FM4-64 Labeling.
Confocal images of cowpea protoplast expressing BRI1-YFP (A) and AtSERK3-YFP ([D], yellow) were labeled with FM4-64 (red) and viewed after 3 h for BRI1-YFP (B) and for AtSERK3-YFP (E). The superimposed images of (A) and (B) resulted in (C), and the superimposed images of (D) and (E) resulted in (F). Arrowheads point to the overlapping yellow and red dots representing endosomes in (C) and (F). Bars = 10 μM.
