This invention relates to nucleic acid sequences coding for aorfatty acid elongase, yeast cells expressing the genes/enzymes, plants themselves and cells of such plants and seeds which contain a heterologous gene coding for aorfatty 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.

[object Object]

A diacylglycerol acyltransferase (DGAT1) gene fromencodes a DGAT1 polypeptide that regulates the production of triacylglycerols from diacylglycerols. Transformation of cells with theDGAT1 (TmDGAT1) gene, or variants thereof, leads to changes in DGAT1 activity and alterations in oil and/or fatty acid content and/or seed weight. In particular, oil content, seed weight, erucic acid and/or trierucin content may be increased.
