Zusammenfassung:The invention relates generally to methods and compositions concerning desaturase enzymes that modulate the number and location of double bonds in long chain poly-unsaturated fatty acids (LC-PUFA's). In particular, the invention relates to methods and compositions for improving omega-3 fatty acid profiles in plant products and parts using desaturase enzymes and nucleic acids encoding for such enzymes. In particular embodiments, the desaturase enzymes are Primula ?6-desaturases. Also provided are improved soybean oil compositions having SDA and a beneficial overall content of omega-3 fatty acids relative to omega-6 fatty acids. La invencion se refiere en general a metodos y composiciones que se refieren a enzimas desaturasa que modulan el numero y la ubicacion de enlaces dobles en acidos grasos poliinsaturados de cadena larga, LC-PUFA's; en particular, la invencion se refiere a metodos y composiciones para mejorar el perfil de acidos grasos omega-3 en productos y partes de plantas usando enzimas desaturasa y acidos nucleicos que codifican para dichas enzimas; en modalidades particulares, las enzimas desaturasa son ?6 desaturasas de Primula; se proveen tambien composiciones de aceite de soya mejoradas que tienen SDA y un contenido general benefico de acidos grasos omega-3 respecto a acidos grasos omega-6.
