Oil Deposition

Research output: Chapter in Book/Report/Conference proceedingEntry for encyclopedia/dictionarypeer-review


The seed storage oils of higher plants are principally deposited in the cytosol as numerous small triacylglycerol-rich lipid droplets bounded by a specific annulus of proteins of which the oleosins are the main components. Triacylglycerols are assembled in the endoplasmic reticulum from fatty acids synthesized de novo in plastids and a glycerol backbone. Once released from the endoplasmic reticulum as cytosolic lipid droplets, some further acyl modification may occur. Seed oils have many practical uses as foodstuffs and for numerous industrial applications, and there is considerable biotechnological interest in the manipulation of fatty acid content in oilseed crops.
