Method of increasing the fatty acid content in plant seeds

摘要

The invention relates to nucleic acid molecules that encode a protein with the activity of a beta-ketoacyl-ACP synthase IV (KASIV) from Cuphea lanceolata, to nucleic acid molecules that encode a protein with the activity of a beta-ketoacyl-ACP synthase II (KASII) from Brassica napus, and to nucleic acid molecules that encode a protein with the activity of a beta-ketoacyl-ACP synthase I (KASI) from Cuphea lanceolata. The invention further relates to a method of increasing the content of fatty acids, especially of short- and medium-chain fatty acids in triglycerides of plant seeds. The inventive method comprises expressing a protein with the activity of KASII or a protein with the activity of KASIV in transgenic plant seeds.
