Abstract

A plant-based ingredient obtained or available from a Pisum sativum pea, wherein a representative sample of seeds of this plant has been deposited under NCIMB No. 44382, wherein the plant-based ingredient has an improved taste profile compared to a plant-based ingredient from a pea of ​​a Pisum sativum reference plant, wherein the improved taste profile is due to at least one signature mutation in at least one gene, preferably a signature mutation as shown in Table 1, including the gene Psat03G0335100, which is involved in the saponin biosynthesis pathway.

Description

AREA OF INVENTION

[0001] This disclosure relates to plant-based ingredients, in particular protein ingredients, suitable for use in foods, including vegetarian or vegan meat or dairy analogues. The plant-based ingredients are obtained from a novel line of peas, which imparts an improved flavor profile to their ingredients. BACKGROUND OF THE INVENTION

[0002] The challenges arising from continuous population growth, malnutrition and obesity, as well as environmental changes, have led to strong market interest in plant-based ingredients in recent years. Food manufacturers face the challenge of providing plant-based food alternatives on a large scale that meet consumer expectations in terms of taste, texture, and other organoleptic properties.

[0003] To meet these requirements, food manufacturers have considered various plant-based protein sources, including but not limited to soybeans, peas, chickpeas and split peas, lupins, hemp, potatoes, wheat, cranberries, beans such as marine, pinto, adzuki, fava, lima, black, red kidney and mung beans, pumpkin seeds and seeds of other squashes, and grains such as rice, sorghum and millet.

[0004] One of the main limitations of using plant-based ingredients, such as plant-based proteins, in food products is the perception of off-flavors. These off-flavors can be mitigated to some extent by natural flavorings and flavor-masking agents. However, the presence of certain aroma- and flavor-active compounds in plant-based isolates or concentrates makes the product development process cumbersome, costly, and time-consuming, and may also be perceived as undesirable by consumers.

[0005] Peas, as a plant-based ingredient source, particularly as a protein source, have attracted considerable interest from the food industry and consumers in recent years. The endogenous nitrogen source in peas reduces their soil requirements and is responsible for their high protein content, making peas an excellent source of plant-based protein. Furthermore, as a high-quality protein source, peas have a much lower carbon footprint (CO2 in g / 100 g of protein produced) compared to meat-based protein sources or eggs (from chickens) (Sustainable Protein Sources. 1st edition, 2016, Editors: Sudarshan Nadathur, Janitha PD Wanasundara, Laurie Scanlin, eBook ISBN: 9780128027769).

[0006] However, it has been shown that cultivated varieties of Pisum sativum L. differ considerably in their chemical composition, including their protein, fat, and starch content. Both volatile and non-volatile compounds contribute to the sensory profile of peas and pea-based ingredients, based on their actual and relative concentrations.

[0007] These differences in chemical composition necessitate specific manufacturing methods and parameters, which may require individual batch-to-batch adjustments or continuous process modifications, thus limiting the possibilities for large-scale production or use of pea-based ingredients. Such variations also lead to fluctuations in the properties of the ingredients and the final product, including organoleptic properties such as taste and aroma, making the use of pea-based ingredients in commercial food production challenging.

[0008] There is therefore a constant need for pea components that exhibit fewer off-flavors, improved taste and organoleptic properties. Furthermore, there is a great need to define and create suitable germplasm and pea lines that can be cultivated sustainably and contain plant protein components with high nutritional value, particularly in terms of their nutritional content.

[0011] The term "aroma", as used herein, refers to a property that can be detected by taste and / or smell.

[0012] The term "non-volatile flavor components," as used herein, refers to molecules that impart a flavor to a product but are not volatile in the sense that they cannot be removed by methods such as evaporation. The term applies to both liquids and solids.

[0013] The term "off-flavor" or "off-flavors," as used herein, refers to an undesirable aroma and relates to the complex interactions of various taste descriptors such as bitter, sour, earthy, beany, salty, sweet, green, nutty, umami, and the like. Furthermore, other organoleptic parameters such as dry, dull, powdery, moist, and the like also play a role in taste perception and are collectively referred to here as "off-flavors."

[0014] The term "plant-based ingredient," as used herein, refers to any ingredient obtained from plants or plant parts in processed form, including protein ingredients, soluble carbohydrate ingredients such as starch, insoluble carbohydrate ingredients such as fiber, lipid ingredients, ash ingredients, and the like. A plant-based ingredient may contain any combination of proteins, carbohydrates, fats, or ash, etc., in any proportion. The term "plant-based ingredient" may be used interchangeably with the term "plant-based food ingredient" herein.The terms “protein ingredient”, “starch ingredient”, “carbohydrate ingredient”, “lipid ingredient” or “ash ingredient”, as used herein, include any form of such ingredient suitable for use on its own or in combination with other components of a formulation, such as the formulation for a plant-based composition or an (alternative) food product.

[0015] The plant-based ingredient can be in the form of an isolate, concentrate, flour, textured product, and the like.

[0016] “Protein textureate” or “textured protein,” as used herein, refers to an ingredient that possesses structural integrity and an identifiable structure such that individual units, occurring as fibers, slivers, chunks, pieces, granules, discs, and the like, can withstand hydration and cooking or other processes of preparing food for consumption. In general, textured proteins can be used to modify or enhance texture and to bind water. Edible protein sources from which textured proteins are produced include, but are not limited to, pulses (e.g., pulse protein), peas, soybeans, corn, wheat, chickpeas, potatoes, rice, sunflowers, and the like.Textured proteins include, but are not limited to, textured pea protein, textured soy flour, textured soy concentrate, textured wheat protein, textured potato protein, or combinations thereof. Methods for texturing proteins are known and described in the scientific community and may include, for example, high-temperature and pressure extrusion, spinning, freeze texturing, chemical or enzymatic texturing, and the like. “Protein flour”, as used herein, refers to an ingredient containing ground peas.

[0017] An “alternative edible product ingredient,” as used herein, refers to a plant-based ingredient, including a protein ingredient, that is suitable as part of an “edible product” or “edible composition.” Furthermore, at least a part or fraction of the “alternative edible product ingredient” is suitable as a substitute for a well-known and commonly manufactured product ingredient, typically being suitable as an alternative to, for example, animal-derived or animal-produced ingredients or foods, including meat, eggs, or dairy products.

[0018] An “alternative food,” as used herein, may be in liquid, semi-liquid, or solid form. An “alternative food,” as used herein, refers to a product for human or animal consumption that is normally made with ingredients from animal sources, but in which the animal ingredient has been partially or completely replaced by a plant-based substitute ingredient. Non-restrictive examples of alternative food products include alternative beverages such as a milk substitute or a drinkable yogurt substitute, or alternative food products such as a substitute for eggs, beef, dairy products, poultry, or seafood. Alternative foods also include pet or animal feed products in which some or all of the animal-derived ingredients have been replaced by plant-based ingredients.The exchange or replacement of the animal-derived component may, in some embodiments, amount to more than 70%, 80%, 90%, or 95%. In other embodiments, the exchange or replacement of ingredients of animal origin may amount to 70% or less, e.g., 60%, 50%, 40%, etc. Alternative foods may also include dairy-free beverages such as sports drinks or smoothies. Alternative foods may also refer to alternative food products, such as plant-based powders used as dietary or nutritional supplements.

[0019] An “alternative food,” “alternative diet,” or “alternative (food / cosmetic) product / composition,” as used herein, refers to a food, including liquid foods such as beverages, that is typically plant- or microorganism-based and represents an alternative to foods of animal origin, including meat or dairy products. Alternative foods may be of particular interest as alternative protein sources, but the term “alternative food” refers to any type of nutrient building block, including proteins, carbohydrates, lipids, vitamins, minerals, fiber, and the like, that is suitable for food production and that is well-accepted or even healthy as food and feed for humans or farm and domestic animals.An alternative food product or an alternative foodstuff thus represents an "alternative edible product" or an ingredient thereof. The ingredients of the present invention are suitable for use in an alternative foodstuff, an alternative feedstuff, or an alternative cosmetic.

[0020] An alternative product or composition, as used herein, and any pea protein ingredient suitable for the manufacture of the present invention, is specifically processed (industrially and / or mechanically and / or chemically and / or enzymatically), and a pea protein ingredient of this invention is typically processed, isolated, concentrated, and / or otherwise treated to be incorporated into an alternative product or composition. Furthermore, a pea protein ingredient of this invention typically represents an intermediate ingredient that has been or can be isolated from a plant that constitutes a part or fraction of a final product or composition, or a mixture or hybrid product.In an alternative product or composition, the pea protein ingredient of this invention, as an alternative part or fraction of the alternative product or composition, thus replaces a part or fraction that would be present in a generally known and commonly produced product or composition, preferably replacing a part or fraction of animal or non-plant origin in the corresponding generally known and commonly produced product.

[0021] In particular, the term ‘food’ as used herein refers to food intended for human consumption, while ‘feed’ as used herein refers to animal feed.

[0022] “Milk substitute” or “milk substitute composition” or “milk alternative” or “milk alternative product”, as used herein, refers to compositions that mimic the general appearance, nutritional content, and / or taste of dairy products made using animal milk products without containing animal milk or being substantially free of animal products, and includes hybrid products made with laboratory-grown, fermented, and animal-derived components, such as protein components. The milk substitute may be completely free of animal milk or animal milk protein, or virtually free of animal milk protein, such as 90% or 95% free of animal milk protein. The milk substitute may be a dairy-free cheese, a dairy-free yogurt, a dairy-free ice cream, and the like.

[0023] “Meat substitute” or “meat substitute composition” or “meat alternative”, as used herein, refers to compositions that mimic the general, organoleptic, and / or nutritional properties of edible products manufactured using any type of meat or meat analogue, including meat, fish, poultry, laboratory-grown, and fermented meat products. This definition also includes hybrid products made from laboratory-grown, fermented, and animal components, such as protein components. A similar definition is used herein for “egg substitute”, “egg substitute composition”, and “egg alternative”.Whenever the terms “composition” or “pea protein composition” are used herein, they refer to a composition of any of the protein constituents, flours, concentrates, or isolates disclosed herein, used in extracted form together with other ingredients of different origins to provide said composition. An alternative food or cosmetic product is thus also a composition in this sense. In this context, a “mixture” or “pea protein mixture” is a specific type of composition in which pea protein fractions from different peas, or even from different plants or other sources, are blended together to provide a base protein mixture (and optionally other additives or ingredients of different types and / or origins) containing pea protein of the present invention.

[0024] A “consumer product,” as used herein, refers to goods that are typically consumed or used up in the normal course of business, such as food and beverages, office supplies, cleaning and sanitary products, and medical supplies. There are generally two main types of consumables: durable consumables, which can be used over a long period, and non-durable consumables, which can be used up relatively quickly. Examples of consumables include perishable food and beverages, paper products, ink cartridges, cleaning chemicals, gloves, and syringes.The consumer goods specifically addressed here are non-permanent products that are non-toxic when swallowed or applied to the human or animal body, according to their intended use, and are typically manufactured from at least one organic raw material (and optionally others), including foods, beverages, gels, ointments, toothpaste, and the like. "Consumable products / compositions" within the meaning of the present invention are alternative products or compositions comprising at least one alternative plant-based ingredient, preferably a protein ingredient, as defined in the present invention.

[0025] A “gene,” as used herein, refers to the coding region of a gene, the non-coding region, and upstream and / or downstream regulatory sequences, including enhancers, silencers, promoter elements (e.g., proximal, distal, and nuclear promoters), and 5' and / or 3' UTRs. Therefore, the modification of a gene may also include the modification of a non-coding and / or regulatory sequence thereof.

[0026] A “hybrid composition / product” or a “hybrid alternative (consumer, including food / cosmetic, etc.) composition / product” as used herein refers to a product that at least partially comprises an “alternative food” or “alternative diet” or an “alternative (food) product” that includes a protein substance of plant origin according to the present invention, but which may include further components.

[0027] A "knockdown" of a gene refers to an experimental technique in which the expression of the gene (i.e., the transcription of DNA into RNA and thus the amount of active RNA transcripts) is reduced. Reduced expression can be achieved, for example, by gene silencing, in which the transcription rate is reduced or stopped, thereby decreasing the amount of available functional RNA.

[0028] A "knockout," on the other hand, leads to a complete loss of expression (transcription / translation). This means the gene is not fully transcribed or is transcribed incorrectly, resulting in either complete loss of expression or (at the protein level) expression to such an extent that almost no functional protein is expressed, or only very slightly at or above the detection limit. This can be achieved, for example, by exchanging or interrupting the sequence of the target gene. For instance, an early or premature additional stop codon, preferably near the start codon, can lead to premature transcription termination, resulting in the complete loss of the functionally translated protein. Alternatively, a knockout can be achieved by a mutation that alters the naturally occurring splice donor or splice acceptor site of a eukaryotic gene, encompassing exons and introns.The splice donor site typically comprises a nearly invariant GU sequence at the 5' end of the intron within a larger, less highly conserved region. The splice acceptor site at the 3' end of the intron terminates the intron with a nearly invariant AG sequence. If these conserved sequences are mutated, RNA splicing is altered, which can also lead to a knockout, measured at the transcriptional (RNA) or translational (protein) level. Consequently, a single targeted nucleotide exchange, deletion, or insertion can result in a functional knockout in the sense that the sequence encoded by a gene is no longer transcribed or translated. A knockout can also occur through a deletion of a gene or a substantial portion thereof at the genomic level, possibly accompanied by substitution with another sequence.

[0029] A “mutation” or “genome modification” within the scope of the present invention refers to any modification of a coherent nucleic acid sequence by modifying a nucleic acid sequence at a specific nucleotide sequence position, resulting in at least one difference in the (nucleic acid) sequence that distinguishes it from the original sequence. A modification can be achieved, in particular, by insertion or addition of one or more nucleotides, or by substitution or deletion of one or more nucleotides of the original sequence, or by any combination thereof.

[0030] A “nucleic acid construct”, “construct”, or “expression construct” refers to a nucleic acid molecule that encodes or comprises one or more genetic elements which, upon introduction into a target cell, can be transcribed and / or translated into a functional form, e.g., RNA(s), polypeptide(s), or protein(s). A nucleic acid construct may also include regulatory sequences such as promoter and terminator sequences that facilitate the expression of the genetic element(s), as well as spacers and introns. The genetic elements of the present invention may also be encoded on a set of constructs, the constructs of which can be introduced into a cell simultaneously or sequentially.

[0031] The term “RNAi,” or “RNA silencing,” or “gene silencing,” as used interchangeably herein, refers to the process known as RNA interference, a mechanism for downregulating (or knocking down) genes, which has now been identified in all eukaryotes. The mechanism was originally recognized and described in plants, where it was termed “post-transcriptional gene silencing,” or “PTGS.” In RNAi, small RNAs serve to direct specific effector proteins to a target nucleotide sequence through complementary base pairing, resulting in the degradation of the target. A “gene silencing construct” or “RNAi agent” typically includes so-called “sense” and “antisense” sequences. Sense and antisense sequences are complementary sequences that exist in reverse orientation within a nucleic acid sequence.If a nucleic acid construct comprises a sense and a corresponding antisense sequence, the two complementary sequences form an RNA double strand during transcription, resulting in an "RNA hairpin". In an RNA hairpin, sense sequences and their corresponding antisense sequences together form a double strand and are separated by an "interposed intron loop sequence" that forms the loop of the hairpin structure.

[0032] The terms Pisum sativum (L.) plant and pea plant, or simply pea, are used interchangeably here, whereby the term pea is used in connection with the plant as a whole, but also to refer to parts of it, especially seeds / fruits in pea pods.

[0033] A “(pea) plant constituent,” as used herein, refers to the total amount of protein that can be extracted from a (pea) plant fruit or seed (dry or fresh). A “(pea) protein constituent,” in turn, refers to the total amount of protein in the (pea) plant.

[0034] The term "protein concentrate" refers to a protein ingredient with a concentration of approximately 30% to 60%. A "protein isolate" is an even more concentrated protein ingredient with a concentration of approximately 60% to approximately 100%. "Protein flour" represents the protein that can be obtained directly after dehulling and milling. Because this protein flour is not yet heavily processed, it reflects the original protein content quite directly. Therefore, "protein flour" was also used by the inventors to define standard ratios when comparing different materials. "Protein textured" or "textured vegetable protein" refers to a flour product that has usually been further defatted and is particularly well-suited and used as a meat analogue or meat extender. It cooks quickly and has a protein content comparable to some meats.The terms "protein flakes" or "protein powder" describe the form of the protein. A "protein powder" is typically composed of fine, dry particles produced by grinding, crushing, or dissolving a solid substance.

[0035] The term “vector” refers to an element used to introduce a nucleic acid construct or set of nucleic acid constructs into a cellular system. The vector may be a plasmid or plasmid vector, a cosmid, yeast artificial chromosomes (YAC), a bacterial artificial chromosome (BAC) or P1 artificial chromosomes (PAC), a phagemid, a bacterial phage-based vector, a modified viral vector, an Agrobacterium shuttle vector, an isolated single-stranded or double-stranded nucleic acid sequence comprising DNA and RNA sequences in linear or circular form, or a mixture thereof, for introduction or transformation into a plant, plant cell, tissue, organ, or material as disclosed herein.

[0036] The terms "plant," "plant cell," or "plant part," as used herein, refer to a plant organism, a plant organ, differentiated and undifferentiated plant tissues, plant cells, seeds, and their derivatives and progeny. Plant cells include, without limitation, cells from seeds, from mature and immature cells or organs, including embryos, meristematic tissue, seedlings, callus tissue at various stages of differentiation, leaves, flowers, roots, shoots, male or female gametophytes, sporophytes, pollen, pollen tubes and microspores, as well as protoplasts, etc.

[0037] "Mutagenesis" refers to a technique in which modifications or mutations are introduced into a nucleic acid sequence in a random or non-site-specific manner. Mutations can be induced, for example, by certain chemicals such as EMS (ethyl methanesulfonate) or ENU (N-ethyl-N-nitrosourea), or physically, such as by irradiation with UV or gamma rays. "Site-specific modifications," on the other hand, rely on the action of site-specific effectors such as nucleases, nickases, recombinases, transposases, base editors, prime editors, and the like. These tools recognize a specific target sequence and allow a modification to be made at a particular location within that sequence.

[0038] A “protein composition,” as used herein, refers to a protein isolate that can be obtained directly from a fruit, a seed, in particular from a specific pea of ​​the genus Pisum, or from a flour, protein fraction, or purified or partially purified protein fraction. Depending on the method of its preparation, the protein composition may contain denatured and / or partially fragmented proteins, as the proteins may have been denatured and / or fragmented during thermal, chemical, and / or mechanical processing / purification. A protein composition may consist substantially of one protein or a fragment thereof, in particular convicilin, or it may be a mixture of protein compositions containing other proteins, in particular globulins and other pea proteins.

[0039] TILLING (Targeting Induced Local Lesions in Genomes) is a method that allows the identification of mutations in a specific gene after (non-specific) mutagenesis. The mutagenesis can be performed, for example, with a chemical mutagen such as EMS. Subsequently, a sensitive DNA screening method is used to identify mutations at individual bases. Methods for performing TILLING are known to those skilled in the art.

[0040] A “functional homolog,” as used herein, refers to a molecule that has essentially the same function as a reference molecule. A “structural homolog” refers to a homolog that has a substantial degree of sequence identity with a reference molecule or a part thereof from which it is derived.

[0041] The term "nucleotide sequence" in connection with the present invention includes genomic DNA, cDNA, synthetic DNA and RNA. Preferably, it refers to DNA, in particular genomic DNA.

[0042] Amino acids are referred to here by their name, three-letter abbreviation, or one-letter abbreviation. The term "protein," as used herein, includes proteins, polypeptides, and peptides. The term "amino acid sequence," as used herein, is synonymous with "polypeptide" and / or "protein." In some cases, "amino acid sequence" is synonymous with "peptide." In some cases, "amino acid sequence" is synonymous with "enzyme."

[0043] A "conservative amino acid substitution" is a substitution in which the amino acid residue is replaced by an amino acid residue with a similar side chain. In the scientific community, families of amino acid residues with similar side chains have been defined. These families include amino acids with basic side chains (e.g., lysine, arginine, histidine), acidic side chains (e.g., aspartic acid, glutamic acid), uncharged polar side chains (e.g., glycine, asparagine, glutamine, serine, threonine, tyrosine, cysteine), nonpolar side chains (e.g., alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, tryptophan), beta-branched side chains (e.g., threonine, valine, isoleucine), and aromatic side chains (e.g., tyrosine, phenylalanine, tryptophan, histidine). Therefore, a predicted non-essential amino acid residue in a protein according to the invention is preferably replaced by another amino acid residue from the same side chain family.

[0044] Conservative amino acid substitutions can occur along the entire length of the polypeptide sequence of a functional protein, such as an enzyme. In one embodiment, such mutations do not affect the functional domains of an enzyme. In another embodiment, the conservative mutations do not affect the catalytic sites of an enzyme.

[0045] In the present disclosure and the claims, the conventional one- and three-letter codes for amino acid residues can be used. The three-letter code for amino acids is defined in accordance with the IUPAC Joint Commission on Biochemical Nomenclature (JCBN). Due to the redundancy of the genetic code, a polypeptide can also be encoded by more than one nucleotide sequence.

[0046] A plant line that is “homologous” or a “homologous line” to KWS063, as used herein, refers to a line created by modifying or introducing at least one Psat locus, as described in Table 1, based on the present disclosure, to selectively modify a gene in the saponin pathway in accordance with the present disclosure, based on the knowledge and teachings provided for KWS063. Furthermore, orthologous genes to those identified herein may also be derived and used to provide plants with an optimized saponin biosynthesis pathway, e.g., in other plants of the Fabaceae family, formerly Leguminosae (here used interchangeably).

[0047] Where this disclosure refers to the percentage of identity between nucleic acid or amino acid sequences, or to the identity of a homolog, ortholog, or parolon of a particular gene locus with another, these values ​​define the values ​​obtained using the EMBOSS Water Pairwise Sequence Alignments (nucleotide) program (www.ebi.ac.uk / Tools / psa / emboss_water / ) for nucleic acids or the EM-BOSS Water Pairwise Sequence Alignments (protein) program (www.ebi.ac.uk / Tools / psa / emboss_water / ) for amino acid sequences. Alignments or sequence comparisons, as used herein, refer to an alignment over the entire length of two sequences being compared. The tools provided by the European Molecular Biology Laboratory (EMBL) and the European Bioinformatics Institute (EBI) for local sequence matching use a modified Smith-Waterman algorithm (see www.ebi.ac.uk / Tools / psa / and Smith, TF & Waterman, MS).“Identification of common molecular subsequence” Journal of Molecular Biology, 1981 147 (1):195-197). When performing an alignment, the standard parameters defined by EMBL-EBI are used. These parameters are (i) for amino acid sequences: Matrix = BLOSUM62, gap open penalty = 10 and gap extend penalty = 0.5 or (ii) for nucleic acid sequences: Matrix = DNAfull, gap open penalty = 10 and gap extend penalty = 0.5. It is known to those skilled in the art that, for example, a sequence encoding a protein can be “codon-optimized” if the sequence in question is to be used in a different organism than the one from which the molecule originally came. “Protein percent” or “starch percent” is generally measured by NIR spectrophotometry, but can also be measured using other methods known in the scientific community.

[0048] The term "plant" as used herein includes whole plants, including their offspring or descendants. As used herein, unless explicitly stated otherwise, the term "plant" refers to a plant at any stage of development. The term "plant part" includes any part or derivative of the plant, including certain plant tissues or structures, plant cells, plant protoplasts, plant cells or tissue cultures from which plants can be regenerated, plant calli, plant clumps, and plant cells intact in plants or plant parts, such as seeds, kernels, spadixes, flowers, cotyledons, leaves, stems, buds, roots, root tips, straw, and the like. Plant parts may also include processed plant parts or derivatives, such as flour, oils, extracts, protein fractions, etc. "Plant parts" include, for example, vegetative shoot organs / structures, e.g.,Leaves, stems, and tubers; roots, flowers, and floral organs / structures, e.g., bracts, sepals, petals, stamens, carpels, anthers, and ovules; seeds, including embryo, endosperm, and seed coat; fruits and mature ovaries; plant tissues, e.g., vascular tissue, soil tissue, and the like; and cells, e.g., sentinel cells, ovules, pollen, trichomes, and the like; as well as their offspring.

A "plant cell" is a structural and physiological unit of a plant, comprising a protoplast and a cell wall. The plant cell may be in the form of an isolated single cell or a cultured cell, or as part of a higher organized unit such as a hygroscopic structure.Plant tissue, a plant organ, or an entire plant may be present. "Plant cell culture" means cultures of plant units such as protoplasts, cell culture cells, cells in plant tissues, pollen, pollen tubes, ovules, embryo sacs, zygotes, and embryos at various stages of development. "Plant material" refers to leaves, stems, roots, flowers or flower parts, fruits, pollen, ovules, zygotes, seeds, cuttings, cell or tissue cultures, or any other part or product of a plant. This includes callus or callus tissue, as well as extracts (such as taproot extracts) or samples. A "plant organ" is a distinct and visibly structured and differentiated part of a plant, such as a root, stem, leaf, flower bud, or embryo. "Plant tissue," as used herein, refers to a group of plant cells that form a structural and functional unit.Every tissue of a plant, whether in planta or in culture, is included. This term includes, but is not limited to, whole plants, plant organs, plant seeds, tissue cultures, and all groups of plant cells organized into structural and / or functional units. The use of this term in conjunction with, or in the absence of, a particular type of plant tissue as listed above or otherwise covered by this definition is not intended to imply the exclusion of any other type of plant tissue. In certain embodiments, the plant part is a plant organ, tissue, or cell. In certain embodiments, the plant part is a seed, pollen, ovule, protoplast, inflorescence, embryo, or callus.

Such a modification of a marker may therefore involve shortening or lengthening the marker, as long as the nuclear sequence of at least 10 nucleotides before and after the respective signature mutation or SNP is still present. The development of, for example,KASP markers are known as an example of modified markers that can be individually tailored based on the marker information provided here, depending on the desired screening or selection method.

[0068] In a further aspect, a marker, preferably a set of markers, or the use of a marker or a set of markers is provided that is suitable for screening or selecting a Pisum sativum plant with an improved flavor profile due to at least one signature mutation in at least one gene, preferably a signature mutation as shown in Table 1, including the gene Psat03G0335100, which is involved in the saponin biosynthesis pathway, wherein the marker or set of markers comprises at least SEQ ID NO: 31, or a modified marker thereof, alone or in combination with at least one, at least two, at least three, at least four, at least five, at least six, at least seven or eight markers or more markers as defined in Tables 7 and 8 and above.

[0069] In one embodiment, a plant-based ingredient, preferably a protein ingredient, is provided according to the first aspect, wherein the pea plant comprises at least one signature mutation of at least one nucleotide sequence of a gene that affects saponin biosynthesis in the plant compared to a Pisum sativum reference plant, wherein the gene encodes for and is selected from a cytochrome P450 monooxygenase (P450), a uridine diphosphate (UDP)-dependent glycosyl transferase (UGT), a TSAR transcription factor, a basic leucine zipper (bZIP) transcription factor, or a squalene synthase, including a cytochrome P450 monooxygenase (P450), a uridine diphosphate-dependent glycosyl transferase (UGT), and / or a TSAR transcription factor.

Both varieties are commercially available from KWS Momont SAS, France, and / or KWS SAAT SE & Co. KGaA in Einbeck, Germany. In addition, the ZM6 reference genome, as shown in Table 1, can be used as a reference.

[0073] Seeds of a plant of the Pisum sativum line KWS063 (synonym: KM 17BP063), disclosed herein and detailed in the appended claims, were deposited on April 16, 2024, with the National Collections of Industrial, Food and Marine Bacteria (hereinafter “NCIMB”), Wellheads Place, Dyce, Aberdeen, AB21 7GB, Scotland, United Kingdom, and were granted accession number NCIMB 44382 (see Form BP / 4).

This deposit of KWS063 seed was made under the Budapest Treaty and will be held in the NCIMB vault at least for the duration of the patent's enforceability and will be replaced if the deposit becomes non-viable during that period. Furthermore, the applicant has met all the requirements of sections 1.801 to 1.809 of 37 CFR.fulfilled, including the provision of an indication of the viability of the sample.

[0074] By performing a deep screen and a bioinformatic comparison, the inventors were able to determine that KWS063 carries several signature mutations, i.e., single nucleotide polymorphism (SNP) mutations, that are present in the KWS063 line but not in a reference line compared to the pea reference genome “ZW6” ​​described in the literature, e.g., in Yang, T., Liu, R., Luo, Y. et al. “Improved pea reference genome and pangenome highlight genomic features and evolutionary characteristics”, Nat Genet 54, 1553-1563 (2022).

In some embodiments, the processed vegetable product includes washed and packaged pods and / or seeds (or parts thereof) of KWS063, e.g., in a preserved or frozen form.In other embodiments, the processed vegetable product is a whole pod that has been dehydrated and / or baked.

[0087] In certain cases, peas from KWS063 can be used to produce pea grits or meal. Pea grits or meal produced from KWS063 can also be used to produce pea protein concentrate, pea protein isolate, and any other form of an ingredient obtained or extracted from the peas.

[0088] In another embodiment, peas from KWS063 can be used to produce various types of "fillers" in food products. Examples of foods containing pea-derived products include protein powders, meat-free burgers / minced meat / sausages, beverages with milk alternatives, yogurt alternatives, vegan cheese and puff pastry, and protein bars. The peas from KWS063 can thus be processed to achieve a similar texture and appearance to many other food products.

[0089] Furthermore, the peas from KWS063 can be used in certain embodiments to produce an intermediate, preferably a protein-based intermediate, which is suitable as an additive or filler in a cosmetic composition or product.

[0091] For consumption, i.e., for food and feed, peas from KWS063 can be advantageously used according to the various aspects and embodiments described herein to produce edible protein ingredients that provide a healthier substitute for animal protein in alternative meats, alternative dairy products, beverages, food supplements, and the like. Peas contain approximately 21.2–32.9% protein, 36.9–49% starch, and 14–26% dietary fiber, based on dry weight (for reference values, see, e.g., Geerts, MEJ, et al., “Mildly refined fractions of yellow peas show rich behaviour in thickened oil-in-water emulsions,” Innovative Food Science and Emerging Technologies. (2017). 41: 251–258; Lan, Y., et al., “Solid dispersion-based spray-drying improves solubility and mitigated beany flavour of pea protein isolate,” Food Chemistry. (2019). 278: 665–673; Pietrasik, Z., et al.“Utilization of pea starch and fiber fractions for replacement of wheat crumb in beef burgers,” Meat Science. (October 2019). 161:107974).

[0092] Peas, as legumes, have two aspects that distinguish them from most other food crops. First, they are rich in macro- and micronutrients: they are a good source of protein (rich in essential amino acids such as tryptophan and lysine), slow-digesting carbohydrates, B vitamins, minerals, dietary fiber (soluble and insoluble), phytosterols, and alpha-linolenic acid. They also provide certain amounts of squalene, tocopherols, polyphenols, and triterpenic acids.

[0093] Compared to soybeans or other plant proteins, pea protein is associated with better digestibility and relatively fewer allergenic reactions and negative health controversies.

[0094] However, as described above, there are still challenges in using pea protein as a food ingredient, especially on a large scale, due to organoleptic performance problems, which can be overcome with a pea line of KWS063 or a homologous line.

[0095] In certain embodiments of the provision of a further processed, purified and / or isolated plant-based protein material, the ingredient is in the form of a concentrate, an isolate, a textured product, a powder, a flake or a flour, or the ingredient is a protein, a soluble carbohydrate, an insoluble carbohydrate, a lipid, an ash or a combination thereof, preferably a protein.

[0096] In a further embodiment, the plant or plant part from which the ingredient, preferably an additional plant-based ingredient, for example for use in a hybrid or in an alternative product or composition, is obtained, is selected from a crop plant, including soybeans (Glycine max), beans (Phaseolus spp.), broad bean (Phaseolus vulgaris), fava bean (Vicia faba), mung bean (Vigna radiata), pea (Pisum sativum), chickpea (Cicer arietinum), peanut (Arachis hypogaea), lentil (Lens culinaris, Lens esculenta), lupin (Lupinus spp.), white lupin (Lupinus albus), mesquite (Prosopis spp.), carob (Ceratonia siliqua), tamarind (Tamarindus indica), alfalfa (Medicago sativa), buttercup (Medicago truncatula), and chickweed. (Lotus japonicus), licorice (Glycyrrhiza glabra), clover (Trifolium spp.)), oats, chickpea, kidney bean, maize, potato, wheat, sunflower, rapeseed or rice, wherein the plant or part of the plant from which the ingredient is obtained is preferably a pulse (family Fabaceae, formerly Leguminosae), preferably pea (Pisum sativum), soybean (Glycine max), bean (Phaseolus spp.), including bush bean (Phaseolus vulgaris), and lupins (Lupinus spp.), including white lupin (Lupinus albus).

[0097] A fourth aspect provides a method for producing an alternative consumer product in accordance with the third aspect, comprising: (i) providing a plant-based ingredient or plant-based composition in accordance with the first or second aspect; (ii) adding at least one further additive and / or ingredient; (iii) producing an alternative consumer product.

[0098] In a fifth aspect, the use of a plant-based ingredient or plant-based composition according to one of the first or second aspects for reducing or eliminating off-flavors in an alternative consumer product, preferably in an alternative consumer product as defined in the third aspect, preferably to provide an alternative food, feed or cosmetic composition, optionally in the form of a hybrid product, is provided.

[0099] In a sixth aspect, a method for producing a plant-based ingredient of the first aspect is provided, comprising the following steps: (ia) providing a seed of the plant Pisum sativum with a representative sample of seeds deposited under NCIMB No. 44382, or, where appropriate, a descendant thereof; or (ib) providing a Pisum sativum plant seed with a Psat03G0335100 gene locus exhibiting a signature mutation pattern such as the comparable gene locus in the Pisum sativum plant with a representative sample of seeds deposited under NCIMB No.44382, or a Psat03G0335100 gene locus shown in Table 1, wherein the at least one mutation of the signature mutation pattern is preferably introduced by mutagenesis or genetic engineering, wherein mutagenesis includes chemical mutagenesis, radiation mutagenesis and genome editing, wherein genome editing includes editing by site-specific nucleases, including zinc finger nuclease (ZFN) systems, transcription activator-like effector nuclease (TALEN) systems, meganuclease systems and CRISPR / Cas systems; and (ii) extracting a fraction, including a protein fraction, a starch fraction or a fat fraction, from the pea.

[0100] In one embodiment, the method produces a protein ingredient in the form of a concentrate, an isolate, a textured product, a powder, a flake, or a flour.

[0101] In another embodiment of the method according to the sixth aspect, the extraction step is a dry extraction method or a wet extraction method.

[0102] In a further embodiment, at least one signature mutation or signature mutation pattern can be introduced into another plant, wherein the plant or part thereof is selected from a crop including soybean (Glycine max), beans (Phaseolus spp.), broad bean (Phaseolus vulgaris), fava bean (Vicia faba), mung bean (Vigna radiata), pea (Pisum sativum), chickpea (Cicer arietinum), peanut (Arachis hypogaea), lentil (Lens culinaris, Lens esculenta), lupin (Lupinus spp.), white lupin (Lupinus albus), mesquite (Prosopis spp.), carob (Ceratonia siliqua), tamarind (Tamarindus indica), alfalfa (Medicago sativa), buttercup (Medicago truncatula), chickweed (Lotus japonicus), and licorice (Glycyrrhiza glabra). Clover (Trifolium spp.)), oats, chickpea, kidney bean, maize, potato, wheat, sunflower, rapeseed or rice, preferably wherein the plant or part of the plant from which the ingredient is obtained is a pulse (family Fabaceae, formerly Leguminosae), further preferably pea (Pisum sativum), soybean (Glycine max), bean (Phaseolus spp.), including broad bean (Phaseolus vulgaris), and lupins (Lupinus spp.), including white lupin (Lupinus albus).

[0103] A "site-specific nuclease" in this context refers to a nuclease, or an active fragment thereof, that is capable of specifically recognizing and cleaving DNA at a particular site, the target sequence. Such nucleases typically create a double-strand break (DSB), which is then repaired by non-homologous end joining (NHEJ) or homologous recombination (HR). Site-specific nucleases include meganucleases, homing endonucleases, zinc finger nucleases, transcription activator nucleases, and CRISPR nucleases or variants thereof, including nickases or nuclease-inactivated variants thereof.

[0104] A “CRISPR nuclease,” as used herein, is a specific form of site-directed nuclease and refers to any nucleic acid-directed nuclease identified in a naturally occurring CRISPR system, subsequently isolated from its natural context, and preferably modified or combined into a recombinant construct of interest to be suitable as a tool for targeted genome engineering. Any CRISPR nuclease may be used and, if desired, reprogrammed or further mutated to be suitable for the various embodiments according to the present invention, provided that the original wild-type CRISPR nuclease exhibits DNA recognition, i.e., binding properties. CRISPR nucleases also include mutants or catalytically active fragments or fusions of a naturally occurring CRISPR effector sequence or the corresponding sequences encoding it.A CRISPR nuclease can also refer specifically to a CRISPR nickase or even to a nuclease-inactivated variant of a CRISPR polypeptide that has an endonucleolytic function in its natural environment. A large number of different CRISPR nucleases / systems and variants thereof are now known to those skilled in the art and include, among others, CRISPR / Cas systems, including CRISPR / Cas9 systems (EP2771468), CRISPR / Cpf1 systems (EP3009511B1), CRISPR / C2C2 systems, CRISPR / CasX systems, CRISPR / CasY systems, CRISPR / Cmr systems, CRISPR / MAD systems, including, for example, CRISPR / MAD7 systems (WO2018236548A1) and CRISPR / MAD2 systems, CRISPR / CasΦ systems (Pausch et al., Science, 2020, 10.1126 / science.abb1400), CRISPR / CasZ systems and / or any combination, variant or any 30 catalytically active A fragment of it.A nuclease can be a DNase and / or an RNase, and it is particularly important to consider that certain CRISPR effector nucleases possess RNA cleavage activity alone or in addition to DNA cleavage activity.

[0105] The "guide molecule" or "guide nucleic acid sequence" (usually referred to and abbreviated as guide RNA, crRNA, crRNA+tracrRNA, gRNA, sgRNA, depending on the specific CRISPR system, which is a prototypical nucleic acid-directed site-specific nuclease system) recognizes a target sequence to be cleaved by the nuclease. The guide nucleic acid sequence or "guide molecule" comprises a "scaffold region" and a "target region." The "scaffold region" is a sequence to which the nucleic acid-directed nuclease binds to form a targeted nuclease complex. The scaffold region may include direct repeats that are recognized and processed by the nucleic acid-directed nuclease to form mature crRNA. A pegRNA may include an additional region within the guide molecule called the "primer-binding site." The "target region" defines the complementarity to the target area that is to be divided.A crRNA, as used here, can therefore be used interchangeably with the term guide RNA if it combines the effects of the now well-established CRISPR nuclease guide RNA functionalities. Certain CRISPR nucleases, e.g., Cas9, can be used by providing two individual guide nucleic acid sequences in the form of a tracrRNA and a crRNA, which may be separate or linked via covalent or non-covalent bonds / interactions. The guide RNA may also be a pegRNA of a prime-editing system. The at least one guide molecule may be provided as a single molecule or the sequence encoding it, or as two separate molecules, e.g., crRNA and tracrRNA or the sequences encoding them.

[0106] In certain embodiments, a donor plant or a donor plant population comprising one or more alleles associated with an improved trait according to the present invention can be crossed with a recipient plant or a recipient plant population, such as a plant from an elite line or any plant of interest, to introduce one or more alleles associated with an improved trait into the recipient plant or plant population, e.g., as part of a breeding program. The method according to the invention can be used to identify one or more offspring from such crosses that exhibit an improved trait.

[0107] In certain embodiments, the plants, preferably the peas, produced from these selected plant lines or varieties, preferably pea lines, have a lower or altered saponin content and therefore exhibit less off-flavor perception compared to peas from plants in which the expression of one or more genes of the biosynthesis pathway is not reduced, significantly reduced, or eliminated. The selected pea plants are cultivated, and the peas can be harvested from these plants. The protein ingredient can be extracted from the harvested peas, resulting in a pea protein ingredient that exhibits less off-flavor compared to a control (or reference) pea protein ingredient produced from peas in which the expression of one or more of these genes is not altered (hereinafter referred to as "control peas").

[0108] In certain aspects and embodiments of the method of the sixth aspect, the provision of at least one Pisum sativum plant seed with a Psat03G0335100 gene locus exhibiting a signature mutation pattern as the comparable gene locus in the Pisum sativum plant that has a representative sample of seeds deposited under NCIMB No. 44382, or a Psat03G0335100 gene locus shown in Table 1, can be achieved by using a reference or control plant that does not carry the at least one signature mutation or signature mutation pattern of the present invention, and by using a knockdown RNAi construct based on the SNP mutations shown, among others, in Table 1 to temporarily reduce the transcription of a gene in the saponin pathway in order to achieve a phenotype of reduced off-flavor of the present invention.

[0109] Details of the invention are described in more detail in the following non-limiting examples. EXAMPLES Example 1A: Sensory evaluation of peas: Experimental setup

[0110] Sensory investigations were carried out on peas, pea protein isolates and alternative milk drinks containing such pea protein isolates.

[0111] The sensory dimensions included appearance, aroma, taste, mouthfeel, and aftertaste, and each attribute is summarized in Table 2: TABLE 2 dimension attribute from until definition appearance Color intensity bright dark Measurement of the color intensity of the sample. Particles (on glass) few many Measuring the number of particles on the glass. foam few much Measurement of the product's foam. aroma Total intensity few intensive Measurement of the overall intensity of the product, including all perceptions. pea few intensive Measurement of the intensity of the pea aroma.

[0112] The differences in the various attributes were examined for statistical significance using an analysis of variance (mixed ANOVA) to determine whether the products differed significantly based on an attribute. For the mixed ANOVA, an anchor product is a fixed factor, and the tested products are the random factors, yielding the estimated means and the "least significant difference" (LSD). The LSD represents the minimum difference required, expressed as a scale distance between two products, to conclude that they are significantly different (Fischer's LSD 95%). "Descriptor discrimination" (DD) indicates how often the LSD "fits" into the highest and lowest intensity values ​​of the products. If the DD is greater than 1, the attribute is significantly discriminating between the products. Example 1A: Sensory evaluation of peas: Test

[0113] 20 g of cooked and pureed peas from the pea line KWS063, containing a representative sample of the seeds deposited under NCIMB No. 44382, were evaluated in comparison to cooked and pureed peas of the commercial pea varieties Flam and Kameleon, available from KWS SAAT SE & Co. KGaA in Einbeck, Germany. A trained sensory panel assessed the peas for aroma, mouthfeel / texture, and aftertaste. The results of the evaluation are presented in Tables 3a and 3b, as well as in Fig. depicted. TABLE 3a: Raw Score Analysis: Pea Puree Attribute: Flame KWS063 LSD DD Taste - Bitter 2.309090909 1.663636364 0.404015202 1.59759965 Taste - Sweet 1.731818182 2.5 0.453049358 1.695580856 Taste - Sour 1.586363636 1.277272727 0.248184676 1.245406904 Mouthfeel - Powdery 2.927272727 2.213636364 0.402093456 1.774802231 Mouthfeel - Dull 2.504545455 2.122727273 0.336244053 1.135538839 Mouthfeel - Coated 2.954545455 2.568181818 0.336273798 1.148955521 Aftertaste - bitter 2.068181818 1.640909091 0.384529342 1.111157669 TABLE 3b: Analysis of mean scores: Pea puree Attribute: Flame KWS063 LSD DD Taste - Bitter 0 -0.645454545 0.404015202 1.59759965 Taste - Sweet 0 0.768181818 0.453049358 1.695580856 Taste - Sour 0 -0.309090909 0.248184676 1.245406904 Mouthfeel - Powdery 0 -0.713636364 0.402093456 1.774802231 Mouthfeel - Dull 0 -0.381818182 0.336244053 1.135538839 Mouthfeel - Coated 0 -0.386363636 0.336273798 1.148955521 Aftertaste - bitter 0 -0.427272727 0.384529342 1.111157669

[0114] The results of the mean score analysis comparing statistically significant distinguishing features are in Fig.1 graphically represented. These data indicate an improved mouthfeel and taste, as well as a lower overall bitterness and bitter aftertaste, which are attributed to the peas of KWS063 compared to the peas of the control variety Flam. Example 2: Sensory evaluation of the protein isolate extracted from peas

[0115] 50 g of protein isolate powder from peas of the pea line KWS063, containing a representative sample of the seeds deposited under NCIMB No. 44382, were analyzed for their sensory properties in comparison to a protein isolate obtained from a commercially available pea variety, Kameleon. A trained sensory panel evaluated 5% protein isolate solutions prepared by combining the protein isolate powders with 1000 mL of water. The results of the evaluation are presented in Table 4.

[0116] The results of the mean score analysis show a reduction in the aroma, taste, and aftertaste attributes listed in Table 1 for the protein isolate extracted from peas of KWS063 compared to a protein isolate extracted from peas of the commercial variety Kameleon. The results of the mean score analysis show a reduction in the aroma, taste, and aftertaste attributes listed in Table 4 for the protein isolate extracted from peas of KWS063 compared to a protein isolate extracted from peas of the commercial variety Kameleon. Example 3: Sensory evaluation of the alternative milk drink vly™

[0117] 200 g of a protein isolate, as described in Example 2, were combined with 8,000 mL of a commercially available alternative milk base formula provided by VF Nutrition GmbH, trading as vly™, in Berlin, Germany. A trained sensory panel of 10 participants evaluated the alternative milk drink for its sensory properties, including those listed in Table 5 and in Fig. The aroma, taste, and aftertaste attributes shown are compared to the same alternative milk-based formulation produced using a commercially available Flam protein isolate.

[0118] The results of the mean score analysis comparing statistically significant distinguishing features are in Fig.Figure 2 is shown graphically. These data indicate a significantly improved aroma and taste, as well as a lower and less intense bitter aftertaste, attributed to the peas from KWS063 compared to the peas of the commercial variety Flam.

[0119] Although several possible embodiments have been disclosed above, the embodiments of the present invention are not so limited. These exemplary embodiments are not intended to be exhaustive or to unnecessarily restrict the scope of the invention, but were selected and described to illustrate the principles of the present invention so that other people skilled in the art can apply it. Indeed, various modifications of the invention beyond those described herein will be apparent to those skilled in the art from the preceding description. Such modifications are intended to fall within the scope of the appended claims. Example 4: In-depth evaluation of candidates

[0120] Individual candidates influencing the saponin pathway in the pea were then analyzed in more detail in the relevant germplasm of interest and in various comparison lines.

[0121] It is striking that many Pisum sativum candidate genes, which have been shown to be involved in the saponin biosynthesis pathway, exhibit only a low degree of identity with homologs / orthologs / paralogs in other cultivated varieties. This is exemplified for the TSAR genes of Pisum sativum in Table 6, which shows that it is almost impossible to extrapolate results from different cultivated plants to Pisum sativum candidate genes, as the genes, including TSAR1, TSAR2, and TSAR3, typically exhibit a very low degree of sequence identity. TABLE 6: Exemplary sequence comparison Query and Gene Description Maximum score Total score Query Coverage E-value Percent.Identity Access Psat03G0335100-T1TSAR1 ChenopodiumquinoaCropRegalonachromosome 6B 65,1 719 45% 8.00E-10 34,75% CP135428.1 Psat04G0244300-T1TSAR2 ChenopodiumquinoaCropRegalonachromosome 6B 60,5 697 51% 5.00E-17 48,28% CP135428.1 Psat04G0244200-T1TSAR3 ChenopodiumquinoaCropRegalonachromosome 6B 59,7 796 50% 7.00E-08 50,00% CP135428.1

[0122] This revealed that signature mutations of interest must be identified and evaluated on a case-by-case basis, as it is neither meaningful nor successful to extrapolate the results directly from other cultivated varieties. Example 5: Development and application of genetic fingerprint marker sets for identification

[0123] Fingerprint markers were developed for screening for signature mutations and selecting relevant plant material. This development involved analyzing whole-genome sequencing data from the lines in question. The specificity of these markers lies in the careful selection of variants with very low allele frequencies. For a given sample size, these alleles were observed with a frequency of less than or equal to 0.01, meaning they are almost exclusively present in the specified lines. This proves to be an effective method for establishing identity, as it considers the combined probabilities of the observed markers at their respective allele frequencies.

[0124] The application of the marker set for identity determination consists of sequence analyses in the genome regions, regardless of the technology, along each of the different physical positions in the genome, 12 different physical positions for lineage 17BP063, which was deposited under NCIMB No. 44382.

[0125] In order to establish the identity of each line, for each given sequence position with a questionable variant of the reported marker set, the observed allele must match that of the designated SNP assigned to the respective line; only queries with 100% matching genotype calls at each of the given marker positions will be found to have an identity for 17BP063.

[0126] A detailed explanation is given in Table 7, where light gray cells correspond to matching genotype calls and thus characterize SNP signature marker positions between a queried individual and the corresponding genotype calls observed for line 17BP063, deposited under NCIMB No. 44382. Dark gray cells (and bold and underlined nucleotides of the signature SNP position) indicate discrepancies in the genotype calls that lead to loss of identity.

[0127] FP01 to FP11 in Table 7 correspond to SEQ ID NO: 20 to 30.

[0128] If one wishes to enter the production of food ingredients by using germplasm with the advantageous properties and signature mutations of the present invention for downstream (product / food) production, the quality checks can be carried out as follows: Typically, one starts with a high-quality reference line that exhibits a phenotype to be improved (or that a customer wishes to have improved). The material is then incorporated into internal routine research as a reference framework for improvements.

[0129] For this purpose, three samples from genetic stocks are typically submitted for inclusion in breeding plans for future generations. Analysis of the stocks in question allows for the identification of lines based on genomic similarities, as revealed here, and enables more in-depth screening using fingerprint marker sets, e.g., as shown in queries 1-3 in Table 7.

[0130] In the example shown in Table 7, direct comparisons of the observed with the expected genotype calls revealed that one sample, query 2, has a 100% genotype call match with NCIMB line No. 44382, i.e., 11 / 11 marker match.

[0131] For intelligent and fast screens, fewer markers are sufficient, but usually at least two markers are needed to clearly identify a mismatch.

[0132] This approach allows for the direct identification of the genetics underlying NCIMB No. 44382 material and the material derived from it, combined with a functional test for an enhanced taste profile based on the genetics of NCIMB No. 44382.

[0133] A party interested in developing pea-derived material with improved flavor properties, utilizing the deposited lines and teachings contained therein, may wish to implement a protocol for the production of an alternative milk ingredient. To ensure the necessary diligence, it must be ensured that the relevant lines undergo routine quality control before mass production and protocol implementation. This involves first establishing the genetic identity of the material in the production facilities by sampling several production batches, e.g., queries 1-3 in Table 7.

[0134] After testing more than 30 independent fingerprint markers using a preferred genotyping platform, we were able to directly compare the expected and observed genotype calls at each position for each of the samples, all based on material 17BP063, which has previously been confirmed to contain significant SNPs in the saponin biosynthesis pathway that positively influence taste. After careful evaluation of all 30 independent fingerprint markers, we found that while there are similarities between several of the expected genotype calls from the different production batches and the reference frame, including a TSAR1 marker that is highly specific for one of the taste-enhancing signature mutations in the 17BP063 line, none of the three random samples exhibited the exact same genotype calls as the expected alleles across all markers.Based on these observations, we can discard germplasm from queries 1 and 3 to ensure that all genetic stocks used for mass production and protocol implementation have the same genetic basis as a starting point for their expected phenotypic performance.

[0135] The respective best-performing markers FP_01 to FP_11 (SEQ ID NO: 20 to 30) are highly specific and clearly detect 17BP063 material alone or in suitable combinations and can be used for screening pea lines together with the other markers listed below. TABLE 7: SNP signature mutations within NCIMB No. 44382 MARKER Relevant Genotype Position Query 1 Query 2 Query 3 17BP063_FP_01 A A A A 17BP063_FP_02 T C T T 17BP063_FP_03 A A A A 17BP063_FP_04 C G C C 17BP063_FP_05 G G G G 17BP063_FP_06 T T T T 17BP063_FP_07 A G A A 17BP063_FP_08 C C C C 17BP063_FP_09 A A A T 17BP063_FP_10 C T C C 17BP063_FP_11 T T T T 17BP063_TSAR1 G G G A identity 17BP063NCIMB-No.44382 Not determined 17BP063 Nichtfestgestellt

[0136] Subsequently, further candidates that directly and indirectly influence the saponin biosynthesis pathway were screened. Pisum sativum TSAR 1 to 3 (SEQ ID NO: 1 to 9), Pisum sativum alpha-1,2-mannosyltransferase (SEQ ID NO: 10 and 11), two variants of Pisum sativum cytochrome P450 72A68-like (SEQ ID NO: 12 to 15), Pisum sativum terpene cyclase (SEQ ID NO: 16 and 17), and Pisum sativum specific beta-amyrin synthase (BAS, SEQ ID NO: 18 and 19) were examined in the corresponding 17BP063 material, which is deposited under NCIMB No. 44382, because mutations were identified that have an impact on the plant's flavor profile at the phenotypic level.

[0137] In particular, certain SNP signature mutations, as shown in Table 8 below, were identified, and markers were designed and tested (SEQ ID NO: 31 to 40) which, alone or in combination, enable the identification of material with a favorable signature mutation.

[0138] The above results show that, based on the analysis of the genome of 17BP063, deposited as NCIMB No.44382 relevant genotypic and phenotypic insights were gained that apply to the specific line, but also beyond: Generally applicable SNP signature mutations and genotype positions were identified that are important for the identification and characterization of pea plants with an improved taste profile that is useful for a variety of food applications, whereby it was shown that signature mutations in at least one gene or a non-coding region thereof that are directly or indirectly involved in the saponin biosynthesis pathway are very characteristic for quickly and efficiently identifying pea plants for the production of plant-based ingredients with an attractive and improved taste compared to plants that do not carry the relevant mutations.

[0139] Interestingly, a mutation in the TSAR1 gene was identified that significantly affects the saponin biosynthesis pathway and, conversely, leads to a lower content of off-flavors in the plant material in question. This marker is therefore a suitable tool for screening for comparable mutations in pea germplasm. QUOTES INCLUDED IN THE DESCRIPTION
