BiFC interactions in tobacco leaf epidermal cells. A: PI-PLC1-CYFP and PI-PLC1 -NYFP dimerization on ER and PM; B:co-localization of GA3-Q223L-CYFP and PI-PLC1-NYFP interaction to ER; C:co-localization of GA3-Q223L-CYFP and PI-PLC1-NYFP to PM; Twenty cells of GA3-Q223L-CYFP and PI-PLC1-NYFP BiFC interaction have higher YFP flourecent compered to GA3-CYFP and PI-PLC1-NYFP BiFC interaction; D:the localization of the interaction between the two PI-PLC1-CYFP and Clo3-NYFP apparent by ER network structure seen in the upper focal planes of the cell.
