摘要: 真核细胞通过胞吞和胞吐作用将大分子和颗粒性物质运出或运送至质膜, 其中包括一些具有重要生物学功能的蛋白质。胞吞和胞吐途径之间的耦合对维持质膜的完整性以及调控质膜蛋白的丰度和活性至关重要。动物中, 突触小泡的胞吞和胞吐在时空上紧密耦合已被证明是持续神经传递的必要条件。近年来, 随着对植物囊泡运输的深入研究, 越来越多的证据表明, 植物细胞的胞吞和胞吐间同样存在耦合调控, 且在植物生长发育和对外界环境的响应中扮演重要角色。该文综述了植物协同调控胞吞和胞吐的生理学意义, 并结合网格蛋白介导囊泡运输的最新研究进展探讨了其可能的耦合机制。

Abstract: Eukaryotic cells transport macromolecules and particulate matter away or to the plasma membrane through endocytosis and exocytosis, including certain proteins with important biological functions. The coupling between these two vesicle transport pathways is essential for maintaining the integrity of the plasma membrane as well as regulating the abundance and activity of plasma membrane proteins. In animals, the spatiotemporal coupling of synaptic vesicle endocytosis and exocytosis has been shown to be necessary for the continuation of neurotransmission. In recent years, increasing evidences on the plant vesicle trafficking show the existence of a coupling regulation between endocytosis and exocytosis, which plays an important role in plant growth and development as well as responses to the environment. Here we summarize the physiological significance of plant cooperative regulation of endocytosis and exocytosis, and discuss the potential coupling mechanisms based on the recent progress in the study of clathrin-mediated vesicle trafficking.
