LUNARIA ANNUA, CARDAMINE GRAECA AND TEESDALIA NUDICAULIS FAEGENES AND THEIR USE IN PRODUCING NERVONIC AND EICOSENOIC ACIDS IN SEED OILS

摘要

This invention relates to nucleic acid sequences coding for aLunaria annu a, Cardamine graeca or Teesdalia nudicaulis fatty acid elongase, yeast cells expressing the genes/enzymes, plants themselves and cells of such plants an d seeds which contain a heterologous gene coding for a L. annua, C. graeca o r T. nudicaulis fatty acid elongase gene, the plant or seed being capable of producing increased proportion of a very long chain monounsaturated fatty a cid, especially nervonic acid and eicosenoic acid, beyond that of a control plant or seed lacking the heterologous FAE gene or genes.
