process for producing eicosapentaenoic acid, docosapentaenoic acid and / or docosahexaenoic acid in a transgenic plant, nucleic acid molecule, transgenic plant, and use of oils, lipids or free fatty acids

摘要

PROCESS FOR PRODUCING EICOSAPENTAENIC ACID, DOCOSAPENTAENIC ACID AND / OR DOCOSAUEXAENIC ACID IN A TRANSGENIC PLANT, NUCLEIC ACID PLANT, AND USE OF OILS, LIPID OR GRAPHIC OILS. The invention relates to a process for producing eicosapentaenoic acid, docosapentaenoic acid and / or docohexanoic acid in transgenic plants. According to said process, the plant is provided with at least one nucleic acid sequence encoding a polypeptide with an activity. of 30 6 desaturase, at least one nucleic acid sequence encoding a polypeptide with an activity of 30 elongase, at least one nucleic acid encoding a polypeptide with an activity of 30 5 desaturase, and At least one nucleic acid sequence encoding a polypeptide with an activity of 30 elongase, the nucleic acid sequence encoding a polypeptide with an activity of 30 elongase being modified relative to the nucleic acid sequence in the organism. from which the sequence originates, such that it is adapted for codon use in at least one type of plant. of docosahexanoic acid, at least one nucleic acid sequence encoding a polypeptide with an activity of ≤4 desaturase is also introduced into the plant.
