Abstract

In all eukaryotic cells, a membrane trafficking system connects the post-Golgi organelles, including the trans-Golgi network (TGN), endosomes, and vacuoles. This complex network plays critical roles in several higher-order functions in multicellular organisms. The TGN, one of the important organelles for protein transport in the post-Golgi network, functions as a sorting station, where cargo proteins are directed to the appropriate post-Golgi compartments. The TGN has been considered to be a compartment belonging to the Golgi apparatus, located on the trans side of the Golgi apparatus. However, in plant cells, recent studies have suggested that the TGN is an independent, dynamic organelle that possesses features different than those of TGNs in animal and yeast cells. In this review, we summarize recent progress regarding the dynamics and physiological functions of the plant TGN.
