutions, or those having substitutions at various positions in the polypeptide sequence. It is appropriate that any mutant or variant of the polypeptide sequence disclosed here does not decrease the positive charge compared to the reference sequence. In some cases, mutants or variants of the polypeptide sequence disclosed here can increase the total positive charge.

[0218] The total charge of the polypeptide can be calculated before and after substitution or mutation, and the charge of the polypeptide is calculated in an aqueous solution at the same pH before and after introducing substitution or mutation into the sequence.

[0219] The total charge of the polypeptide can be calculated according to any suitable method known to those skilled in the art. For example, the charge can be calculated using a free online tool such as ExPASy-ProtParam (https: / / web.expasy.org / protparam / ).

[0220] The charge of the polypeptide is preferably calculated at pH 7. Generally, the polypeptide will have a positive total charge (at pH 7). It is preferable that the substitution or mutation in the sequence does not decrease the total charge (at pH 7). In certain embodiments, the substitution or mutation in the sequence will increase the positive total charge of the polypeptide (at pH 7).

[0221] The charge or total charge of the polypeptide will affect the isoelectric point (pI) of the polypeptide. The isoelectric point of a polypeptide is the pH at which the molecule has no net charge. Generally, the polypeptide is judged to have a pI greater than 7 and a positive total charge at pH 7. It is preferable that the pI does not decrease due to substitution or mutation in the sequence. In certain embodiments, the pI will increase due to substitution or mutation in the sequence.

[0222] The present invention also provides a polypeptide (and a composition containing the polypeptide) having a predetermined sequence capable of mutation or substitution at a specific position. Such mutants include those referred to as 10G11-A to 10G11-K in the present application.

[0223] For example, in one embodiment, the present invention provides the following sequence:

(SEQ ID NO: 111).

[0245] All polypeptides disclosed in the present application, including their variants, can be formulated into a composition (e.g., an agrochemical composition).

[0246] Generally, the present invention also encompasses variants of the polypeptide, provided that the polypeptide can maintain its functional properties or improve its functional properties. For example, the variant may be capable of (specifically) binding to a fungus. More specifically, the variant may be capable of (specifically) binding to a fungal membrane or a component of a fungal membrane. In certain embodiments, the variant does not bind to the fungal cell wall or a component of the cell wall. For example, in certain embodiments, the variant polypeptide does not (specifically) bind to fungal glucosylceramide.

[0247] The aforementioned mutant may be able to bind to the lipid-containing fraction of the cell membrane of a fungus (e.g., Botrytis cinerea or other fungi). The lipid-containing fraction may be obtainable by chromatography. For example, the lipid-containing fraction may be obtainable by a method comprising the steps of fractionating the hyphae of a fungus (e.g., Botrytis cinerea or other fungi) by total lipid extract thin-layer chromatography, and selecting a fraction having a retention factor (Rf) greater than that of the ceramide fraction and less than that of the nonpolar phospholipid fraction.

[0248] The mutant can further cause delayed growth of fungal spores and / or lysis of the fungal spores. That is, the mutant polypeptide binds to the fungus, resulting in delayed growth of the fungal spores and / or lysis of the fungal spores.

[0249] In certain embodiments, the mutant can cause delayed fungal spore growth and / or lysis of fungal spores with an IC50 less than or equal to that of a reference polypeptide when measured under substantially identical conditions. The IC50 can be, for example, a concentration (μM) that inhibits 50% of Fusarium oxysporum spore germination and / or mycelial growth.

[0250] In certain embodiments, the variant can (specifically) bind to fungi (e.g., fungal membranes or components of fungal membranes) with a KD of less than or equal to that of the reference polypeptide when measured under substantially the same conditions.

[0251] In certain embodiments, the mutant can (specifically) exhibit an MIC below that of the reference polypeptide for fungal growth when measured under substantially identical conditions.

[0252] In a predetermined embodiment, the polypeptide contained in the pesticide composition disclosed herein may optionally be functionally linked to one or more other groups, moieties, or residues via one or more linkers. These one or more other groups, moieties, or residues may play a role in binding to other applicable targets. Naturally, such other groups, residues, moieties, and / or binding sites may or may not provide other functionality to the polypeptide disclosed herein (and / or the composition in which the polypeptide is contained), nor may they alter the properties of the polypeptide disclosed herein. Such groups, residues, moieties, or binding sites may, for example, be chemical groups that may be biologically active.

[0253] These groups, parts, or residues can, in certain embodiments, be linked to the N-terminus or C-terminus of the polypeptide in the composition disclosed herein.

[0254] In certain embodiments, the polypeptide in the pesticide composition disclosed herein may be chemically modified. For example, such modification may involve introducing or linking one or more functional groups, residues, or moieties to the heavy chain variable domain. These groups, residues, or moieties can impart one or more desirable properties or functions to the polypeptide. Examples of such functional groups will be obvious to those skilled in the art.

[0255] For example, introducing or linking such functional groups to a polypeptide can improve the solubility and / or stability of the polypeptide, reduce the toxicity of the polypeptide, eliminate or mitigate undesirable side effects of the polypeptide, and / or obtain other advantageous properties.

[0256] In certain embodiments, the one or more groups, residues, or moieties are linked to the polypeptide via one or more suitable linkers or spacers.

[0257] In other specific embodiments, two or more target-specific polypeptide molecules in the pesticide compositions disclosed herein can be linked or bonded together. In specific embodiments, the two or more polypeptide molecules are linked together via one or more suitable linkers or spacers. Suitable spacers or linkers for use in coupling the various heavy-chain polypeptides disclosed herein are obvious to those skilled in the art and can be any linker or spacer commonly used in the art to link peptides and / or proteins.

[0258] Particularly suitable linkers or spacers include, but are not limited to, glycine linkers, serine linkers, mixed glycine / serine linkers, glycine-rich linkers, serine-rich linkers, or polypeptide linkers mainly composed of polar polypeptide fragments, glutaraldehyde, or optionally homo- or hetero-bifunctional chemical crosslinking compounds such as maleimide or NHS esters via PEG spacers.

[0259] For example, the polypeptide linker or spacer can be a suitable amino acid sequence having a length of 1 to 50 amino acids, such as 1 to 30, particularly 1 to 10 amino acid residues. Naturally, the length, degree of flexibility, and / or other properties of the linker will have some influence on the properties of the polypeptide, including, but not limited to, affinity, specificity, or avidity to harmful organism targets. Naturally, if two or more linkers are used, these linkers may be the same or different. In the context and disclosure of the present invention, those skilled in the art will be able to determine the optimal linker for coupling the heavy chain variable domain disclosed herein without bearing an excessive burden of experimentation.

[0260] Composition containing a polypeptide sequence fragment The present invention also includes parts, fragments, analogs, mutants, variants, and / or derivatives of polypeptides contained in the compositions disclosed herein, and / or polypeptides containing one or more such parts, fragments, analogs, mutants, variants, and / or derivatives, provided that these parts, fragments, analogs, mutants, variants, and / or derivatives are suitable for the purposes envisioned herein. Such parts, fragments, analogs, mutants, variants, and / or derivatives according to the present invention can also specifically bind to harmful organism targets (e.g., fungi such as plant pathogenic fungi).

[0261] target In certain embodiments, polypeptides contained in the compositions disclosed herein are obtained by affinity selection for specific harmful organism targets, such as fungal antigens or fungal targets. To obtain suitable polypeptides by affinity selection for specific pest targets, this can be carried out, for example, by screening a set, collection, or library of cells (e.g., bacteriophages) expressing polypeptides on their surface for binding to pest target molecules known in the art to be targets of pest control agents. All of these steps can be carried out by methods known in themselves and essentially include the following non-limiting steps: a) obtaining an isolated solution or suspension of pest target molecules known to be targets of pest control agents; b) biopanning phages or other cells from a polypeptide library against the target molecules; c) isolating phages or other cells that bind to the target molecules; d) determining the nucleotide sequences encoding polypeptide inserts from individual binding phages or other cells; e) producing a corresponding amount of polypeptide using recombinant protein expression; f) measuring the affinity of the polypeptide to the pest target; and optionally, g) testing the pest control activity of the polypeptide in a bioassay of the pest. Various methods can be used to measure the affinity between the polypeptide and the pest target molecule. For example, enzyme immunosorbent assay (ELISA) or surface plasmon resonance (SPR) assay, which are common methods in the art, can be used, as described in Sambrook et al. (2001), Molecular Cloning, A Laboratory Manual, Third Edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY. Dissociation constants are widely used to express the affinity between a polypeptide and its pest target molecule. Generally, the dissociation constant for the binding of a polypeptide to its pest target molecule is 10 -5 M is less than 10 -6 M is more preferably less than M, and the dissociation constant is 10 -7It is even more preferable that the dissociation constant is less than M, and the dissociation constant is 10 -8 Less than M is most preferable.

[0262] The harmful organism target molecules disclosed herein are molecules that are present inside or on the surface of harmful organisms, and when bound to and / or inhibited, cause the harmful organism to die or inhibit, suppress, or inhibit its growth or activity. Such suitable target molecules are readily searchable by those skilled in the art from existing literature or patent databases and are not limited to those listed above. Examples include secretory parasitic proteins such as 16D10 as a suitable target molecule for root-knot nematodes (Huang et al (2006) PNAS 103:14302-14306), V-ATPase proton pump as a suitable target molecule for insect species of the Coleoptera (beetles), Hemiptera (true bugs), and Diptera (flies), and nematodes (Knight AJ and Behm CA (2011) Ex. Parasitol. Sept 19), and tetraspanin PLS1 as a suitable target molecule for the fungal pests of gray mold (B. cinerea) and rice blast (M. grisea) (Gourgues et al. Examples of antifungal targets include proton pump ATPases (Manavathu EK et al (1999) Antimicrob Agents and Chemotherapy, Dec p.2950), or (2002) Biochem. Biophys. Res. Commun. 297:1197). Naturally, preferred pest target molecules are accessible in the extracellular space (in contrast to intracellular pest targets).

[0263] More specifically, the pest target to which the at least one polypeptide of the pesticide composition disclosed herein is bound may be a cell membrane component of a pest. The cell membrane component of a pest used in this application may be any component that is included in or part of either the cell membrane phospholipid bilayer or a protein embedded in the phospholipid bilayer of the pest's cell (i.e., at least a portion of which is associated with, present in, linked to, or bound to the phospholipid bilayer). In certain embodiments, the cell membrane component of a pest may be a phospholipid, glycoprotein, carbohydrate, or cholesterol.

[0264] In certain embodiments, the cell membrane component of a harmful organism to which the at least one polypeptide in the composition disclosed herein specifically binds is a non-protein.

[0265] Therefore, in certain embodiments, the cell membrane component of a harmful organism to which the at least one polypeptide in the composition disclosed herein specifically binds is, for example, a lipid such as a phospholipid, carbohydrate, or cholesterol.

[0266] In a specific embodiment of the present invention, the target to which the polypeptide in the pesticide composition binds is something other than a cell wall component.

[0267] In a specific embodiment of the present invention, the target to which the polypeptide in the pesticide composition of the present invention binds is something other than chitin.

[0268] In a preferred embodiment, the plant pests controlled by the pesticide composition or biological control composition disclosed herein are fungi, such as the plant pathogenic fungi defined above. Fungi are highly harmful to plants and can lead to a substantial reduction in crop yield. Examples of plant pathogenic fungi include necrotic fungi and vitrophotactic fungi, and include ascomycetes, basidiomycetes, and oomycetes.

[0269] Examples of plant pathogenic fungi are known in the art and are not limited to, but include: Alternaria, Ascochyta, Botrytis, Cercospora, Colletotrichum, Diplodia, Erysiphe, Fusarium, Leptosphaeria, Gaeumanomyces, Helminthosporium, Macrophomina, Nectria, Oidium, Peronospora, Phakopsora, and Phoma.

[0369] As will be obvious to those skilled in the art, one example of a particularly useful method for producing the polypeptide sequences disclosed herein is generally, (a) A step of expressing a nucleotide sequence encoding a polypeptide sequence disclosed herein or a vector or gene construct comprising a nucleotide sequence encoding the polypeptide, (b) optionally comprising the step of isolating and / or purifying the polypeptide sequence.

[0370] In a particular embodiment envisioned in this application, the pest-specific polypeptide sequence can be obtained by a method comprising the steps of preparing a random library of amino acid sequences and screening this library for amino acid sequences that can specifically bind to a pest target.

[0371] Therefore, in a particular embodiment, the method for producing the polypeptide sequence disclosed herein is a) A step of preparing a set, collection, or library of amino acid sequences; b) A step of screening the set, collection or library for amino acid sequences that bind to and / or have affinity for the pest target; c) The process includes the step of isolating an amino acid sequence that binds to and / or has affinity for the pest target.

[0372] In such a method, the set, collection, or library of polypeptide sequences may be any suitable set, collection, or library of amino acid sequences. For example, the set, collection, or library of amino acid sequences may be a set, collection, or library of immunoglobulin fragment sequences (as described in this application), such as a naive set, collection, or library of immunoglobulin fragment sequences; a synthesized or semi-synthetic set, collection, or library of immunoglobulin fragment sequences; and / or a set, collection, or library of immunoglobulin fragment sequences subjected to affinity maturation.

[0373] In certain embodiments of this method, the set, collection, or library of amino acid sequences may be, for example, an immunization set, collection, or library of immunoglobulin fragment sequences derived from mammals appropriately immunized with a hazardous organism target or a suitable antigenic determinant (e.g., its antigenic portion, fragment, region, domain, loop, or other epitope) based on or derived from a hazardous organism target. In one particular embodiment, the antigenic determinant may be an extracellular portion, region, domain, loop, or other extracellular epitope.

[0374] In the above method, the set, collection, or library of polypeptide sequences can be presented on the surface of a phage, phagemid, ribosome, or suitable microorganism (e.g., yeast) for purposes such as facilitating screening. Suitable methods, techniques, and host organisms for presenting and screening amino acid sequences (sets, collections, or libraries) are obvious to those skilled in the art, for example, based on the detailed disclosure of this application. See also the article by Hoogenboom in Nature Biotechnology, 23, 9, 1105-1116 (2005).

[0375] In other embodiments, the method for producing the polypeptide sequence disclosed herein is: a) A step of preparing a cell collection or sample expressing a polypeptide sequence; b) A step of screening the cell collection or sample for cells that express amino acid sequences capable of binding to and / or having affinity for harmful organism targets; c) The method includes at least the steps of (i) isolating the amino acid sequence, or (ii) expressing the amino acid sequence after isolating the nucleic acid sequence encoding the amino acid sequence from the cell.

[0376] The cell collection or sample may be, for example, a collection or sample of B cells. Furthermore, in this method, the cell sample may be derived from mammals appropriately immunized with a fungal target or a suitable antigenic determinant (e.g., its antigenic portion, fragment, region, domain, loop, or other epitope) based on or derived from a fungal target. In one particular embodiment, the antigenic determinant may be an extracellular portion, region, domain, loop, or other extracellular epitope.

[0377] In another embodiment, a method for producing polypeptide sequences specific to harmful organism targets is: a) the step of preparing a set, collection, or library of nucleic acid sequences encoding polypeptides or amino acid sequences; b) A step of screening the set, collection, or library of nucleic acid sequences for nucleic acid sequences that can bind to and / or have affinity for the pest target; c) The process may include at least the step of expressing the amino acid sequence after isolating the nucleic acid sequence.

[0378] In the above method, the harmful organism target can be the lipid-containing fraction of the cell membrane of a fungus (e.g., Botrytis cinerea or other fungi). The lipid-containing fraction may be obtained by chromatography. For example, the lipid-containing fraction may be obtained by a method comprising the steps of fractionating the hyphae of a fungus (e.g., Botrytis cinerea or other fungi) by total lipid extract thin-layer chromatography, and selecting a fraction whose retention factor (Rf) is greater than that of the ceramide fraction and less than that of the nonpolar phospholipid fraction.

[0379] In the above method, the set, collection or library of nucleic acid sequences encoding amino acid sequences can be, for example, a naive set, collection or library of immunoglobulin fragment sequences, a set, collection or library of nucleic acid sequences encoding the same; a synthetic or semi-synthetic set, collection or library of immunoglobulin fragment sequences, a set, collection or library of nucleic acid sequences encoding the same; and / or a set, collection or library of nucleic acid sequences encoding immunoglobulin fragment sequences that have been subjected to affinity maturation, a set, collection or library of nucleic acid sequences encoding the same.

[0380] In particular, in such a method, the set, collection or library of nucleic acid sequences encodes a set, collection or library of polypeptides (such as V H domains or V HH domains). For example, the set, collection or library of nucleic acid sequences can encode a set, collection or library of domain antibodies or single domain antibodies, or a set, collection or library of amino acid sequences capable of functioning as domain antibodies or single domain antibodies. In certain embodiments, the set, collection or library of nucleotide sequences encodes a set, collection or library of V HH sequences.

[0381] In the above method, for the purpose of facilitating screening, etc., the set, collection or library of nucleotide sequences can be displayed on the surface of phage, phagemid, ribosome or a suitable microorganism (such as yeast). Methods, techniques and host organisms suitable for presenting and screening nucleotide sequences (sets, collections or libraries) encoding amino acid sequences will be apparent to those skilled in the art based on, for example, the detailed disclosure of the present application. See also the review by Hoogenboom in Nature Biotechnology, 23, 9, 1105-1116 (2005).

[0382] The present invention further relates to polypeptide sequences that can be obtained by the above method, or comprising one of the above methods, and further comprising the steps of: determining at least the nucleotide sequence or amino acid sequence of the immunoglobulin sequence; and expressing or synthesizing the amino acid sequence by a method known in itself, such as expression in a host cell or host organism or by a chemical synthesis method.

[0383] Isolation of polypeptide sequences Depending on the circumstances, the method for producing amino acid sequences that specifically bind to fungal targets as envisioned in this application may further include the step of isolating from the amino acid sequence library at least one polypeptide having detectable binding affinity or detectable in vitro activity to a harmful organism target.

[0384] These methods may further include a step of amplifying a sequence encoding at least one polypeptide that has a detectable binding affinity to a toxic organism target or a detectable in vitro activity against that target. For example, a phage clone presenting a specific amino acid sequence obtained from the selection step of the methods described herein can be amplified by reinfection with a host bacterium and incubation in a growth medium.

[0385] In certain embodiments, these methods may include the step of determining the sequence of one or more amino acid sequences capable of binding to a pest target.

[0386] When polypeptide sequences contained in a set, collection, or library of amino acid sequences are presented on the surface of a suitable cell, phage, or particle, it is possible to isolate the nucleotide sequences encoding the amino acid sequences from the cell, phage, or particle. Thus, the nucleotide sequences of selected amino acid sequence library members can be determined by routine sequencing methods.

[0387] In other specific embodiments, the polypeptide production method envisioned in this application includes the step of expressing the nucleotide sequence in a host organism under appropriate conditions to obtain the actual desired amino acid sequence. This step can be carried out by methods known to those skilled in the art.

[0388] Furthermore, polypeptide sequences thus obtained that have detectable binding affinity to harmful organism targets or detectable in vitro activity against them can be optionally synthesized as soluble protein constructs after their sequences have been identified.

[0389] For example, polypeptide sequences obtained, obtainable, or selected by the above method can be synthesized using recombinant or chemical synthesis methods known in the art. Furthermore, amino acid sequences obtained, obtainable, or selected by the above method can also be produced by genetic recombination technology. Therefore, a method for synthesizing polypeptide sequences obtained, obtainable, or selected by the above method may include a step of transforming or infecting host cells with nucleic acids or vectors encoding amino acid sequences that have a detectable binding affinity to a pest target or a detectable in vitro effect on its activity. Thus, amino acid sequences that have a detectable binding affinity to a pest target or a detectable in vitro effect on its activity can be produced by recombinant DNA methods. DNA encoding amino acid sequences can be easily synthesized using conventional procedures. Once the DNA is produced, it can be introduced into an expression vector, and then the vector can be transformed or transfected into host cells such as E. coli or any suitable expression system to obtain expression of the amino acid sequence in recombinant host cells and / or in a culture medium containing these recombinant host cells.

[0390] Naturally, as is well known to those skilled in the field of protein expression and purification, polypeptides produced from expression vectors using a suitable expression system may be tagged with, for example, a His tag or other sequence tags to facilitate purification (generally at the N-terminus or C-terminus of the amino acid sequence).

[0391] Transformation or transfection of host cells with nucleic acids or vectors can be carried out by various means known to those skilled in the art, including calcium phosphate DNA coprecipitation, DEAE-dextran transfection, polyblen transfection, electroporation, microinjection, liposome fusion, lipofection, protoplast fusion, retroviral infection, and particle gun methods.

[0392] Suitable host cells for expressing the desired polypeptide sequence can be any eukaryotic or prokaryotic cell (e.g., bacterial cells such as E. coli, yeast cells, mammalian cells, avian cells, amphibian cells, plant cells, fish cells, and insect cells), regardless of whether they are located in vitro or in vivo. For example, the host cell can be located in a transgenic plant or animal.

[0393] Accordingly, the present invention further provides a method for producing a polypeptide sequence having a detectable binding affinity to a harmful organism target or a detectable in vitro activity against its activity, comprising the steps of transforming, transfecting, or infecting a host cell with a nucleic acid sequence or vector encoding such an amino acid sequence, and expressing the amino acid sequence under appropriate conditions. The present invention further provides a method for producing a polypeptide sequence having a detectable binding affinity to a harmful organism target or a detectable in vitro activity against its activity, comprising the steps of preparing a host cell into which the nucleic acid sequence or vector encoding the polypeptide has been introduced, and expressing the polypeptide under appropriate conditions. The method of the present invention may further include the step of isolating the polypeptide, for example, isolating the polypeptide from a cell culture medium or fermentation broth or from within the host cell (for example, after the step of lysing the host cell).

[0394] In yet another embodiment, the present invention further provides a method for producing (synonymously, "or manufacturing") the pesticide composition or biological control composition disclosed herein.

[0395] In certain embodiments, the present invention provides a method for producing the pesticide composition disclosed herein, - A step of obtaining at least one polypeptide that specifically binds to harmful organisms, The present invention provides a method comprising at least the step of formulating the polypeptide or a functional fragment thereof into a pesticide composition.

[0396] In certain embodiments of these methods, the step of obtaining at least one polypeptide that specifically binds to a pest is: (a) A step of expressing a nucleotide sequence encoding a polypeptide that specifically binds to harmful organisms, and optionally, (b) a step of isolating and / or purifying the polypeptide.

[0397] In other specific embodiments of these methods, the step of obtaining at least one polypeptide that specifically binds to a pest is: a) the process of preparing a set, collection, or library of polypeptide sequences; b) A step of screening the set, collection or library of polypeptide sequences for sequences that specifically bind to and / or have affinity for harmful organisms, and optionally, c) The process includes isolating the polypeptide sequence which specifically binds to and / or has affinity for harmful organisms.

[0398] The present application further provides a method for producing (or manufacturing) the pesticide composition or biological control composition disclosed herein, comprising the step of formulating an amino acid sequence or polypeptide of 80 to 200 amino acids or other suitable subranges defined above, which has pest control activity, together with at least one conventional pesticide adjuvant.

[0399] Suitable manufacturing methods are known in the art and are not limited to, but include high-shear or low-shear mixing, wet or dry grinding, drip casting, encapsulation, emulsification, coating, powder coating, pilling, extrusion granulation, fluid bed granulation, co-extrusion, spray drying, spray cooling, atomization, addition polymerization or polycondensation, interfacial polymerization, in situ polymerization, coacervation, spray encapsulation, melt dispersion cooling, solvent evaporation, phase separation, solvent extraction, sol-gel polymerization, fluid bed coating, pan coating, melting, and passive or active absorption or adsorption methods.

[0400] Specifically, the 80-200 amino acid sequences or polypeptides disclosed herein, or other suitable subranges defined above, can be produced by chemical synthesis.

[0401] Furthermore, it is disclosed that amino acid sequences or polypeptides of 80 to 200 amino acids or other suitable subranges defined above can be prepared in vitro using a recombinant microbial expression system and isolated for subsequent use. Such amino acid sequences or polypeptides may be in the form of crude cell lysates, suspensions, colloids, etc., or may be purified, decontaminated, buffered and / or further processed before formulation with conventional pesticide adjuvants.

[0402] Specifically, recombination generally involves inserting a DNA molecule expressing a target amino acid sequence, protein, or polypeptide into a heterologous expression system (i.e., such a DNA molecule is not normally present in the host). The heterologous DNA molecule is inserted into the expression system or vector in the correct orientation and reading frame. The vector contains the components necessary for the transcription and translation of the inserted protein coding sequence. DNA transcription depends on the presence of a promoter. Similarly, mRNA translation in prokaryotic cells depends on the presence of appropriate prokaryotic signals that differ from eukaryotic signals. For a discussion on maximizing gene expression, see Roberts and Lauer, Methods in Enzymology 68:473 (1979). Regardless of the specific regulatory sequence used, the DNA molecule is cloned into the vector using standard cloning procedures in the art, such as those described in Sambrook et al, Molecular Cloning: A Laboratory Manual, Cold Springs Laboratory, Cold Springs Harbor, NY (1989). Once the isolated DNA molecule encoding the protein is cloned into an expression system, it is ready for uptake by a host cell. Such uptake can be carried out by various transformation methods depending on the vector / host cell system. Suitable host cells include, but are not limited to, bacteria, viruses, yeast, mammalian cells, insects, and plants. Optionally, the recombinant host cell may be a host cell expressing a native or recombinant functional type III secretory system. This is described in detail in US6,596,509. As a result of expressing a functional type III secretory system, the cell will express the polypeptide and subsequently secrete the protein into the culture medium. This simplifies the isolation and purification of the polypeptide. The recombinant host cell can be grown in a suitable fermentation chamber, preferably under temperature and nutritional conditions that optimize host cell growth and polypeptide expression. Those skilled in the art can determine the optimal conditions for a particular host cell.After fermentation, the bacterial suspension can be diluted with, for example, about 2 to 5 times its volume of buffer to adjust the pH to about 5.5 to 10, more preferably about 7 to 9, and even more preferably about 8.0. Suitable buffers are well known in the art and include, for example, potassium phosphate buffer and Tris-EDTA buffer. The concentration of the buffer can be about 0.001 mM to about 0.5 M. After pH adjustment, the (bacterial) suspension is heat-treated to a temperature of about 60 to 130°C, preferably about 95 to 125°C. The heat treatment can be carried out for any suitable time. In one embodiment, the heat treatment is carried out for about 5 to 30 minutes. The heated suspension is then cooled. A suitable cooling temperature is not limited, but is about 35 to 55°C, preferably about 45°C. After cooling, the bacterial cells in the bacterial suspension are lysed as needed to release polypeptides. Cell lysis can be carried out, for example, by contacting the bacterial suspension with lysozyme. The concentration of lysozyme can be about 2 ppm to 100 ppm. Alternatively, cell lysis may be performed by non-chemical methods such as high pressure or sonication, both of which are well known to those with ordinary skill in the art. It is desirable to incubate the bacterial suspension after cell lysis. The appropriate incubation time can vary. For example, it is desirable to incubate the bacterial suspension at a temperature of about 40-42°C for about 30-45 minutes. After lysis, the desired polypeptide can be further extracted by removing cell debris and denatured proteins resulting from the heat treatment in the preceding step. In one embodiment, the extract is centrifuged for about 10-20 minutes to remove some of the cell debris. The appropriate centrifugal speed can be about 4,000-20,000 rpm, and the spin-down time can be about 10-20 minutes. Subsequently, further cell debris is removed by heat treatment and centrifugation of the supernatant, and a liquid extract substantially free of cell debris is obtained by removing more than 60%, 70%, 80%, 90%, or 95% of the total solids. The subsequent heat treatment can be carried out at a temperature of approximately 60°C for up to approximately 2 hours, at approximately 100°C for approximately 10 minutes, or at approximately 121°C for approximately 5 minutes under a pressure of 15 psi. These temperatures and times may vary depending on other conditions.A method for producing a stable liquid composition containing the amino acid sequence or polypeptide disclosed herein further comprises the steps of introducing a biocide and, optionally, one or both of a protease inhibitor and a nonionic surfactant into the liquid extract to obtain a liquid composition containing the polypeptide. In one embodiment, the protease inhibitor is introduced into the liquid extract without the addition of a nonionic surfactant. In another embodiment, the nonionic surfactant is introduced into the liquid extract without the addition of a protease inhibitor. In yet another embodiment, both the protease inhibitor and the nonionic surfactant are introduced into the liquid extract. In yet another embodiment, neither the protease inhibitor nor the nonionic surfactant is introduced into the liquid extract. Alternatively, the stability of the liquid composition disclosed herein can be evaluated using, for example, HPLC analysis or other suitable methods capable of quantifying the amount of a particular protein or polypeptide. The stability of the amino acid sequence or polypeptide in the composition disclosed herein can be measured by comparing the amount of protein in the matured liquid composition with the amount in the freshly prepared liquid composition or a previous quantitative determination performed with the same composition. Measuring protein stability is strongly correlated with maintaining its activity.

[0403] Conventional pesticide additives are well known in the art and include, but are not limited to, aqueous or organic solvents, buffers, acidifiers, surfactants, wetting agents, spreading agents, tackifiers, fixatives, bases, fillers, thickeners, emulsifiers, dispersants, metal ion chelating agents, anti-settling agents, fusion aids, rheological modifiers, defoamers, photoprotective agents, antifreeze agents, biocides, penetrating agents, mineral or vegetable oils, pigments, and anti-scattering agents, or any suitable combination thereof.

[0404] In yet another embodiment, the present invention provides polypeptides of 80 to 200 amino acids or the subranges disclosed above, which are obtained by affinity selection for a predetermined plant pest target and are capable of inhibiting the growth and / or activity of plant pests at a minimum inhibitory concentration of about 0.00001 to 1 μM.

[0405] In certain embodiments of methods for protecting, preventing, treating or treating plants disclosed herein against fungal infections, the polypeptides or compositions disclosed herein are applied directly or indirectly to the plants by spraying, atomizing, foaming, fogging, hydroponics, coating, immersion, and / or powdering.

[0406] nucleic acid sequence In another embodiment, the present invention provides nucleic acid sequences encoding polypeptide sequences (or suitable fragments thereof) disclosed herein. These nucleic acid sequences may also be in the form of vectors, gene constructs, or polynucleotides. The nucleic acid sequences disclosed herein may be synthetic or semi-synthetic sequences, nucleotide sequences isolated from libraries (particularly expression libraries), nucleotide sequences prepared by PCR using overlapping primers, or nucleotide sequences prepared using DNA synthesis techniques known in themselves.

[0407] The present invention includes nucleic acid sequences encoding any polypeptide disclosed herein. For example, the present invention includes nucleic acid sequences encoding polypeptides comprising an amino acid sequence selected from the group consisting of SEQ ID NOs: 1 to 161, and variants thereof (for example, those having amino acid substitutions or a predetermined percentage of identity with respect to the sequence).

[0408] Construct, vector, host cell The gene construct disclosed herein may be DNA or RNA, but double-stranded DNA is preferred. The gene construct of the present invention may further be in a form suitable for transformation of the target host cell or host organism, in a form suitable for integration into the genomic DNA of the target host cell, or in a form suitable for independent replication, maintenance and / or inheritance in the target host organism. For example, the gene construct of the present invention may be in the form of a vector such as a plasmid, cosmid, YAC, viral vector or transposon. In particular, the vector may be an expression vector, i.e., a vector that enables in vitro and / or in vivo expression (for example, in a suitable host cell, host organism and / or expression system).

[0409] Accordingly, in yet another embodiment, the present invention also provides a vector comprising one or more nucleic acid sequences of the present invention.

[0410] In yet another embodiment, the present invention provides a host or host cell that expresses or is capable of expressing one or more amino acid sequences disclosed herein. Examples of hosts or host cells suitable for expressing the amino acid sequences and polypeptides of the present invention will be obvious to those skilled in the art.

[0411] The present application further discloses that polypeptides of 80 to 200 amino acids or the subranges described above are stably maintained in the pesticide composition or biological control composition as defined in the present application, that is, the integrity of the polypeptides and the pest control activity as defined in the present application are maintained under the storage and / or use conditions of the pesticide composition, such conditions include high temperature, freeze-thaw cycles, changes in pH or ionic strength, UV irradiation, and the presence of harmful chemicals. It is most preferable that these polypeptides of 80 to 200 amino acids are stably maintained in the pesticide composition when the pesticide composition is stored at ambient temperature for two years or when the pesticide composition is stored at 54°C for two weeks. In particular, the polypeptides of 80 to 200 amino acids contained in the pesticide composition maintain at least about 70% of their activity after storage at ambient temperature in the pesticide composition for two years, or when the pesticide composition containing the polypeptides is stored at 54°C for two weeks, and more specifically, maintain at least about 70% to 80% of their activity, and most specifically, maintain about 80% to 90% of their activity.

[0412] In yet another embodiment for use in the methods disclosed herein, the Application discloses a nucleic acid sequence encoding a polypeptide of 80 to 200 amino acids, wherein the polypeptide is obtained by affinity selection for a specific plant pathogenic target, and the polypeptide is capable of inhibiting the growth and / or activity of crop pests at a minimum inhibitory concentration of about 0.00001 to 1 μM.

[0413] We also disclose a chimeric gene comprising the following functionally linked DNA components, namely a) a plant expression promoter, b) a DNA region that, when transcribed, becomes an mRNA molecule capable of being translated into a polypeptide, and c) a 3' terminal region containing a transcription termination and polyadenylation signal that functions within the plant cell.

[0414] A "chimeric gene" or "chimeric construct" is a recombinant nucleic acid sequence in which a promoter (e.g., a plant expression promoter) or regulatory nucleic acid sequence is functionally linked or bound to a nucleic acid sequence encoding mRNA, and when the regulatory nucleic acid sequence is introduced into a cell such as a plant cell, it is configured to regulate the transcription or expression of the bound nucleic acid coding sequence. In nature, the regulatory nucleic acid sequence of a chimeric gene and the nucleic acid sequence to which it is bound in this way are not usually functionally linked.

[0415] In the present invention, the "plant promoter" includes regulatory components that mediate the expression of coding sequence segments in plant cells. To be expressed in plants, nucleic acid molecules must be functionally linked to or contain a suitable promoter that expresses the gene in the required spatial expression pattern at the correct time.

[0416] As used in this application, the term "functionally linked" means that the promoter sequence and the target gene are functionally linked so that the promoter sequence can initiate transcription of the target gene.

[0417] Plant expression promoters contain nucleic acid sequences capable of inducing transgene expression in plants. Examples of plant expression promoters include constitutive promoters that are transcriptionally active under most environmental conditions for most, if not all, of the growth and developmental stages in at least one cell, tissue, or organ; inductive promoters; tissue-specific promoters; and abiotic stress-inducible promoters.

[0418] When a chimeric gene (or expression cassette) is transformed into a plant, it expresses nucleic acids, which in turn express proteins.

[0419] Recombinant vectors containing the expression cassette (or chimeric gene) described above are also disclosed.

[0420] The term "terminator" refers to a regulatory sequence, which is the DNA sequence at the end of a transcription unit that directs the 3' processing and polyadenylation of the primary transcript and the termination of transcription. Terminators can be derived from native genes, various other plant genes, or T-DNA. The terminator to be added can be derived, for example, from the nopalin synthase or octopine synthase gene, or another plant gene, or, less preferably, any other eukaryotic gene.

[0421] A “selection marker,” “selection marker gene,” or “reporter gene” includes any gene that confers a phenotype to cells expressing them, in order to facilitate the identification and / or selection of cells to be transfected or transformed with the nucleic acid construct of the present invention. These marker genes enable confirmation of the successful introduction of nucleic acid molecules by a series of different principles. Appropriate markers may be selected from markers that confer antibiotic or herbicide resistance, markers that introduce novel metabolic traits, or markers that enable visual selection. Examples of selection marker genes include genes that confer antibiotic resistance (e.g., nptll, which phosphorylates neomycin and kanamycin, or hpt, which phosphorylates hygromycin, or genes that confer resistance to bleomycin, streptomycin, tetracycline, chloramphenicol, ampicillin, gentamicin, genethicin (G418), spectinomycin, or blasticidine), genes that confer herbicide resistance (e.g., bar, which provides resistance to Basta(R), aroA or gox, which provides resistance to glyphosate, or genes that confer resistance to imidazolinone, phosphinothricin, or sulfonylurea), or genes that provide metabolic traits (e.g., manA, which enables plants to use mannose as a sole carbon source, or xylose isomerase, which enables the utilization of xylose, or non-nutritional markers such as resistance to 2-deoxyglucose). When a visual marker gene is expressed, it can produce coloration (e.g., β-glucuronidase GUS or β-galactosidase and its coloring agent, e.g., X-Gal), luminescence (e.g., luciferin / luciferase system), or fluorescence (green fluorescent protein GFP and its derivatives). The above examples represent only a small fraction of possible markers. Experienced operators are familiar with such markers. Different markers are preferred depending on the organism and the selection method.

[0422] When nucleic acids are stably or transiently incorporated into plant cells, a small number of these cells are known to take up this foreign DNA and, if necessary, incorporate it into their genome depending on the expression vector and transfection technique used. To identify and select these incorporated cells, genes encoding selection markers (such as those described above) are typically introduced into host cells along with the target gene. These markers can be used, for example, in mutants in which these genes are non-functional due to deletions, for example, by conventional methods. Furthermore, nucleic acid molecules encoding selection markers can be introduced into host cells using the same vector containing the polypeptide of the present invention or the polypeptide sequence used in the method of the present invention, or they can be introduced using a different vector. Cells that have been stably transfected with the introduced nucleic acid can be identified, for example, by selection (e.g., cells that have incorporated the selection marker survive, while cells that have not incorporated it die).

[0423] If nucleic acid introduction is successful, marker genes, particularly those for antibiotic and herbicide resistance, become unnecessary or undesirable in transgenic host cells. Therefore, the nucleic acid introduction method according to the present invention is advantageous when it utilizes a technique that allows for the removal or excision of these marker genes. One example of such a method is called co-transformation. The co-transformation method uses two vectors simultaneously for transformation: a vector carrying the nucleic acid according to the present invention and a second vector carrying the marker gene. A high percentage of transformants (up to 40% or more of transformants) receive both vectors, or in the case of plants, they contain both vectors. In the case of transformation by Agrobacterium, the transformant usually receives only a portion of the vector, i.e., the sequence flanked by T-DNA, which usually corresponds to the expression cassette. Subsequently, the marker gene can be removed from the transformed plant by crossbreeding. In another method, a marker gene incorporated into a transposon is used for transformation along with the desired nucleic acid (called the Ac / Ds technique). Transformants can be crossed with a transposase source, or they can be transformed with a nucleic acid construct that transiently or stably confers transposase expression. In some cases (about 10%), after successful transformation, the transposon is lost, having jumped out of the host cell's genome. More often, the transposon jumps to another location. In these cases, it is necessary to eliminate the marker gene by crossing. Microbiology has developed techniques that enable or facilitate the detection of such events. A more advantageous method relies on a method called a recombinant system, whose advantage is that it eliminates the need for elimination by crossing. The best-known system of this type is called the Cre / lox system. Cre1 is a recombinase that removes sequences located between loxP sequences. If the marker gene is incorporated between loxP sequences, it is removed by the expression of the recombinase after successful transformation.Other recombination systems include the HIN / HIX, FLP / FRT, and REP / STB systems (Tribble et al., J. Biol. Chem., 275, 2000: 22255-22267; Velmurugan et al., J. Cell Biol., 149, 2000: 553-566). The nucleic acid sequence according to the present invention can be incorporated into the plant genome in a site-specific manner.

[0424] For the purposes of the present invention, "transgenic," "transgene," or "recombinant" means, for example, an expression cassette, gene construct, or vector containing the nucleic acid sequence, or an organism transformed with the nucleic acid sequence, expression cassette, or vector according to the present invention.

[0425] Therefore, for the purposes of the present invention, transgenic plants are considered to mean that the nucleic acid used in the method of the present invention is not present in or derived from the genome of the plant, or is present in the genome of the plant but is not present in its natural locus, and the nucleic acid can be expressed in the same species or in different species. However, as stated above, transgenic also means that the nucleic acid according to the present invention or the nucleic acid used in the method of the present invention is in its natural position in the genome of the plant, but its sequence is modified from the natural sequence, and / or the regulatory sequence of the natural sequence is modified. It is preferable to consider transgenic as meaning that the expression of the nucleic acid according to the present invention occurs at a non-natural locus in the genome, that is, that the nucleic acid is expressed in the same species or in different species. Preferred transgenic plants are referred to in this application.

[0426] The terms "expression" or "gene expression" mean the transcription of one or more specific genes or gene constructs. Specifically, "expression" or "gene expression" means that one or more genes or gene constructs are transcribed into structural RNA (rRNA, tRNA) or mRNA, which may or may not be translated into protein. This process includes the transcription of DNA and the processing of the resulting mRNA product.

[0427] As used in this application, the terms “increased expression” or “overexpression” refer to any form of expression added to the original wild-type expression level. For the purposes of this invention, the original wild-type expression level may be zero, i.e., expression may be absent, or expression may be unmeasurable.

[0428] Methods for increasing the expression of a gene or gene product are clearly described in the literature in the art, and include, for example, overexpression driven by a suitable promoter (as described above), the use of a transcriptional enhancer, or a translational enhancer. Isolated nucleic acids that function as promoter or enhancer elements can be introduced at a suitable position (generally upstream) of a non-heterogeneous polynucleotide to upregulate the expression of the nucleic acid encoding the polypeptide of interest. When polypeptide expression is desired, it is generally desirable to add a polyadenylated region to the 3' end of the polynucleotide coding region. The polyadenylated region can be derived from a native gene, various other plant genes, or T-DNA. The 3' end sequence to be added can be derived, for example, from a nopalin synthase or octopine synthase gene, or another plant gene, or, less preferably, any other eukaryotic gene.

[0429] To increase the amount of maturation messages accumulated in the cytosol, intron sequences may be added to the 5' untranslated region (UTR) of a partial coding sequence or to the coding sequence itself. Adding splicable introns to transcription units in both plant and animal expression constructs has been shown to increase gene expression by up to 1000-fold at both the mRNA and protein levels (Buchman and Berg (1988) Mol. Cell biol. 8:4395-4405; Callis et al. (1987) Genes Dev 1:1 183-1200). Such intron enhancement of gene expression is generally maximized when the introns are located near the 5' end of the transcription unit. The use of maize introns Adh1-S introns 1, 2, and 6, and the Bronze-1 intron is known in the art. For general information, see The Maize Handbook, Chapter 1 16, Freeling and Walbot, Eds., Springer, NY (1994).

[0430] As used herein, the terms “introduction” or “transformation” refer to the introduction of an exogenous polynucleotide or chimeric gene (or expression cassette) into host cells, regardless of the method used for introduction. Plant tissues capable of subsequent clonal propagation, whether by organogenesis or embryogenesis, can be transformed with the gene constructs of the present invention, resulting in the regeneration of a complete plant. The specific tissues selected depend on the available and optimal clonal propagation system for the specific species to be transformed. Typical tissue targets include leaf discs, pollen, embryos, cotyledons, hypocotyls, megagametophytes, callus tissue, existing meristems (e.g., apical meristem, axillary buds, and root meristems), and induced meristems (e.g., cotyledonous meristems and hypocotyl meristems). Polynucleotides can be introduced into host cells transiently or stably, and may remain unintegrated, for example, as a plasmid. Alternatively, they may be integrated into the host genome. The resulting transformed plant cells can then be used to regenerate transformed plants in methods known to those skilled in the art.

[0431] The process of introducing foreign genes into the genome of a plant is called transformation. Plant transformation is now a fairly common technique. It has the advantage that any of several transformation methods can be used to introduce the target gene into the appropriate ancestral cells. Methods described for the transformation and regeneration of plants from plant tissue or plant cells can be used for transient or stable transformation. Transformation methods include the use of liposomes, electroporation, chemicals that enhance free DNA uptake, direct injection of DNA into plants, particle gun methods, transformation methods using viruses or pollen, and microinjection methods. Methods such as the calcium / polyethylene glycol method for protoplasts (Krens, FA et al., (1982) Nature 296, 72-74; Negrutiu I et al. (1987) Plant Mol Biol 8:363-373); electroporation of protoplasts (Shillito RD et al. (1985) Bio / Technol 3, 1099-1 102); microinjection into plant material (Crossway A et al., (1986) Mol. Gen Genet 202:179-185); particle gun method using DNA or RNA-coated particles (Klein TM et al., (1987) Nature 327:70); and infection with (non-integrated) viruses can be selected. Transgenic plants, including transgenic cultivated plants, are preferably produced by transformation using Agrobacterium. The advantageous transformation method is transformation in the plant body. For this purpose, for example, Agrobacterium can be applied to plant seeds or inoculated into plant meristems. According to the present invention, it has been found to be particularly advantageous to apply a suspension of transformed Agrobacterium to intact plants or at least to the primordia. The plants are then grown until seeds of the treated plants are obtained (Clough and Bent, Plant J. (1998) 16, 735-743).Well-known rice transformation methods using Agrobacterium include those described in the following documents, namely, European Patent Application EP1198985, Aldemita and Hodges (Planta 199:612-617, 1996), Chan et al. (Plant Mol Biol 22(3):491-506, 1993), and Hiei et al. (Plant J 6(2):271-282, 1994), and the entire disclosure thereof is incorporated into this application. In the case of maize transformation, preferred methods are those described in either Ishida et al. (Nat. Biotechnol 14(6):745-50, 1996) or Frame et al. (Plant Physiol 129(1):13-22, 2002), and the entire disclosure thereof is incorporated into this application. The aforementioned method is also described, for example, in B. Jenes et al., Techniques for Gene Transfer, in: Transgenic Plants, Vol. 1, Engineering and Utilization, eds. SDKung and R. Wu, Academic Press (1993) 128-143, and Potrykus Annu. Rev. Plant Physiol. Plant Molec. Biol. 42 (1991) 205-225). It is preferable to clone the nucleic acid or construct to be expressed into a vector suitable for transforming Agrobacterium tumefaciens (e.g., pBin19) (Bevan et al (1984) Nucl. Acids Res. 12-8711).Subsequently, Agrobacterium transformed with such vectors can be used for plant transformation in known methods. For example, by immersing crushed or shredded leaves in an Agrobacterium solution and then culturing them in a suitable medium, it can be used in plants used as models, such as Arabidopsis (Arabidopsis thaliana is not considered a cultivated plant within the scope of this invention), or in cultivated plants such as tobacco. The method of plant transformation using Agrobacterium tumefaciens is known, for example, from Hofgen and Willmitzer in Nucl. Acid Res. (1988) 16, 9877, or in particular from FF White, Vectors for Gene Transfer in Higher Plants; in Transgenic Plants, Vol. 1, Engineering and Utilization, eds. SDKung and R. Wu, Academic Press, 1993, pp. 15-38.

[0432] In addition to the transformation of somatic cells that need to be regenerated into intact plants later, it is also possible to transform cells of plant meristems, particularly cells that will grow into gametes. In this case, the transformed gametes will undergo natural plant development, producing transgenic plants. For example, Arabidopsis seeds can be treated with Agrobacterium, and seeds can be obtained from developing plants in which a predetermined proportion have been transformed into transgenic plants [Feldman, KA and Marks MD (1987). Mol Gen Genet 208:1-9; Feldmann K (1992). In: C Koncz, NH Chua and J Shell, eds, Methods in Arabidopsis Research. Word Scientific, Singapore, pp.274-289]. Another method involves repeatedly removing the inflorescence and incubating the excised central rosette with transformed Agrobacterium to obtain similarly transformed seeds at a later stage (Chang (1994). Plant J. 5:551-558; Katavic (1994). Mol Gen Genet, 245:363-370). However, particularly effective methods are the vacuum immersion method and its variations, such as the "floral dip" method. In the vacuum immersion method for Arabidopsis, intact plants are treated with an Agrobacterium suspension under reduced pressure [Bechthold, N (1993). CR Acad Sci Paris Life Sci, 316: 1 194-1 199], while in the "floral dip" method, developing floral tissue is briefly incubated with an Agrobacterium suspension treated with a surfactant [Clough, SJ and Bent AF (1998) The Plant J. 16, 735-743]. In both cases, a predetermined proportion of transgenic seeds are harvested, and these seeds can be distinguished from non-transgenic seeds by growing them under the selection conditions described above. Furthermore, stable transformation of plastids is advantageous because plastids are maternally inherited in most crops, and the risk of transgene leakage via pollen is reduced or eliminated.Chloroplast genome transformation is generally performed by the method schematically shown in Klaus et al., 2004 [Nature Biotechnology 22(2), 225-229]. In summary, the sequence to be transformed is cloned along with a selection marker gene between homologous flanking sequences of the chloroplast genome. These homologous flanking sequences induce site-specific integration into the chloroplast genome (plastome). Plastiid transformation methods have been described for a wide variety of plant species, and reviews are available in Bock (2001) Transgenic plastids in basic research and plant biotechnology. J Mol Biol. 2001 Sep 21;312(3):425-38 or Maliga, P (2003) Progress towards commercialization of plastid transformation technology. Trends Biotechnol. 21, 20-28. Furthermore, recent biotechnological advances have been reported in the production of marker-free plastid transformants that can be produced by transiently and simultaneously incorporated marker genes (Klaus et al., 2004, Nature Biotechnology 22(2), 225-229).

[0433] Genetically modified plant cells can be regenerated using all methods familiar to skilled operators. For appropriate methods, please refer to the publications by SDKung and R. Wu, Potrykus or Hofgen and Willmitzer mentioned above.

[0434] Generally, after transformation, plant cells or cell groups are selected for the presence of one or more markers encoded by plant-expression genes transfected with the target gene, and then the transformed material is regenerated into a complete plant. To select transformed plants, the plant material obtained by transformation is generally subjected to selection conditions so that transformed plants can be distinguished from non-transformed plants. For example, the seeds obtained as described above can be sown and subjected to appropriate selection by spraying after the initial growth period. Alternatively, the seeds may be grown on agar plates using an appropriate selective agent after sterilization as needed, so that only transformed seeds can grow into plants. Or, transformed plants can be screened for the presence of selection markers such as those described above.

[0435] After DNA introduction and regeneration, the plants presumed to be transformed may be evaluated for the presence, copy number, and / or genome composition of the target gene, for example, using Southern blot analysis. Alternatively, or in addition to this, the expression level of the newly introduced DNA may be monitored by Northern blot analysis and / or Western blot analysis, both of which are well known to those with ordinary skill in the art.

[0436] The transformed plants can be propagated by various means, such as clonal propagation and classical breeding techniques. For example, first-generation (or T1) transformed plants can be self-fertilized, homozygous second-generation (or T2) transformed plants can be selected, and then the T2 plants can be further propagated using classical breeding techniques. The transformed organisms can take various forms. For example, they can be chimeras of transformed and untransformed cells, clonal transformeds (e.g., whole cells transformed to include an expression cassette), or grafts of transformed and untransformed tissues (e.g., in plants, a transformed rootstock is grafted onto an untransformed scion).

[0437] The present invention will be specifically described below with reference to non-limiting embodiments. [Examples]

[0438] [Example 1] Preparation of Fusarium oxysporum Folch-phase antigen for immunotherapy, phage display, and screening assays Intact hyphae and conidia of Fusarium oxysporum were sequentially extracted at room temperature using chloroform:methanol in 2:1 and 1:2 (v / v) ratios. The extracts were combined, dried, and the crude lipid extract was partitioned as described by Folch et al. (1957. A simple method for the isolation and purification of total lipids from animal tissues. J. Biol. Chem. 226, 497-509.). Lipids derived from the lower layer of the Folch method were recovered and used for immunization.

[0439] [Example 2] Preparation of ceramide monohexoside fraction of Fusarium oxysporum for phage display and screening assays Ceramide monohexoside fractions derived from Fusarium oxysporum, prepared according to the method described by Barreto-Bergter et al. (2011 Barreto-Bergter E, Sassaki G and, de Souza LM. (2011) Structural analysis of fungal cerebrosides. Front Microbiol. 2:239.), were obtained from Eliana Barreto-Bergter.

[0440] [Example 3] Identification of VHH binding to the lower-phase antigen of Fusarium oxysporum using the Forti method. 3.1 Immunology VHH was prepared from llamas immunized with a Fusarium oxysporum-derived Folzhi subphase extract. Following a standard protocol, llamas were boost-immunized six times with a Folzhi subphase extract spotted on thin-layer chromatography (TLC). Silica adsorbed with the Folzhi subphase extract was scraped from the plate and suspended in phosphate buffer. The suspension was sonicated, mixed with incomplete Freund's adjuvant, and used for subcutaneous injection. All llamas remained healthy throughout the immunization process, and blood samples were collected before and after immunization.

[0441] 3.2 Library Construction For library construction, peripheral blood mononuclear cells were prepared from immunized llama blood samples using Ficoll-Hypaque according to the manufacturer's instructions. Total RNA was extracted from these cells and used as a starting material for RT-PCR to amplify VHH encoding gene fragments. These fragments were cloned into the phagemide vector pASF20. pASF20 is an expression vector derived from pUC119 and contains the lacZ promoter, synthetic leader sequence, multicloning site, colyphage pIII protein coding sequence, ampicillin resistance gene, and M13 phage origin for single-strand production. This vector encodes the C-terminal (His)6 peptide tag and c-myc peptide tag in frame with the VHH coding sequence. Phages were constructed according to standard methods (Phage Display of Peptides and Proteins: A Laboratory Manual; Brian K. Kay, Jill Winter, Dr. John McCafferty). Libraries with clonal diversity of 1E+08 or higher were obtained, confirming phage production and antibody diversity.

[0442] 3.3 Selection Two rounds of panning selection were performed as follows. The fungal lipid fraction was coated onto polystyrene Maxisorp multiwell plates using 5% chloroform / methanol as the solvent in both rounds. In the first round of selection, 25 μl of phages (1,000E+11 phages / selection condition) were selected from the library using four different conditions: two different lipid fraction (fungal; Fusarium oxysporum) concentrations (50 μg / ml and 5 μg / ml) and two different blank conditions for background control (5% CHCl3 / MeOH and PBS). In the second round of selection, in addition to the conditions of the first round, an even lower antigen concentration (0.5 μg / ml) was used. In the second round of selection, the phage input was diluted 10-fold compared to the input from the first round of selection to reduce the selection of non-specific phage binding.

[0443] In the first round of selection, good enrichment was observed, particularly from the 50 μg / ml selection condition. The phage output from this selection was rescued, precipitated, and used as input in the second round of selection. In this selection round, significantly higher enrichment was observed under the antigen-coated conditions, with the exception of the 0.5 μg / ml selection condition.

[0444] After the second round of panning selection, the selected eluted phage pool was used to infect E. coli TG1 cells. Individual colonies were picked and transferred to a 96-well plate containing 100 μl each of 2×TY medium supplemented with 2% glucose and 100 μg / ml carbenicillin to create a master plate (MP). The cells were grown overnight at 37°C. The master plate was stored in 20% glycerol at -80°C and used for periplasm extract production, screening, and sequencing.

[0445] [Example 4] Screening of VHHs that bind to the lipid fraction of Fusarium oxysporum To verify whether VHH binds to the lipid fraction of Fusarium oxysporum, binding was evaluated by ELISA. Each clone was screened for binding to wells coated with 10 μg / ml of fungal lipid fraction dissolved in 5% CHCl3 / MeOH, and to wells coated with 5% CHCl3 / MeOH alone. A clone was considered positive if the ratio of the OD450nm binding signal in the antigen-coated well to the corresponding blank well was greater than 2. An overall hit rate of 14.2% was obtained using the standard cutoff criteria applied to the 360 ​​individual clones tested.

[0446] [Example 5] VHH10G11 dose-dependently inhibits the growth of Botrytis cinerea in an in vitro antifungal assay.

[0447] The antifungal activity of VHH10G11Q (SEQ ID NO: 1) against the plant pathogenic fungus Botrytis cinerea R16 was evaluated in vitro.

[0448] A 2-fold dilution of purified VHH10G11Q was prepared in a 96-well microtiter plate. Starting with a final VHH10G11Q concentration of 10 μM, 20 μl of these dilutions and 20 μl of water as a control were mixed with 80 μl of fungal spore suspension (1E+05 spores per 1 ml of 1 / 2 concentration potato modextrose broth (PDB)). The test plates were incubated at 25°C for 36 hours using the IncuCyte Zoom live cell imaging system. At least two plates were used for each test.

[0449] As shown in Figure 1, the results of the antifungal activity assay revealed a clear dose-dependent growth inhibition pattern when expressed as % fungal growth (total area of ​​green objects) relative to the VHH10G11Q concentration (μM).

[0450] [Example 6] VHH10G11 more strongly inhibits the growth of Botrytis cinerea compared to glycosylceramide-binding VHH41D01 in an in vitro antifungal assay.

[0451] WO2014 / 177595A1 and WO2014 / 191146A1 describe several anti-glucosylceramide-binding VHHs, of which VHH41D01 shows the most significant antifungal activity among several test strains, including Botrytis cinerea R16.

[0452] The growth inhibitory properties of VHH10G11Q (SEQ ID NO: 1) against the plant pathogenic fungus Botrytis cinerea R16 were compared in vitro with those of VHH41D01.

[0453] Purified VHH10G11Q and 41D01 were prepared in 2-fold dilutions in 96-well microtiter plates. Starting with a final VHH10G11Q concentration of 40 μM, 20 μl of these dilutions and 20 μl of water as a control were mixed with 80 μl of fungal spore suspension (1E+05 spores per 1 ml of 1 / 2 concentration potato modextrose broth (PDB)). The test plates were incubated at 25°C for 48 hours using the IncuCyte Zoom live cell imaging system. At least two plates were used for each test.

[0454] Surprisingly, the results of the antifungal activity assay shown in Figure 2 revealed a more pronounced growth inhibition pattern in VHH10G11Q compared to the biologically active VHH41D01.

[0455] [Example 7] Site-directed mutagenesis Site-directed mutagenesis of VHH was performed as follows. The nucleotide sequence encoding the VHH sequence mutant was synthesized as a gene fragment and then cloned into the plasmid pPpT4GAPαS (Naatsaari et al (2012), Plos One, 7(6):e39720), which is suitable for transformation of Pichia pastoris (Pichia yeast). This plasmid was then used to induce expression from the cloned gene fragment. AOXThe promoter was included. Standard cloning techniques were used to construct the plasmid containing the target VHH sequence variant. The successfully generated clones were sequenced to confirm the presence of the target VHH sequence variant and that they were correctly cloned. Subsequently, the linearized plasmid was transformed into competent Pichia pastoris (Pichia yeast) ATCC76273(TM) cells using a standard electroporation protocol. Then, the successfully generated transformants were used to produce the VHH sequence variant. First, the transformants were cultured in BMGY (buffered glycerol complex medium), then transferred to BMMY (buffered methanol complex medium) to initiate induction (Weidner et al (2020), J Vis Exp, 36:1862). Subsequently, VHH was purified using filtration and / or chromatography techniques widely known in the art.

[0456] [Example 8] Ala scanning of VHH10G11 All three CDR regions of VHH10G11 were evaluated by Ala scanning to investigate the effect of single-amino acid substitutions on the antifungal activity of VHH10G11 (SEQ ID NOs: 18-51). After constructing and preparing mutants of 10G11 as described in Example 7, antifungal assays were performed as described in Example 5. Surprisingly, as clearly demonstrated by the maintenance of antifungal activity in the mutants, 10G11 maintained its performance in most mutants in which individual amino acids in the CDR region were substituted with alanine (Figure 3). Similar results were obtained when other single-amino acid substitution mutants were constructed using glycine (R26G; SEQ ID NO: 18 and D35G; SEQ ID NO: 27), serine (R53S; SEQ ID NO: 32 and T56S; SEQ ID NO: 36), or asparagine (K58N; SEQ ID NO: 39) instead of alanine (Figure 3).

[0457] [Example 9] Improvement of antifungal activity of VHH10G11 with His tag attached The His tag is commonly added to polypeptides for purification using affinity chromatography. Surprisingly, during routine testing using an antifungal assay as described in Example 5, the 10G11Q polypeptide (SEQ ID NO: 148) with a 6×His tag added to its C-terminus showed significantly improved antifungal activity (Figure 4). Since the His tag consists of six positively charged histidine amino acids, it was thought that the positive charge was beneficial for the antifungal interaction of 10G11.

[0458] [Example 10] In silico modeling of VHH10G11Q To better understand the 10G11 molecule, its three-dimensional structure was modeled using an in silico approach. A BLAST search was performed in the Protein Data Bank (PDB) to obtain the structural coordinates of antibodies with the same CDR length as the 10G11 molecule to be modeled. A Blosum 62 matrix was used with a gab cost of 13. Of the top 250 hits, each structure with the same CDR length as the target 10G11 molecule was used for homology modeling trials. First, residues that differed between the obtained PDB structure and the 10G11 molecule were mutated. Next, the side chains of these residues were modeled according to their experimental priority, as detected in the Dunbrack 2010 rotational isomer library (Shapovalov and Dunbrack, (2011), Structure, 19(6):844-58). Where necessary, the immediate side chain was also modeled to adopt the modeling mutation. Using this model as a guide, the important amino acid residues of the molecule were determined.

[0459] The resulting model is shown in Figure 5, along with the display of three CDR regions. The selection of exposed side chains is visualized on the 10G11 ribbon diagram and displayed according to Kabat numbering (Figure 5 also shows the germline sequence and the substitutions that result in the 10G11 sequence. Furthermore, the corresponding Kabat numbering is also shown). Since the side chains were exposed and structural damage appeared to be minimal, these amino acid residues were selected as the best candidates for specific amino acid substitutions.

[0460] [Example 11] Antifungal activity of the 10G11 charge mutant As confirmed by the assay results shown in Figure 3, four of the five mutants that showed decreased antifungal activity were characterized by the substitution of a positively charged amino acid with an uncharged mutant. Considering the result that the positively charged His-tagged mutant showed increased antifungal activity (Figure 4), the effect of charge was further investigated. For this purpose, various 10G11 charge mutants were prepared as described in Example 7, and their antifungal activity was tested as described in Example 5. The following substitutions were designed to reduce the total charge of the 10G11 molecule at the antigen-binding interface. • Mutant 1: R26A substitution in CDR1 (SEQ ID NO: 7) • Mutant 2: R53A and K58A substitutions in CDR2 (SEQ ID NO: 8) • Mutant 3: R96A and R10...
