The term ‘cytoskeleton’ might give a static impression given the inclusion of “skeleton,” a notion that is enforced by the fact that plant cells do not appear to be very active when compared to animal cells. However, the skeletal feature of the cytoskeleton function is only one component of its reality. When a plant cell forms and alters its shape, the cytoskeleton is intimately involved. Additionally, plant cells actively relocate some cellular components while keeping others in place. The cytoskeleton itself is a filamentous network of protein polymers comprised of three structural components: microtubules, actin filaments, and intermediate filaments. The former two play major roles in cellular rearrangements, and their fundamental structures are conserved in animals and plants. It is particularly interesting to take a look at the organization of plant mitotic structures from a phylogenetic viewpoint. The plant cytoskeleton also has unique functions and features, many of which are outlined in this chapter.
