The isolation of plant genes homologous to cdk and cyclin components from yeast and animals proves the existence of a basic cell cycle machinery in all eukaryotes. cdk and cyclin expression has been shown to be involved in the spatial and temporal control of cell division in a variety of developmental processes. In plants, cell division and development are closely interlinked processes that are regulated by phytohormones. cdks and cyclins were found to be under control of phytohormones underscoring their integral role in mediating different developmental pathways. Furthermore, studies on cdk and cyclin expression not only correlate with actual cell cycle activity but also with cell division competence providing a working model to understand regeneration capacity at the molecular level.
