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.
油体，也称为脂质体或油滴，是植物细胞中储存油脂的重要细胞器。油体由单层磷脂膜包裹中性脂肪酸组成，多种膜蛋白嵌入膜中，包括油质蛋白、钙蛋白和甾醇蛋白，其中油质蛋白占 80%-90%。油质蛋白在各种生物学作用中发挥着重要的生物学作用，例如影响油体的大小和稳定性、油体的形成和降解、脂质代谢以及种子成熟和萌发。在本文中，我们根据近年来国内外植物油质蛋白基因家族的研究进展，总结了油质蛋白的序列和结构特征及其在植物生长发育中的重要作用。此外，我们还讨论了油质蛋白在实际生产中的应用和研究应用中存在的问题，以期为进一步研究油质蛋白相关分子的功能及其在生产实践中的应用提供有益的参考。
