Abstract: The present invention is based on the finding that stearin fats, obtainable by dry or solvent fractionation of sunflower high-stearic and high-oleic oils, optionally with seeding with tempered stearin crystals, have a high solid fat content at temperatures higher than 30° C., even higher than cocoa butter or other high saturated tropical fats with a similar disaturated triacylglycerol content due to the presence of disaturated triacylgiycerols rich in stearic acid, and improved melting point due to the presence of arachidic and behenic acids in these disaturated triacylgiycerols, being at the same time healthier that actual fats made from palm, palm kernel and coconut oils, or hydrogenated and trasesterified vegetable oils.

Abstract: The invention relates to nucleic acid derived from Perkinsus marinus which encodes a 9-elongase, a ?8-desaturase and a ?5-desaturase enzyme. All of the coding sequences can be transcribed as a single transcript.

Abstract: The present invention relates to the production of ?-linolenic acid (18:3?6,9,12) or stearidonic acid (18:4?6,9,12,15) or ?-linolenic acid (18:3?6,9,12) and stearidonic acid (18:4?6,9,12,15) in transgenic plants of the family Brassicaceae, where the transgenic plants comprise at least 10% by weight of oleic acid based on the total fatty acid content and, as the result of the activity of the ?6-desaturases used in the method, have an increased ?6-C18-fatty acid content. The invention furthermore relates to novel nucleic acid sequences which code for the ?6-desaturases used in the method, gene constructs comprising these nucleic acid sequences, a vector and transgenic plants comprising at least one nucleic acid sequence or a gene construct.
