Abstract

The post-Golgi traffic network in plant cells is highly complex, which is correlated with the large number of genes related to this function. RABs and SNAREs are key regulators of tethering and fusion of transport vesicles to target membranes, and the numbers of these regulators have also expanded in plant lineages. In addition to this increase in the net number of genes, plants also seem to have evolved new gene families tailored to fulfill plant-unique functions. In this article, we summarize recent progress in studies on plant-unique RABs and SNAREs functioning in post-Golgi trafficking, with a special focus on the endocytic pathway.
