Characean internodal cells readily form wound walls upon local membrane damage. In the
present study we documented the dynamics of vesicles involved in wound wall secretion
and compared them with actin organization in equivalent cells using immunofluorescence.
Single exocytotic events (spreading of vesicle contents) could be visualized using image
enhancement by video microscopy. In control unwounded cells vesicles moved
unidirectionally along parallel actin bundles and rarely contacted the plasma membrane …
