Abstract:

Oil bodies, also known as lipid droplets or oil droplets, are important organelles for oil storage in plant cells. The oil body is composed of a monolayer of phospholipid membrane encapsulating neutral fatty acids, and a variety of membrane proteins are embedded in the membrane, including oleosin, caleosin and steroleosin, of which oleosin accounts for 80%-90%. Oleosin plays important biological roles in various biological roles, such as affecting the size and stability of oil bodies, formation and degradation of oil bodies, lipid metabolism, and seed maturation and germination. In this review, we summarize the sequence and structural characteristics of oleosin and its important role in plant growth and development based on the research progress of plant oleosin gene families at home and abroad in recent years. Additionally, we discuss the application of oleosin in actual production and problems in the research and application, in order to provide a useful reference for people to further study the functions of oleosin-related molecules and their application in production practice.

Key words: oil body, oleosin, oil body stability, lipid metabolism, lipid synthesis
