The present invention further relates to plant cells and plants that have been modified to achieve regulation of alkaloid content. The present invention also relates to processed and harvested leaves from such regulated plants and their use in tobacco industry products, including combustible smoking products.
[0002] background
[0003] Alkaloids are a group of naturally occurring compounds that contain primarily basic nitrogen atoms and are produced by a wide variety of organisms including bacteria, fungi, plants, and animals.
[0004] Alkaloids can be classified based on similarities in their carbon skeletons, such as indole, isoquinoline, and pyridine. Pyridine derivatives are a class of monomeric alkaloids; this category includes simple pyridine derivatives, polycyclic condensed and non-condensed pyridine derivatives, and sesquiterpene pyridine derivatives. Examples include nicotine, nornicotine, anabasine, mithosamine, and anatabine.
[0005] Most of the known biological functions of alkaloids are related to protection. Neuroactive molecules such as caffeine, cocaine, morphine, and nicotine act as defense compounds against invading predators. The accumulation of these alkaloids is the result of signal transduction cascades that monitor gene expression, enzyme activity, and alkaloid concentration. The fine regulation of alkaloid content in plants involves negative feedback loops and degradation pathways.
[0006] Nicotine occurs naturally in several plant species, but is found at its highest levels in tobacco plants. Cultivated tobacco produces 2-4% of the alkaloid by weight. Nicotine is present in both wild and cultivated Nicotiana species ( Nicotiana ) species and plays an important role in plant defense against herbivores and insects (Voelckel et al. (2001) Oecologia 127(2): 274-280, incorporated herein by reference). It accounts for ~90% of the total alkaloid content. The remaining 10% of the alkaloid pool is mainly composed of the structurally related compounds nornicotine, anatabine, anabasine, and pseudooxynicotine (PON).
[0007] The regulation of alkaloid content in tobacco is complex. Several factors, including genotype, environment, fertilization, and agronomic practices (e.g., topping), affect alkaloid levels in tobacco plants. Some key regulators of nicotine biosynthesis are well characterized, such as putrescine N-methyltransferase (PMT), which plays a key role in this pathway, is activated by members of the ethylene response factor (ERF) superfamily, the largest family of transcription factors in the tobacco genome (Rushton et al. (2008) Plant Physiol. 147(1): 280-295, incorporated herein by reference). Other transcription factors that induce alkaloid biosynthesis belong to the MYC2-like basic helix-loop-helix (bHLH) family. MYC2-like bHLHs directly regulate alkaloid levels through the binding and activation of Gbox-mediated alkaloid structural genes, and indirectly regulate alkaloid levels through the activation of ERFs.
[0008] The alkaloid content in the modification plant (for example tobacco) can have several commercial advantages.For example, reducing the total alkaloid content in the plant can increase the value of the plant as a biomass resource.For example, modifying the alkaloid content can comprise reducing the alkaloid content in the tobacco plant, for example nicotine content. In view of " nicotine ceiling (nicotineceiling) ", i.e. the potential regulation of the average nicotine upper limit in the tobacco product, the tobacco plant and the product with the nicotine reduced may be desired. Or, increase the alkaloid content in the plant for example tobacco plant, can help protect plants with anti-insect and herbivorous animals. Still need plant and preparation method thereof, the plant has the alkaloid content of regulation when there is the proterties expected commercially of improvement, for example, has the nicotine content of regulation.
[0009] During post-harvest leaf conditioning, reactions between pyridine alkaloids and nitrosating substances lead to the formation of tobacco-specific nitrosamines (TSNAs). Nornicotine and PON are precursors of the TSNAs NNN and NNK, respectively. Reducing the production and accumulation of nornicotine and PON is crucial. The CYP82E family of nicotine demethylase genes is one of the main regulators of the conversion of nicotine to nornicotine, and altering their activity or accumulation could lead to reduced NNN levels. However, to date, the enzyme or gene responsible for PON production has not been identified.
[0010] As described in the examples, the inventors sought to investigate the genes responsible for alkaloid synthesis with the aim of modulating the alkaloid content in plants, for example reducing the nicotine content in tobacco plants. SUMMARY OF THE INVENTION
[0012] Surprisingly, it has been discovered that by modulating the activity or expression of a gene encoding a SOUL heme-binding protein, the alkaloid content and / or TSNA content or TSNA precursor content of a plant can be modulated. A SOUL heme-binding protein, such as Nitab4.5_0013616g0010.2, as taught herein, is a regulator of nicotine, nornicotine, anabasine, PON, miosamine, and anatabine in cultivated tobacco. Nitab4.5_0013616g0010.2 encodes a SOUL heme-binding protein according to the present invention. Nitab4.5_0000652g0130.2, Nitab4.5_0001140g0220.2, Nitab4.5_0003235g0060.2, Nitab4.5_0004868g0020.2, Nitab4.5_0006614g0010.2, Nitab4.5_0006991g0050.2 and Nitab4.5_0009023g0010.2 encode homologues of Nitab4.5_0013616g0010.2 according to the present invention. The SOUL heme-binding protein according to the present invention contains a conserved three-dimensional structure called the SOUL motif. The SOUL heme-binding protein according to the present invention binds heme.
[0013] According to the present invention, tobacco products having regulated alkaloid content and commercially desirable traits sought after by consumers of tobacco products can be produced. In some cases, consumers may desire products with low levels of alkaloid content, such as low levels of TSNA or low nicotine content.
[0014] The present invention may be particularly useful in the field of plant molecular farming, where plants (such as tobacco and other Nicotiana species) are used to produce proteins, peptides and metabolites, for example for the production of therapeutics and drugs such as antibiotics, virus-like particles, or neutraceuticals or small molecules. In an EU-funded project called PharmPlant, tobacco has been used to develop HIV-neutralizing antibodies, and Medicago Inc. in Canada has participated in a tobacco-based platform for the production of virus-like particles for influenza vaccine manufacturing.
[0015] Thus, plants according to the present invention can be used in molecular farming to reduce or eliminate the presence of nicotine, nornicotine, PON and / or other nicotine alkaloids, such as anabasine or anatabine or mithosamine. The use of low-nicotine plants or roots is beneficial in molecular farming and will reduce downstream processing costs associated with purification.
[0016] In other cases, it may be desirable to produce plants with high alkaloid levels, such as high levels of nicotine content, so that nicotine can be purified from tobacco plants to produce pure nicotine products, such as for use in devices that utilize nicotine-containing liquids (e.g., e-cigarettes) or tobacco heating devices. For example, the production of plants with leaves containing high levels of nicotine can reduce the cost of nicotine extraction for the production of e-liquids for e-cigarettes.

DRAWINGS
[0078] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
[0079] I don't want to be bound by theory. Figure 1 Depicted are the effects of overexpressing the SOUL heme-binding protein on pyridine alkaloid biosynthesis. (A) Upon sensing wounds or herbivory, surface-localized receptors induce immune signaling via phosphorylation of MAPKs and the production of reactive oxygen species (ROS). This activates jasmonic acid (JA)-responsive genes and upregulates pyridine alkaloid production. Intracellular ROS levels are tightly regulated through heme oxygenase (HO)-mediated heme catabolism. (B) SOUL overexpression reduces the available heme for HO degradation. This leads to an increase in intracellular ROS, which upregulates the nicotine biosynthesis pathway. PM: plasma membrane.

[0144] Details
[0145] The present inventors have shown for the first time that by modulating the activity or expression of at least one gene encoding a SOUL heme-binding protein in a plant (eg a tobacco plant), the alkaloid and / or TSNA content of the plant (or processed plant) can be modulated.

A comparable product according to the present invention may mean a plant (e.g., a tobacco plant) or part thereof, such as leaves (e.g., tobacco leaves), harvested leaves (e.g., harvested tobacco leaves), cut harvested leaves (e.g., cut harvested tobacco leaves), processed leaves (e.g., processed tobacco leaves), or plant propagation material (e.g., tobacco plant propagation material), or a product, such as a tobacco product, or a combination thereof, comprising said plant or part thereof.

[0166] As used herein, the term "modification" or "modified" refers to a plant (e.g., a tobacco plant) or nucleic acid sequence that has been altered or changed. The present invention encompasses plant modifications using techniques for genetic modification of plants or non-genetic modification of plants.

[0168] SOUL heme-binding protein
[0169] As used herein, "SOUL heme-binding protein" has its ordinary meaning in the art and refers to a protein comprising a SOUL motif, which is a hydrophobic cleft flanked by α-helices and β-loops.
[0170] SOUL heme-binding proteins are found in bacteria, plants, and animals. SOUL heme-binding proteins bind tetrapyrroles such as heme (Takahashi et al. (2008) Photochem. Photobiol. Sci. 7, 1216-1224). It has been proposed that SOUL proteins in plants may be involved in transporting heme to other heme-containing proteins such as cytochrome P450 and in binding free heme (Freire et al. (2009) Acta Cryst. F65, 723-726).
[0171] The three-dimensional structure of the mouse SOUL heme-binding protein has been determined. The mouse SOUL structure consists of nine twisted β-barrels, two α-helices, and a hydrophobic cleft. The hydrophobic cleft is flanked by one of the α-helices and the β8-9 loop, forming a conserved "SOUL motif," which is crucial for heme binding (Dias et al. (2006) J. Biol. Chem. 276, 18161-18168). A similar structure has been predicted for the Arabidopsis SOUL heme-binding protein (Takahashi et al. (2008) Photochem. Photobiol. Sci. 7, 1216-1224).
[0172] In one embodiment, the SOUL heme-binding protein comprises a SOUL motif. As used herein, the term "SOUL motif" refers to a conserved structural motif. SOUL heme-binding protein and the SOUL motif can be identified by comparing the predicted protein structure to known protein structures. For example, the SOUL heme-binding protein and the SOUL motif can be identified by comparing the predicted protein structure to the predicted structure of SEQ ID No. 1, wherein the presence of a hydrophobic cleft flanked by α-helices and β-loops identifies the protein as a SOUL heme-binding protein.
[0173] In one embodiment, the SOUL motif is a region of the protein corresponding to a hydrophobic cleft flanked by α-helices and β-loops.The SOUL motif may be involved in heme-binding.
[0174] Without wishing to be bound by theory, it is hypothesized that increasing the content of SOUL heme-binding protein in plant cells or increasing the activity of SOUL heme-binding protein in plants, such as heme-binding activity, will result in an increase in the binding of free heme. A reduction in the level of free heme will mean a reduction in the degradation of heme by heme oxygenase, resulting in a reduction in the removal of reactive oxygen species (ROS). ROS stimulates the activation of nicotine biosynthesis genes. An increase in the activity or expression of SOUL heme-binding protein thus results in an increase in pyridine alkaloid levels. Conversely, according to this hypothesis, a reduction in the level or activity (such as heme-binding activity) of SOUL heme-binding protein in plant cells will increase the amount of free heme, resulting in an increase in ROS removal, and therefore reducing the activation of nicotine biosynthesis genes, thereby reducing the level of pyridine alkaloids in the cell. This hypothesis is graphically depicted in Figure 1 middle.

[0215] As used herein, the term "increase" or "enhance" (e.g., increase the activity or expression of a gene encoding a SOUL heme-binding repeat protein) means that the activity or expression of a gene encoding a SOUL heme-binding repeat protein is higher or increased compared to the activity or expression of the gene in a comparable product.
[0216] According to the present invention, the activity or expression of the gene encoding the SOUL heme-binding protein is modulated.
[0217] In one aspect, the present invention provides a method for modulating (i.e., increasing or decreasing) the alkaloid content of a plant or a part or cell thereof (e.g., a plant cell), the method comprising modifying the plant by modulating (i.e., increasing or decreasing) the activity of at least one gene encoding a SOUL heme-binding protein.
[0218] The term "activity" refers to any function of the SOUL heme-binding protein encoded by at least one gene. Examples of activity include enzymatic activity or localization of the SOUL heme-binding protein. Suitably, the activity is the ability of the SOUL heme-binding protein to interact with another molecule or molecules. In some embodiments, the present invention provides a method of modulating (i.e., increasing or decreasing) the alkaloid content of a plant or part or cell thereof (e.g., a plant cell), the method comprising modifying the plant by modulating (i.e., increasing or decreasing) the ability of the SOUL heme-binding protein to interact with another molecule.
[0219] Suitably, the ability of the SOUL heme-binding protein to interact with other molecules is the ability to bind to other molecules. The other molecules may be proteins. The other molecules may be tetrapyrroles. The other molecules may be heme. In some embodiments, the present invention provides methods for modulating (i.e., increasing or decreasing) the alkaloid content of a plant or part or cell thereof (e.g., a plant cell), the methods comprising modifying the plant by modulating (i.e., increasing or decreasing) the ability of the SOUL heme-binding protein to bind heme.
[0220] Suitably, the other molecules are more than one molecule, such as one or more molecules, such as two or more molecules, such as three or more molecules. In the case where the other molecules are more than one molecule, the other molecules may be the same molecule or may be different molecules. In the case where the other molecules are more than one molecule, at least one of the other molecules may be heme.
[0221] Modulation of the activity of a gene encoding a SOUL heme-binding protein may entail increasing or decreasing the activity of the SOUL heme-binding protein.
[0222] Increasing the activity of a SOUL heme-binding protein refers to enhancing or improving the ability of the SOUL heme-binding protein to carry out a specific function compared to the SOUL heme-binding protein in a plant that has not been modified according to the present invention.
[0223] Reducing the activity of a SOUL heme-binding protein means reducing, inhibiting or disrupting the ability of the SOUL heme-binding protein to perform a specific function compared to the SOUL heme-binding protein in a plant that has not been modified according to the present invention. The activity of the SOUL heme-binding protein can be reduced to such an extent that the activity is prevented or eliminated.
[0224] In some embodiments, the activity of the SOUL heme-binding protein may be modulated (i.e., increased or decreased) by at least about 10%, 20%, 30% or 40%, suitably at least about 50%, 60%, 70%, more suitably at least about 80%, 90%, 95% or 100% compared to the activity of a gene encoding the SOUL heme-binding protein in a plant (e.g., a tobacco plant) not modified according to the invention.
[0225] In some embodiments, the modulated SOUL heme-binding protein exhibits an increased or decreased activity compared to unmodified SOUL heme-binding protein. The modulated SOUL heme-binding protein can exhibit an activity that is increased or decreased by at least about 1%, at least about 3%, at least about 5%, at least about 10%, at least about 20%, at least about 30%, at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, or at least about 90% compared to unmodified SOUL heme-binding protein.
[0226] Suitably, modulation of activity is an increase or decrease in the ability of the SOUL heme-binding protein to interact with (such as bind to) another molecule or molecules (such as heme).
[0227] In some embodiments, the present invention provides a method for regulating the alkaloid content of a plant, or a part or cell thereof, the method comprising modifying the plant by modulating the ability of a SOUL heme-binding protein to bind heme. Suitably, the ability of a SOUL heme-binding protein to bind heme is increased. Suitably, the ability of a SOUL heme-binding protein to bind heme is decreased. An increase or decrease in the ability of a SOUL heme-binding protein to bind another molecule can be expressed as an increase or decrease in the binding affinity of the SOUL heme-binding protein. In some embodiments, the present invention provides a method for regulating the alkaloid content of a plant, or a part or cell thereof, the method comprising modifying the plant by modulating the binding affinity of a SOUL heme-binding protein for heme.
[0228] Techniques for measuring protein activity are known in the art. For example, assays for measuring the enzymatic activity of proteins are known, and microscopy techniques can be used to identify the localization of proteins.
[0229] Specifically, the ability of a SOUL heme-binding protein to bind to another molecule can be measured using techniques known in the art. Examples of such techniques include immunoprecipitation, isothermal calorimetry, surface plasmon resonance, and microlayer thermophoresis. For example, the ability of a modulated or mutated SOUL heme-binding protein to bind to another molecule can be determined by performing a co-immunoprecipitation experiment using a modulated or mutated SOUL heme-binding protein and a corresponding unmodified or unmutated SOUL heme-binding protein. If the modulation or mutation of the SOUL heme-binding protein reduces, inhibits, or eliminates the ability of the SOUL heme-binding protein to bind to another molecule, the co-immunoprecipitation will show that the modulated or mutated SOUL heme-binding protein binds less to the other molecule.
[0230] According to the present invention, the activity or expression of SOUL heme-binding protein is modulated.
[0231] In one aspect, the present invention provides a method for modulating (i.e., increasing or decreasing) the alkaloid content of a plant or a part or cell thereof (e.g., a plant cell), comprising modifying the plant by modulating (i.e., increasing or decreasing) the expression of at least one gene encoding a SOUL heme-binding protein.
[0232] "Expression" of a gene refers to the degree to which the information encoded in the gene is converted into function. The expression level of a gene can be equated with the amount of the gene product present in a cell or organism. Modifications that modulate (i.e., increase or decrease) gene expression are modifications that increase the amount of the gene product in a plant or cell compared to an unmodified plant or cell.
[0233] In some embodiments, expression of the SOUL heme-binding protein is modulated (ie, increased or decreased) compared to expression of a gene encoding the SOUL heme-binding protein in a plant (eg, a tobacco plant) that has not been modified according to the invention.
[0234] In some embodiments, expression of the SOUL heme-binding protein may be modulated (i.e., increased or decreased) by at least about 10%, 20%, 30%, or 40%, suitably at least about 50%, 60%, 70%, more suitably at least about 80%, 90%, 95%, or 100%, compared to the expression of a gene encoding the SOUL heme-binding protein in a plant (e.g., a tobacco plant) not modified according to the invention.
[0235] In some embodiments, the modulated SOUL heme-binding protein exhibits increased or decreased expression compared to unmodified SOUL heme-binding protein. The modulated SOUL heme-binding protein can exhibit at least about 1%, at least about 3%, at least about 5%, at least about 10%, at least about 20%, at least about 30%, at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, or at least about 90% increased or decreased expression compared to unmodified SOUL heme-binding protein.
[0236] Typically, genes are transcribed into mRNA, which is translated into proteins, the ultimate gene products. Proteins can be sequestered in cells for storage and / or degraded. Gene expression can be modulated by regulating any or all of these steps. Thus, in some embodiments, the modification modulates expression of at least one SOUL hemoglobin-binding protein gene in one of the following ways:
[0237] regulating transcription from at least one SOUL heme-binding protein gene;
[0238] regulating translation of mRNA from at least one SOUL heme-binding protein gene;
[0239] Modulating the release of SOUL heme-binding protein from intracellular stores; and / or
[0240] Regulates the degradation rate of SOUL heme-binding protein.
[0241] The expression of a specific gene encoding the SOUL heme-binding protein can be measured by measuring the transcription and / or translation of the gene. Methods for measuring transcription are well known in the art and include, among others, northern blotting, RNA-Seq, in situ hybridization, DNA microarrays, and RT-PCR. Alternatively, the expression of a gene can be measured indirectly by measuring the level of a gene product, such as a protein encoded by the gene. For example, the expression of the SOUL heme-binding protein can be determined by measuring the presence of the protein by western blotting using an antibody specific for the SOUL heme-binding protein (e.g., an antibody specific for the SOUL motif).
[0242] Modification
[0243] As used herein, the term "modification" refers to an alteration of the genetic material of a plant or cell. The plant or cell can be modified in any manner that modulates the activity or expression of at least one gene encoding a SOUL heme-binding protein. The types of modifications to plants and cells that modulate the activity or expression of genes, as well as techniques for achieving these modifications, are known in the art.
[0244] In some embodiments, the present invention provides a method of reducing the alkaloid content of a plant or a part or cell thereof (e.g., a plant cell), comprising modifying the plant by reducing or inhibiting the activity or expression of at least one gene encoding a SOUL heme-binding protein.
[0245] In some embodiments, the present invention provides a method for reducing the level of tobacco-specific nitrosamines (TSNAs) or precursors of TSNAs in a tobacco plant or plant part thereof, the method comprising modifying the plant or cell or cell culture by reducing the activity or expression of at least one gene encoding a SOUL heme-binding protein.
[0246] Any method known in the art for reducing or inhibiting the activity or expression of a gene can be used in the methods according to the present invention.
[0247] Suitably, the activity or expression of the SOUL heme-binding protein gene may be reduced, partially inactivated, inhibited, eliminated, knocked out or lost such that the protein activity, expression or function of the SOUL heme-binding protein gene is undetectable.
[0248] In one aspect, at least one SOUL hemoglobin-binding protein gene is knocked out. In other words, the SOUL hemoglobin-binding protein gene has been rendered completely ineffective.
[0249] For example, the method may include:
[0250] ● providing a mutation in a nucleic acid sequence encoding a protein comprising an amino acid sequence as shown in SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22, or an amino acid sequence having at least 80% sequence identity thereto;
[0251] ● providing a mutation in a regulatory region (e.g., a promoter or enhancer) that helps control the expression of a protein comprising an amino acid sequence as shown in SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22, or an amino acid sequence having at least 80% sequence identity thereto;
[0252] ● Provide antisense RNA, siRNA or miRNA that reduces the level of a nucleic acid sequence encoding a protein comprising an amino acid sequence as shown in SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22, or an amino acid sequence having at least 80% sequence identity thereto.
[0253] Each of the above methods results in a reduction or inhibition of the activity or expression of a protein comprising an amino acid sequence as shown in SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22, or an amino acid sequence having at least 80% sequence identity thereto, or wherein at least one gene encoding a SOUL heme-binding protein comprises a nucleotide sequence as shown in SEQ ID No. 2, 3, 5, 6, 8, 9, 11, 12, 14, 15, 17, 18, 20, 21, 23 or 24, or a functional variant or functional fragment or ortholog of SEQ ID No. 2, 3, 5, 6, 8, 9, 11, 12, 14, 15, 17, 18, 20, 21, 23 or 24, or a nucleic acid sequence having at least 80% identity thereto.
[0254] As used herein, the term "mutation" includes natural genetic variants or engineered variants. Specifically, the term "mutation" refers to a variation in a nucleotide sequence encoding an amino acid sequence or an amino acid sequence compared to a sequence as shown in SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22, or an amino acid sequence having at least 80% (preferably at least 85%, preferably at least 90%, preferably at least 93%, preferably at least 95%, preferably at least 98%, preferably at least 99%) sequence identity thereto.
[0255] In one embodiment, the mutation reduces the alkaloid content of the plant. In another embodiment, the mutation reduces the content of at least one TSNA or TSNA precursor in tobacco.
[0256] In one embodiment, the method according to the invention may comprise providing a nucleic acid sequence to a plant or part thereof or a plant cell, wherein said nucleic acid results in a reduction or elimination of the activity or expression of at least one gene encoding a SOUL heme-binding protein.
[0257] In one embodiment, the method according to the invention may comprise providing a plant or part thereof or a plant cell with a nucleic acid sequence, wherein the nucleic acid results in the modification of the nucleic acid sequence of at least one gene encoding a SOUL heme-binding protein.
[0258] Suitably, the nucleic acid sequence may be introduced into a plant or part or cell thereof. Suitably, an endogenous nucleic acid sequence in a plant or part or cell thereof may be modified to encode a polypeptide according to the invention (e.g., by gene editing). For example, an endogenous nucleotide sequence may be modified to reduce the activity or expression of at least one gene encoding a SOUL heme-binding protein.
[0259] In a preferred embodiment, each copy of the nucleic acid sequence encoding a protein comprising the sequence as shown in SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22 or a sequence having at least 80% sequence identity thereto, or wherein the at least one gene encoding the SOUL heme-binding protein comprises the nucleotide sequence as shown in SEQ ID No. 2, 3, 5, 6, 8, 9, 11, 12, 14, 15, 17, 18, 20, 21, 23 or 24, or a functional variant or functional fragment or ortholog of SEQ ID No. 2, 3, 5, 6, 8, 9, 11, 12, 14, 15, 17, 18, 20, 21, 23 or 24, or a functional variant or functional fragment or ortholog of SEQ ID No. 2, 3, 5, 6, 8, 9, 11, 12, 14, 15, 17, 18, 20, 21, 23 or 24 nucleic acid sequences with at least 80% identity (which are present in the plant) are modified, e.g., mutated as defined herein (e.g., each genomic copy of the gene encoding the protein in the plant is mutated). For example, each copy of the gene in the allotetraploid genome of tobacco may be mutated.
[0260] In a preferred embodiment, some or all of the homologues of the SOUL hemoglobin-binding proteins described herein are modified, e.g., inhibited or mutated. Suitably, some or all of SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22, or corresponding sequences having at least 80% sequence identity thereto, are modified, e.g., inhibited or mutated.
[0261] In some embodiments, the plant or plant cell according to the present invention is homozygous. Suitably, the plant or plant cell may be homozygous for a modification such as an inhibition or mutation.
[0262] In some embodiments, plants or plant cells according to the present invention express only modified, e.g., mutated, nucleic acids encoding SOUL heme-binding protein. In other words, in some embodiments, no endogenous (or endogenous and functional) protein is present in the plants according to the present invention. In other words, if any endogenous protein is present, it is preferably in an inactive form.
[0263] In one embodiment, the method may comprise providing a mutation in a nucleic acid sequence as shown in SEQ ID No. 2, 3, 5, 6, 8, 9, 11, 12, 14, 15, 17, 18, 20, 21, 23 or 24, or a nucleic acid sequence having at least 80% identity thereto.
[0264] The mutation may alter the plant genome such that the nucleic acid sequence encoding a protein comprising an amino acid sequence as set forth in SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22, or an amino acid sequence having at least 80% sequence identity thereto, is completely or partially deleted or otherwise modified to inhibit or eliminate the ability of the SOUL heme-binding protein to interact with other molecules, such as to bind to other molecules, compared to the protein set forth in SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22, or a sequence having at least 80% sequence identity thereto. In some embodiments, the mutation does not alter the level or expression of the protein, but reduces, inhibits or eliminates the ability of the SOUL heme-binding protein to interact with other molecules, such as to bind to other molecules, compared to the protein set forth in SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22, or a sequence having at least 80% sequence identity thereto. Suitably, the mutation inhibits or eliminates the ability of the SOUL heme-binding protein to interact with other proteins. Suitably, the mutation inhibits or eliminates the ability of SOUL heme-binding protein to bind to other molecules. Suitably, the mutation inhibits or eliminates the ability of SOUL heme-binding protein to bind to other proteins. Suitably, the mutation inhibits or eliminates the ability of SOUL heme-binding protein to bind to tetrapyrroles or tetrapyrroles. Suitably, the mutation inhibits or eliminates the ability of SOUL heme-binding protein to bind to heme. The expression "inhibits or eliminates" means reducing the interaction between SOUL heme-binding protein and other molecules, suitably to the extent that the interaction is prevented (i.e., the SOUL heme-binding protein does not interact with the other molecule at all). Suitably, the inhibition or elimination of the binding of SOUL heme-binding protein to another molecule means that the binding affinity of SOUL heme-binding protein to the other molecule is reduced. In some embodiments, the mutation reduces the binding affinity of SOUL heme-binding protein to heme.
[0265] Suitably, the mutation may be in a domain of the SOUL heme-binding protein that mediates interactions with other molecules. The mutation may be in a domain of the SOUL heme-binding protein that mediates binding to heme. The mutation may be in the SOUL motif of the SOUL heme-binding protein. In some embodiments, the SOUL motif may be mutated to thereby alter the ability of the SOUL heme-binding protein to interact with other molecules. In other words, the SOUL motif may be mutated to alter the binding affinity of the SOUL heme-binding protein for other molecules. Suitably, the SOUL motif is mutated to increase the binding affinity of the SOUL heme-binding protein for other molecules. Suitably, the SOUL motif is mutated to decrease the binding affinity of the SOUL heme-binding protein for other molecules.
[0266] The mutation may interrupt the nucleic acid sequence encoding a protein comprising the amino acid sequence shown in SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22, or an amino acid sequence having at least 80% sequence identity thereto.
[0267] The interruption may result in the nucleic acid sequence not being transcribed and / or translated.
[0268] The nucleic acid sequence can be interrupted, for example, by deleting or otherwise modifying the ATG start codon of the nucleic acid sequence such that translation of the protein is reduced or prevented.
[0269] The nucleotide sequence may comprise one or more nucleotide changes that reduce or prevent protein expression or influence protein transport. For example, protein expression may be reduced or prevented by introducing one or more premature stop codons, frameshifts, splice mutations, or non-tolerant amino acid substitutions into the open reading frame.
[0270] A premature stop codon refers to a mutation that introduces a stop codon into the open reading frame and prevents translation of the entire amino acid sequence. The premature stop codon can be a TAG ("amber"), TAA ("ochre"), or TGA ("opal" or "umber") codon.
[0271] Frameshift mutations (also known as framing errors or frame shifts) are mutations caused by the insertion / deletion (insertion or deletion) of multiple nucleotides in a nucleic acid sequence that cannot be divided by three. Due to the triplet nature of gene expression through codons, insertions or deletions can change the reading frame, resulting in a translation that is completely different from the original. Frameshift mutations will often cause the mutated codon to be read to encode a different amino acid. Frameshift mutations will generally result in the introduction of premature stop codons.
[0272] Splicing mutations insert, delete, or change a number of nucleotides at specific sites where splicing occurs during the processing of precursor messenger RNA into mature messenger RNA. The loss of splicing sites results in one or more introns remaining in the mature mRNA and may lead to the production of abnormal proteins.
[0273] Non-tolerant amino acid substitutions refer to mutations that cause non-synonymous amino acid substitutions in a protein, which result in reduced or eliminated function of the protein.
[0274] Any method known in the art for providing mutations in nucleic acid sequences can be used in the methods according to the present invention. For example, homologous recombination can be used to generate vectors in which one or more related nucleic acid sequences are mutated and used to transform plants or plant cells. Recombinant plants or plant cells expressing the mutated sequences can then be selected.
[0275] In one embodiment, the mutation introduces a non-tolerant amino acid substitution in a protein comprising an amino acid sequence as shown in SEQ ID No. 1, 4, 7, 10, 13, 16, 19 or 22, or a sequence having at least 80% sequence identity thereto.
[0276] In some embodiments, the SOUL motif can contain a mutation that reduces expression of at least one gene encoding a SOUL heme-binding protein.
[0277] The mutation may be a deletion, a splice mutant, or a codon encoding a non-tolerant amino acid substitution.
[0278] In one embodiment, the nucleic acid sequence encoding the SOUL heme-binding protein may be deleted in whole or in part. The deletion may be continuous or may comprise multiple segments of the sequence. The deletion preferably removes a sufficient amount of nucleotide sequence such that the nucleic acid sequence no longer encodes a functional SOUL heme-binding protein. The deletion may be complete, in which case 100% of the coding portion of the nucleic acid sequence is absent when compared to the corresponding genome of a comparable unmodified plant. The deletion may, for example, remove at least 50, 60, 70, 80, or 90% of the coding portion of the nucleic acid sequence. Suitably, at least a portion of the protein may be deleted. The deletion may, for example, remove at least 10, 20, 30, 40, 50, 60, 70, 80, or 90% of the coding portion of the protein.
[0279] The deletion may remove at least a portion of the SOUL motif.
[0280] The deletion may, for example, remove at least 10, 20, 30, 40, 50, 60, 70, 80 or 90% of the SOUL motif.
[0281] Suitably, the deletion may remove at least 5 amino acids, at least 10 amino acids, at least 15, at least 20, at least 25, at least 30 amino acids from the SOUL motif. Suitably, the deletion may remove at least 5 amino acids, at least 10 amino acids, at least 15, at least 20, at least 25, at least 30 amino acids from the SOUL motif.
[0282] In one embodiment, the deletion can remove at least 100 amino acids, at least 150, at least 200, at least 250, at least 300, at least 350 amino acids from the C-terminus of the SOUL heme-binding protein.
[0283] Suitably, the mutant protein may be a truncated protein lacking at least about 100 amino acids, at least about 150 amino acids corresponding to the amino acids from the C-terminus of SEQ ID No. 1, or a sequence having at least 80% (preferably at least 85%, at least, at least 90%, at least 95%, at least 98%) sequence identity to a truncated protein lacking at least about 100 amino acids, at least about 150 amino acids corresponding to the amino acids from the C-terminus of SEQ ID No. 1.
[0284] Methods for deleting nucleic acid sequences in plants are known in the art. For example, homologous recombination can be used to produce a vector in which one or more related nucleic acid sequences are lost and used to transform a plant or plant cell. Recombinant plants or plant cells expressing the new sequence portion can then be selected.
[0285] Plant cells transformed with the vectors described herein can be grown and maintained according to well-known tissue culture methods, such as by culturing the cells in a suitable medium supplied with necessary growth factors such as amino acids, plant hormones, vitamins, and the like.
[0286] Targeted mutagenesis methods (also referred to as targeted nucleotide exchange (TNE) or oligonucleotide directed mutagenesis (oligo-directed mutagenesis) (ODM)) can be used to modify nucleotide sequences. Targeted mutagenesis methods include, but are not limited to, those employing zinc finger nucleases, TALENs (see WO2011 / 072246 and WO2010 / 079430), Cas9-samples, Cas9 / crRNA / tracrRNA, Cas9 / gRNA or other CRISPR systems (see WO2014 / 071006 and WO2014 / 093622), meganucleases (see WO2007 / 047859 and WO2009 / 059195), or employing the targeted mutagenesis methods of mutagenic oligonucleotides, which may contain chemically modified nucleotides (such as Or TALENs) for enhancing mutagenesis with sequence complementarity to genes that enter plant protoplasts.
[0287] Alternatively, mutagenesis systems such as TILLING (Targeting Induced Local Lesions IN Genomics; McCallum et al. (2000) Nat. Biotech. 18:455, and McCallum et al. (2000) Plant Physiol. 123, 439-442, both incorporated herein by reference) can be used to generate plant lines comprising genes encoding proteins with mutations. TILLING uses traditional chemical mutagenesis (e.g., ethyl methanesulfonate (EMS) mutagenesis to generate random mutations) followed by high-throughput screening of mutations. Thus, plants, seeds, cells, and tissues comprising genes with desired mutations can be obtained.
[0288] Said method may comprise the following steps: mutagenesis plant seeds (for example EMS mutagenesis), the merging of plant individual or DNA, the pcr amplification of target region, heteroduplex formation and high throughput detection, the evaluation of mutant plant, the order-checking of mutant pcr product.Should be understood that other mutagenesis and selection methods can be used to generate the plant of this type of modification equally.Seed can for example be irradiated or chemically treated, and can be for the phenotypic screening plant of modification.
[0289] Fast neutron deletion mutagenesis can be used in a reverse genetics sense (i.e., using PCR) to identify plant lines carrying deletions in endogenous genes. See, e.g., Ohshima et al. (1998) Virology 213:472-481; Okubara et al. (1994) Genetics 137:867-874; and Quesada et al. (2000) Genetics 154:421-4315, which are incorporated herein by reference.
[0290] In another approach, dominant mutants can be used to trigger RNA silencing due to gene inversion and recombination of duplicated loci. See, e.g., Kusaba et al. (2003) Plant Cell 15: 1455-1467 (incorporated herein by reference).
[0291] Modified plants can be distinguished from unmodified plants, i.e., wild-type plants, by molecular methods, such as one or more mutations present in the DNA, and by the phenotypic characteristics of the modification. The modified plants can be homozygous or heterozygous for the modification. Preferably, the modified plants are homozygous for the modification.

[0367] Commercially desirable traits
[0368] In one embodiment, the plants of the present invention have a modified (i.e., increased or decreased) total alkaloid content, and / or a modified (i.e., increased or decreased) content of one or more alkaloids selected from nicotine, nornicotine, anabasine, mithofamine, and anatabine, and / or decreased nicotine, while at least maintaining the flavor profile and / or other commercially desirable traits. In one embodiment, the plants of the present invention produce leaves of similar grade and / or quality to plants that have not been modified according to the present invention.
[0369] In one embodiment, the plants of the invention have reduced nicotine content without a significant change in the flavor profile of the plant (eg, compared to the same plant that has not been modified according to the invention).
[0370] In one embodiment, the plants of the present invention have a modified (i.e., increased or decreased) alkaloid and / or TSNA content (e.g., compared to the same plant that has not been modified according to the present invention) without a significant change (e.g., a decrease) in other commercially desirable traits of the plant. In particular, the yield of the modified plant is preferably not reduced compared to the same plant that has not been modified according to the present invention.
[0371] Thus, in one embodiment, the methods and uses of the present invention relate to modifying (i.e. increasing or decreasing) the total alkaloid content, and / or modifying (i.e. increasing or decreasing) one or more alkaloids selected from nicotine, nornicotine, anabasine and anatabine, and / or modifying (i.e. increasing or decreasing) the nicotine content and / or TSNA content, while maintaining the flavor profile and / or other commercially desirable traits (e.g. yield).
[0372] As used herein, the term "commercially desirable traits" will include traits such as yield, mature plant height, number of harvestable leaves, average node length, cutter leaf length, cutter leaf width, quality (e.g., leaf mass, appropriately modulated leaf mass), abiotic (e.g., drought) stress tolerance, herbicide tolerance, and / or biotic (e.g., insect, bacterial, or fungal) stress tolerance.
[0373] Leaf quality can be measured based on the color, texture, and aroma of the cured leaves, for example according to United States Department of Agriculture (USDA) grades and standards.
[0374] Tobacco grades are evaluated based on factors including, but not limited to, petiole position, leaf size, leaf color, leaf uniformity and integrity, maturity, texture, elasticity, gloss (related to the intensity and depth of color and shine of the leaf), hygroscopicity (the ability of the tobacco leaf to absorb and retain moisture from the environment), and green nuance or cast.
[0375] Leaf grade can be determined using standard methods known in the art, for example, using the Official Standard Grades (7 USC §511) published by the Agricultural Marketing Service of the US Department of Agriculture. See, e.g., the official standard grades for Burley Tobacco (U.S. Type 31 and Foreign Type 93), effective November 5, 1990 (55 FR 40645); the official standard grades for Flue-cured Tobacco (U.S. Types 11, 12, 13, 14 and Foreign Type 92), effective March 27, 1989 (54 FR 7925); the official standard grades for Pennsylvania Seedleaf Tobacco (U.S. Type 41), effective January 8, 1965 (29 FR 16854); the official standard grades for Ohio Cigar-Leaf Tobacco (U.S. Types 42, 43, and 44), effective December 8, 1963 (28 F.R. 11719 and 28 FR 11719). 11926); the official standard grade for Wisconsin Cigar-Binder Tobacco (U.S. 54 and 55), effective November 20, 1969 (34 FR 17061); the official standard grade for Wisconsin Cigar-Binder Tobacco (U.S. 54 and 55), effective November 20, 1969 (34 F.R. 17061); the official standard grade for Georgia and Florida Shade-Grown Cigar-Wrapper Tobacco (U.S. 62), effective April 1971. USDA grade index values may be determined based on industry-recognized grade indices. See, e.g., Bowman et al. (1988) Tobacco Science, 32:39-40; Legacy Tobacco Document Library (Bates Document #523267826-523267833, July 1, 1988, Memorandum on the Proposed Burley Tobacco Grade Index); and Miller et al. (1990) Tobacco Intern., 192:55-57 (all of the foregoing references are incorporated herein in their entireties).
[0376] In one aspect, the USDA grade index is a 0-100 numerical representation of the received federal grade and is a weighted average of all shank positions. A higher grade index indicates higher quality. Alternatively, the blade grade can be determined via hyper-spectral imaging. See, for example, WO 2011 / 027315 (which is incorporated herein by reference).

[0445] As used herein, the term "processed tobacco leaf" refers to a tobacco leaf that has undergone one or more processing steps to which tobacco is subjected in the art."Processed tobacco leaf" contains no or substantially no living cells.
[0446] The term "living cell" refers to a cell that is capable of growth and / or metabolic activity. Thus, if a cell is said to be not living, also known as "non-viable", the cell does not exhibit the characteristics of a living cell.
[0447] The term "substantially free of living cells" means that less than about 5% of all cells are living. Preferably, less than about 3%, more preferably less than about 1%, even more preferably less than about 0.1% of all cells are living.
[0448] In one embodiment, processed tobacco leaves may be processed by one or more of: curing, fermenting, and / or pasteurizing.
[0449] Suitably, the processed tobacco leaves may be processed by curing.
[0450] The tobacco leaves may be cured by any method known in the art. In one embodiment, the tobacco leaves may be cured by one or more curing methods selected from the group consisting of air-curing, flame-curing, flue-curing, and sun-curing.
[0451] Suitably, the tobacco leaves may be air-cured.
[0452] Typically, air-curing is achieved by hanging the tobacco leaves in a well-ventilated barn and allowing them to dry. This is usually done over a period of four to eight weeks. Air-curing is particularly suitable for Burley tobacco.
[0453] Suitably, the tobacco leaves may be open fire cured. Open fire curing is usually achieved by hanging the tobacco leaves in large curing barns where a hardwood fire is kept burning low, either continuously or intermittently, and typically takes from three days to ten weeks, depending on the process and the tobacco.
[0454] In another embodiment, the tobacco leaves can be flue-cured. Flue-curing can include stringing tobacco leaves onto tobacco rods and hanging them on tier-poles in a curing barn. Curing barns typically have flues that operate with an externally supplied firebox. Typically, this results in tobacco that has been heat-cured without being exposed to smoke. Typically, the temperature rises slowly during the curing process, and the entire process takes about 1 week.
[0455] Suitably, the tobacco leaves may be sun-cured. This process generally involves exposing uncovered tobacco to the sun.
[0456] Suitably, the processed tobacco leaves may be processed by fermentation.
[0457] Fermentation can be carried out in any manner known in the art. Usually, during the fermentation, tobacco leaves are piled into a tobacco pile (heap) covered with a modulation in a sack for example to retain moisture. The combination of the residual water in the leaf and the tobacco weight has generated the natural heat that makes tobacco ripe. The temperature in the center of the heap is monitored every day. In some methods, the whole heap is opened weekly. The leaves are then taken out to shake and moisten, and the heap is rotated so that the inner leaves are outside and the bottom leaves are placed on the top of the heap. This ensures the uniform fermentation of the whole heap. The extra moisture on the leaf adds the actual rotation generation heat of the leaf itself, thereby releasing the natural ammonia of the tobacco and reducing nicotine, while also deepening color and improving the aroma of the tobacco. Usually, the fermentation process continues up to 6 months, and this depends on the variety of the tobacco, the handle position on the leaf, the thickness of the leaf and the intended use.
[0458] Suitably, the processed tobacco leaves may be processed by pasteurisation.Pasteurisation may be particularly preferred when the tobacco leaves are to be used in the preparation of smokeless tobacco industrial products, most preferably snus.
[0459] The pasteurization of tobacco leaves can be carried out by any method known in the art. For example, the pasteurization method can be as described in J Foulds, L Ramstrom, M Burke, K Fagerstrom. Effect of smokeless tobacco (snus) on smoking and public health in Sweden. Tobacco Control (2003) 12 : 349–359 (the teachings of which are incorporated herein by reference).
[0460] During snus production, pasteurization is typically performed by a process in which the tobacco is heat-treated with steam for 24-36 hours, reaching a temperature of approximately 100° C. This results in a virtually sterile product, and without wishing to be bound by theory, one of the consequences of this is believed to be limiting further TSNA formation.
[0461] In one embodiment, the pasteurization process may be steam pasteurization.
[0462] In some embodiments, the processed tobacco leaves can be cut. The processed tobacco leaves can be cut before or after processing. Suitably, the processed tobacco leaves can be cut after processing.
[0463] In one embodiment, use of the foregoing embodiments can provide reconstituted tobacco.
[0464] In one embodiment, reconstituted tobacco is provided.
[0465] As used herein, "reconstituted" may also be referred to as reconstituted, recycled or homogenized sheet tobacco, and refers to tobacco material generated from processed tobacco leaf residues. Reconstituted tobacco allows the production of consistent, high-quality blends and allows the ratios of the various components to be adjusted.
[0466] Reconstituted tobacco can be nanofibre reconstituted (nanofibres can be extracted in solid or liquid form), paper reconstituted (which uses stems, chips and midrib as raw materials), or slurry reconstituted (which uses a mixture of finely ground material and tobacco stems mixed with water and a plant binder; the soluble residue is formed into sheets by extracting the water).
[0467] Any method known in the art can be used to prepare reconstituted tobacco, see, for example, CORESTA Congress, Sapporo, 2012, Smoke Science / Product Technology Groups, SSPT 12 (incorporated herein by reference).
[0468] In some embodiments, the leaves of the results of tobacco plants, tobacco plants and / or processed tobacco leaves can be used to extract nicotine. The extraction of nicotine can be achieved using any method known in the art. For example, the method for extracting nicotine from tobacco is taught in US 2,162,738, which is incorporated herein by reference.

[0521] Polynucleotide / polypeptide / construct
[0522] In certain embodiments of the present invention, constructs that modulate the activity or expression of at least one gene encoding a SOUL heme-binding protein may be transformed into plant cells, suitably under the direction of a promoter.
[0523] In certain embodiments of the present invention, a construct that reduces (i.e., inhibits) the activity or expression of at least one gene encoding a SOUL heme-binding protein can be transformed into a plant cell under the guidance of a promoter. For example, the genetic construct can be a gene editing construct or can comprise an RNAi molecule, which can comprise a small interfering RNA (siRNA) molecule or a short hairpin (shRNA) molecule.
[0524] In certain embodiments of the invention, a construct that increases the activity or expression of a gene encoding a SOUL heme-binding protein, such as an endogenous SOUL heme-binding protein, can be transformed into a plant cell, suitably under the direction of a promoter.
[0525] The construct can be introduced into the plant according to the present invention with the aid of a suitable vector, such as a plant transformation vector. The plant transformation vector may comprise an expression cassette comprising a promoter sequence, a construct sequence targeting a gene encoding the SOUL heme-binding protein in the transcriptional direction 5'-3' and optionally a 3' untranslated terminator sequence, including a termination signal for RNA polymerase and a polyadenylation signal for polyadenylase. The promoter sequence may be present in one or more copies, and such copies may be identical or variants of the promoter sequence described above. The terminator sequence may be derived from a plant, bacterial or viral gene. Suitable terminator sequences are, for example, pea. rbcS E9 terminator sequence, derived from Agrobacterium tumefaciens ( Agrobacterium tumefaciens ) of the nopaline synthase gene nos terminator sequence, and from cauliflower mosaic virus 35S Terminator sequences. Other suitable terminator sequences will be readily known to those skilled in the art.
[0526] The constructs of the present invention may also contain gene expression enhancing mechanisms to increase the strength of the promoter. An example of such an enhancer element is the enhancer element derived from a portion of the promoter of the pea plastocyanin gene and is the subject of International Patent Application No. WO 97 / 20056, incorporated herein by reference. Suitable enhancer elements may be, for example, the enhancer element derived from the nopaline synthase gene of Agrobacterium tumefaciens. nos enhancer element, and from cauliflower mosaic virus 35S Enhancer element.
[0527] These regulatory regions may be derived from the same gene as the promoter DNA sequence, or may be derived from tobacco or other organisms, such as from the Solanaceae family or from the subfamily Lycopodiellae ( Cestroideae All regulatory regions should be able to function in the cells of the tissue to be transformed.
[0528] The promoter DNA sequence may be derived from the same gene as the gene of interest, e.g., the gene that the promoter is to direct, such as the gene encoding the SOUL heme-binding protein according to the present invention, the coding sequence used in the present invention, or may be derived from a different gene from tobacco or another organism, e.g., from the Solanaceae family or from the subfamily Lycopodiellae.
[0529] The expression cassette can be incorporated into a basic plant transformation vector such as pBIN 19 Plus 、 pBI 101 , pKYLX71:35S2, pCAMBIA2300 or other suitable plant transformation vectors known in the art. In addition to the expression cassette, the plant transformation vector will contain such sequences as are necessary for the transformation process. These may include Agrobacterium ( Agrobacterium ) vir gene, one or more T-DNA border sequences, and a selectable marker or other means of identifying transgenic plant cells.
[0530] The term "expression vector or plant transformation vector" refers to a construct capable of in vivo or in vitro expression. Preferably, the expression vector is incorporated into the genome of an organism. In one embodiment, the vector of the present invention expresses a protein, such as the SOUL heme-binding protein described herein. The term "incorporated" preferably includes stable incorporation into the genome.
[0531] Techniques for transforming plants are well known in the art and include, for example, Agrobacterium-mediated transformation. The basic principle in the construction of genetically modified plants is to insert genetic information into the plant genome in order to obtain stable maintenance of the inserted genetic material. An overview of general techniques can be found in the literature by Potrykus ( Annu Rev Plant Physiol Plant Mol Biol
[1991] 42:205-225) and Christon (AgroFood-Industry Hi-Tech 1994 Mar / Apr 17-27), which are incorporated herein by reference.
[0532] Typically, in Agrobacterium-mediated transformation, a binary vector carrying the target exogenous DNA, i.e., a construct according to the present invention, is transferred from an appropriate Agrobacterium strain to the target plant by co-cultivation of Agrobacterium with an explant from the target plant. The transformed plant tissue is then regenerated on a selective medium comprising a selective marker and a plant growth hormone. An alternative is the floral dip method (Clough & Bent, 1998 Plant J. December 1998; 16(6): 735-43, incorporated herein by reference), whereby the flower buds of the complete plant are contacted with a suspension of the Agrobacterium strain containing the chimeric gene, and after fruiting, the transformed individuals are germinated and identified by growth on the selective medium. Direct infection of plant tissue by Agrobacterium is a simple technique that has been widely adopted and has been described in Butcher et al. (1980), Tissue Culture Methods for Plant Pathologists , eds. DS Ingrams and JP Helgeson, 203-208, which is incorporated herein by reference.
[0533] Suitable transformation methods include, for example, the use of polyethylene glycol or electroporation, particle bombardment, microinjection, and silicon carbide fibers to transfer genes directly into protoplasts.

(1994) The Plant Journal 6: (6): 941-948 (incorporated herein by reference), and viral transformation techniques are taught in, for example, Meyer et al. (1992) Mol. Gen. Genet. 231 (3): 345-352 (incorporated herein by reference). Cassava mosaic virus is taught as a vector system for plants in Meyer et al. (1992) Gene 110: 213-217 (incorporated herein by reference).

[0534] In a further aspect, the present invention relates to a vector system that carries a construct and introduces it into the genome of an organism such as a plant, suitably a tobacco plant. The vector system may comprise one vector, but it may comprise two vectors. In the case of two vectors, the vector system is generally referred to as a binary vector system. Binary vector systems are described in Gynheung et al., (1980), Binary Vectors, Plant Molecular Biology ManualA3, 1-19, which is incorporated herein by reference.
[0535] A widely adopted system for transforming plant cells uses the Ti plasmid from Agrobacterium tumefaciens or the Ti plasmid from Agrobacterium rhizogenes ( Agrobacterium rhizogenes ) of the Ri plasmid, which was described by An et al. (1986) Plant Physiol. 81, 301-305 and Butcher et al. (1980) Tissue Culture Methods for Plants Pathologists eds.: DS Ingrams and JP Helgeson, 203-208 (incorporated herein by reference). After each method of introducing the desired foreign gene in a plant according to the present invention, the presence and / or insertion of further DNA sequences may be necessary. The use of T-DNA for plant cell transformation has been well studied and is described in EP-A-120516; Hoekema (1985) The Binary Plant Vector System, Offset-drukkerij Kanters BB, Amsterdam Chapter V; Fraley et al. Crit. Rev. Plant Sci. 4: 1-46; and An et al. (1985) EMBO J 4: 277-284 (incorporated herein by reference).
[0536] Plant cells transformed with one or more constructs that modulate the activity or expression of at least one gene encoding a SOUL heme-binding protein can be grown and maintained according to well-known tissue culture methods, such as by culturing the cells in a suitable medium supplied with necessary growth factors such as amino acids, plant hormones, vitamins, and the like.
[0537] The term "transgenic plant" in connection with the present invention includes any plant comprising a construct that modulates the activity or expression of at least one gene encoding a SOUL heme-binding protein according to the present invention. Accordingly, a transgenic plant is a plant that has been transformed with a construct according to the present invention. Preferably, according to the present invention, the transgenic plant exhibits modulated alkaloid content and / or modulated TSNA content (or its precursors). The term "transgenic plant" does not include a native nucleotide coding sequence in its natural environment when under the control of its native promoter (which is also in its natural environment).
[0538] In one aspect, the gene, construct, plant transformation vector or plant cell encoding the SOUL heme-binding protein according to the present invention is in isolated form. The term "isolated" means that the sequence is at least substantially free of at least one other component with which the sequence is naturally associated in nature and as found in nature.
[0539] In one aspect, the gene, construct, plant transformation vector or plant cell encoding the SOUL heme-binding protein according to the present invention is in a purified form. The term "purified" means in a relatively pure state, for example, at least about 90% pure, or at least about 95% pure, or at least about 98% pure.
[0540] As used herein, the term "nucleotide sequence" refers to an oligonucleotide sequence or a polynucleotide sequence, as well as variants, homologues, fragments and derivatives thereof (such as portions thereof). The nucleotide sequence may be of genomic or synthetic or recombinant origin, may be double-stranded or single-stranded, and may represent the sense or antisense strand.
[0541] The term "nucleotide sequence" in relation to the present invention includes genomic DNA, cDNA, synthetic DNA and RNA. Preferably, it means a DNA encoding the present invention, more preferably a cDNA sequence.
[0542] In a preferred embodiment, when relevant to and encompassed by the scope of the present invention itself, the nucleotide sequence, i.e., the gene encoding the SOUL hemoglobin-binding protein, comprises the native nucleotide sequence when in its natural environment and when linked to one or more of its naturally associated sequences that are also in their natural environment. For ease of reference, we shall refer to this preferred embodiment as the "native nucleotide sequence." In this regard, the term "native nucleotide sequence" means the entire nucleotide sequence, which is in its natural environment and, when operably linked to the entire promoter with which it is naturally associated, said promoter is also in its natural environment.
[0543] Nucleotide sequence for the present invention can be present in a vector, wherein the nucleotide sequence is operably linked to a regulatory sequence that can provide expression of the nucleotide sequence by a suitable host organism. Construct for the present invention can be transformed into a suitable host cell as described herein to provide expression of the polypeptide of the present invention. The selection of carriers such as plasmids, cosmids or phage vectors often depends on the host cell to be introduced therein. Carriers can be for example used for the production of RNA in vitro, or for transfection, transformation, transduction or infection of host cells.
[0544] In some applications, the nucleotide sequences used in the present invention are operably linked to regulatory sequences that are capable of providing expression of the nucleotide sequence, for example, by a selected host cell. For example, the present invention includes vectors comprising a nucleotide sequence encoding a gene for the SOUL hemoglobin-binding protein as described herein operably linked to such regulatory sequences, i.e., the vector is an expression vector.
[0545] The term "operably linked" refers to a juxtaposition wherein the components are in a relationship permitting them to function in their intended manner. A regulatory sequence "operably linked" to a coding sequence is ligated in such a manner that expression of the coding sequence is achieved under conditions compatible with the control sequences.
[0546] The term "regulatory sequence" includes promoters and enhancers and other expression regulatory signals. The term "promoter" is used in the ordinary sense of the art, such as an RNA polymerase binding site. The nucleotide sequence within the construct encoding the gene encoding the SOUL heme-binding protein can be operably linked to at least one promoter.
[0547] The term "construct," which is synonymous with terms such as "cassette" or "vector," includes a nucleotide sequence for use in accordance with the present invention attached directly or indirectly to a promoter.
[0548] An example of indirect attachment is to provide a suitable spacer group, such as an intron sequence, such as the Sh1-intron or the ADH intron, between the promoter and the nucleotide sequence of the present invention. The same is true for the term "fused" in connection with the present invention, which includes direct or indirect attachment. In some cases, the term does not include the natural combination of nucleotide sequences that are typically associated with wild-type gene promoters and the coding proteins when they are all in their natural environment. The construct can even contain or express a marker that allows selection of the genetic construct.
[0549] In some embodiments, the promoter can be operably linked to a nucleotide sequence in a construct or vector for regulating the concentration and / or total content of nicotine in a cell or cell culture or a tobacco plant or part thereof.
[0550] In some embodiments, the promoter can be selected from the group consisting of: a constitutive promoter, a tissue-specific promoter, a developmentally regulated promoter, and an inducible promoter.
[0551] In one embodiment, the promoter can be a constitutive promoter.
[0552] Constitutive promoters direct the expression of a gene continuously throughout all parts of the plant during plant development, although the gene may not be expressed at the same level in all cell types. Examples of known constitutive promoters include those associated with the cauliflower mosaic virus 35S transcript (Odell JT, Nagy F, Chua NH. (1985). Identification of DNA sequences required for activity of the cauliflower mosaic virus 35S promoter. Nature. 313 810-2), the rice actin 1 gene (Zhang W, McElroy D, Wu R. (1991). Analysis of rice Act1 5' region activity in transgenic rice plants. Plant Cell 3 1155-65), and the maize ubiquitin 1 gene (Cornejo MJ, Luth D, Blankenship KM, Anderson OD, Blechl AE. (1993). Activity of a maize ubiquitin promoter in transgenic rice. Plant Molec. Biol. 23 567-81). A constitutive promoter, such as the carnation etched ring virus (CERV) promoter (Hull R, Sadler J, Longstaff M (1986) (CaMV / 35S), figwort mosaic virus 35S promoter. The sequence of carnation etched ring virus DNA: comparison with cauliflower mosaic virus and retroviruses. EMBO Journal, 5(2):3083-3090).
[0553] The constitutive promoter may be selected from the group consisting of: the Carnation Etch Ring Virus (CERV) promoter, the Cauliflower Mosaic Virus (CaMV35S promoter), the promoter from the rice actin 1 gene, or the maize ubiquitin 1 gene.
[0554] The promoter can be a tissue-specific promoter. A tissue-specific promoter is a promoter that directs the expression of a gene in one (or several) parts of a plant, typically throughout the life of those plant parts. The category of tissue-specific promoters also generally includes promoters whose specificity is not absolute, i.e., they can also direct expression at lower levels in tissues other than preferred tissues. Tissue-specific promoters include the phaseolin promoter, the legumin b4 promoter, the usp promoter, the sbp promoter, the ST-LS1 promoter, and the B33 (patatin class I promoter).
[0555] In another embodiment, the promoter can be a developmentally regulated promoter.
[0556] Developmentally regulated promoters direct changes in the expression of a gene in one or more parts of a plant at specific times during plant development. The gene may be expressed at different (usually lower) levels in that plant part at other times, and may also be expressed in other plant parts.
[0557] In one embodiment, the promoter can be an inducible promoter.
[0558] Inducible promoter can respond to the expression of inducer-directed gene.In the absence of inducer, gene will not express.Inducer can act directly on promoter sequence, or can work by offsetting the effect of repressor molecule.Inducer can be chemical agent such as metabolite, albumen, growth regulator (such as auxin and salicylic acid that activates OCS promoter) or toxic element, physiological stress such as heat, light (such as soybean SSU promoter), damage (for example nos, nopaline synthase promoter), or osmotic pressure, or the indirect consequence of pathogen or pest effect. The promoter of development regulation can be described as the inducible promoter of specific type, and its response is the environmental stimulation of the specific moment of endogenous inducer produced by plant or in the life history of plant. Examples of known inducible promoters include those associated with wound response, such as described by Warner SA, Scott R, Draper J. ((1993) Plant J. 3 191-201), temperature response, as disclosed by Benfey & Chua (1989) (Benfey, PN, and Chua, NH. ((1989) Science 244 174-181), and chemical induction, such as described by Gatz ((1995) Methods in Cell Biol. 50 411-424).
[0559] The nucleotide sequence encoding the protein having the specific properties of the gene encoding the SOUL heme-binding protein as defined herein or the protein that is suitable for modification can be identified and / or separated and / or purified from any cell or organism that produces the protein. Various methods for the identification and / or separation and / or purification of nucleotide sequences are well known in the art. For example, once the appropriate sequence has been identified and / or separated and / or purified, more sequences can be prepared using PCR amplification techniques.
[0560] In a still further alternative, the nucleotide sequence encoding the SOUL heme-binding protein may be prepared synthetically by established standard methods, such as those described by Beucage et al. (1981). Tetrahedron Letters 22, 1859-1869 (which is incorporated herein by reference), or by the phosphoramidite method described in Matthes et al., (1984) EMBO J 3, 801-805 (which is incorporated herein by reference). In the phosphoramidite method, oligonucleotides are synthesized, for example in an automatic DNA synthesizer, purified, annealed, ligated, and cloned in an appropriate vector.
[0561] As used herein, the term "amino acid sequence" is synonymous with the term "polypeptide" and / or the term "protein". In some cases, the term "amino acid sequence" is synonymous with the term "peptide". In some cases, the term "amino acid sequence" is synonymous with the term "enzyme".
[0562] The present invention also includes the use of sequences that have a certain degree of sequence identity or sequence homology with one or more amino acid sequences of a polypeptide having the specific properties defined herein, or any nucleotide sequence, i.e., a SOUL hemoglobin-binding protein gene encoding such a polypeptide (hereinafter referred to as "one or more homologous sequences"). Here, the term "homolog" means an entity that has a certain degree of homology with the subject amino acid sequence and the subject nucleotide sequence. Here, the term "homology" can be equivalent to "identity".
[0563] Homologous amino acid sequences and / or nucleotide sequences and / or fragments should provide and / or encode polypeptides that retain the functional activity of the SOUL heme-binding protein gene and / or enhance the activity of the SOUL heme-binding protein gene. Typically, homologous sequences will contain, for example, the same active site as the subject amino acid sequence, or will encode the same active site. Although homology can also be considered in terms of similarity (i.e., amino acid residues having similar chemical properties / functions), in the context of the present invention, it preferably refers to homology in terms of sequence identity. Homologous sequences typically retain functional domains or motifs. Suitably, homologs of the SOUL heme-binding protein may contain a heme-binding site.
[0564] In one embodiment, homologous sequences are taken to include amino acid sequences or nucleotide sequences that have one, two or several additions, deletions and / or substitutions compared to the subject sequence.
