摘要：

Plant seeds store triacylglycerols in intracellular oil bodies as food reserves for germination. Each spherical oil body has a diameter of about 0.5-2.0 mu m, and consists of a triacylglycerol matrix surrounded by a layer of phospholipids embedded with abundant and unique proteins called oleosins. Oleosins have special secondary structures which interact with the surface phospholipid layer and the matrix triacylglycerols. They stabilize the oil bodies and possibly serve as recognition signals for lipase binding during seed germination.
