| 摘要 |
The invention relates to mutated sequence of nucleic acid, coding enzyme delta-12- phosphatidylcholinedesaturase from plant, wherein the mentioned mutated sequence of nucleic acid contains nonconservative mutation of at least one nucleotide of at least one codon, representing amino acid, selected from the group, comprising: amino acid in position 259 of amino acid sequence of the mentioned FAD2, when the sequence consists of 384 amino acids, or in position 258, when FAD2 sequence consists of 383 amino acids. The invention also relates to the nucleic acid, which is homological, complementary or heteroduplex towards the mentioned mutated sequence of nucleic acid, and to the plants, containing the mentioned sequences. The mentioned mutated sequence of nucleic acid provides increased content of oleic acid in plants, containing it. |
