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.

Key words: sclathrin, coupling, endocytosis, exocytosis
