摘要:
This invention relates to seeds of plant, plants themselves and cells of such plants which comprise a heterologous gene coding for a plant (such as nasturtium (Tropaeolum majus) or Crambe abyssinica) fatty acid elongase (FAE) gene or allelic variant thereof, or combinations of one or both of these FAE genes with an Arabidopsis fatty acid elongase 1 (FAE1) gene, in co-transformation, in reading frame alignment with a promoter capable of increasing expression of said gene(s), when said transformed plant cell is in a seed, said plant cell or seed being capable of producing an increase in proportion of a very long chain monounsaturated or saturated fatty acids when compared with the proportions of said fatty acids in a control plant cell or seed lacking said heterologous FAE gene or genes. The invention also relates to combinations of these fatty acid elongase genes by traditional crossing, sufficient to increase the proportion of very long chain monounsaturated or saturated fatty acids in the seed oil of the progeny compared to the proportion of said fatty acids in either of the parental lines.

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

摘要:
This invention relates to the modification of plant lipids and seed oils by genetic engineering techniques to produce oilseeds of enhanced commercial value. In one form, the invention relates to a transgenic oilseed plant, or a seed of such plant, having a genome incorporating an expressible yeast SLC1-1 or SLC1 gene. The invention also provides a method of producing a transgenic oilseed plant, which comprises introducing into the genome of the plant an expressible yeast SLC1-1 or SLC1 gene. The invention also relates to various plasmids and vectors used in the method of the invention.
