For2A localizes to sites of dynamic membrane trafficking. (A) For2A-GFP localizes to the tip of the cell and to the phragmoplast. The PTEN domain of For2A alone, fused to GFP also localizes to the tip and the phragmoplast. See also Videos 1 and 2. (B) FM4-64–labeled membranes and For2A colocalize in the phragmoplast, but not the cell plate. Shown is the medial plane of a cell with an almost completed cell division. (C) For2A colocalizes with FM4-64–labeled membranes near the tip. See also Video 3 and Fig. S1. Bars, 5 µm.
