methods and compositions for the synthesis of long-chain, polyunsaturated fatty acids in plants.

摘要

Nucleic acid construct contains: (a) at least one of 1617 (S1), 1488 (S2) and 1488 (S3) bp sequences (I), or (b) any sequence encoding the same proteins as (I), coupled to a heterologous sequence, particularly an expression control sequence functional in plants. Also new are: (A) recombinant plant cells containing at least one DNA encoding a Mortierella alpina fatty acid desaturase (FAD), so that it can produce a polyunsaturated fatty acid (PUFA); (B) oils produced by these cells (or plants containing them), and (C) 7 sequences encoding human FAD and two sequences encoding Schizochytrium FAD, when expressed in plant cells.
