| Outline of Final Research Achievements |
The trans-Golgi network (TGN) functions as a sorting station that directs cargo proteins to a variety of destinations including post-Golgi compartments and the extracellular space. However, the functions and dynamics of the TGN in plant cells have remained unknown. To reveal the dynamics of the plant TGN, transgenic plants expressing GFP-SYP43 as a TGN marker was observed. Observations revealed that there are two types of TGN in Arabidopsis root: the GA-TGNs (Golgi-associated TGNs), located on the trans-side of the Golgi apparatus, and the GI-TGNs (Golgi-released independent TGNs), located away from the Golgi apparatus and behaving independently. The GI-TGNs is segregated from the GA-TGNs. I also found that the number of the GI-TGNs are different among observed tissues.
