Oilseed rape (Brassica napus) is an important crop that is cultivated for the oil (mainly triacylglycerol; TAG) it produces in its seeds. TAG synthesis is controlled mainly by key enzymes in the Kennedy pathway, such as glycerol 3-phosphate acyltrans...

De novo fatty acid synthesis in plants occurs primarily in the plastids and is catalysed by a type-II fatty acid synthase (FAS) in which separate enzymes catalyse sequential reactions. Genes encoding all of the plant FAS components have been identifi...
