摘要
By contrast to other eukaryotic kingdoms, plant cytokinesis is an inside-out process. A coordinated action of cytoskeletal transitions and endomembrane trafficking events builds a novel membrane compartment, the cell plate. Deposition of cell wall polymers transforms the lumen of this membrane compartment into a new cross wall, physically separating the daughter cells. The characterization of tethering complexes acting at discrete phases during cell plate formation and upstream of vesicle fusion events, the presence of modulators directing secretion and recycling during cytokinesis, as well as the identification and temporal recruitment of the endocytic machinery, provides a starting point to dissect the transitions in endomembrane trafficking which shape this process. This review aims to integrate recent findings on endomembrane trafficking events which spatio-temporally act to construct the cell plate.
