Shortening of Microtubule overlap regions defines membrane delivery sites during plant cytokinesis

de Keijzer, J.; Kieft, H.; Ketelaar, T.; Goshima, G.; Janson, M.E.


Plants and animals synthesize and move large amounts of membraneous material to construct a division plane for cell division. We define short stretches of antiparallel microtubule overlap as membrane accumulation sites in moss plants. Dimensions of the dividing cell plate are set by kinesin-4-mediated shortening of these overlaps.
