Plant Cytoskeleton: Reinforcing Lines of Division in Plant Cells

Cytokinesis in plants has unique features concerned with defining and maintaining the line of cell division. Recent studies have identified key cytoskeletal components and events that help to ensure the fidelity of cytokinesis in higher plants.

Tangled localization at the cortical division site of plant cells occurs by several mechanisms.

TANGLED (TAN) is the founding member of a family of plant-specific proteins required for correct orientation of the division plane. Arabidopsis thaliana TAN is localized before prophase until the end of cytokinesis at the cortical division site (CDS), where it appears to help guide the cytokinetic apparatus towards the cortex. We show that TAN is actively recruited to the CDS by distinct mechan...

The Role of Endocytosis in the Creation of the Cortical Division Zone in Plants

Control of the pattern of cell division is essential for the proper development of multicellular organisms. In animal cells, cytokinesis is mediated by a contractile ring in which the cleavage force is produced by an acto-myosin system. Furthermore, the future site of cell division in animal cells (the site where contraction starts in the cell cortex) is determined by the position of the aster ...

Determination of symmetric and asymmetric division planes in plant cells.

The cellular organization of plant tissues is determined by patterns of cell division and growth coupled with cellular differentiation. Cells proliferate mainly via symmetric division, whereas asymmetric divisions are associated with initiation of new developmental patterns and cell types. Division planes in both symmetrically and asymmetrically dividing cells are established through the action...
