title: Cytokinesis: lines of division taking shape.
abstract: Plant cytokinesis requires an orchestrated interplay of membrane and cytoskeleton dynamics, which results in the formation of the membrane that partitions the cytoplasm of the dividing cell. Until recently, phragmoplast-assisted cytokinesis of somatic cells was regarded as mechanistically different from 'non-conventional' modes of cytokinesis, such as endosperm cellularisation or male meiotic cytokinesis. However, features that are similar among these diverse modes of cytokinesis have now been revealed by electron tomography, suggesting common underlying mechanisms that are also supported by genetic and molecular studies. Further insight into the complex process of cytokinesis has been gained from the identification of new components and from the analysis of known components.
