The cytoplast concept in dividing plant cells: cytoplasmic domains and the evolution of spatially organized cell division

Pickett-Heaps, Jeremy; Gunning, Brian; Brown, Roslyn; Lemmon, Betty; Cleary, Ann L


The unique cytokinetic apparatus of higher plant cells comprises two cytoskeletal systems: A predictive preprophase band of microtubules (MTs), which defines the future division site, and the phragmoplast, which mediates crosswall formation after mitosis. We review features of plant cell division in an evolutionary context and from the viewpoint that the cell is a domain of cytoplasm (cytoplast) organized around the nucleus by a cytoskeleton consisting of a single 'tensegral' unit. The term...[Show more]
