Cellular Behavior of Nonfunctional ACR4 Variants.
Visualization of GFP ([A] and [D]), FM4-64 ([B] and [E]), and merged images ([C] and [F]) of root cells from plants carrying the ΔREPEAT:GFP construct. (A) to (C) show cells from the elongation zone, and (D) and (E) show BFA-treated meristematic cells. Little or no colocalization of GFP and FM4-64 is observed in these plants. BFA bodies are indicated with arrows. Bars = 5 μM.
