Description
[0001] Cross - Reference to Related Applications
[0002] This application claims the benefit of U.S. Provisional Application No. 63 / 376,194, filed on September 19, 2022, and U.S. Provisional Application No. 63 / 491,721, filed on March 22, 2023, under 35 U.S.C.§119(e), the entire contents of each of which are incorporated herein by reference in their entirety.
[0003] Incorporation of Sequence Listing
[0004] The sequence listing contains a file named "ELSS002WO_ST26.xml", which is 540 kilobytes (measured in MS - ), created on September 14, 2023, and contains 305 sequences, the entire contents of which are incorporated herein by reference in their entirety. Technical Field
[0005] This disclosure relates to the field of genetically engineered plants and other organisms, and more particularly to methods and compositions for producing plants and other organisms that exhibit increased yields of mogroside compounds, particularly mogroside V. This disclosure also relates to the use of such plants and other organisms in the production of new ingredients for food and beverages (such as plant extracts containing mogrosides, purified and partially purified components), and the resulting new foods and beverages (as well as other material compositions). Background Art
[0006] In addition to other industries, low - calorie or calorie - free sweeteners, particularly natural low - calorie or calorie - free sweeteners, are becoming increasingly important for the food and beverage industry as alternatives to traditional high - calorie sweeteners and artificial sweeteners. These alternative sweeteners are used as substitutes for artificial sweeteners or high - calorie sweeteners containing sucrose, fructose, and glucose. Like some artificial sweeteners, some of these alternative sweeteners provide a higher sweetening effect than an equivalent amount of caloric sweeteners, and thus require a smaller amount of these alternative sweeteners to achieve a sweetness equivalent to sugar. However, some low - calorie sweeteners may be expensive to produce and / or have adverse flavor characteristics and / or off - flavors, including but not limited to lingering sweetness, delayed onset of sweetness, negative mouthfeel and bitterness, metallic taste, cooling taste, astringency, and licorice - like taste.
[0007] Some natural plants produce low-calorie or calorie-free sweeteners. For example, mogrosides, an important class of natural sweeteners, are chemically a class of triterpene glycosides or mogrol glycosides naturally produced by Siraitia grosvenorii (also known as luohan guo; scientific name: Siraitia grosvenorii). Mogrosides contain "zero" calories (less than 5 calories per 8-ounce serving) and are 100 - 400 times sweeter than sucrose. Mogrosides have also been reported to have a variety of important pharmacological effects. However, although plants like Siraitia grosvenorii produce mogrosides, the production of mogrosides from these plants is limited and expensive due to their limited natural or agricultural production. In addition, Siraitia grosvenorii prefers to grow in subtropical mountainous areas and requires laborious pollination to bear fruit. Furthermore, attempts have been made to produce mogrosides in vitro or in microorganisms, but due to extensive processing and other problems, it has not been proven economically viable.
[0008] Accordingly, there is a need for new compositions and methods for the efficient production of mogrosides. Summary of the Invention

[0389] The present disclosure generally describes transgenic plants and biosynthetic systems for producing mogrosol / mogroside pathway enzymes and mogrosides, and methods for producing such transgenic plants. The following sections provide more detailed descriptions of embodiments of the subject matter.
[0390] I. Mogroside Pathway Enzymes and Mogrosides
[0391] Mogrosides are highly stable molecules based on a triterpene backbone, formed by 1 - 6 different numbers of glucose units attached to the triterpene backbone. Mogrosides can also contain non - glucose moieties, such as momordicoside I. Figure 1 The mogroside biosynthetic pathway from Siraitia grosvenorii is shown (Itkin et al., Proc Nat Acad Sci USA 113:E7619 - E7628, 2016; Seki et al., Biosci. Biotechnol. Biochem. 82:927 - 934, 2018), and certain enzymes capable of catalyzing the reactions in the pathway. Importantly, the enzyme pathway for producing mogrosides according to the present disclosure is not limited by Figure 1 the mechanism shown. Other terpene structures, mogrosol precursors, enzyme - catalyzed reactions, or transformation mechanisms are also possible. Additionally, certain enzymes can catalyze more than one type of reaction, and one or more additional genes can be used to produce any of the mogrosol intermediates, mogrosol, or any of the mogroside compounds.
[0392] Exemplary nucleic acid and protein sequences are provided herein for certain enzymes of the mogroside pathway (also referred to as the mogroside biosynthetic pathway) that are used to convert a mogrosol precursor such as squalene into mogrosol and ultimately various mogroside compounds, including but not limited to mogroside V. Enzymes of the mogroside pathway include but are not limited to squalene epoxidase (SQE), cucurbitadienol synthase (CDS), epoxide or epoxide hydrolase (EPH), various cytochrome P450 enzymes (CYP) including but not limited to CYP72 and CYP87, uridine phosphorylase - dependent glycosyltransferases (UGT) including but not limited to UGT720, UGT94, and UGT74, and may additionally include 3 - hydroxy - 3 - methylglutaryl - CoA reductase (HMGR) or truncated forms thereof, and NADPH:cytochrome P450 reductase (CPR2).
[0393] SQE, CDS, CYP, and EPH are involved in successive steps of producing and converting mogroside precursors such as squalene into mogrol. Intermediate products of the enzymatic pathway include, but are not limited to, 2,3-oxidosqualene, 2,3;22,23-diepoxysqualene, 24,25-epoxycucurbitadienol, and 24,25-dihydroxycucurbitadienol. CDS is an oxidosqualene cyclase that uses 2,3;22,23-diepoxysqualene as its substrate to produce 24,25-epoxycucurbitadienol. Genome analysis shows that Momordica grosvenori has five genes that can encode SQE. Among them, two are strongly expressed at the initial stage of fruit development, such as the CDS, CYP enzymes, and EPH that catalyze subsequent steps. The Momordica grosvenori genome contains eight genes encoding EPH, which catalyze the conversion of 24,25-epoxycucurbitadienol into 24,25-dihydroxycucurbitadienol. Some enzymes can catalyze more than one type of reaction.
[0394] After the formation of mogrol, a series of glycosylations occur to add glucose molecules at the C-3 and C-24 positions, thereby producing mogrosides I-VI with different degrees of glycosylation. The Roman numerals I, II, III, IV, V, and VI represent the number of glucose units in the corresponding glycosylated mogrosides, isomogrosides, or oxymogrosides, respectively. Two UGTs contribute to these steps. One is UGT720, which is strongly expressed at the initial stage of fruit development and transfers one glucose molecule each to the hydroxyl groups at the C-24 and C-3 positions of mogrol. The second is UGT94, which is strongly expressed at the later stage of fruit development and adds sugars to other sugars already present on the receptor molecule.
[0395] Although the mogroside pathway was initially described in Momordica grosvenori (Siraitia grosvenorii), certain non-Momordica plants can prepare tetracyclic triterpenoids similar to mogrol because at least one intermediate such as triterpenoids is present in the cellular pathway. In addition, given that the related pathways for modifying tetracyclic triterpenoids require related enzymes such as reductases, these plants have expressed certain related network enzymes. Although these non-Momordica plants can express enzymes that produce mogrol precursors, these plants cannot naturally produce all the enzymes in a cooperative manner required to produce mogrosides. For example, plants such as cucumber, melon, and watermelon naturally express cucurbitadienol synthase that can produce cucurbitadienol. However, other enzymes such as CYP enzymes that can modify the cucurbitadienol skeleton redirect this intermediate to other terpene derivatives. Therefore, altering the genomes of these non-Momordica plants by recombinant, gene editing, or other modern plant breeding techniques can allow these non-Momordica plants to produce mogrol and mogrosides. Thus, in certain embodiments, one or more additional genes can be introduced into non-Momordica plants, or the enzymes native to such non-Momordica plants can be upregulated to allow the production of intermediate metabolites, thereby producing mogrol, mogrosides, and mogroside-based sweeteners.
[0396] The term "mogroside precursor" broadly encompasses all possible terpene derivatives and intermediates that give rise to mogrol and mogroside compounds, including but not limited to 2,3-oxidosqualene, 2,3;22,23-dioxidosqualene, 24,25-epoxycucurbitadienol and 24,25-dihydroxycucurbitadienol, cucurbitadienol, 11-hydroxy-cucurbitadienol and 11-oxo-cucurbitadienol. Mogrosides refer to any possible glycosylated products of mogrol, including but not limited to: mogroside I, Siratose (a stereoisomer of mogroside I), mogroside VI, mogroside V, isomogroside V, mogroside IV, mogroside III, mogroside IIIE, mogroside IIE, mogroside IIA, mogroside IE and mogroside IA. Other examples of mogrosides include but are not limited to mogroside IIB, 7-oxomogroside IIE, 11-oxomogroside A1, mogroside IIIA2, 11-deoxymogroside III, 11-oxomogroside IVA, 7-oxomogroside V and 11-oxo-mogroside V. Metabolites and derivatives of mogrosides refer to any close variants of mogrosides resulting from metabolic reactions, naturally occurring reactions or non-naturally occurring reactions. Compared with standard mogrosides, derivatives of mogrosides may contain deletions, alterations or additions of atoms or functional groups. However, the metabolites and derivatives of mogrosides substantially retain the same functions and characteristics as standard mogrosides. In some cases, mogroside compounds produced by the transgenic plants and organisms disclosed by the present invention may also undergo non-enzymatic (spontaneous) conversion to other mogroside compounds.
[0397] One or more of these mogroside compounds can be isolated, purified or partially purified from the disclosed transgenic plants or transgenic organisms grown by fermentation techniques. For example, one or more mogroside compounds can be harvested via wet extraction or from an aqueous layer containing mogroside compounds in a large-scale processing step that does not necessarily result in the isolation of a single mogroside compound. Alternatively, the entire transgenic plant (or a part thereof) or transgenic organism that produces mogroside compounds can be dried and ground into a powder or extracted, or the entire transgenic plant (or a part thereof) or transgenic organism that produces mogroside compounds can be minimally processed and used as a food ingredient.
[0398] In certain embodiments, the transgenic plants and organisms disclosed by the present invention will produce unique ratios of mogroside compounds. In some embodiments, the transgenic plants and organisms disclosed by the present invention can produce more of one or more mogroside compounds and less of other mogroside compounds, such as a greater amount of mogroside V compared with other mogroside compounds.
[0399] In a further embodiment, the complete mogroside biosynthetic pathway can be established in a selected plant or organism using a combinatorial approach, for example by endogenously activating one or more nucleic acid sequences of the mogroside biosynthetic pathway that are naturally present in the plant or organism, and providing any nucleic acid sequences of the mogroside biosynthetic pathway that are not naturally present in the plant or organism via one or more expression vectors comprising non-endogenous mogroside biosynthetic pathway nucleic acid sequences.
[0400] In a further embodiment, the transgenic plant or organism can also be engineered to express one or more nucleic acids involved in the biosynthesis of other sweeteners, such as genes involved in the production of serendipide I, α-serenin, steviol glycosides (stevia), rebaudioside M, or glycyrrhizin. Additionally, the transgenic plant or organism can be engineered to produce mogrosides and other sweeteners together in the same plant or organism, such as producing mogrosides and rebaudioside M.
[0401] II. Recombinant Host Cells and Species
[0402] Although transgenic plants are generally described in this disclosure, other host cells and organisms are also contemplated for certain embodiments of this disclosure.
[0403] As used herein, the term "recombinant host cell" is intended to refer to any host cell whose genome has been engineered to contain at least one nucleic acid sequence of the mogroside biosynthetic pathway disclosed herein, which nucleic acid sequences encode one or more polypeptides in certain embodiments. These sequences include, but are not limited to, nucleic acid or amino acid sequences that are not naturally present in the host cell or organism, DNA sequences that are not normally transcribed into RNA or translated into protein ("expressed"), and other sequences that have been altered from those normally present in the host cell, such as by increasing the copy number of a DNA sequence or altering the expression pattern or level of expression.
[0404] In addition to the plant species disclosed herein, many prokaryotes and additional eukaryotes are suitable for use as recombinant hosts in different aspects of this disclosure. In addition to any plant species, the recombinant host cell can be a bacterium, yeast, or fungus. Host cells or species selected for the production of mogroside compounds can be analyzed to determine whether any of the mogroside biosynthetic pathway genes are endogenous to the host cell or species and which mogroside biosynthetic pathway genes are absent. Genes that do not have an endogenous counterpart in the host cell or organism are typically assembled in one or more recombinant constructs and then transformed into the host cell or organism to provide the missing function.
[0405] Exemplary prokaryotic and eukaryotic species that can be used in certain aspects of the present disclosure include, but are not limited to, Agaricus, Aspergillus, Bacillus, Candida, Corynebacterium, Escherichia, Fusarium / Gibberella, Kluyveromyces, Laetiporus, Lentinus, Phaffia, Phanerochaete, Pichia, Physcomitrella, Rhodoturula, Saccharomyces, Sphaceloma, Schizosaccharomyces, Xanthophyllomyces, and Yarrowia. In some embodiments, the recombinant host can be a microorganism, such as Pichia pastoris, Schizosaccharomyces pombe, Aspergillus niger, or Saccharomyces cerevisiae. In some embodiments, the recombinant host can be a microorganism, such as Escherichia coli or Agrobacterium tumefaciens. It should be understood that certain microorganisms can be used for screening and testing target genes in a high-throughput manner, while other microorganisms with desired productivity or growth characteristics can be used for large-scale production of mogroside compounds. In certain embodiments, food-grade microorganisms can be used for large-scale production purposes.
[0406] III. Nucleic Acid and Polypeptide Sequences
[0407] Certain embodiments of the present disclosure relate to nucleic acid sequences (polynucleotides) of genes in the mogroside biosynthetic pathway and the corresponding amino acid sequences (proteins or polypeptides). Complementary sequences of any nucleic acid or protein sequence described herein are also provided.
[0408] As is well known in the art, "identity" is a relationship between two or more polypeptide sequences or two or more polynucleotide sequences as determined by comparing the sequences. In the art, "identity" also refers to the degree of sequence relatedness between polypeptide or polynucleotide sequences as determined by the matches between these sequence strings. Methods for determining "identity" are designed to give the maximum match between the test sequences. In addition, methods for determining identity are incorporated into publicly available programs. "Identity" can be readily calculated by any of a number of methods known to those skilled in the art. Computer programs can be used to determine the "identity" between two sequences, and these programs include, but are not limited to, GCG; the 5 BLAST program suites, 3 designed for nucleotide sequence queries (BLASTN, BLASTX, and TBLASTX), and 2 designed for protein sequence queries (BLASTP and TBLASTN). The BLASTX program is publicly available from NCBI and other sources (BLAST Manual, NCBI NLM NIH, Bethesda, Md. 20894). The well-known Smith Waterman algorithm can also be used to determine identity.
[0409] According to the present disclosure, a polynucleotide or polypeptide sequence as described herein may exhibit at least about 34%, 40%, 50%, 60%, 62% or 70% to about 100% sequence identity with at least one sequence described herein. For example, in one embodiment, a mogroside biosynthetic pathway gene as described herein may have sequence identity of, for example, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 45%, 46%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% with a sequence selected from SEQ ID NO: 1, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 38, 42, 46, 50, 54, 85 or 87 - 92, or its complement. In other embodiments, a mogroside biosynthetic pathway protein as described herein may have sequence identity of, for example, 34%, 35%, 36%, 37%, 38%, 99% or 100% with a sequence selected from SEQ ID NO: 2, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35 - 37, 39 - 41, 43 - 45, 47 - 49, 51 - 53, 55 - 57 or 86.
[0410] Parameters for polypeptide sequence comparison include the following: algorithm: Needleman and Wunsch (J. Mol. Biol. 48:443 - 453, 1970); comparison matrix: BLOSUM62 from Hentikoff and Hentikoff, (Proc. Natl. Acad. Sci. USA 89:10915 - 10919, 1992); gap penalty: 12; and gap length penalty: 4. Programs that can be used with these parameters are publicly available as the "GAP" program from Genetics Computer Group, Madison WI. The above parameters and no penalty for terminal gaps can be used as the default parameters for peptide comparison.
[0411] Parameters for nucleic acid sequence comparison include the following: algorithm: Needleman and Wunsch (ibid.); comparison matrix: match = +10; mismatch = 0; gap penalty: 50; and gap length penalty: 3. Programs that can be used with these parameters are publicly available as the "Gap" program from Genetics Computer Group, Madison Wis. The above parameters can be used as the default parameters for nucleic acid comparison.
[0412] As used herein, "hybridize", "hybridized", or "capable of hybridizing" shall be understood to mean the formation of a double-stranded or triple-stranded molecule or a molecule having a partially double-stranded or triple-stranded nature. Such hybridization can be carried out under relatively high stringency conditions, including low salt and / or high temperature conditions, for example by washing for 10 minutes at a temperature of about 50°C to about 70°C in about 0.02M to about 0.15M NaCl. In one embodiment of the present disclosure, the conditions are 0.15M NaCl and 70°C. Stringent conditions allow for little or no mismatch between the nucleic acid and the target strand. Such conditions are well known to those of ordinary skill in the art and are preferred for applications requiring high selectivity. Non-limiting applications include isolating nucleic acids, such as genes or nucleic acid fragments thereof, or detecting at least one specific mRNA transcript or nucleic acid fragment thereof, etc. Also included are proteins or polypeptides, or fragments thereof, such as any of those described herein.
[0413] With respect to the nucleic acid sequences disclosed herein, "fragment" refers to any portion of a polynucleotide molecule that retains useful functional properties. Useful fragments include oligonucleotides and polynucleotides that can be used as probes or primers in hybridization or amplification techniques or in the regulation of replication, transcription, or translation. A polynucleotide fragment refers to any subsequence of a polynucleotide, typically at least about 15 consecutive nucleotides, at least about 16 consecutive nucleotides, at least about 17 consecutive nucleotides, at least about 18 consecutive nucleotides, at least about 19 consecutive nucleotides, at least about 20 consecutive nucleotides, at least about 21 consecutive nucleotides, at least about 22 consecutive nucleotides, at least about 23 consecutive nucleotides, at least about 24 consecutive nucleotides, at least about 25 consecutive nucleotides, at least about 30 consecutive nucleotides, at least about 35 nucleotides, at least about 40 consecutive nucleotides, at least about 45 consecutive nucleotides, or at least about 50 or more nucleotides of any nucleic acid sequence provided herein.
[0414] As disclosed herein, a fragment can also include a subsequence of a polypeptide and protein molecule, or a subsequence of a polypeptide. The fragment can have antigenic potential, or can be a subsequence of a polypeptide that performs at least one biological function of the full-length polypeptide in substantially the same manner or to a similar extent as the full-length polypeptide. The size of the fragment can vary from as few as 5 amino acids to the full length of the full-length polypeptide, but is preferably at least about 10 amino acid lengths, at least about 15 amino acid lengths, at least about 20 amino acid lengths, at least about 25 amino acid lengths, at least about 30 amino acid lengths, at least about 35 amino acid lengths, at least about 40 amino acid lengths, at least about 45 amino acid lengths, at least about 50 amino acid lengths, at least about 55 amino acid lengths, or at least about 60 amino acid lengths or more of any of the amino acid sequences provided herein.
[0415] The nucleic acids of SEQ ID NO:1, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 38, 42, 46, 50, 54, 58, 85 or 87 - 92 provided herein and the amino acids of SEQ ID NO:2, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35 - 37, 39 - 41, 43 - 45, 47 - 49, 51 - 53, 55 - 57, 59 or 86 provided herein can be from any source, such as identified as naturally occurring in plants, or synthetic, such as by mutagenizing SEQ ID NO:1, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 38, 42, 46, 50, 54, 58, 85 or 87 - 92, for example to produce a coding sequence having a G / C content more like that of a naturally occurring gene from a particular plant. The naturally occurring sequences can be from any plant or algal species described herein.
[0416] IV. Transformation Constructs
[0417] Vectors for plant transformation or transformation of other host cells or organisms can include, for example, plasmids, cosmids, YACs (yeast artificial chromosomes), BACs (bacterial artificial chromosomes), or any other suitable cloning system, as well as DNA fragments thereof. Thus, when the terms "vector" or "expression vector" are used, they include all of the above types of vectors and nucleic acid sequences isolated therefrom. It is expected that using cloning systems with large insertion capacities will allow the introduction of large DNA sequences containing more than one selected gene. According to the present disclosure, this can be used to introduce genes corresponding to an entire biosynthetic pathway into plants. The introduction of these sequences can be facilitated by using bacterial or yeast artificial chromosomes (BACs or YACs, respectively), or even plant artificial chromosomes. For example, Hamilton et al. disclosed the use of BACs for Agrobacterium-mediated transformation (Proc. Natl. Acad. Sci. USA 93:9975-9979, 1996).
[0418] Expression cassettes isolated from these vectors are particularly useful for transformation. Of course, the DNA fragments used to transform plant cells will generally contain cDNAs, genes, or multiple genes that are desired to be introduced into and expressed in the host cell. As needed, these DNA fragments can further include structures such as the desired promoters, enhancers, polylinkers, terminators, or even regulatory genes. The DNA fragments or genes selected for introduction into the cell will generally encode proteins expressed in the resulting recombinant cell, producing a screenable or selectable trait and / or conferring an improved phenotype on the resulting transgenic plant. However, this may not always be the case, and the present disclosure also encompasses transgenic plants incorporating non-expressing transgenes. As previously mentioned, in addition to plant cells, the host cells in certain aspects of the present disclosure can be bacterial cells, such as Escherichia coli or Agrobacterium tumefaciens, yeast cells, fungi, algae, or cyanobacterial cells. Those skilled in the art know the genetic elements that must be present on the vector for successful transformation, selection, and propagation of the host cell containing the sequence of interest. The components that can be included in the vectors used in the present disclosure are as follows.
[0419] A. Promoters and other regulatory elements
[0420] In certain embodiments, the expression cassettes of the present disclosure further comprise one or more promoters, such as one or more nucleotide sequences shown in SEQ ID NO: 60-71, or nucleotide sequences having at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% sequence identity to one or more nucleotide sequences shown in SEQ ID NO: 60-71.
[0421] In addition to the promoter sequences disclosed in the sequence listing, other exemplary promoters for expressing nucleic acid sequences include plant promoters such as the CaMV 35S promoter (Odell et al., Nature 313:810-812, 1985), or other promoters such as CaMV19S ((Lawton et al., Plant Mol. Biol. 9:315-324, 1987), nos (Ebert et al., Proc. Natl. Acad. Sci. USA 84:5745-5749, 1987), Adh (Walker et al., Proc. Natl. Acad. Sci. USA 84:6624-6628, 1987), sucrose synthase (Yang and Russell, Proc. Natl. Acad. Sci. USA 87:4144-4148, 1990), α-tubulin, actin (Wang et al., Mol. Cell Biol. 12:3399-3406, 1992), cab (Sullivan et al., Mol. Gen. Genet. 215:431-440, 1989), PEPCase (Hudspeth and Grula, Plant Mol. Biol. 12:579-589, 1989) or those associated with the R gene complex (Chandler et al., Plant Cell 1:1175-1183, 1989). Tissue-specific promoters such as root cell promoters (Conkling et al., Plant Physiol. 93:1203-1211, 1990) and tissue-specific enhancers are also expected to be useful, such as inducible promoters such as ABA- and swelling-inducible promoters. The PAL2 promoter is particularly useful for the present disclosure (U.S. Patent Application Publication No. 2004 / 0049802, the entire disclosure of which is specifically incorporated herein by reference). In one embodiment of the present disclosure, the native promoter of one or more mogroside pathway genes is used. In some embodiments, the promoter is a strong promoter or a weak promoter.
[0422] The DNA sequence between the transcription start site and the start of the coding sequence, i.e., the untranslated leader sequence, can also affect gene expression. Thus, one may wish to use a specific leader sequence with the transformation constructs of the present disclosure. Leader sequences are expected to include those that contain sequences predicted to direct optimal expression of the linked gene, i.e., consensus leader sequences that include those that can increase or maintain mRNA stability and prevent inappropriate translation initiation. The selection of these sequences is known to those skilled in the art according to the present disclosure. Sequences from genes highly expressed in plants may be desirable.
[0423] It is contemplated that vectors for use in accordance with the present disclosure can be constructed to include the ocs enhancer element. This element was first identified as a 16 bp palindromic enhancer of the octopine synthase (ocs) gene from Agrobacterium (Ellis et al., EMBO J. 6:3203-3208, 1987), and is present in at least 10 other promoters (Bouchez et al., EMBO J. 8:4197-4204, 1989). When enhancer elements (e.g., the ocs element, particularly multiple copies of this element) are applied to plant transformation, the transcriptional level of adjacent promoters can be increased.
[0424] It is contemplated that the mogroside biosynthetic pathway coding sequences can be introduced under the control of a novel promoter or enhancer, etc., or a homologous or tissue-specific promoter or control element. Vectors for tissue-specific targeting of genes in transgenic plants typically include tissue-specific promoters and may also include other tissue-specific control elements such as enhancer sequences. In view of the present disclosure, promoters that direct specific or enhanced expression in certain plant tissues are known to those skilled in the art. These promoters include, for example, the rbcS promoter specific to green tissues; the ocs, nos, and mas promoters that have higher activity in root or wounded leaf tissues.
[0425] B. Terminator
[0426] In certain embodiments, the expression cassette of the present disclosure further comprises one or more terminators, such as one or more nucleotide sequences shown in SEQ ID NO: 72-80, or nucleotide sequences having at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98% or at least 99% sequence identity with one or more nucleotide sequences shown in SEQ ID NO: 72-80.
[0427] Conversion constructs prepared according to the present disclosure generally include 3'-end DNA sequences which serve as signals for terminating transcription and allow polyadenylation of the mRNA produced from the coding sequence operably linked to the promoter. In one embodiment of the present disclosure, the native terminator of the mogroside biosynthetic pathway coding sequence is used. Alternatively, a heterologous 3'-end can enhance the expression of sense or antisense mogroside biosynthetic pathway coding sequences. In addition to the terminator sequences disclosed in the sequence listing, other examples of terminators considered useful herein include those from the nopaline synthase gene (nos 3'-end) of Agrobacterium tumefaciens (Bevan et al., Nucl. Acids Res. 11:369-385, 1983), the terminator of the T7 transcript of the octopine synthase gene of Agrobacterium tumefaciens, and the 3'-ends of the protease inhibitor I or II genes from potato or tomato. Regulatory elements such as the Adh intron (Callis et al., Genes Dev. 1:1183-1200, 1987), the sucrose synthase intron (Vasil et al., Plant Physiol. 91:1575-1579, 1989) or the TMV omega element (Gallie and Kado, Proc. Natl. Acad. Sci. USA 86:129-132, 1989) can be further included if desired.
[0428] C. Transit or signal peptides
[0429] In certain embodiments of the present disclosure, transit or signal sequences can be incorporated into the mogroside biosynthetic pathway coding sequences. Sequences linked to the coding sequence of an expressed gene are referred to as transit sequences (usually into vacuoles, vesicles, plastids and other intracellular organelles) and signal sequences (usually to the endoplasmic reticulum, Golgi apparatus and outside the cell membrane), which are removed from the initial translation product after translation and facilitate the transport of the protein into or through intracellular or extracellular membranes. By facilitating the transport of the protein into and out of intracellular and extracellular compartments, these sequences can increase the accumulation of gene products that protect them from proteolytic degradation. These sequences also allow additional mRNA sequences from highly expressed genes to attach to the coding sequence of the gene. Since mRNA translated by ribosomes is more stable than naked mRNA, the presence of translatable mRNA in front of the gene can increase the overall stability of the mRNA transcript from the gene, thereby increasing the synthesis of the gene product. Since transit and signal sequences are usually removed from the initial translation product after translation, the use of these sequences allows the addition of additional translation sequences that may not appear on the final polypeptide. It is also contemplated that for enhancing the stability of the protein, the targeting of certain proteins may be desirable (U.S. Patent No. 5,545,818, incorporated herein by reference in its entirety).
[0430] Alternatively, vectors can be constructed and used to intracellularly target specific gene products in transgenic plant cells or direct proteins to the extracellular environment. This is typically accomplished by ligating a DNA sequence encoding a transit or signal peptide sequence to the coding sequence of a specific gene. The resulting transit or signal peptide will transport the protein to a specific intracellular or extracellular destination, respectively, and will then be removed post-translationally.
[0431] D. Marker Genes
[0432] The ability to identify transformants can be provided or enhanced by using selectable or screenable marker proteins. A "marker gene" is a gene that confers a unique phenotype on cells expressing the marker protein, thus allowing such transformed cells to be distinguished from cells that do not have the marker. Such genes can encode selectable or screenable markers, depending on whether the marker confers a trait that can be "selected" by a person skilled in the art by chemical means, i.e., by using a selection agent (e.g., herbicide, antibiotic, etc.), or whether it is merely a trait that can be identified by a person skilled in the art by observation or testing, i.e., by "screening" (e.g., green fluorescent protein). In addition to the marker genes disclosed in the sequence listing, many additional examples of suitable marker proteins are known in the art and can be used in the practice of the present disclosure.
[0433] The terms "selectable" or "screenable" marker also include genes encoding "secretable markers", the secretion of which can be detected as a means of identifying or selecting transformed cells. Examples include markers for secretable antigens that can be identified by antibody interaction, or even secretable enzymes that can be detected by their catalytic activity. Secretable proteins fall into many categories, including small diffusible proteins that can be detected, for example, by ELISA; small active enzymes that can be detected in extracellular solutions (e.g., α - amylase, β - lactamase, phosphinothricin acetyltransferase); and proteins that are inserted or trapped in the cell wall (e.g., proteins including leader sequences found in expression units such as extensin or tobacco PR S).
[0434] Many selectable marker coding regions are known and available for use in the present disclosure, including but not limited to neo (Potrykus et al., Mol. Gen. Genet. 199:169-177, 1985), which confers kanamycin resistance and can be selected with kanamycin, G418, paromomycin, etc.; bar, which confers bialaphos or phosphinothricin resistance; a mutant EPSP synthase protein that confers glyphosate resistance; nitrilase such as bxn from Klebsiella ozaenae, which confers resistance to bromoxynil (Stalker et al., J. Biol. Chem. 263:6310-6314, 1988); mutant acetolactate synthase (ALS), which confers resistance to imidazolinones, sulfonylureas or other ALS-inhibiting chemicals (European Patent Application 154,204, 1985); methotrexate-resistant DHFR (Thillet et al., J. Biol. Chem. 263:12500-12508, 1988), bromoxynil dehalogenase that confers resistance to the herbicide bromoxynil; or a mutant anthranilate synthase that confers resistance to 5-methyltryptophan, or a sequence that confers resistance to dicamba.
[0435] Exemplary embodiments of selectable markers that can be used to select transformants in the system are those encoding phosphinothricin acetyltransferase, such as the bar gene from Streptomyces hygroscopicus or the pat gene from Streptomyces viridochromogenes. Phosphinothricin acetyltransferase (PAT) inactivates the active ingredient in the herbicides bialaphos and phosphinothricin (PPT). PPT inhibits glutamine synthetase, causing rapid accumulation of ammonia and cell death.
[0436] Useful selectable markers include the β-glucuronidase (GUS) or uidA gene, which encodes an enzyme known for various chromogenic substrates; the R-locus gene, which encodes a product that regulates the production of anthocyanin pigments (red) in plant tissues; the β-lactamase gene (Sutcliffe, Proc. Natl. Acad. Sci. USA 75:3737-3741, 1978), which encodes an enzyme known for various chromogenic substrates (e.g., PADAC, a chromogenic cephalosporin); the xylE gene (Zukowsky et al., Proc. Natl. Acad. Sci. USA 80:1101-1105, 1983), which encodes a catechol dioxygenase capable of converting the chromogenic catechol; the α-amylase gene (Ikuta et al., Biotechnology 8:241-242, 1990); the tyrosinase gene (Katz et al., J. Gen. Microbiol. 129:2703-2714, 1983), which encodes an enzyme capable of oxidizing tyrosine to DOPA and dopaquinone, which in turn condense to form the easily detectable compound melanin; the β-galactosidase gene, which encodes an enzyme in the presence of chromogenic substrates; the luciferase (lux) gene (Ow et al., Science 234:856-859, 1986), which allows bioluminescence detection; the aequorin gene (Prasher et al., Biochem. Biophys. Res. Commun. 126:1259-1268, 1985), which can be used for calcium-sensitive bioluminescence detection; or a gene encoding green fluorescent protein (GFP; Sheen et al., Plant J. 8:777-784, 1995; Haseloff et al., Proc. Natl. Acad. Sci. USA 94:2122-2127, 1997; Reichel et al., Proc. Natl. Acad. Sci. USA 93:5888-5893, 1996; WO 97 / 41228) is also considered a useful reporter gene. The expression of green fluorescent protein can be visualized as fluorescence after irradiation with light of a specific wavelength in cells or plants.
[0437] E. Additional agronomic traits
[0438] In certain embodiments, one or more additional agronomically beneficial traits are engineered into the transgenic plants or organisms of the present disclosure. A "trait" refers to a physiological, morphological, biochemical, or physical characteristic of a plant or organism or of a particular plant material or cell. In some cases, the trait is visible to the human eye, such as seed or plant size, or can be measured by biochemical techniques, such as detecting the protein, starch, or oil content of a seed or leaf, or by observing a metabolic or physiological process, such as measuring carbon dioxide uptake, or by observing the expression level of one or more genes, such as by using northern analysis, RT-PCR, microarray gene expression assays, or reporter gene expression systems, or by agricultural observations such as stress tolerance, yield, or pathogen tolerance. However, any technique can be used to measure the amount, relative level, or difference of any selected compound or macromolecule in a transgenic plant.
[0439] "Trait modification" refers to a detectable difference in the characteristics of a plant or organism that expresses or ectopically expresses a polynucleotide or polypeptide relative to a plant or organism that does not express or ectopically expresses the polynucleotide or polypeptide (e.g., a wild-type or other control plant or organism). In some cases, trait modification can be quantitatively evaluated. For example, compared to a wild-type or other control plant or organism, trait modification can result in an increase or decrease in the observed trait (difference) of at least about 2%, at least 5% difference, at least about 10% difference, at least about 20% difference, at least about 30%, at least about 50%, at least about 70%, or at least about 100%, or even greater differences. Natural variation is known to exist in modified traits. Thus, the observed trait modification results in a change in the normal distribution of the trait in the plant or organism compared to the distribution observed in a wild-type plant or organism.
[0440] Trait modifications of particular interest in the plants of the present disclosure include those to seeds (e.g., embryo or endosperm), fruits, roots, flowers, leaves, stems, branches, seedlings, etc., including: enhanced tolerance to environmental conditions (including freezing, cold, heat, drought, water saturation, radiation, and ozone); improved tolerance to microbial, fungal, or viral diseases; improved tolerance to pest infestations including insects, nematodes, mollusks, parasitic higher plants, etc.; reduced herbicide sensitivity or increased herbicide tolerance, e.g., increased glyphosate or dicamba tolerance; improved heavy metal tolerance or enhanced ability to absorb heavy metals; improved growth under poor light conditions (e.g., low light and / or short day), or altered expression levels of target genes. Other phenotypes that can be modified relate to the production of plant metabolites such as changes in the production of paclitaxel, tocopherols, tocotrienols, sterols, phytosterols, vitamins, wax monomers, antioxidants, amino acids, lignin, cellulose, tannins, prenyl lipids (such as chlorophyll and carotenoids), glucosinolates, and terpenoids, enhanced or constitutively altered protein or oil production (especially in seeds), or modified sugar (insoluble or soluble) and / or starch composition. Physical plant characteristics that can be modified include cell development (e.g., number of trichomes), fruit and seed size and number, yield of plant parts (e.g., stems, leaves, inflorescences, and roots), seed stability during storage, characteristics of seed pods (e.g., sensitivity to breaking), root hair length and number, internode distance, or seed coat quality. Plant growth characteristics that can be modified include growth rate, seed germination rate, vigor of plants and seedlings, leaf and flower senescence, male sterility, apomixis, flowering time, flower abscission, nitrogen uptake rate, osmotic sensitivity to soluble sugar concentration, biomass, or transpiration characteristics, as well as plant architectural characteristics such as apical dominance, branching pattern, number of organs, organ characteristics, organ shape, or size. Additionally, the amount of natural sugars can be reduced, and color can be reduced or removed.
[0441] V. Gene Editing
[0442] One method of generating the transgenic plants of the present disclosure is by genomic modification using site-specific integration or genome editing. Targeted modification of the plant genome by using genome editing methods can be used to generate improved plant lines by modifying the plant genomic DNA. As used herein, "site-directed integration" refers to genome editing methods capable of targeting the insertion of one or more nucleic acids of interest into the plant genome. Suitable methods for altering wild-type DNA sequences or pre-existing transgenic sequences or inserting DNA into the plant genome at a predetermined chromosomal locus include any methods known in the art. Exemplary methods include the use of sequence-specific nucleases such as zinc finger nucleases, engineered or native meganucleases, TALE-endonucleases, or RNA-guided endonucleases (e.g., clustered regularly interspaced short palindromic repeats (CRISPR) / Cas9 system, CRISPR / Cpf1 system, CRISPR / CasX system, CRISPR / CasY system, or CRISPR / Cascade system). Some embodiments relate to methods of genome editing by introducing precise base pair modifications into the plant genome by using single-stranded oligonucleotides. Genome editing methods for modifying, deleting, or inserting nucleic acid sequences into genomic DNA are known in the art.
[0443] In certain embodiments, the present disclosure provides for modifying or replacing existing coding sequences within the plant genome, such as existing transgenic insertions, with sequences encoding different proteins or expression cassettes comprising such proteins. Some embodiments relate to the use of known genome editing methods such as zinc finger nucleases, engineered or native meganucleases, TALE-endonucleases, or RNA-guided endonucleases (e.g., clustered regularly interspaced short palindromic repeats (CRISPR) / Cas9 system, CRISPR / Cpf1 system, CRISPR / CasX system, CRISPR / CasY system, or CRISPR / Cascade system).
[0444] Accordingly, some embodiments can relate to recombinant DNA constructs that contain an expression cassette encoding a site-specific nuclease and optionally any associated proteins for genome modification. These nuclease expression cassettes can be present as donor templates for template editing in the same molecule or vector. Several methods for site-directed integration are known in the art, including different sequence-specific nucleases (or proteins or guide RNAs or complexes of both) that cleave genomic DNA to generate double-strand breaks (DSBs) or nicks at desired genomic sites or loci. As understood in the art, during the repair of DSBs or nicks introduced by nucleases, donor template DNA, transgenes, or expression cassettes can be integrated into the genome at the site of the DSB or nick. The presence of homologous arms in the DNA to be integrated can facilitate the reception and targeting of the inserted sequence into the plant genome by homologous recombination during repair, although the insertion event can occur by non-homologous end joining (NHEJ). As used herein, the term "double-strand break inducer" refers to any reagent that can induce a double-strand break (DSB) in a DNA molecule. In some embodiments, the double-strand break inducer is a site-specific genome modification enzyme.
[0445] As used herein, the term "site-specific genome modification enzyme" refers to any enzyme capable of modifying a nucleotide sequence in a sequence-specific manner. In some embodiments, the site-specific genome modification enzyme modifies the genome by inducing a single-strand break. In some embodiments, the site-specific genome modification enzyme modifies the genome by inducing a double-strand break. In some embodiments, the site-specific genome modification enzyme comprises a cytidine deaminase. In some embodiments, the site-specific genome modification enzyme comprises an adenine deaminase. Site-specific genome modification enzymes include endonucleases, recombinases, transposases, deaminases, helicases, and any combination thereof. In some embodiments, the site-specific genome modification enzyme is a sequence-specific nuclease.
[0446] In one aspect, the endonuclease is selected from the group consisting of meganucleases, zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), Argonaute (non-limiting examples of Argonaute proteins include Thermus thermophilus Argonaute (TtAgo), Pyrococcus furiosus Argonaute (PfAgo), and Natronobacterium gregoryi Argonaute (NgAgo)), RNA-guided nucleases such as CRISPR-associated nucleases (non-limiting examples of CRISPR-associated nucleases include, but are not limited to, Cas1, Cas1B, Cas2, Cas3, Cas4, Cas5, Cas6, Cas7, Cas8, Cas9 (also known as Csn1 and Csx12), Cas10, Csy1, Csy2, Csy3, Cse1, Cse2, Csc1, Csc2, Csa5, Csn2, Csm2, Csm3, Csm4, Csm5, Csm6, Cmr1, Cmr3, Cmr4, Cmr5, Cmr6, Csb1, Csb2, Csb3, Csx17, Csx14, Csx10, Csx16, CsaX, Csx3, Csx1, Csx15, Csf1, Csf2, Csf3, Csf4, Cpf1, CasX, CasY, homologs thereof, or modified versions thereof).
[0447] In some embodiments, the site-specific genome modification enzyme is a recombinase. Non-limiting examples of recombinases include tyrosine recombinases associated with DNA recognition motifs, which are selected from the group consisting of Cre recombinase, Gin recombinase, Flp recombinase, and Tnp1 recombinase. In one aspect, Cre recombinase or Gin recombinase is tethered to a zinc finger DNA-binding domain, or a TALE DNA-binding domain, or a Cas9 nuclease. In another aspect, serine recombinases associated with DNA recognition motifs are selected from the group consisting of PhiC31 integrase, R4 integrase, and TP-901 integrase. In yet another aspect, DNA transposases associated with the DNA-binding domains provided herein are selected from the group consisting of TALE-piggyBa and TALE-mutants.
[0448] By introducing a DNA of interest and the disclosed site-specific genome modification enzyme, any DNA of interest provided herein can be integrated into a target site of a chromosomal sequence. Any method provided herein can utilize any site-specific genome modification enzyme disclosed herein.
[0449] VI. Antisense and RNAi Constructs
[0450] Antisense and RNAi treatments represent one way to alter the activity of genes in the mogroside biosynthetic pathway according to the present disclosure (e.g., by downregulating genes or transcription factors that inhibit the expression of genes in the mogroside biosynthetic pathway).
[0451] Techniques for RNAi are well known in the art and are described, for example, in Lehner et al. (Brief Funct. Genomic Proteomic 3:68 - 83, 2004) and Downward (BMJ 328:1245 - 1248, 2004). This technique is based on the fact that double-stranded RNA can direct the degradation of messenger RNA having a sequence complementary to one or the other strand (Fire et al., Nature 391:806 - 811, 1998). Thus, by expressing a specific coding sequence in both the sense and antisense directions, as a fragment or longer portion of the corresponding coding sequence, the expression of that coding sequence can be downregulated.
[0452] Antisense (and in some aspects RNAi) methods take advantage of the fact that nucleic acids tend to pair with "complementary" sequences. Complementary means that a polynucleotide is a polynucleotide capable of base pairing according to the standard Watson-Crick complementary rules. That is, the larger purine will pair with the smaller pyrimidine base to form combinations where guanine pairs with cytosine (G:C) and in the case of DNA thymine pairs with adenine (A:T) or in the case of RNA thymine pairs with uracil (A:U). The inclusion of less common bases such as inosine, 5-methylcytosine, 6-methyladenine, hypoxanthine, and other bases in the hybridizing sequences does not interfere with pairing.
[0453] Targeting double-stranded (ds) DNA with a polynucleotide results in triple helix formation; targeting RNA results in double helix formation. When introduced into target cells, antisense oligonucleotides specifically bind to their target polynucleotides and interfere with transcription, RNA processing, transport, translation, and / or stability. Antisense and RNAi constructs, or DNA encoding such RNA, can be used to inhibit gene transcription or translation or both in vitro or in vivo, such as within a host plant cell. In certain embodiments of the present disclosure, such oligonucleotides can comprise any unique portion of the nucleic acid sequences provided herein. In certain embodiments of the present disclosure, such sequences comprise at least 18, 20, 25, 30, 50, 75, or 100 or more contiguous nucleic acids of the nucleic acid sequence of interest and / or its complementary sequence, which can be in the sense and / or antisense direction. By including sequences in both the sense and antisense directions, increased inhibition of the corresponding coding sequence can be achieved.
[0454] Constructs can be designed that are complementary to all or part of the promoter and other control regions, exons, introns, or even exon-intron boundaries of a gene. The most effective constructs are expected to include regions complementary to intron / exon splice junctions. Thus, one embodiment is proposed to include constructs complementary to regions within 50-200 bases of an intron-exon splice junction. It has been observed that some exon sequences can be included in the construct without severely affecting its target selectivity. The amount of exon material included will vary depending on the specific exon and intron sequences used. Whether too much exon DNA is included can be easily tested simply by testing the construct in vitro to determine whether normal cell function is affected or whether the expression of the relevant gene with the complementary sequence is affected.
[0455] As described above, "complementary" or "antisense" refers to polynucleotide sequences that are substantially complementary over their entire length and have very few base mismatches. For example, when sequences of 15 bases in length have complementary nucleotides at 13 or 14 positions, they can be said to be complementary. Naturally, completely complementary sequences will be sequences that are completely complementary over their entire length and have no base mismatches. Other sequences with lower degrees of homology are also expected. For example, RNAi or antisense constructs can be designed that have limited regions of high homology but also contain non-homologous regions (e.g., ribozymes; see above). Methods for selecting and designing sequences that produce RNAi are well known in the art (e.g., Reynolds et al., Nat. Biotechnol. 22:326-330, 2004). These molecules, although having less than 50% homology, will bind to the target sequence under appropriate conditions.
[0456] It may be advantageous to combine portions of genomic DNA with cDNA or synthetic sequences to generate specific constructs. For example, genomic clones can be used when introns are required in the final construct. cDNA or synthetic polynucleotides can provide more convenient restriction sites for the remainder of the construct and will thus be used for the rest of the sequence. Constructs for generating RNAi can also contain tandem repeats of subsequences that exhibit gene regulatory activity.
[0457] VII. Transformation
[0458] In some embodiments, the transgenic plants of the present disclosure are produced by transforming selected natural plants with one or more expression cassettes disclosed herein. Natural plants before transformation do not naturally produce all of the mogrosanol / mogroside pathway enzymes, nor do they produce non-natural mogrosanol and mogroside compounds. Although natural plants can produce one or more enzymes capable of producing mogrosanol precursors or mogrosanol, these plants do not naturally produce non-natural mogrosides. In certain embodiments, the natural plants selected for transformation include wild-type, or untransformed, or non-transformed watermelons, which do not naturally produce detectable amounts of mogrosanol or mogroside compounds. Other plants that can be transformed with one or more expression cassettes disclosed herein include, but are not limited to, cantaloupe, honeydew melon, winter melon, casaba melon, Persian melon, citron melon, musk melon, honeydew melon, crenshaw melon, Christmas melon, fairy melon, caravelle melon, hami melon, rock melon, golden Langkawi melon, Korean melon, saticoy melon, Galia melon, gyokuro melon, gold medal melon, ten melon, new century melon, banana melon, yubari king melon, sugar melon, tiger melon, climbing melon, horned melon, cucamelon, casabanana melon, melon), ginseng fruit, pineapple melon, camouflage melon, golden loofah, bitter melon, charentaismelon, crane melon, arrow melon, honey melon, rambutan melon, autumn melon, quick melon, cucumber, tomato, lettuce, spinach, rice, oats, corn, sorghum, bitter apple (Citrullus colocynthis), pumpkin, beet, tobacco, miscanthus, bush cherry, peach, nectarine, apricot, radish, plum, sour cherry, apple, pear, sweet cherry, citrus, zucchini, pea, turnip or Nicotiana benthamiana plant. Mogroside compounds can be isolated from any part of the transformed plant, including but not limited to fruit (juice or skin), leaves, roots, seeds or flowers.
[0459] Suitable methods for the transformation of plants or other cells of the present disclosure are considered to practically include any method that can introduce DNA into cells, such as by direct delivery of DNA, for example, by PEG-mediated protoplast transformation (Omirulleh et al., Plant. Mol. Biol. 21:414-428, 1993), by desiccation / inhibition-mediated DNA uptake (Potrykus et al., Mol. Gen. Genet. 199:169-177, 1985), by electroporation (U.S. Patent No. 5,384,253, which is hereby incorporated by reference in its entirety), by agitation with silicon carbide fibers (U.S. Patent Nos. 5,302,523 and 5,464,765, which are hereby incorporated by reference in their entireties), by Agrobacterium-mediated transformation (U.S. Patent No. 5,591,616 and U.S. Patent No. 5,563,055; both of which are hereby incorporated by reference in their entireties), and by acceleration of DNA-coated particles (U.S. Patent No. 5,550,318; U.S. Patent No. 5,538,877; and U.S. Patent No. 5,538,880; each of which is hereby incorporated by reference in its entirety), etc. By applying these techniques, cells of almost any plant species can be transiently or stably transformed, and these cells can be developed into transgenic plants.
[0460] A. Agrobacterium-mediated transformation
[0461] Agrobacterium-mediated transfer is a widely applicable system for introducing genes into plant cells because DNA can be introduced into whole plant tissues, thus bypassing the need to regenerate whole plants from protoplasts. The introduction of DNA into plant cells using Agrobacterium-mediated plant integration vectors is well known in the art. See, for example, Frale et al. (Proc. Natl. Acad. Sci. USA 80:4803-4807, 1985), and U.S. Patent No. 5,563,055, which is hereby incorporated by reference in its entirety.
[0462] Agrobacterium-mediated transformation is most effective in dicotyledonous plants and is an efficient method for transforming dicotyledonous plants (including Arabidopsis, tobacco, tomato, alfalfa, and potato). In fact, although Agrobacterium-mediated transformation has been routinely used for dicotyledonous plants for many years, it has only recently become applicable to monocotyledonous plants. Advances in Agrobacterium-mediated transformation technology now allow the technique to be applied to almost all monocotyledonous plants. For example, Agrobacterium-mediated transformation has now been applied to rice (Hiei et al., Plant Mol. Biol. 35:205-218, 1997; U.S. Patent No. 5,591,616, which is hereby incorporated by reference in its entirety), wheat and barley (McCormac et al., Mol. Biotechnol. 9:155-159, 1998), alfalfa, and maize (Ishida et al., Nat. Biotechnol. 14:745-750, 1996). Similarly, Agrobacterium-mediated transformation has also been shown to be effective in Miscanthus.
[0463] Modern Agrobacterium transformation vectors are able to replicate in E. coli. E. coli as well as Agrobacterium allow for convenient manipulation. In addition, recent technological advances in vectors for Agrobacterium-mediated gene transfer have improved the arrangement of genes and restriction sites in the vector to facilitate the construction of vectors capable of expressing a variety of polypeptide-encoding genes. The vectors have convenient multiple cloning regions flanked by a promoter and a polyadenylation site for direct expression of the inserted polypeptide-encoding gene and are suitable for the purposes of the present invention. Additionally, Agrobacterium containing armed and disarmed Ti genes can be used for transformation. This is the method of choice in those plant lines in which Agrobacterium-mediated transformation is effective because of the ease and well-defined nature of its gene transfer.
[0464] B. Electroporation
[0465] For transformation by electroporation, friable tissues such as suspensions of cells or embryogenic callus can be used, or immature embryos or other organized tissues can be transformed directly. In this technique, the technician partially degrades the cell wall of the selected cells by exposing the selected cells to a pectin-degrading enzyme (pectin lyase) or by mechanically damaging them in a controlled manner. Examples of some species that have been transformed by electroporation of intact cells include maize (U.S. Patent No. 5,384,253, which is hereby incorporated by reference in its entirety; Rhodes et al., Methods Mol. Biol. 55:121-131, 1995; D’Halluin et al., Plant Cell 4:1495-1505, 1992), wheat (Zhou et al., Plant Cell Rep. 12:612-616, 1993), tomato (Tsukada et al., Plant Cell Physiol. 30:599-603, 1989), soybean (Christou et al., Proc. Natl. Acad. Sci. USA 84:3962-3966, 1987), and tobacco (Riggs and Bates, Proc. Natl. Acad. Sci. USA 83:5602-5606, 1986).
[0466] Electroporation-mediated transformation of plants can also be performed using protoplasts (Bates, Mol. Biotechnol. 2:135-145, 1994; Lazzeri, Methods Mol. Biol. 49:95-106, 1995). For example, the generation of transgenic soybean plants by electroporation of cotyledon-derived protoplasts is described in WO 9217598 (which is hereby incorporated by reference in particular). Other examples of species for which protoplast transformation has been described include barley (Lazzeri, ibid.), sorghum (Battraw et al., Theor. Appl. Genet. 82:161-168, 1991), maize (Rhodes et al., Science 240:204-207, 1988), wheat (He et al., Plant Cell Rep. 14:192-196, 1994), and tomato (Tsukada, ibid.).
[0467] C. Particle Bombardment
[0468] Another method of delivering a transforming DNA fragment to a plant cell according to the present disclosure is microprojectile bombardment (U.S. Patent No. 5,550,318; U.S. Patent No. 5,538,880; U.S. Patent No. 5,610,042; and PCT Application WO94 / 09699, each of which is incorporated herein by reference in its entirety). In this method, particles can be coated with nucleic acid and delivered into cells by a propulsive force. Exemplary particles include those composed of tungsten, platinum, and commonly gold. It is contemplated that in some cases, precipitation of DNA onto the metal particles is not necessary for delivering DNA to recipient cells using microprojectile bombardment. However, it is contemplated that the particles can contain DNA rather than being coated with DNA. Thus, it is proposed that DNA-coated particles can increase the level of DNA delivery by particle bombardment, but they are not essential per se.
[0469] For bombardment, the cells in suspension are concentrated on a filter or solid medium. Alternatively, immature embryos or other target cells can be arranged on solid medium. The cells to be bombarded are located at an appropriate distance below the stopping plate of the macroprojectile.
[0470] An exemplary embodiment of a method for accelerating the delivery of DNA into plant cells is the biolistic particle delivery system, which can be used to propel particles coated with DNA or cells through a screen (e.g., a stainless steel or Nytex screen) onto the surface of a filter covered with suspension-cultured monocotyledonous plant cells. The screen disperses the particles so that they are not delivered to the recipient cells as large aggregates. The microprojectile bombardment technique is widely applicable and can be used to transform almost any plant species. Examples of species that have been transformed by microprojectile bombardment include monocotyledonous species such as maize (PCT application WO95 / 06128), barley (Ritala et al., Plant Mol. Biol. 24:317-325, 1994; Hensgens et al., Plant Mol. Biol. 22:1101-1127, 1993), wheat (U.S. Patent No. 5,563,055, which is hereby incorporated by reference in its entirety), rice (Hensgens et al., ibid.), oats (Torbet et al., Crop Science 38:226-231, 1998), rye (Hensgens et al., ibid.), sugarcane (Bower et al., Plant J. 2:409-416, 1992), and sorghum (Casas et al., Proc. Natl. Acad. Sci. USA 90:11212-11216, 1993; Hagio et al., Plant Cell Rep. 10:260-264, 1991); and many dicotyledonous plants, including tobacco (Tomes et al., Plant Mol. Biol. 14:261-268, 1990), soybean (U.S. Patent No. 5,322,783, which is hereby incorporated by reference in its entirety), sunflower (Knittel et al., Plant Cell Rep. 14:81-86, 1994), peanut ((Singsit et al., Transgenic Res. 6:169-176, 1997), cotton (McCabe and Martinell, Nat. Biotechnol. 11:596-598, 1993), tomato (Van Eck et al., Plant Cell. Rep. 14:299-304, 1995), Miscanthus (Richards et al., Plant Cell Rep. 20:48-54, 2001), and common bean (U.S. Patent No. 5,563,055, which is hereby incorporated by reference in its entirety).
[0471] D. Other transformation methods
[0472] Transformation of protoplasts can be achieved using methods based on calcium phosphate precipitation, polyethylene glycol treatment, electroporation, and combinations of these treatments (see, e.g., Potrykus et al., supra; Omirulleh et al., supra). The application of these systems in different plant lines depends on the ability to regenerate that particular plant line from protoplasts. Exemplary methods for regenerating cereals from protoplasts have been described (Toriyama et al., Nat. Biotechnol. 6:1072-1074, 1988; Abdullah et al., Nat. Biotechnol. 4:1087-1090, 1986; Omirulleh et al., supra, and U.S. Patent No. 5,508,184; each incorporated herein by reference in its entirety). Examples of transformation using direct uptake by cereal protoplasts include transformation of rice (Ghosh-Biswas et al., J. Biotechnol. 32:1-10, 1994), sorghum (Battraw et al., supra), barley (Lazzeri, supra), oats, and maize (Omirulleh et al., supra).
[0473] To transform plant lines that cannot be successfully regenerated from protoplasts, other methods for introducing DNA into intact cells or tissues can be utilized. For example, regeneration of cereals from immature embryos or explants can be carried out as described (Vasil, supra). In addition, silicon carbide fiber-mediated transformation can be used with or without protoplasting (Kaeppler et al., Theor. Appl. Genet. 84:560-566, 1992; U.S. Patent No. 5,563,055, incorporated herein by reference in its entirety). Transformation with this technique is accomplished by agitating silicon carbide fibers and cells in a DNA solution. When the cells are punctured, the DNA enters passively. This technique has been successfully used, for example, for monocot cereal maize (PCT application WO95 / 06128, incorporated herein by reference in its entirety) and rice (Nagatani et al., Biotechnol. Tech. 11:471-473, 1997).
[0474] E. Tissue Culture
[0475] Tissue culture can be used in certain transformation techniques to prepare cells for transformation and to regenerate plants therefrom. Maintenance of tissue culture requires the use of culture media and a controlled environment. A "culture medium" refers to a variety of nutrient mixtures used to grow cells in vitro, i.e., outside of a whole, living organism. Culture media are typically suspensions of the various components (salts, amino acids, growth regulators, sugars, buffers) required for the growth of most cell types. However, each specific cell type requires a specific range of proportions of components for growth, and an even more specific range of formulations for optimal growth. The cell growth rate will also vary with cultures initiated with a series of media that permit the growth of that cell type.
[0476] Nutrient media are prepared as liquids, but this can be solidified by adding the liquid to materials that can provide a solid support. Agar is most commonly used for this purpose. AGAR, and are specific types of solid supports suitable for culturing plant cells in tissue culture.
[0477] Some cell types will grow and divide in liquid suspension or on solid media. As disclosed herein, plant cells will grow in suspension or on solid media, but regenerating plants from suspension cultures generally requires transfer from liquid media to solid media at certain points in development. The type and degree of cell differentiation in a culture are affected not only by the type of medium and environment (e.g., pH) used, but also by whether the medium is solid or liquid.
[0478] Tissues that can be grown in culture include meristematic cells, type I, II, and III callus, immature embryos, and gamete cells such as microspores, pollen, sperm, and egg cells. Type I, II, and III callus can be initiated from tissue sources including, but not limited to, immature embryos, shoot apical meristems of seedlings, roots, leaves, microspores, etc. Those cells that are capable of proliferating as callus are also recipient cells for genetic transformation.
[0479] Somatic cells come in various types. Embryogenic cells are an example of somatic cells that can be induced to regenerate plants by embryogenesis. Non-embryogenic cells are those that do not typically respond in this way. Certain techniques can be used to enrich for recipient cells in a cell population. For example, development of type II callus, followed by manual selection and culturing of friable embryogenic tissue, generally results in cell enrichment. Artificial selection techniques that can be used to select target cells can include, for example, assessing cell morphology and differentiation, or various physical or biological means can be used. Cryopreservation is also a possible method for selecting recipient cells.
[0480] Artificially selecting recipient cells, for example by selecting embryogenic cells from the surface of type II callus, is a method that can be used to attempt to enrich specific cells prior to culturing (whether on solid medium or in suspension).
[0481] When used, the cultured cells can be grown on a solid support or in the form of a liquid suspension. In either case, nutrients can be provided to the cells in the form of a culture medium, and the environmental conditions can be controlled. There are many types of tissue culture media composed of various amino acids, salts, sugars, growth regulators, and vitamins. Most of the media employed in the practice of the present disclosure will have some similar components, but depending on the specific application contemplated, their composition and proportions can vary. For example, various cell types typically grow in more than one type of medium, but will exhibit different growth rates and different morphologies depending on the growth medium. In some media, the cells survive but do not divide. Various types of media suitable for culturing plant cells have been described previously. Examples of such media include, but are not limited to, the N6 medium described by Chu et al., (Sci. Sin. [Peking] 18:659 - 668, 1975) and the MS medium (Murashige and Skoog, Physiol. Plant 15:473 - 479, 1962).
[0482] VIII. Production and Characterization of Stably Transformed Plants
[0483] After delivering the foreign DNA into the recipient cells, the next step generally involves identifying the transformed cells for further culturing and plant regeneration. To improve the ability to identify transformants, it may be desirable to use a selectable or screenable marker gene in conjunction with the transformation vector prepared according to the present disclosure. In this case, the population of potentially transformed cells will typically be analyzed by exposing the cells to one or more selection agents, or the desired marker gene trait of the cells will be screened.
[0484] A. Selection
[0485] It is believed that in any given study, DNA is only introduced into a small percentage of the target cells. To provide an effective system for identifying those cells that have received the DNA and integrated it into their genome, a method for selecting those cells that are stably transformed can be employed. An exemplary embodiment of such a method is to introduce a marker gene into the host cell that confers resistance to some common inhibitors such as antibiotics or herbicides. Examples of antibiotics that can be used include the aminoglycoside antibiotics neomycin, kanamycin, and paromomycin, or the antibiotic hygromycin. Aminoglycoside phosphotransferase enzymes such as neomycin phosphotransferase II (NPT II) or NPT I confer resistance to aminoglycoside antibiotics, while hygromycin phosphotransferase confers resistance to hygromycin.
[0486] The cells that may be transformed are then exposed to a selection agent. Among the surviving cell population, typically those are the cells that have integrated the resistance-conferring gene and express it at a sufficient level to allow cell survival. The cells can be further tested to confirm the stable integration of the foreign DNA.
[0487] One herbicide that constitutes the required selection agent is the broad-spectrum herbicide bialaphos. Bialaphos is a tripeptide antibiotic produced by Streptomyces hygroscopicus and consists of phosphinothricin (PPT), an analogue of L-glutamic acid, and two L-alanine residues. After removal of the L-alanine residues by intracellular peptidases, PPT is released and is a potent inhibitor of glutamine synthetase (GS), a key enzyme involved in ammonia assimilation and nitrogen metabolism (Ogawa et al., Sci. Rep. Meiji Seika 13:42-48, 1973). Synthetic PPT (the active ingredient in the herbicide Liberty TM ) is also effective as a selection agent. Inhibition of GS in plants by PPT leads to rapid accumulation of ammonia and death of plant cells.
[0488] The organisms that produce bialaphos and other Streptomyces species also synthesize the enzyme phosphinothricin acetyltransferase (PAT), which is encoded by the bar gene in Streptomyces hygroscopicus and the pat gene in Streptomyces viridochromogenes. The use of the herbicide resistance gene encoding phosphinothricin acetyltransferase (PAT) is described in DE3642829A, in which the gene was isolated from Streptomyces viridochromogenes. In organisms of bacterial origin, the enzyme acetylates the free amino group of PPT to prevent autotoxicity (Thompson et al., EMBO J. 6:2519-2523, 1987). The bar gene has been cloned (Thompson et al., ibid.) and expressed in transgenic tobacco, tomato, potato (De Block et al., Plant Physiol. 91:694-701, 1989), Brassica (De block et al., plantphysiol. 91:694-701, 1989) and maize (U.S. Patent No. 5,550,318, which is incorporated herein by reference in its entirety).
[0489] Another example of a herbicide that can be used to select transformed cell lines in the practice of the present disclosure is the broad-spectrum herbicide glyphosate. Glyphosate inhibits the action of the enzyme EPSPS, which is active in the aromatic amino acid biosynthesis pathway. Inhibition of this enzyme results in starvation for the amino acids phenylalanine, tyrosine, and tryptophan and their derived secondary metabolites. U.S. Patent No. 4,535,060 (incorporated herein by reference in its entirety) describes the isolation of EPSPS mutants that confer glyphosate resistance to the aroA gene of Salmonella typhimurium for EPSPS. The EPSPS gene was cloned from maize and mutations similar to those found in the glyphosate-resistant aroA gene were introduced in vitro. Mutant genes encoding glyphosate-resistant EPSPS enzymes are described, for example, in International Patent WO97 / 4103.
[0490] To use the bar-bialaphos or EPSPS-glyphosate selection system, the transformed tissue is cultured on non-selective medium for 0 - 28 days and then transferred to medium containing 1 - 3 mg / l bialaphos or 1 - 3 mM glyphosate, as appropriate. While the range of 1 - 3 mg / l bialaphos or 1 - 3 mM glyphosate may be beneficial, it is proposed that a range of 0.1 - 50 mg / l bialaphos or 0.1 - 50 mM glyphosate would be useful.
[0491] An example of a selectable marker trait is luciferase. In the presence of the substrate luciferin, cells expressing luciferase emit light that can be detected on photographic or X-ray film, in a photometer (or liquid scintillation counter), by a device that enhances night vision, or by a highly sensitive video camera such as a photon-counting camera. These assays are non-destructive and the transformed cells can be further cultured after identification. A photon-counting camera is particularly valuable because it allows the identification of specific cells or cell populations expressing luciferase and their manipulation in real time. Another selectable marker that can be used in a similar manner is the gene encoding green fluorescent protein.
[0492] B. Regeneration and Seed Production
[0493] Cells that survive exposure to a selection agent, or cells that score positive in a screening assay, can be cultured in a medium that supports plant regeneration. In one exemplary embodiment, MS and N6 media can be modified by including other substances such as growth regulators. One such growth regulator is dicamba or 2,4-D. However, other growth regulators can be used, including NAA, NAA + 2,4-D, or picloram. It has been found that medium modifications in these and similar ways promote cell growth at specific developmental stages. Tissue can be maintained on a basal medium containing a growth regulator until there is sufficient tissue available to initiate plant regeneration, or after repeated rounds of manual selection, until the morphology of the tissue is suitable for regeneration (at least 2 weeks), and then transferred to a medium that aids in embryoid maturation. The cultures are transferred to this medium every 2 weeks. Shoot development will indicate the time to transfer to a medium lacking growth regulators.
[0494] Then, the transformed cells identified by selection or screening and cultured in a suitable medium that supports regeneration are matured into plants. The developing seedlings are transferred to a soilless plant growth mixture and hardened, for example, in an environmentally controlled chamber (e.g., at approximately 85% relative humidity, 600 ppm CO 2 and 25 - 250 microeinsteins m 2 s -1 light). The plants can be matured in a growth chamber or greenhouse. Depending on the initial tissue, plants can be regenerated approximately 6 weeks to 10 months after identification of the transformants. During the regeneration process, the cells are grown on solid medium in tissue culture containers. Exemplary embodiments of such containers are petri dishes and Plant Cons. The regenerated plants can be grown at approximately 19 to 28 °C. After the regenerated plants reach the shoot and root development stages, they can be transferred to a greenhouse for further growth and testing.
[0495] Due to seed development arrest and premature senescence of the plants, seeds on transformed plants may occasionally require embryo rescue. To rescue the developing embryos, they are excised from surface-sterilized seeds 10 - 20 days after pollination and cultured. An embodiment of the medium used for culturing at this stage contains MS salts, 2% sucrose, and 5.5 g / l agarose. In embryo rescue, large embryos (defined as having a length greater than 3 mm) germinate directly on a suitable medium. Embryos smaller than this length can be cultured on a medium containing the above components and 10 -5 M abscisic acid for 1 week and then transferred to a medium lacking growth regulators for germination.
[0496] C. Characterization
[0497] To confirm the presence of foreign DNA or "transgenes" in regenerated plants, a variety of assays can be performed. Such assays include, for example, "molecular biology" assays such as Southern and Northern blotting and PCR TM ; "biochemical" assays, such as detecting the presence of protein products by immunological means (ELISA and Western blotting) or by enzyme function; plant part assays, such as leaf or root assays; and also by analyzing the phenotype of the entire regenerated plant.
[0498] D. DNA integration, RNA expression, and inheritance
[0499] Using techniques well known to those skilled in the art, genomic DNA can be isolated from cell lines or any plant part to assay for the presence of foreign genes. Note that complete sequences are not always present, presumably due to rearrangements or deletions of sequences in the cell. The presence of DNA elements introduced by the methods of the present disclosure can be assayed, for example, by polymerase chain reaction (PCR TM ). Using this technique, discrete fragments of DNA are amplified and detected by gel electrophoresis. This type of analysis allows determination of whether a gene is present in a stable transformant, but does not prove that the introduced gene has integrated into the host cell genome. However, typically the DNA has integrated into the genomes of all transformants, and the presence of the gene is confirmed by PCR TM analysis. In addition, it is generally not possible to use PCR TM techniques to determine whether a transformant has foreign genes introduced at different sites in the genome, i.e., whether the transformant has an independent origin. It is expected that using PCR TM techniques, it may be possible to clone fragments of host genomic DNA adjacent to the introduced gene.
[0500] Positive evidence of DNA integration into the host genome and the independent nature of the transformant can be determined using Southern hybridization techniques. Using this technique, specific DNA sequences introduced into the host genome and flanking host DNA sequences can be identified. Thus, the Southern hybridization pattern of a given transformant serves as an identifying characteristic of that transformant. In addition, the presence of the introduced gene in high molecular weight DNA can be confirmed by Southern hybridization, i.e., it is confirmed that the introduced gene has integrated into the host cell genome. Southern hybridization techniques provide the information obtained using PCR TM such as the presence of a gene, but also prove integration into the genome and characterize each individual transformant.
[0501] It is expected that using dot or slot blot hybridization techniques (which are modifications of Southern hybridization techniques), information of the same origin as that obtained by PCR TM such as the presence of a gene can be obtained.
[0502] PCR TM Both PCR and Southern hybridization techniques can be used to confirm the transmission of transgenes to offspring. In most cases, the characteristic Southern hybridization pattern of a given transformant segregates in the offspring as one or more Mendelian genes (Spencer1 et al., 1992), indicating stable inheritance of the transgene.
[0503] Although DNA analysis techniques can be performed using DNA isolated from any part of the plant, RNA is only expressed in specific cell or tissue types, and thus RNA for analysis needs to be prepared from these tissues. PCR TM techniques can also be used to detect and quantify the RNA produced by the introduced gene. In this application of PCR TM it is first necessary to reverse transcribe the RNA into DNA using an enzyme such as reverse transcriptase, and then amplify the DNA by using conventional PCR TM techniques. In most cases, although PCR TM techniques are useful, they cannot prove the integrity of the RNA product. Further information on the nature of the RNA product can be obtained by Northern blotting. This technique will demonstrate the presence of the RNA species and give information on the integrity of that RNA. Dot or slot blot Northern hybridization can also be used to determine the presence of the RNA species. These techniques are modifications of Northern blotting and will only demonstrate the presence or absence of the RNA species.
[0504] E. Gene expression
[0505] Although Southern blotting and PCR TM can be used to detect the gene in question, they do not provide information on whether the corresponding protein is expressed. Expression can be evaluated by specifically identifying the protein product of the introduced gene or by assessing the phenotypic changes caused by its expression.
[0506] Assays for the production and identification of specific proteins can utilize the physicochemical, structural, functional, or other properties of the protein. Unique physicochemical or structural properties allow the separation and identification of proteins by electrophoretic methods (such as native or denaturing gel electrophoresis or isoelectric focusing) or by chromatographic techniques (such as ion exchange or gel exclusion chromatography). The unique structure of individual proteins provides the opportunity to detect their presence using specific antibodies in the form of assays such as ELISA. Combinations of methods with even greater specificity can be used, such as western blotting, where antibodies are used to localize individual gene products that have been separated by electrophoretic techniques. Additional techniques can be used to absolutely confirm the identity of the target product, such as evaluation by amino acid sequencing after purification. Although these are the most commonly used, other procedures can alternatively be used.
[0507] The assay procedures can also be used to identify the expression of a protein by its functionality, especially the ability of an enzyme to catalyze a specific chemical reaction involving specific substrates and products. These reactions can then be followed by physical or chemical steps to provide and quantify the loss of substrate or the production of reaction products. The examples are as variable as the enzyme to be analyzed and can include, for example, determining PAT enzyme activity after production of radiolabeled acetylated phosphinothricin from phosphinothricin and 14 C-acetyl coenzyme A, or determining anthranilate synthase activity after loss of fluorescence of anthranilate.
[0508] The expression of a gene product is often determined by assessing the phenotypic consequences of its expression. These assays can also take many forms, including but not limited to analyzing changes in the chemical composition, morphology, or physiological properties of a plant. The chemical composition can be altered by the expression of an enzyme that modifies the amino acid composition or a storage protein and can be detected by amino acid analysis, or by an enzyme that alters the amount of starch, which can be analyzed by near-infrared reflectance spectroscopy. Morphological changes can include greater height or thicker stems. Most commonly, changes in the response of a plant or plant part to an applied treatment are evaluated under carefully controlled conditions called a bioassay.
[0509] IX. Sweeteners and consumables containing mogrosides
[0510] In some embodiments, the present disclosure generally relates to a sweetener or sweetening composition comprising mogrosides and / or their metabolites or derivatives, wherein the sweetener or sweetening composition is derived from a transgenic plant that produces and contains non-natural mogrol / mogrosides.

The resulting ingredients containing mogrosides can be in any form, including but not limited to powders, liquids, syrups, concentrates or extracts. Additionally, in some embodiments, fruits or vegetables containing intact mogrosides are consumable.
[0514] In certain embodiments, the sweetener is obtained from the leaves of a transgenic plant prepared according to the present disclosure.

In one embodiment, when present in a sweetening composition, such as a food, other consumable, or beverage, the natural high-intensity sweetener is present in the sweetener composition in an amount effective to provide a concentration of from about 0.5 ppm to about 2500 ppm, from about 1.0 ppm to about 2000 ppm, from about 5 ppm to about 1500 ppm, from about 10 ppm to about 1000 ppm, or from about 25 ppm to about 500 ppm. In one embodiment, when present in a sweetening composition such as a food, other consumable, or beverage, the natural high-intensity sweetener is present in the sweetener composition in an amount effective to provide a concentration greater than about 0.1 ppm, about 0.5 ppm, about 1.0 ppm, about 2.5 ppm, about 5.0 ppm, about 10 ppm, about 20 ppm, about 25 ppm, about 50 ppm, about 75 ppm, about 100 ppm, about 200 ppm, about 500 ppm, about 1000 ppm, about 2000 ppm, or about 300 ppm.
[0519] In other embodiments, the additional sweetener can be a chemically or enzymatically modified natural high-intensity sweetener. Modified natural high-intensity sweeteners include glycosylated natural high-intensity sweeteners, such as glucosyl-, galactosyl- or fructosyl-derivatives containing 1-50 glycoside residues. Glycosylated natural high-intensity sweeteners can be prepared by enzymatic transglycosylation reactions catalyzed by various enzymes having transglycosylase activity.
[0520] When the sweetener composition contains more than one sweetener, these sweeteners can exhibit a synergistic effect when combined and have improved flavor and temporal characteristics compared to each individual sweetener alone. As used herein, the term "temporal characteristics" of a composition refers to the intensity of sweetness perceived by a person over time when tasting the composition. The term "flavor profile" or "taste profile" as commonly used herein refers to the intensity of the various flavor / taste attributes of a sweetener or sweetened composition. Exemplary flavor / taste attributes are sweetness intensity, bitterness intensity, saltiness intensity, licorice intensity, cooling intensity, and licorice intensity. Methods for determining the flavor profile of a given sweetener or sweetened composition are known in the art. The term "synergistic" or "synergistic effect" refers to an effect (e.g., flavor, temporal characteristics) achieved with a combination of two or more sweeteners that is greater than the sum of the effects produced by using the individual sweeteners alone or separately. Advantageously, this synergistic effect between two or more sweeteners allows for the use of a smaller dose of one or both sweeteners or provides a greater effect at the same amount. The amount or degree of the synergistic effect can vary.
[0521] The amount of sucrose in the reference solution can be described in degrees Brix (Bx). One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as a weight percentage (% w / w) (strictly speaking, by mass). In one embodiment, the sweetener composition contains one or more of the sweetener compounds disclosed herein, which, when present in the sweetened composition, are effective in providing a sweetness equivalent of at least about 5 degrees Brix, such as at least about 5, at least about 6, at least about 7, at least about 8, at least about 9, at least about 10, at least about 11, at least about 12, at least about 13, at least about 14, or at least about 15 or more degrees Brix.
[0522] The sweetness of non-sucrose sweeteners can also be measured by determining the sucrose equivalent of the non-sucrose sweetener relative to a sucrose reference. Typically, a tasting panel is trained to detect the sweetness of a reference sucrose solution containing 1-15% sucrose (w / v). Other non-sucrose sweeteners are then tasted at a series of dilutions to determine the concentration of the non-sucrose sweetener that is as sweet as a given percentage of sucrose reference. For example, if a 1% solution of a sweetener is as sweet as a 10% solution of sucrose, the potency of the sweetener is said to be 10 times that of sucrose.
[0523] Sweetener compositions can be customized to provide a desired calorie content. For example, sweetener compositions can be "full calorie" such that they impart a desired sweetness when added to a sweetenable composition (e.g., a food, other consumable, or beverage) and have about 120 calories per 8 ounce serving. Alternatively, sweetener compositions can be "medium calorie" such that they impart a desired sweetness when added to a sweetenable composition and have less than about 60 calories per 8 ounce serving. Or, sweetener compositions can be "low calorie" such that they impart a desired sweetness when added to a sweetenable composition and have less than 40 calories per 8 ounce serving. In other embodiments, sweetener compositions can be "zero calorie" such that they impart a desired sweetness when added to a sweetenable composition and have less than 5 calories per 8 ounce serving.
[0524] The sweetener compositions disclosed herein can optionally include one or more additional additives. In some embodiments, the sweetener composition contains additives including, but not limited to, carbohydrates, polyols, amino acids and their corresponding salts, polyamino acids and their corresponding salts, sugar acids and their corresponding salts, nucleotides, organic acids, inorganic acids, organic salts (including organic acid salts and organic base salts), inorganic salts, bitter compounds, flavorants and flavor components, astringent compounds, proteins or protein hydrolysates, surfactants, emulsifiers, bulking agents, gums, antioxidants, colorants, flavonoids, alcohols, polymers, and combinations thereof. In some embodiments, the additives are used to improve the temporal and flavor characteristics of the sweetener to provide a sweetener composition having a taste similar to sucrose. The sweetenable composition can contain one or more functional ingredients as detailed above. Functional ingredients include, but are not limited to, vitamins, minerals, antioxidants, preservatives, glucosamine, polyphenols, and combinations thereof. Any suitable functional ingredient described herein can be used.
[0525] Compared to existing monk fruit products, the mogroside sweeteners disclosed in the present invention have beneficial environmental impacts. Compared to, for example, harvesting and processing only in China and transporting globally to food companies, the monk fruit sweeteners disclosed in the present invention can be produced locally, resulting in less transportation and fewer food miles. The disclosed monk fruit sweeteners of the present invention also require minimal processing as the monk fruit sweeteners are readily obtainable in the disclosed transgenic plants or organisms compared to, for example, factory processing of monk fruit sweeteners in China.
[0526] X. Sweetenable Compositions
[0527] The sweetener compositions disclosed herein can be incorporated into any known edible material (referred to herein as "sweetenable compositions"), such as pharmaceutical compositions, edible gel mixtures and compositions, dental compositions, foods (candies, condiments, chewing gums, cereal compositions, baked goods, dairy products, and tabletop sweetener compositions), beverages, and beverage products.
[0528] The sweetenable compositions disclosed herein include beverages, i.e., ready-to-drink liquid formulations, beverage concentrates, etc. In certain embodiments, a beverage concentrate is prepared with an initial volume of liquid (such as water), to which additional ingredients are added. A full-strength beverage composition can be formed from the beverage concentrate by adding a greater volume of liquid (such as water) to the concentrate.
[0529] In embodiments using a mogroside-containing filled juice concentrate (about 80% mogroside V, about 15% 11-oxo-mogroside V, and about 5% mogroside III A1) as the sweetenable composition, studies have shown it to be the sweetest and purest natural sweetener. The mogroside-containing filled juice concentrate disclosed herein can be produced from consumer-friendly fruits that can be sustainably grown locally, is the only sweetener that achieves high sugar reduction while maintaining a 100% juice label, and is an affordable drop-in solution. The filled juice can be used as a single strength or concentrated to deliver pure sweetness at various inclusion levels. When used in various formulation inclusions, the filled juice mogroside concentration can deliver an equivalent of ~10 sucrose equivalent values (SEV).
[0530] In addition to concentration, other juice parameters can also be readily altered, resulting in different sweetener products. For example, the natural sugars in a fruit (such as watermelon) can be partially or fully removed, the juice color and / or flavor can be minimized or removed, the pulp can be removed as is typically done, or fully or partially retained in a puree, and the acidity can be reduced, or a combination of one or more of these parameters can be altered.

As disclosed herein, a "hybrid" plant to provide a plant line having one or more added transgenes relative to a starting plant line is defined as a technique in which the starting line is hybridized with a donor plant line containing the transgene of the present disclosure, resulting in the introduction of the transgene of the present disclosure into the plant line. To achieve this, for example, the following steps can be performed:
[0570] (a) Plant seeds of a first parental plant (starting line) and a second parental plant (donor plant line containing the transgene of the present disclosure);
[0571] (b) Growing the seeds of the first and second parental plants into plants with flowers;
[0572] (c) Pollinating the flowers from the first parental plant with pollen from the second parental plant; and
[0573] (d) Harvesting the seeds produced on the parental plant with fertilized flowers.
[0574] Backcrossing is defined herein as a process that includes the following steps:
[0575] (a) Crossing a plant of a first genotype containing a desired gene, DNA sequence, or element with a plant of a second genotype lacking the desired gene, DNA sequence, or element;
[0576] (b) Selecting one or more progeny plants containing the desired gene, DNA sequence, or element;
[0577] (c) Crossing the progeny plant with a plant of the second genotype; and
[0578] (d) Repeating steps (b) and (c) in order to transfer the desired DNA sequence from the plant of the first genotype to the plant of the second genotype.
[0579] The introgression of a DNA element into a plant genotype is defined as the result of a backcross conversion process. The plant genotype into which the DNA sequence is introgressed can be referred to as the backcross-converted genotype, line, inbred, or hybrid. Similarly, a plant genotype lacking the desired DNA sequence can be referred to as the non-converted genotype, line, inbred, or hybrid.

In certain embodiments of the present disclosure, it may be necessary to introduce the transformation construct into the host cell in the form of an expression cassette.
[0605] Transformed cell: A cell whose DNA complement has been altered by the introduction of an exogenous DNA molecule into the cell.
[0606] Transgene: A DNA fragment that has been integrated into the host genome or is capable of autonomous replication in a host cell and is capable of causing the expression of one or more coding sequences. Exemplary transgenes will provide a new phenotype to the host cell or a plant regenerated therefrom relative to the corresponding non-transformed cell or plant. A transgene can be introduced directly into a plant by genetic transformation, or it can be inherited from any previous plant transformed with the DNA fragment.
[0607] Transgenic plant: A plant or any subsequent generation of progeny plants derived therefrom, wherein the DNA of the plant or its progeny contains an introduced exogenous DNA fragment that does not naturally occur in non-transgenic plants of the same strain.
