AI Technical Summary
Current methods for producing docosapentaenoic acid (DPA) in recombinant cells are inefficient, with most organisms unable to produce oils with DPA levels above 1-2%, and there is a need for alternative sources of long-chain polyunsaturated fatty acids (LC-PUFAs) due to the decline of fish-derived sources.
The production of lipids containing DPA is enhanced by engineering plants and microbial cells to incorporate specific enzymes such as ω3-desaturases and elongases, resulting in DPA levels between 7% and 35% of the total fatty acid content, primarily esterified at the sn-2 position of triacylglycerol (TAG) molecules.
This approach significantly increases DPA production efficiency, achieving higher DPA levels in plant and microbial lipids without co-production of DHA, providing a sustainable alternative to fish-derived LC-PUFAs.

Abstract
Description
[Technical Field]
[0001] The present invention relates to a lipid containing docosapentaenoic acid obtained from plant cells or microbial cells, and and methods for producing and using said lipids. [Background technology]
[0002] Omega-3 long-chain polyunsaturated fatty acids (LC-PUFAs) are important for human and animal health. These fatty acids are now widely recognized as compounds. Linoleic acid (LA, 18:2ω6), both of which are considered essential dietary fatty acids Alternatively, it can be obtained by conversion of alpha-linolenic acid (ALA, 18:3ω3) fatty acid. Humans and many other vertebrates are unable to convert LA or ALA obtained from plant sources to C22. However, this conversion reaction occurs very slowly. Instead of the 4:1 or less ratio of omega-6:omega-3 fatty acids that is commonly used, at least 90% polyvalent Eating an unbalanced diet with omega-6 polyunsaturated fatty acids (PUFA) (Trautwein, 2001). Eicosapentaenoic acid (EPA) for humans , 20:5ω3), docosapentaenoic acid (DPA), and docosahexaenoic acid (DHA, Most readily available dietary sources of LC-PUFAs, such as 22:6ω3, come from fish or fish oil. Therefore, health experts recommend that the human diet contain fish containing significant levels of LC-PUFAs. Increasingly, fish-derived LC-PUFA oils are being used in foods containing e.g. It is used in foods and infant formula. However, the decline of the global and national fishing industry Because of this, there is a need for alternative sources of these beneficial health-promoting oils.
[0003] In contrast to animals, flowering plants produce polyunsaturated fatty acids with chains longer than 18 carbons. In particular, crops and horticultural plants, along with other angiosperms, do not have the ability to synthesize 5-ALA. The derived EPA, docosapentaenoic acid (DPA, 22:5ω3) and DHA They lack the enzymes necessary to synthesize long-chain omega-3 fatty acids. Galls produce substantial amounts of LC-PUFAs and therefore provide an alternative source of these compounds. It is the engineering of the crops we provide. Summary of the Invention
[0004] LC-PUFA biosynthetic pathway The biosynthesis of LC-PUFAs in organisms such as microalgae, mosses, and fungi usually involves a series of acids. The EPA-producing enzymes in these organisms are desaturated and elongated (Figure 1). The most common pathways are Δ6-desaturation, Δ6-elongation, and Δ5-desaturation. The most common pathway is the Δ6-desaturation pathway, while the less common pathway is Δ9-elongation, Δ8-desaturation, and Δ5-desaturation (Δ9-desaturation pathway) These successive desaturation and elongation reactions are shown in the upper left part of Figure 1. The resulting omega-6 fatty acid substrate LA(ω6) is shown in the formula or EPA in the lower right of Figure 1. It can start with either the ω3 substrate ALA(ω3). If the initial Δ6-desaturation reaction is If the LC-PUFA product of the series of three enzymes occurs on the ω-6 substrate LA, it is likely that the ω-6 lipid LC-PUFA synthesis is arachidonic acid (ARA, 20:4ω6). The conversion of EPA to ω3-desaturase is shown as the Δ17-desaturase step in Figure 1. ω3-desaturase can be used to convert ω6 fatty acids to ω3 fatty acids. Several members of the Milli family can act on a variety of substrates ranging from LA to ARA Plant ω3-desaturases often perform the Δ15-desaturation reaction of LA to ALA. whereas fungal and yeast ω3-desaturases specifically catalyze the conversion of ARA to E It may be specific for the Δ17-desaturation reaction to PA (Pereira et al., 200 4a; Zank et al., 2005). Converts a wide range of ω6 substrates to their corresponding ω3 products. Several reports suggest that there may be nonspecific ω3-desaturases that can (Zhang et al., 2008).
[0005] The conversion of EPA to DHA in these organisms occurs via a Δ5-elongation reaction of EPA. This produces DPA, which is then converted to DHA by a Δ4-desaturation reaction (Figure 1). In contrast, mammals catalyze DPA DH through three separate reactions independent of Δ4-desaturase. A is converted to the so-called "Sprecher" pathway (Sprecher et al., 1995).
[0006] Plants, mosses, microalgae, and nematodes (Caenorhabditis elegans The front-end desaturases commonly found in lower animals, such as phosphatidylcholinesterases (PDEs), are It predominantly accepts phosphorus (PC) substrates at the sn-2 position and esterified fatty acid substrates. These desaturases are involved in the synthesis of acyl-PC, lipid-linked, and front-end desaturases. In contrast, the frontal lobes of higher animals are known as the frontal lobes (Domergue et al., 2003). Generally, acetyl-CoA desaturases prefer acyl-C, where the fatty acid substrate is bound to CoA rather than PC. Some microalgae, such as Desaturas, accept oA as a substrate (Domergue et al., 2005). One plant desaturase and one plant desaturase use fatty acid substrates esterified with CoA. It is known that (Table 2).
[0007] Each PUFA elongation reaction consists of four steps catalyzed by a multicomponent protein complex: As a result of the condensation reaction, 2C units are added from malonyl-CoA to the fatty acid, forming β-ketoacids. This is then reduced by NADPH and then dehydrated. This intermediate is finally reduced twice to give the elongated fatty acid. The condensation steps of these four reactions are generally substrate specific, while the other steps are not. In fact, the natural plant elongation mechanism is thought to be a natural mechanism for the elongation of non-natural PUFA substrates. Although the efficiency of the natural plant elongation machinery may be low, PUFA-specific condensing enzymes (usually called "elongation enzymes") This means that the PUFA provided by the introduction of the enzyme can be elongated. In 2007, the identification and characterization of yeast elongation cycle dehydratases was reported. expressed (Denic and Weissman, 2007).
[0008] While elongation reactions occur on substrates in the acyl-CoA pool, in plants, mosses, and PUFA desaturation in plants and microalgae preferentially targets fatty acid substrates in the acyl-PC pool. The transfer of acyl-CoA fatty acids to the PC carrier occurs naturally as a result of lysophosphatidylcholine While the conversion of acyl-PC molecules occurs via phospholipid acyltransferase (LPCAT), The transfer of fatty acids to the CoA carrier occurs via phospholipase (PLA) (Singh et al. , 2005).
[0009] Engineering the production of LC-PUFAs Most LC-PUFA metabolic engineering has been carried out using the aerobic Δ6-desaturation / elongation pathway. In tobacco, the biosynthesis of gamma-linolenic acid (GLA, 18:3ω6) is initiated by cyanobacteria. Cyanobacterium Synechocystis s) was first reported in 1996 (Reddy and T Homas, 1996). More recently, GLA has been found in safflower (GLA 73% in seed oil). %, WO2006 / 127789) and soybean (GLA 28%; Sato et al., 2004) The production of LC-PUFAs such as EPA and DHA has been shown to reduce the associated The number of saturation and elongation steps makes the engineering more complex. A production was first reported by Qi et al. (2004) and was reported in Isochrysis galbana (Iso chrysis galbana) Δ9-elongase, Euglena gracilis (E Δ8-desaturase from Mortierella gracilis and Mortierella alpi A gene encoding Δ5-desaturase from Mortierella alpina The offspring were introduced into Arabidopsis with yields of up to 3% EPA.

A review of attempts to produce oilseed crops with 0) and Ruiz-Lopez et al. (2012). As shown by Pez et al. (2012), DHA production in transgenic plants However, results to date have not come close to the levels seen with fish oil. Recently, Petrie et al. (2012) reported that Arabidopsis thaliana reported that approximately 15% of DHA is produced in the seeds of P. haliana, and published in WO2013 / 18 5184 reported the production of specific seed oils with between 7% and 20% DHA. However, there have been no reports of producing vegetable oils with more than 20% DHA.
[0011] There have been no reports of DPA production in recombinant cells to significant levels without the concomitant production of DHA. Indeed, the present inventors have not found any publicly available method for producing DPA in recombinant cells without DHA production. I don't know the inspiration or motivation behind it.
[0012] Therefore, LC-PUFAs in recombinant cells, especially those like DPA in the seeds of oilseed plants, There remains a need for more efficient production.

[0211] In an embodiment, the plants of or used in the present invention are grown in a field, preferably in an essentially or at least 1 hectare or 2 hectares in area. It grows in colonies of 1,000, 1,000,000 or 2,000,000 plants. Planting density depends on plant species, plant variety, weather, soil conditions, fertilizer rates and other factors known in the art. For example, rapeseed usually requires 1.2-1.5 acres per hectare. The plants are grown at a planting density of 5 million plants. The plants are harvested and the plants are then fertilized as known in the art. swathing, plucking and / or reaping, and then threshing and / or winnowing the plant material to separate it from the remaining plant parts, which are often in the form of chaff; Alternatively, the seeds may be separated from the corn by a single treatment, e.g., a combine harvester. You can also use a harvester to harvest from plants in the field.
[0212] Plant transformation Transgenic plants were grown according to the method described by A. Slater et al., Plant Biotechnol. ogy-The Genetic Manipulation of Plants,O xford University Press (2003), and P. Christo u and H. Klee, Handbook of Plant Biotechno logy, John Wiley and Sons (2004) These can be produced using techniques known in the art, such as:
[0213] As used herein, "stably transforming," "stably transformed," and and its variants grow in progeny cells during cell division without the need for active selection for their presence. The term "incorporation" refers to the integration of an exogenous nucleic acid molecule into the genome of a cell so that it can be transferred to the cell. Confirmed transformants or their progeny were analyzed by Southern blot or genomic DNA analysis. Any method known in the art, such as in situ hybridization of NA Preferably, plant transformation is carried out as described in the Examples herein. do.
[0214] Agrobacterium-mediated transfer allows for the transient or stable expression of DNA in the genome of plant cells. For integration either in whole plant tissue or plant organs or cells in explants in tissue culture This allows the transfer of DNA into plant cells, making it a widely applicable system for transferring genes into plant cells. The Agrobacterium-mediated plant integration vector is used to introduce DNA into plant cells. The use of vectors involves the use of Agrobacterium or other bacteria capable of transferring DNA into plant cells. These include the floral dip method, which is well known in the art (see, e.g., US517701 0, US5104310, US5004863 or US5159135). The DNA region to be transfected is delimited by border sequences, and the intervening DNA (T-DNA) is usually Furthermore, the T-DNA integration is relatively precise with little retransposition. These plant varieties where Agrobacterium-mediated transformation is efficient are In this context, the ease and defined nature of gene transfer makes it the method of choice. Agrobacterium transformation vectors allow for convenient manipulation as described. It can replicate in E. coli as well as in cereals (Klee et al., In: Plant DNA I nfectious Agents, Hohn and Schell, eds., Sp. ringer-Verlag, New York, pp.179~203(1985)) .
[0215] Acceleration methods that can be used include, for example, particle bombardment. One example of a method for delivering molecules into plant cells is microprojectile bombardment. This method was described by Yang et al. .Particle Bombardment Technology for Gen e Transfer.Oxford Press,Oxford,England(1 994) is outlined. Non-biological particles (microparticle ejecta) are coated with nucleic acid and propelled by the propulsion force. Illustrative particles include those made of tungsten, nickel, platinum, etc. In addition to being an efficient means of reproducibly transforming monocotyledonous plants, A particular advantage of biolistic bombardment is that neither protoplast isolation nor susceptibility to Agrobacterium infection is required. It is unnecessary.
[0216] In another alternative embodiment, the plastids can be stably transformed. The methods disclosed for transformation include the incorporation of selectable markers and the introduction of homologous DNA. and particle gun delivery of DNA targeted to the plastid genome via recombination. (US5,451,513, US5,545,818, US5,877,402, US5 ,932479, and WO99 / 05265).
[0217] Other methods of cell transformation may also be used, including but not limited to direct DNA transfer into pollen. by direct injection of DNA into the reproductive organs of plants or by injecting DNA into the cells of immature embryos. DNA can be introduced into plants by directly injecting the .gamma.- and then rehydrating the desiccated embryos. The following are some of the reasons for this.
[0218] Regeneration of plants from a single plant protoplast transformation or from various transformed explants The methods of growth, development, and cultivation are well known in the art (Weissbach et al., In:Met. hods for Plant Molecular Biology,Academi (C Press, San Diego, Calif., (1988)). The development process involves the selection of transformed cells, the establishment of plantlets, and the normal stages of embryo development. The process typically involves culturing these individualized cells to produce transgenic embryos and seeds. The resulting transgenic rooted shoots are then grown in a suitable plant growth medium such as soil. Cultivate in a medium.
[0219] Development or propagation of plants containing foreign or exogenous genes Regeneration or regeneration of the plant is well known in the art. Preferably, the regenerated plant is transformed with a homologous transformant. Alternatively, pollen from the regenerated plants can be used in agronomical experiments. Conversely, the desired exogenous nucleic acid is hybridized with a plant grown from seeds of a biologically important line. Transgenic plants of the invention are cultivated using methods well known to those skilled in the art. Transgenic plants of the invention containing nucleic acids are cultured using methods well known to those skilled in the art.
[0220] To confirm the presence of the transgene in transgenic cells and plants, Polymerase chain reaction (PCR) amplification or Southern blot analysis is performed using methods known to those skilled in the art. The expression product of the transgene can be isolated by any of a variety of methods, depending on the nature of the product. These can be detected by a variety of methods, including Western blot and enzyme assays. Once the plants are obtained, they can be cultured to produce plant tissues or parts having the desired phenotype. The plant tissue or parts may be harvested and / or the seeds may be collected. Additional plants containing tissues or parts with the desired characteristics may serve as a growth source.
[0221] Transgenic plants produced using Agrobacterium or other transformation methods Typically, a single gene locus is contained on one chromosome. Such transgenic plants are It can be said that the gene is hemizygous. Transgenic plants that are homozygous for the two additional genes, i.e., A homozygous transgenic plant has one gene at the same locus on each chromosome of a chromosome pair. Transgenic plants were obtained by self-pollinating hemizygous transgenic plants and producing several seeds. The desired gene can be obtained by germination of the desired plant material and analysis of the resulting plants for the gene of interest.
[0222] Two different transgenes containing two independently segregating exogenous genes or loci Genetic plants can also be crossed (mating) to produce offspring containing both sets of genes or loci. Self-pollination of suitable F1 progeny results in homozygotes for both the foreign gene or locus. This allows the production of plants that are homozygous. Outcrossing is also considered botanical propagation. Others commonly used for different traits and crops For a description of breeding methods, see Fehr, In:Breeding Methods for C ultivar Development,Wilcox J.ed.,America n Society of Agronomy,Madison Wis.(1987) can be seen in.
[0223] Enhanced and stabilized expression of exogenous RNA levels Silencing suppressors In embodiments, the plant cell, plant or plant part contains a silencing suppressor protein. The recombinant vector contains an exogenous polynucleotide encoding a protein.
[0224] Post-transcriptional gene silencing (PTGS) is a process that degrades cellular and viral mRNAs. Target S and stably or transiently transform with foreign (heterologous) or endogenous DNA. occurs in the introduced plant or fungus and accumulates RNA molecules with sequence similarity to the introduced nucleic acid. It is a nucleotide sequence-specific host defense mechanism that can result in a reduction of
[0225] Co-expression of a transgene of interest and a silencing suppressor results in the expression of a silencing suppressor from the transgene. It has been widely thought that this would increase the levels of RNA present in the cell that is transcribed. While this has proven true for cells in vitro, significant side effects have been observed in many whole-cell transplants. More specifically, Mallory et al. (2002), Cha pman et al. (2004), Chen et al. (2004), Dunoyer et al. (2004), Z (2006), Lewsey et al. (2007), and Meng et al. (2008) As described above, plant-expressed silencing suppressors are generally expressed under constitutive promoters. Often, they are phenotypically abnormal to the extent that they are not useful for commercial production.
[0226] Recently, RNA molecule levels have been increased and / or silenced. By restricting expression of the suppressor to the seeds of the plant or its parts, the It has been found that the compound can be stabilized over a long period of time (WO2010 / 057246). When silencing suppressor proteins, or SSPs, are specifically Expression products from different transgenes in plant cells over repeated generations of transformed plants In some embodiments, S is a polypeptide that can be expressed in plant cells to enhance the organism's level. SPs are viral silencing suppressors or their mutants. Virus silencing suppressors are known in the art and include, but are not limited to: , P19, V2, P38, Pe-Po and RPV-P0. The virus silencing suppressor is an amino acid sequence having the sequence of SEQ ID NO: 38, Active fragments or fragments at least 50% identical to SEQ ID NO: 38 and silencing sequences It contains an amino acid sequence that has repressor activity.
[0227] As used herein, "stable expression," "stably expressed," "stably expressed" " and variations thereof refer to RNA molecules encoding silencing suppressors. When compared to isogenic plants that do not contain the native polynucleotide, repeated generations, e.g. For example, the progeny may be grown for at least three generations, at least five generations, or at least ten generations. However, this term does not apply to repeated generations. Therefore, there is some loss of RNA molecules when compared to the previous generation, e.g. The possibility of losses of 10% or more is not excluded.
[0228] The suppressor may be selected from any source, e.g., plant, viral, mammalian, etc. The viruses from which the suppressor can be obtained and the suppressors from each particular virus can be selected. List of repressor proteins (e.g., B2, P14, etc.) or coding region designations See WO2010 / 057246. Multiple copies of the suppressor may be used. Multiple suppressors may be used together (e.g., in series).
[0229] RNA molecule Essentially, any RNA that is desired to be expressed in plant seeds can be silenced. The encoded polypeptide can be co-expressed with a suppressor. may be related to the metabolism of compounds, nutrients, or proteins, peptides, fatty acids, Fats, waxes, oils, starches, sugars, carbohydrates, fragrances, odors, toxins, Rotenoids, hormones, polymers, flavonoids, storage proteins, phenolic acids alkaloids, lignins, tannins, cellulose, glycoproteins, glycolipids, Others, preferably, may be involved in the biosynthesis of TAG or the synthesis of aggregates.
[0230] In particular examples, the plants produced are Brassica, e.g., rapeseed or castor bean. Barley, safflower, flax, cotton, soybean, camelina or corn It increased the levels of enzymes for oil production in plants such as ginger.
[0231] Produced LC-PUFA levels LC-PUFA or LC-PUFAs produced in recombinant cells or plant parts such as seeds The level of a particular LC-PUFA or related LC-PUFA combination is important. PUFAs, such as ω3LC-PUFAs or ω6LC-PUFAs, or VLCs -total fatty acids, which may be PUFAs or other fatty acids that can be determined by methods known in the art The levels may be expressed as a percentage of the dry weight of the material containing the recombinant cells. Percentage of LC-PUFA in a food, e.g., percent of the weight of the seed that is LC-PUFA The levels may be expressed as a percentage of LC-PUFA content, such as % of LC-PUFAs produced in oilseeds. The LC-PUFAs in these foods are more abundant than those in vegetables or grains that are not grown for oil production. The LC-PUFA content is quite high, and both have similar LC-PUFA compositions. However, both may be used as a source of LC-PUFA for human or animal consumption. will be recognized.
[0232] LC-PUFA levels may be determined by any method known in the art. In a preferred method, total lipids are extracted from cells, tissues or organisms and analyzed by gas chromatography. Fatty acids are converted to methyl esters prior to analysis by GC. Such a technique is shown in Example 1. 1. Chromatographic peak positions were used to identify each specific fatty acid. The amount can be determined by the integrated area under each peak. Unless otherwise specified, the percentage of a particular fatty acid in a sample is expressed as a percentage of the total area of the fatty acid in the chromatogram. The percent is determined from the area under the peak for this fatty acid, which is essentially a weight percent. The identity of the fatty acids can be confirmed by GC-MS. Total lipids are determined by the method of the art. The fractions may be separated by techniques known in the art to purify fractions such as the TAG fraction. For example, thin layer chromatography (TLC) can be performed on an analytical scale to identify the lipids of TAG. To determine the acid composition specifically, DAG, acyl-CoA, or other lipids such as phospholipids The TAG can be separated from the fraction.
[0233] In one embodiment, the sum of the fatty acids ARA, EPA, DPA, and DHA in the extracted lipid is between about 21% and about 40% of the total fatty acids in the cell. In a preferred embodiment, the total fatty acids in the extract have less than 1% C20:1. Possible TAGs include fatty acids at the levels indicated herein. The invention also encompasses each possible combination of the defined features.
[0234] The level of LC-PUFA production in a recombinant cell, plant, or plant part, such as a seed, is determined by the method of the present invention. The specificity of one or more produced fatty acids, also referred to herein as "conversion efficiency" or "enzyme efficiency," It may also be expressed as the percent conversion of substrate fatty acids. This parameter is useful for cells, plants, The fatty acid composition of lipids extracted from plant parts or seeds, i.e., one or more substrate fatty acids LC-PUFAs produced as a percentage of the total fatty acids (including all other fatty acids derived from them) The general formula for percent conversion is: 00 x (percentage sum of produced LC-PUFA and all products derived therefrom) / (substrate fatty acid and the percentage sum of all products derived therefrom). Acid (e.g., OA, LA, ALA, SDA, ETA, or EPA) and DP derived from the substrate As a ratio of DPA level to the level of all products including A (total fatty acid content in lipids) This may be expressed as a percentage of the conversion. The conversion percentage or conversion efficiency may be expressed as a percentage of the conversion in a single pathway. It can represent a single enzymatic step, or part or the entire pathway.
[0235] The specific conversion efficiency is calculated herein according to the formula: 1. OA to DPA=100x(DHA%+DPA%) / (OA, LA, GLA, D GLA, ARA, EDA, ALA, SDA, ETrA, ETA, EPA, DPA and DH % sum of A). 2. LA to DPA=100x(DHA%+DPA) / (LA, GLA, DGLA, % Total of ARA, EDA, ALA, SDA, ETrA, ETA, EPA, DPA and DHA sum). 3. ALA to DPA=100x(DHA%+DPA%) / (ALA, SDA, ET (% sum of rA, ETA, EPA, DPA and DHA). 4. EPA to DPA = 100x(DHA%+DPA) / (EPA, DPA and DHA) % sum of A). 5. DPA to DHA (Δ4-desaturase efficiency) = 100X (DHA%) / (D % sum of PA and DHA). 6. Δ12-desaturase efficiency = 100x (LA, GLA, DGLA, ARA, E % Sum of DA, ALA, SDA, ETrA, ETA, EPA, DPA and DHA) / (O A, LA, GLA, DGLA, ARA, EDA, ALA, SDA, ETrA, ETA, E (% sum of PA, DPA and DHA). 7. ω3-desaturase efficiency = 100x (ALA, SDA, ETrA, ETA, EP % total of A, DPA and DHA) / (LA, GLA, DGLA, ARA, EDA, ALA , % sum of SDA, ETrA, ETA, EPA, DPA and DHA). 8. OA to ALA=100x(ALA, SDA, ETrA, ETA, EPA, DP A and DHA % sum) / (OA, LA, GLA, DGLA, ARA, EDA, ALA, (% sum of SDA, ETrA, ETA, EPA, DPA and DHA). 9. Δ6-desaturase efficiency (ω3 substrate ALA) = 100 x (SDA, ETA, E % Sum of PA, DPA and DHA) / (ALA, SDA, ETrA, ETA, EPA, D % of PA and DHA 10. Δ6-elongase efficiency (ω3 substrate SDA) = 100 x (ETA, EPA, D (% Sum of SDA, ETA, EPA, DPA and DHA) / (% Sum of SDA, ETA, EPA, DPA and DHA). 11. Δ5-desaturase efficiency (ω3 substrate ETA) = 100x (EPA, DPA and (% Sum of ETA, EPA, DPA and DHA) / (% Sum of ETA, EPA, DPA and DHA). 12. Δ5-elongase efficiency (ω3 substrate EPA) = 100 x (DPA and DHA) % Sum) / (% Sum of EPA, DPA and DHA).
[0236] The fatty acid composition of the lipids of the present invention, preferably the seed oils, is: total ω6 fatty acids: total ω3 fatty acids or new ω-6 fatty acids: new ω-3 fatty acids, the ω-6 fatty acids in the total fatty acid content It is also characterized by the ratio of omega-3 fatty acids to total omega-6 fatty acids, total omega-3 fatty acids, and new omega-6 fatty acids. The terms fatty acid and new omega-3 fatty acid have the meanings defined herein. from the fatty acid composition of lipids extracted from cells, plants, plant parts or seeds by the method described above, It is desirable to have greater levels of omega-3 than omega-6 fatty acids in lipids, therefore Therefore, an ω6:ω3 ratio of less than 1.0 is preferred. A ratio of 0.0 indicates that no defined ω6 fatty acids are present. A ratio of 0.03 was obtained, indicating the absence of ω3-desaturated fatty acids. ze, in particular Pichia pastoris ω exemplified herein Δ, which has ω3 substrate preference, along with fungal ω3-desaturases such as ω3-desaturase This can be achieved by using 6-desaturase in combination.
[0237] The yield of LC-PUFA per weight of seed was calculated based on the total oil content in the seed and the content of the oil. For example, if the oil content of canola seeds is If about 40% (w / w) and about 12% of the total fatty acid content in the oil is DPA, The DPA content of the seeds is about 4.8% or about 48 mg per gram of seed. In terms of DPA content, canola seeds or Camelina sativa (Camelina s ativa seeds have a DPA content of approximately 84 mg per gram of seed. The invention relates to the cultivation of rapeseed (Brassica napus), mustard (B. juncea), and cea and Camelina sativa plants, and seed gra and at least about 80 mg or at least about 84 mg of DPA per gram from the plant. The seeds are harvested mature seeds after drying (4 to 15% moisture content). The present invention relates to the method of obtaining seeds and extracting oil from the seeds. and a method for obtaining the oil comprising extracting the plant according to the invention, and the use of said oil. Also provided is a method for obtaining seeds comprising harvesting seeds from
[0238] The amount of DPA produced per hectare is also calculated if the seed yield per hectare is already For example, the amount of oil palm oil in Australia is Rapeseed typically produces about 2.5 tonnes of seed per hectare and has an oil content of 40%. The yield of oil is approximately 1000 kg. At 20.1% DPA of total oil, This gives about 200 kg of DPA per hectare. If the oil content is reduced by 50%, This still gives about 100 kg DPA per hectare.
[0239] Evidence to date suggests that several desaturases expressed heterologously in yeast or plants These results suggest that the enzyme has relatively low activity in combination with some elongases. The ability to use the acyl-CoA form of fatty acids as substrates in LC-PUFA synthesis This may be alleviated by providing desaturases with the desired activity, which may be used in recombinant cells, particularly in plants. Particularly beneficial combinations for efficient DPA synthesis are For example, Micromonas pusilla Δ6-desaturase Δ6-desaturases with a preference for ω3 acyl substrates, such as enzymes such as enzymes (SEQ ID NO: 9). or variants thereof having at least 95% amino acid sequence identity, e.g., Pichia pastoris ω3-desaturase (SEQ ID NO: 6) and fungal ω3-desaturases.
[0240] As used herein, the term "essentially free" refers to a composition (e.g., a liquid or or oil) contains almost all of the specified components (e.g., less than about 0.5%, less than about 0.25%, This means that the amount of soluble solids contained in the soluble solids is less than 0.1%, or less than about 0.01%, or completely free of soluble solids. In this context, "essentially free" means that the detection of specific fatty acids (ω6- Cosapentaenoic acid, etc.) were analyzed using gas chromatography as outlined in Example 1. This means that the minute cannot be detected.
[0241] In an embodiment, the extract of the invention (of or used in a process / method of the invention) Extracted lipids, extracted oils, plants or plant parts such as seeds, feed, or the like of the present invention. The composition of all cis-6,9,12,15,18-heneicosapentaenoic acid (n-3 H PA) is not included.
[0242] Oil production Techniques routinely practiced in the art can be used to culture the cells, plants, seeds, etc. of the invention. It can be used to extract, process, and analyze oils produced by plant seeds. is cooked, pressed and extracted to produce crude oil, which is then degummed and refined. Generally, seed crushing techniques are known in the art. For example, oilseeds are sprayed with water to soften them to a suitable moisture content, say 8. It can be increased up to 5%, and the smooth roller is set with a gap of 0.23~0.27mm. Depending on the type of seed, it may not be necessary to add water before grinding. Heat inactivates enzymes, promotes further cell destruction, aggregates oil droplets, and disintegrates protein particles. All of these facilitate the extraction process.
[0243] In an embodiment, the majority of the seed oil is liberated by passing it through a screw press. The cake expelled from the screw press is then passed through a heat tracking column. or solvent extraction with, for example, hexane using a traced column; The crude oil produced by the squeezing operation is poured into a settling tank with a grooved wire drainage top cover. This allows the removal of solids that may have developed in the oil during the pressing operation. The remaining fine solid particles can be removed by passing it through a frame filter. The oil recovered from the can be combined with the clarified oil to produce a blended crude oil.
[0244] Once the solvent is removed from the crude oil, the combined pressed and extracted portions are generally Conventional oil processing methods are followed. As used herein, the term "oil-based oils" refers to oils that are combined with the lipids or oils of the present invention. When used in conjunction, the term "purified" refers to an extracted lipid or oil. This refers to the use of one or more processing steps to increase the purity of the lipid / oil components. The manufacturing process may include one or more of the following steps: degumming, deodorizing, bleaching, drying, and / or separating the extracted oil. However, as used herein, "purified" may include any of the above or all of the above. The term "fatty acid" refers to a compound of the present invention that increases DPA content as a percentage of the total fatty acid content. Does not include interesterification or other processes that alter the fatty acid composition of the lipid or oil. In other words, the fatty acid composition of a refined lipid or oil is different from that of an unrefined lipid or oil. It is essentially the same as Il.
[0245] degumming Degumming is the initial step in oil refining, and its main purpose is to remove approximately 1-2% of the total extracted lipids. The aim is to remove most of the phospholipids from the oil. Addition of about 2% water, usually containing phosphoric acid, to crude oil resulted in the association of trace metals and pigments. Most of the phospholipids are separated. The insoluble material removed is mainly phospholipids and triacylglycerol. It is a mixture of concentrated phosphoric acid and crude seed oil. By adding the phosphatides to the phosphate buffer, degumming is performed and non-hydratable phosphatides are converted to hydratable phosphatides. The gum is then centrifuged to separate the seed oil from the cellulose. Separate from the file.
[0246] Alkali Refining Alkali refining, sometimes called neutralization, is one of the refining methods for processing crude oil. This is usually done after degumming and before bleaching. After degumming, a sufficient amount of alkaline solution is added to remove the color from the seeds. The oil can be treated to titrate out all of the fatty acids and phosphates, thus removing the soaps formed. Suitable alkaline substances include sodium hydroxide, potassium hydroxide, sodium carbonate, Examples include lithium hydroxide, calcium hydroxide, calcium carbonate, and ammonium hydroxide. This method is usually carried out at room temperature and removes the free fatty acid moieties. The separation or soap is removed by extraction into a solvent and the neutralized oil is washed with water. Any excess alkali in the oil may be neutralized with a suitable acid such as hydrochloric acid or sulfuric acid.
[0247] bleaching Decolorization can be achieved in the presence of bleaching earth (0.2-2.0%), in the absence of oxygen, with nitrogen or steam. Heat the oil at 90-120°C for 10-30 minutes by operating under vacuum. This step in oil processing removes unwanted pigments (carotenoids, chlorophyll, etc.). The method is designed to remove oxidative products, microorganisms, etc. It also removes minor metals, sulfur compounds and traces of soap.
[0248] Deodorization Deodorization is carried out by using oil and The seed oil is usually added at a rate of about 0.1 ml / min / 100 ml. This is done by introducing steam into the oil. After about 30 minutes of sparging, the seed oil The oil is then cooled under vacuum. The seed oil is then transferred to a glass container, usually before being stored in a refrigerator. This treatment improves the color of the seed oil and removes any volatiles or residual Removes most of the odorous compounds, including free fatty acids, monoacylglycerols, and oxidation products do.
[0249] Let's take it off Winterization is the process of converting oils and fats into solids (stearins) by crystallization at subambient temperatures. It is sometimes used in the commercial production of oils to separate the crude (sugar) and liquid (olein) fractions. It was first applied to cottonseed oil to produce a solids-free product. It is commonly used to reduce fatty acid content.
[0250] Transesterification As used herein, "transesterification" refers to the transfer of fatty acids within and between TAGs. This refers to the process of transferring a fatty acid to another alcohol to produce an ester. may first involve liberating the fatty acids from the TAG as free fatty acids, or directly Fatty acid esters, preferably fatty acid methyl esters or ethyl esters, can be produced. In the transesterification reaction of TAG with alcohols such as methanol or ethanol, The alkyl group of the alcohol forms an ester bond with the acyl group of the TAG (including DPA). When combined with preparative methods, transesterification can be used to modify the fatty acid composition of lipids. (Marangoni et al., 1995). Transesterification can be achieved by chemical (e.g., strong Either acid or base catalyzed or enzymatic means can be used, the latter of which is to convert the fatty acids of the TAGs can be position-specific (sn-1 / 3 or sn-2 specific) or more specific than others Lipases with selectivity for some fatty acids are used (Speranza et al., 201 2) Fatty acid fractionation, which increases the LC-PUFA concentration in oil, can be performed using techniques such as freeze crystallization, Complexation with urea, molecular distillation, supercritical fluid extraction, countercurrent chromatography This can be done by any of the methods known in the art, such as by precipitation and silver ion complexation. Complexation with urea helps to reduce the saturated and monounsaturated fatty acid levels in the oil. It is the preferred method due to its simplicity and efficiency (Gamez et al., 2003). The TAGs in oils are often hydrolyzed under either acid or base catalyzed conditions. In the form of a fatty acid ester, the resulting alkylated fatty acid is split into its constituent fatty acids. The excess was used to allow separation of the ester from the glycerol produced by lipase. at least 3 moles of alcohol (e.g., ethanol for ethyl esters) One mole of TAG is reacted with the alcohol or methanol for the methyl ester. , these free fatty acids or fatty acid esters, whose fatty acid composition is usually not altered by processing. may be mixed with an ethanolic solution of urea for complexation. Saturated and monounsaturated fats The acid readily forms a complex with urea, crystallizes on cooling, and can be removed by filtration. The non-urea complex fraction is thereby enriched in LC-PUFAs.

The temperature was then increased to 300°C at 5°C / min. ogies ChemStation software (Palo Alto, California, USA) The peaks were quantified using the GC method. The GC results have an error of ±5% of the individual component areas.
[0291] Perform GC-mass spectrometry (GC-MS) analysis on the Finnigan Thermoquest GCQ GC=MS and Finnigan Thermo Electron Corp Both systems were equipped with an on-column injector and a T Hermoquest Xcalibur software (Austin, Texas, USA) Each GC was equipped with a capillary column of the same polarity as the one described above. Mass spectrometry data was used and the retention time data was compared with that obtained by reliable standards and laboratory standards. Individual components were identified by comparing the data. A link analysis was performed.
[0292] RT-PCR conditions 10 pmol (picomoles) of forward primer and 30 pmol of reverse primer, final 400ng (nanograms) of RNA total, including MgSO4 and buffers up to a concentration of 2.5mM A 25 μL volume of Superscribe was prepared using the nucleotide components according to the manufacturer's instructions. The pt III One-Step RT-PCR system (Invitrogen) was used. Reverse transcription PCR (RT-PCR) amplification was routinely performed under the following conditions: typical temperature conditions were 45°C. reverse transcription for one cycle at 94°C for 30 minutes; then for one cycle at 94°C for 2 minutes; Then, 40 cycles of 94°C for 30 seconds, 52°C for 30 seconds, and 70°C for 1 minute; After one cycle of 72°C for 2 minutes, the reaction mixture was cooled to 5°C.
[0293] Determining transgene copy number by digital PCR To determine the copy number of the transgene in the transgenic plants, the following steps were performed: This method was used to verify that plants were transfected with the gene constructs described herein. It should also be possible to determine whether a person is genetically transgenic. Meters of leaf tissue were harvested from each individual plant and placed in collection microtubes (Qia The samples were then freeze-dried for 24-48 hours. A stainless steel ball bearing was added to each dried sample for thawing. The tube was shaken in the Tissuelyser. Extraction buffer (375 μL, 0.1 M Tris-HCl pH 8, 0.05M EDTA pH 8 and 1.25% SDS) were added to each tube. The mixture was then incubated at 65°C for 1 hour, and after cooling, the mixture was diluted with 6M vinegar. 187 μL of ammonium chloride (4°C) was added to each tube with thorough mixing. The samples were then centrifuged at 3000 rpm for 30 minutes. The supernatant from each tube was then stored at room temperature for 5 minutes. in new microfuge tubes each containing 220 μL of isopropanol for DNA precipitation for 1 min. The DNA was extracted by centrifuging the tube at 3000 rpm for 30 minutes. The collected DNA pellet was washed with 320 μL of 70% ethanol, dried, and then resuspended in 225 μL of water. The DNA was resuspended in PBS. Insoluble material was removed by centrifugation at 3000 rpm for 20 minutes. The cells were pelleted and 150 μL of each supernatant was transferred to a 96-well plate for long-term storage.
[0294] DNA is used to express transgenes or clones for efficient and quantitative digital PCR (ddPCR). To ensure that multiple copies of the insert are physically separated, restriction enzymes were used prior to the amplification reaction. Therefore, an aliquot of the DNA preparation was diluted with 10x EcoRI buffer, 5 μL of DNA EcoRI and Bam in a 20 μL volume using 4 units of each enzyme per L and sample. Digestion was carried out by incubation with HI at 37°C overnight.
[0295] The primers used in these PCR reactions were determined to be mutually exclusive between the reference and target gene primers. Ensure that no interactions are anticipated or that such interactions will not be a problem under the conditions of use. The reference gene used in the assay was , Brassica napus Hmg (high mobility group) present in one gene per Brassica napus genome gene (Weng et al., 2004). Because Brassica napus is an allotetraploid, In Brassica napus, four copies of the Hmg gene , i.e., there are two alleles of each of the two genes. The reference gene response is The following primer pairs and dual-labeled probes were used: sense primer, Can11 GCGAAGCACATCGAGTCA (SEQ ID NO: 50); antisense primer, C an12 GGTTGAGGTGGTAGCTGAGG (SEQ ID NO: 51); probe, H mg-P3 5'-Hex / TCTCTAC / zen / CCGTCTCACATGACG C / 3IABkFQ / -3' (SEQ ID NO: 52). The amplification product size was 73 bp.
[0296] The PPT selectable marker gene was used to screen all transgenic plants. In one target gene amplification reaction that detected the region, the sense primers were Can17, AT ACAAGCACGGTGGATGG (SEQ ID NO: 53); the antisense primer was Can18 TGGTCTAACAGGTCTAGGAGGA (SEQ ID NO: 54); Pro The probe is PPT-P3 5'- / FAM / TGGCAAAGA / zen / GATTTCG AGCTTCCTGC / 3IABkFQ / -3' (SEQ ID NO: 55). The gene amplification product was 82 bp. Sometimes, a second target gene assay is performed using T-DNase. This second assay was performed in parallel to detect the partial insertion of A. Can23 CAAGCACCGTAGTAAGAGAGCA (SEQ ID NO: 56), Sense primer, Can24 CAGACAGCCTGAGGTTAGCA (SEQ ID NO: No. 57); probe, D6des-P3 5'- / FAM / TCCCCACTT / ze n / CTTAGCGAAAGGAACGA / 3IABkFQ / -3' (SEQ ID NO: 58) The Δ6-desaturase gene region was detected using the Δ6-desaturase gene. The size was 89 bp. Reactions routinely used 2 μL of digested DNA preparation. Reaction composition per reaction: in a total volume of 25 μL, reference sense primer (10 pM), 1 μL; Antisense primer (10 pM), 1 μL; reference gene probe (10 pM), 0. 5 μL: target gene sense primer (10 pM), 1 μL: target gene antisense primer Primer (10 pM), 1 μL; target gene probe (10 pM), 0.5 μL; ddP CR reagent mixture, 12.5 μL; water 5.5 μL.
[0297] Then, a QX100 droplet press was used to divide each sample into 20,000 nanoliter-sized droplets. All samples were processed and transferred to a 96-well PCR plate. This was done in an 8-well cartridge until the plate was Heat seal with pierceable foil using a heat sealer machine. The samples were then treated under the following reaction conditions: 95°C for 10 minutes, 2.5°C / then 94°C for 30 seconds with a ramp of 2.5°C / second for 39 seconds Cycle: 61°C for 1 minute with ramping at 2.5°C / sec; 98°C for 10 minutes, then After the DNA amplification reaction in the droplets, the plate was subjected to a two-color detection system. Each droplet was individually placed into a QX100 droplet reader for analysis (FAM or Hex Droplet digital PCR data was plotted on a fluorescence intensity graph for each sample. 1-D plot of droplets, or plotting fluorescence (FAM) against fluorescence (Hex) for each droplet. The software displays the data for each fluorophore in each sample either as a 2-D plot or as a 3-D plot. The number of positive and negative droplets was measured for each solution (FAM or Hex). The software determines the input target DNA molecule concentration in units of copies / µL, so the positive The droplet fractions were fitted to a Poisson algorithm. Copy number variation was calculated using the formula: CNV = (A / B)*Nb (where A = target gene concentration, B = reference gene concentration, and Nb = 4, The number of copies of the reference gene in the genome was used to calculate the variance.
[0298] Assessment of pollen viability Fluorescein diacetate (FDA) was dissolved in acetone at 2 mg / ml to prepare the raw material. Sucrose solution (0.5M) was added until saturation was reached, indicated by the appearance of persistent cloudiness. The FDA dilutions were prepared immediately before use by adding 2 ml of FDA stock solution dropwise.
[0299] Propidium iodide (PI) was dissolved in sterile distilled water at 1 mg / ml to obtain a stock solution. Immediately before use, 100 μl of the stock solution was added to 10 ml of sterile distilled water to prepare a working solution. To check the ratio of powder to non-viable pollen, PI and FDA stock solutions were mixed in a 2:3 ratio.
[0300] Transgenic and oocytes were grown under standard conditions in a greenhouse at 22 ± 2°C with a 16-hour photoperiod per day. Wild-type rapeseed and mustard plants were grown. Mature flower buds ready to flower the next day. The pollen from bloomed flowers was stained with the FDA / PI mixture. and visualized using a Leica MZFLIII fluorescence microscope. GFP-2, 480 / A 510 nm long-pass emission filter with a 40 nm excitation filter (transmitting red and green light) Viable and non-viable pollen were detected using PI staining. Although they appeared red under the microscope, viable pollen appeared bright green when stained with PI and FDA. .
[0301] Example 2. Transgenic plant in Camelina sativa seeds Stable expression of the nicked DHA pathway
[0302] The binary vector pJP3416-GA7 (see Figure 2 and SEQ ID NO: 1) was Agrobacterium tumefaciens strain AGL1 and floral dilutions for transformation Transformed Agrobacterium used to treat Camelina sativa flowering plants using the tup method (Lu and Kang, 2008). Plant growth and maturation After that, T1 seeds of the treated plants were harvested and sown in soil. The resulting plants were transformed with pJP3416 -GA7 is transgenic for the bar selectable marker gene present in the T-DNA. To select for plants that express this gene, the plants were spray treated with the herbicide BASTA. The surviving herbicide-resistant T1 plants were self-pollinated and grown to maturity. 2 seeds were harvested. Five transgenic plants were obtained, and all three of these were It contained T-DNA.
[0303] Lipids were extracted from a pool of approximately 20 seeds from each of three plant species containing the complete T-DNA. Two of the pooled samples contained very low, barely detectable levels of DHA. The third pool contained approximately 4.7% DHA. Lipids were extracted from 10 individual T2 seeds from the same cultivar and the fatty acid composition was analyzed by GC. Individual seed fatty acid composition data for this transgenic line are also shown in Table 4. Total seed lipid protease activity The data collected from the files (Table 4) are shown in Table 5.
[0304] DHA was present in 6 of the 10 individual seeds. Four other seeds contained no DHA. does not contain T-DNA, based on hemizygous T-DNA insertion in the parent plant. The highest levels of DHA were extracted from a single seed. The lipids contained 9.0% DHA, while the total percentage of EPA, DPA, and DHA was 1. The rate was 1.4%. [Table 4] TIFF2023075083000013.tif24788 [Table 5]
[0305] Homozygous seeds from this line were obtained at the T4 generation. In event FD5-46-18-110, which had an average of 7.3% DHA, the DHA was produced in the subsequent generation (T5). In particular, the stability of DHA was further investigated. The prevalence was not stabilized until the T4 generation due to the presence of multiple transgenic loci. Despite this, the maximum DHA levels observed were found to be stable through the fifth generation. No obvious difference in germination efficiency or speed was observed between the T5 seed batch and the parent Camelina sativa. The seeds were then germinated on MS medium in vitro. The transgenic generations (T6, T7, etc.) did not show a decrease in seed DHA levels. The nicked plants are fully fertile and the pollen has approximately 100% viability, similar to that of wild-type plants. Analysis of the oil content of seeds containing different levels of DHA showed that Arabidopsis In contrast to the correlation observed in Ta.
[0306] In some further transgenic lines, DH of a single seed from an independent event The A content was over 12%. The transgenic:null ratio of these lines was approximately The ratio was found to be between 3:1 and 15:1. Representative lipids of the top DHA samples from each construct Analysis of the fatty acid profile did not detect any other new ω6 PUFAs, accounting for only 1.2-1.4%. In contrast, new ω3 PUFA (SDA), ω3 LC-PUFA ( ETA, EPA, DPA, DHA) with a DHA level of 9.6% of the total fatty acid content Δ6-desaturation was found to be 32% and EPA was found to be 0.5% of the total fatty acids. The Δ5-elongation efficiency was 93%, and the Δ6-elongation efficiency was 0.8%. The gating efficiency was 60%. Detected.
[0307] The observed segregation ratio (approximately 3:1 to approximately 15:1) was due to one or, at most, two translocations. The transgenic locus produces DHA levels similar to those found in Camelina sativa fish oil. This indicates that transgenic traits are essential for the stable transfer of the introduced gene. This has important implications not only for sex but also for ease of reproduction.
[0308] The homozygous seeds were distributed across several greenhouses to generate a total of over 600 individual plants. Various methods were used, including Soxhlet, acetone, and hexane extraction. Oil was extracted from the seeds.
[0309] To determine the positional distribution of ω3LC-PUFAs in TAG, transgenic camelina For Sativa seed oil, 13 C NMR regiospecific analysis was performed. Events with EPA and DHA were selected to maximize the response to these fatty acids. , the ratio of sn-1,3 to sn-2 is 0.75:0.25 for EPA, and D For HA, the ratio is 0.86:0.14, whereas the unbiased distribution would be 0.66:0.33. That is, 75% of EPA and 86% of DHA were located at the sn-1,3 positions of TAG. This means that although EPA has a lower priority than DHA, both fatty acids are essential for the development of turtles. The results showed that DHA is preferentially located at the sn-1,3 positions of the TAG of L. sativa. The finding that the 1st and 3rd positions were preferentially observed is in agreement with previous results reported in Arabidopsis seeds. The results were similar to those of (Petrie et al., 2012).
[0310] A few independent transgenic lines were obtained in the above transformation experiments, and further transgenic lines were then developed. L. sativa transformation was performed using the GA7-modB construct (Example 3). Many transformants were obtained and homozygous lines producing more than 20.1% DHA were identified.
[0311] Example 3. Modification pathway of T-DNA encoding DHA in plant seeds Improved DHA production level in rapeseed exceeding the level described in WO2013 / 185184 To improve the efficiency of the vectors, the binary vectors pJP3416-GA7-modA and pJP3416- GA7-modB, pJP3416-GA7-modC, pJP3416-GA7-mo dD, pJP3416-GA7-modE and pJP3416-GA7-modF, The constructs were constructed as described in O2013 / 185184 and tested in transgenic plants. These binary vectors are variants of the pJP3416-GA7 construct, specifically, Δ DHA synthesis in plant seeds by improving 6-desaturase and Δ6-elongase functions SDA has a relatively low activity compared to Δ5-elongase. In some seeds transformed with the GA7 construct, the Δ6-elongase efficiency was Among other modifications, two elongase gene loci are inserted into the T-DNA to allow for accumulation of It was observed that the
[0312] The two elongase encoding sequences in pJP3416-GA7 were inserted into the T-DNA These positions were switched to replace the Pyramimonas cordata Δ5-elongase cassette. To transfect the Pyramimonas cordata Δ6-enantiomers into the Sbf1 site of pJP3416-GA7, pJP3416-GA7-mo This construct was transformed into a microenvironmental vector under the conlinin Cnl2 promoter (pLuCnl2). The FP1 promoter driving the Pseudomonas pusilla Δ6-desaturase was replaced with p JP3416-GA7-modB was further modified to obtain Δ6-desaturated This modification was made in an attempt to increase enzyme expression and thereby enzyme efficiency. The truncated napin promoter results in higher expression of transgenes in Brassica napus There should be a possibility of obtaining
[0313] Eight transgenic pJP3416-GA7-modB Arabidopsis events and 15 transgenic pJP3416-GA7-modG Arabidopsis thaliana plants. A total of 7.7% of the pooled pJP3416-GA7-modB seeds were Between 0.2% DHA was observed in the pooled T2 pJP3416-GA7-modG strain. The highest DHA content was observed in the offspring of pJP3416-GA7- Some of the modB events were plated on selective media and the surviving seedlings were grown to the next generation. The offspring are analyzed for DHA content. Pooled T1 seeds are segregated for the transgene. The population represented a homozygous population containing any null segregants, so the offspring plants were homozygous. The researchers expected that this would increase DHA levels to 30% of the total fatty acid content in the seed oil. Other modified constructs were transformed into Arabidopsis thaliana. Although the transformants obtained were not able to obtain higher levels of DHA than the modB construct, There was no.
[0314] The pJP3416-GA7-modB construct was also used in cultivars Oscar and NX002, NX00 3. A series of breeding lines designated NX005, NX050, NX052 and NX054 Transformed Brassica napus plants were used to generate 77 independent Oscar transformations. Transgenic plants (T0) and their seed oils due to the effect of mutations in the FAD2 gene 189 for NX005, a line with a high oleic acid content in A total of 1558 transformed plants were obtained, including 1480 independent plants for the purpose of the present study. The T-DNA had low levels of LA and ALA as determined by digital PCR. Transgenic plants (Example 1) showing more than four copies of the Approximately 25% were culled by this criterion. Approximately 53% of the T0 transgenic plants were They have one or two copies of the T-DNA as determined by digital PCR, and % had approximately 3 copies, and 24% had 4 or more copies. After pollination, approximately 450 transgenic lines were harvested and allowed to flower to avoid outcrossing. The T1 seeds were then bagged onto the plants. Approximately 1-2% of the plant lines were either male or female sterile. As a result, no viable seeds were produced and the TO plants were discarded.
[0315] Seed pools (20 T1 seeds in each pool) were analyzed for DHA levels in the pooled seed oil. The strains with the highest levels were selected. Lines with a DHA content of at least 2% of the total fatty acid content in the offspring were selected. % of the transgenic lines were selected in this way; the other 85% were culled. Some of the lines are CT132-5 (variety Oscar), CT133-15, -24, -63, They were named -77, -103, -129 and -130 (NX005). The lines are CT136-4, -8, -12, -17, -19, -25, -27, -49 and -51. 20 seeds of selected lines including CT132.5 and 11 seeds of CT133.15 The seeds were soaked and after 2 days, oil was extracted from half the cotyledons from each individual seed. The other half of the cotyledons were kept and cultured on medium to maintain the specific progeny line. The acid composition was determined; the data is shown in Table 6 for CT132.5. 20 seed sacs analyzed The DHA levels in these 10 range from 7 to 20% of the total fatty acid content as determined by GC analysis. The other seeds contained less than 7% DHA and were derived from pJP3416-GA7-modB. It is possible that the plants contained partial (incomplete) copies of the T-DNA of the transgenic plants. The lines appeared to contain multiple transgene insertions that were not genetically linked. Seeds from the transgenic line CT133.15 contain DHA levels ranging from 0 to 5%. Seeds without DHA appeared to be null segregants. These data Therefore, the modB construct was found to be sufficient for DHA production in canola seeds. Confirmed.
[0316] 20 or 4 T1 plants obtained from each of the selected transgenic lines after self-pollination 0 individual seeds (T2 seeds) were individually tested for fatty acid composition. Seeds containing DHA at levels similar to those of CT136-27- were identified (Table 7). 18-2 and CT136-27-18-19 were 21.2% and 22.7%, respectively. The total omega-3 fatty acid content in these seeds was 100% of the total fatty acid content. The ω6 content was approximately 60% at the time of analysis, and less than 10% at the time of analysis. Alternatively, a set of 40 T2 seeds was tested for fatty acid composition. DH up to 34.3% Seeds containing A were identified, for example, in seed CT136-27-47-25 (Table 9). The fatty acid composition of the seed oil obtained from 136-27-47-25 is shown in Table 9. The composition is 34.3% DHA along with approximately 1.5% DPA, 0.6% EPA and 0.5% ETA. The SDA level was approximately 7.5%, ALA approximately 21.9%, and LA approximately 6. The new ω6 PUFA showed GLA 1.1%, but ω6-C20 and -C22 No LC-PUFAs were detected. Total saturated fatty acids: 9.6%; monounsaturated fatty acids: 12% 0.5%; total PUFA, 75.2%; total ω6-PUFA (including LA), 7.2%; total ω3 -PUFA, 66.9%; total ω6:ω3 fatty acid ratio, 9.3:1; neoω6:neoω3 fatty acids , 37:1. The efficiency of each enzymatic step from oleic acid to DHA was as follows: Δ12-desaminated DHA; Δ15 / ω3-desaturase, 90%; Δ15 / ω3-desaturase, 89%; Δ6-desaturase, 67%; Δ6-elongase, 83%; Δ5-desaturase, 99%; Δ5-elongase Δ4-desaturase, 98%; Δ4-desaturase, 96%. Overall efficiency of oleic acid conversion to DHA. The percentage of fatty acids in the seed oils was approximately 50%. DHA-producing seeds contain between 20.1% and 30% DHA or 20.1% of the total fatty acid content. The seeds were identified as containing between 30% and 35% DHA and were clearly selected. Ta.
[0317] The oil content in some seeds ranged from about 44% in wild-type seeds to 10% in some DHA-producing seeds. The DHA content in the seeds was reduced to about 31-39%, but this was similar to the wild-type levels in other DHA-producing seeds. It was.
[0318] Crossing various transgenic plant lines that produce DHA at levels of at least 10% in T2 seeds to produce F2 progeny homozygous for multiple T-DNA insertions. The F1 progeny were then self-pollinated. Seed oil from homozygous seeds was analyzed, and the contents of the seed oil were Up to 30% or 35% of the total fatty acid content is DHA.
[0319] In oils obtained from CT136-27-18-2 and CT136-27-18-19 The positional distribution of DHA on the glycerol backbone of the TAG molecule was 13 CN DHA preferentially binds at the sn-1,3 position. More than 70%, in fact more than 90%, of the DHA was at the sn-1,3 position. Ta.
[0320] In some further transgenic lines, DH of a single seed from an independent event The transgenic:null ratio of these lines was 1.5%. The ratio of the two transgenic loci was approximately 3:1. The ratio of each construct with the highest level of DHA was found to be 15:1, corresponding to the The analysis of the representative fatty acid profile of the samples from these researchers showed that they did not contain any new ω6 PUFAs and had a fatty acid content of 1.2 to 1. Only 0.4% of GLA was detected. In contrast, the new ω3 PUFA (SDA) and ω3 LC- PUFA (ETA, EPA, DPA, DHA) in GA7-transformed seeds. 25.8% for the modF construct and 21 for the modG construct compared to 5%. The DHA levels in the oils of these seeds were 9.6% and 9.9%, respectively. , 12.4% and 11.5%. Δ6-desaturation was observed in the modF- and modG-forms. The GA7-transformed seeds were lower than the GA7-transformed seeds (32% vs. 47% and 43%), which , which resulted in a decrease in ALA in modF and modG compared to GA7. Another notable difference was the accumulation of EPA in modF seeds (compared to the other two transgenic plants). 3.3% vs. 0.8% in the nick seeds, which is higher than the GA7 and modG seeds (93% and 9 The lower Δ5-elongation observed in modF (80%) seeds compared to modF (4%) The slightly more active Δ6-desaturation actually increased the amount of SDA. However, there was a slight increase in Δ6-elongation in these seeds (66% vs. 60% and 6 DHA was detected in the polar seed lipid fraction of the GA7 line.
[0321] 7 of the rapeseed breeding line NX54 transformed with the T-DNA of the modB construct The fatty acid composition of lipids in the T1 seeds of 0 independent transgenic plants was analyzed. One of the transgenic plants contains DPA but no DHA in its seed oil. The T1 seeds of this line (CT-137-2) were observed to produce seeds. The present inventors have found that the corn starch produced approximately 4% DPA with no detectable DHA in the seeds. This indicates that spontaneous mutations have resulted in the development of Δ4-desaturases in that particular inserted T-DNA. We investigated whether the inactivation of the enzyme gene was the cause of the disease by PCR analysis and DNA sequence analysis. The deletion was observed at nucleotides 12988-15 of the T-DNA of GA7-modB. A deletion of 317 was revealed (SEQ ID NO: 2). The deleted nucleotide is a Δ4-desaturase. The Linus Cnl2 promoter portion driving expression of the enzyme coding region and Δ 4-desaturase coding region itself, thereby defining the T-DNA containing the deletion. This explains why seeds transformed with β-actin did not produce DHA.
[0322] Approximately 50 T1 seeds from this transgenic line were germinated, and one seed from each was harvested. The ripe cotyledons were analyzed for fatty acid composition in the remaining oil. Selected seedlings showing DPA were grown to maturity and T2 seeds were harvested. The acid composition is shown in Table 8, and more than 7% DPA was observed in these lines. It was produced from the Brassica napus DPA line CT-137-2 and contains fatty acid protease. A maximum of 13% DPA was detected in the mature seed samples collected. It was observed that
[0323] Oil from seeds containing approximately 10% DPA was treated with mild alkali to dehydrate the fatty acids. I understood.
[0324] Another transgenic line designated B0003-514 showed approximately It showed 10-16% DPA, 15.8% DPA, 0.2-0.9% DHA, and Seeds containing 0.1-2.5% EPA were selected. The T2 seed group was characterized by high DPA:medium DPA. The PA:non-DPA ratio was 1:2:1. In the feline strain, the existence of a single locus for DPA production is suggested.
[0325] Oil was extracted from LC-PUFA-producing seed samples using a screw press. Seed meal was prepared from the above.
[0326] Structure design While the focus of this experiment was to demonstrate the production of DHA and DPA within oilseed crop species, These results were also interesting from a construct design perspective. First, the Δ6- and The switch in the position of the Δ5-elongase coding region resulted in lower Δ5-elongation. This resulted in the intended profile change, which included more EPA accumulated due to the Δ6- A concomitant increase in elongation was observed, which resulted in lower SDA levels. This is due to the fact that the truncated napin promoter is driven by the more active amaryllis 2 promoter. Substitution of the motor (FP1) as well as extraneous expression in Micromonas pusilla Δ6-desaturase Δ6-desaturation in modF-transformed seeds caused by the addition of a lyase expression cassette The somewhat smaller increase in Δ6-desaturation observed with the modG construct was due to , resulting from the utilization of a highly expressed Δ5-elongase cassette in GA7. The switch in the position of the Δ5-elongase and Δ6-elongase coding regions results in greater Δ6-desaturation. In this case, replacement of the FP1 promoter with the Cnl2 promoter resulted in did not decrease Δ5-elongase activity.
[0327] These data indicate that the modB, modF, and modG constructs are useful in Arabidopsis and Like rapeseed, camelina seeds showed good results for DHA production.
[0328] The inventors have generally found that the efficiency of rate-limiting enzyme activities in the DHA pathway is significantly reduced in the single-copy T-DNA form. The pathway may be greater in multicopy T-DNA transformants compared to transgenic transformants. It is thought that this can be increased by inserting multiple genes into the T-DNA that encode enzymes that can be restricted within the Evidence for the possible importance of multicopy transformants was obtained by transforming with the GA7 construct. The highest yielding DHA events observed in transformed Arabidopsis seeds were those in the host genome. The multiple genes can be the same or, preferably, are different variants encoding the same polypeptide or have overlapping expression patterns. For example, even if the same protein is produced, Therefore, increased expression should be achievable by expression of multiple Δ6-desaturase coding regions. In pJP3416-GA7-modF and pJP3416-GA7-modC, For example, there are two variants of Micromonas pusilla Δ6-desaturase, which have different The coding sequences were expressed by different codon usage and therefore different nucleotide sequence, reducing the potential silencing or co-suppression effect but resulted in the production of the same protein. [Table 6] [Table 7] [Table 8] [Table 9]
[0329] Example 4. Analysis of TAGs in transgenic Arabidopsis seeds producing DHA The positional distribution of DHA on TAG in transgenic Arabidopsis seeds was measured by NMR. Total lipids were analyzed by hexane before transferring the ground seeds to a glass tube containing 10 mL of hexane. Extraction was performed from approximately 200 mg of seeds by first crushing the seeds under a microscope. The hexane solution was heated to approximately 55°C in a bath, then vortexed and centrifuged. The extracts were combined and rotary evaporated. The lipid extract was concentrated in a porator, and TAG in the lipid extract was extracted with 20 mL of 7% diethyl ether in hexane. The lipids were separated from the polar lipids and purified by passage through a short silica column. The acyl group position distribution on purified TAG was quantitatively determined as previously described (Petrie et al., 2014). 010a and b).
[0330] Analysis showed that the majority of DHA in the total seed oil was located at the sn-1 / 3 position of TAG, This indicates that the sn-2 position was hardly observed. :4 Δ5、8、11、14 ) 50% of the sn-2 of transgenic canola oil While the ARA-producing seeds were ranked high, only 33% were found to be within the range expected for random distribution. This was in contrast to TAG from (Petrie et al., 2012).
[0331] The total lipids of transgenic Arabidopsis seeds were analyzed using the major DHA-containing triacylglycerols. The compounds were also analyzed by triple quadrupole LC-MS to measure the cerol (TAG) species. The most abundant DHA-containing TAG species was DHA-18:3-18:3 (TAG58: 12; nomenclature that does not express positional distribution), and the second most abundant is DHA-18: 3-18:2 (TAg58:11). 66:18) were observed in total seed oil at low, but detectable levels. The main DHA-containing TAG species are DHA-34:3 (TAG 56:9) and DHA-36:3 (TAG58:9), DHA-36:4(TAG58:10), DHA-36:7(TA The two main D The HA-containing TAG species were further confirmed by Q-TOF MS / MS.

Assay of sterol content and composition of oils Phytosterols from 12 plant oils purchased from commercial sources in Australia. is the O-trimethylsilyl ether (OTMSi-ether) derivative described in Example 1 The sterols were characterized by GC and GC-MS. Identification was achieved by toll analysis and comparison of literature and experimental standard mass spectral data. was quantified by using 5β(H)-cholan-24-ol internal standard. The phytosterol base structure and chemical structure of the hydroxybenzoates are shown in Figure 3 and Table 10.
[0333] The plant oils analyzed were: sesame (Sesamum indicum), olive (Oli ea europaea), sunflower (Helianthus annuus), castor bean (R icinus communis), Brassica napus ), safflower (Carthamus tinctorius), peanut (Arach is hypogaea), flax (Linum usitatissimum) and daikon The relative abundances across all oil samples were In the reduction of phytosterols, the main phytosterols were: β-sitosterol (28% of the total sterol content); ~55% range), Δ5-avenasterol (isofucosterol) (3-24%), Δ5-stigmasterol (2-33%), Δ5-stigmasterol (0.7-18%), Δ7- Stigmasterol (1-18%) and Δ7-avenasterol (0.1-5%) Several other minor sterols were identified, these being: cholesterol, brassica ternate The four C29 C30:2 and two C30:2 sterols were also detected, but the identification of these minor components has not been completed. Further investigation is needed to determine whether this is the case. In addition, some of the other identified sterols Although present in some of the oils, due to its very low abundance, the mass spectra The intensity was not sufficient to identify the structure. [Table 10]
[0334] The sterol content expressed as mg / g of oil in the reduced amounts was: canola oil (6. 8mg / g), sesame oil (5.8mg / g), flaxseed oil (4.8-5.2mg / g) , sunflower oil (3.7-4.1mg / g), peanut oil (3.2mg / g), Safflower oil (3.0 mg / g), soybean oil (3.0 mg / g), olive oil (2.4mg / g), castor oil (1.9mg / g).
