Living cells constantly adjust the composition and size of their membrane systems to accommodate the demands for the housekeeping activities, to expand and reduce cell size, and to commit the cell for division. Although it is well known that vesicles are the vehicles to deliver and retrieve lipids and proteins to and from the membranes, the mechanisms allowing vesicles to pinch off from membranes...
Plant cells undergoing cytokinesis (cytoplasmic division) form a cell plate in the center of the phragmoplast. The phragmoplast consists of both cytoskeletal and membranous elements. The cytoskeletal elements are required for the delivery of vesicles to the equatorial region of the cell and provide guidance to the cell plate. Vesicles, originating from the Golgi apparatus, travel along microtubules...
