囊泡的胞吐和胞吞作用控制细胞表面信号触发或减弱所需的质膜蛋白的活性和周转。近年来，人们发现植物中存在多种胞吐和胞吞转运途径。常规和非常规蛋白质分泌之间的平衡提供了应对应激条件的有效策略。类似地，网格蛋白依赖性和非依赖性内吞作用协同调节膜蛋白响应环境线索的动力学。事实上，植物生长和发育的许多方面，如顶端生长、免疫反应和蛋白质极性的建立，都涉及外吞-内吞运输的紧密部署。然而，我们对它们的交叉点的理解是有限的。本文主要讨论了植物胞吐-胞吞转运的分子调控机制以及胞吐-胞吞平衡的生物学意义。
Vesicle exocytosis and endocytosis control the activities and turnover of plasma membrane proteins required for signaling triggering or attenuating at the cell surface. In recent years, the diverse exocytic and endocytic trafficking pathways have been uncovered in plants. The balance between conventional and unconventional protein secretion provides an efficient strategy to respond to stress conditions. Similarly, clathrin‐dependent and ‐independent endocytosis cooperatively regulate the dynamics of membrane proteins in response to environmental cues. In fact, many aspects of plant growth and development, such as tip growth, immune response, and protein polarity establishment, involve the tight deployment of exo–endocytic trafficking. However, our understanding of their intersection is limited. Here, we discuss recent advances in the molecular factors coupling plant exo–endocytic trafficking and the biological significance of balance between exocytosis and endocytosis in plants.
