Identification of the interaction between V2 and V1 proteins. (A) Co-IP analysis of the interaction between FLAG-V2 and V1-YFP. N. benthamiana leaves were co-infiltrated with FLAG-V2 and V1-YFP (Lane 1), FLAG-V2 and YFP (Lane 2), or V1-YFP alone (Lane 3). Cell lysates were incubated with FLAG-trap beads and subsequently washed extensively. Samples before (Input) and after (IP) immunoprecipitation were analyzed using anti-GFP or -FLAG antibody. (B) BiFC assays for the interaction between V1 and V2 proteins in N. benthamiana cells. The V1-V2 interaction leads to a reconstituted fluorescence signal. DAPI stains DNA in the nucleus. Bars: 50 μm.
