Abstract:
Cytokinesis in plant cells in accomplished when a membranous cell plate is guided to a pre-established division site. The orientation of the new wall establishes the starting position of a cell in a growing tissue, but the impact of this position on future development varies. Recently, proteins have been identified that participate in forming, stabilizing and guiding the cell plate to the correct division site. Mutations that affect cytokinesis with varying impacts on plant development are providing information about the mechanics of cytokinesis and also about how the division site is selected.
