Figure 3

A C-terminal peripheral PM-binding domain is required for ER-PM tethering by Arabidopsis SYT1 in N. benthamiana leaf cortical cells. (A) Explanatory schematic of reconstitution of SYT1 ER-PM tethering using BiFC complexes. (B,C) Distribution and kymograph analysis of full length SYT1 or SYT1 reconstituted using Venus BiFC complexes. (D,E) Distribution and kymograph analysis of SYT1 lacking the C-terminal peripheral PM-binding domain C2AC2B labeled by either full-length YFP or a free Venus BiFC complex. (F,G) Distribution and kymograph analysis of SYT1n fused to WT-type StRem1.3 or PM-non-binding mutant StRem1.3* via Venus BiFC complexes. All kymographs were created as described in Figure 2. All scale bars represent 10 μm.
