Vacuole Biogenesis in Plants
Chapter in an edited book (author)


摘要The vacuole in plant is a membrane-bound organelle that essentially functions in multiple biological processes such as protein turnover, material storage, cellular homeostasis and defense. Two major types of vacuoles, the lytic vacuoles (LVs) and protein storage vacuoles (PSVs), exist in plants with different morphological properties, functions and biogenesis mechanisms. Most proteins located on the lytic vacuole membrane are transported through the conserved secretory pathway from the endoplasmic reticulum (ER) to the Golgi apparatus, further sorted at the trans-Golgi network (TGN), and delivered to the prevacuolar compartment (PVC) and then the vacuole. Alternatively, proteins could be transported through ER-to-vacuole, Golgi-to-vacuole and cytoplasma-to-vacuole pathways. For the plant unique PSVs, proteins are transported in distinct pathways including the dense vesicles, clathrin-coated vesicles, precursor-accumulating vesicles, and autophagy-mediated trafficking. Compared to the well-characterized molecular basis of protein trafficking to the vacuole, the knowledge of the vacuolar membrane origins is limited. Recent evidences showed that both the PVC and ER contribute to the vacuole biogenesis, while more progresses are expected with the rapid development of advanced techniques. In this book chapter, we presented an updated introduction about the plant vacuoles regarding the trafficking and biogenesis mechanisms.
