It has been hypothesized that myosin and other cell components are located on vesicles to organize the actin network during polarized growth. Using confocal microscopy and fluctuation cross correlation analyses, I investigated the association of class II formins with vesicles and F-actin in Physcomitrella patens caulonemal cells. I found that formin2A co-localized with both VAMP, a vesicle marker, and Lifeact, an F-actin probe. Furthermore, formin2A fluctuated in phase with VAMP, but preceded Lifeact, in agreement with the hypothesis.
