Figure 1. DRP1 and DRP2 in Cytokinesis and Cell Expansion.
(A) During cytokinesis Golgi- and early endosome-derived vesicles fuse and the division plane to form the cell plate. Consolidation and maturation of the cell plate requires DRP1 and DRP2 which may act through clathrin-dependent and independent processes. (B) In tip- growing or diffuse-growing plant cells, proteins, lipids and cell wall material are likely to be delivered via multiple exocytic pathways toward the PM. Membrane is recycled via DRP1, DRP2 and clathrin-dependent and possibly independent mechanisms from the PM and delivered to an endocytic compartment.
