Plant growth is characterised both by continued growth and organogenesis throughout development, as well as by environmental influences on the rate and pattern of these processes. This necessitates a close relationship between cell cycle control, differentiation and development that can be readily observed and studied. The sequencing of the Arabidopsis genome has revealed the full complexity of cell cycle regulators in plants, creating a challenge to understand how these genes control plant growth and differentiation, and how they are integrated with intrinsic and external signals. Here, we review the control of the cell cycle and examine how it is integrated with proliferative activity within meristems, and during the differentiation processes leading to leaf and lateral root formation.

UI MeSH Term Description Entries
D002453 Cell Cycle The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE. Cell Division Cycle,Cell Cycles,Cell Division Cycles,Cycle, Cell,Cycle, Cell Division,Cycles, Cell,Cycles, Cell Division,Division Cycle, Cell,Division Cycles, Cell
D016213 Cyclins A large family of regulatory proteins that function as accessory subunits to a variety of CYCLIN-DEPENDENT KINASES. They generally function as ENZYME ACTIVATORS that drive the CELL CYCLE through transitions between phases. A subset of cyclins may also function as transcriptional regulators. Cyclin
D017360 Arabidopsis A plant genus of the family BRASSICACEAE that contains ARABIDOPSIS PROTEINS and MADS DOMAIN PROTEINS. The species A. thaliana is used for experiments in classical plant genetics as well as molecular genetic studies in plant physiology, biochemistry, and development.

D018517 Plant Roots The usually underground portions of a plant that serve as support, store food, and through which water and mineral nutrients enter the plant. (From American Heritage Dictionary, 1982; Concise Dictionary of Biology, 1990) Plant Bulbs,Plant Root,Bulb, Plant,Bulbs, Plant,Plant Bulb,Root, Plant,Roots, Plant
D018519 Meristem A group of plant cells that are capable of dividing infinitely and whose main function is the production of new growth at the growing tip of a root or stem. (From Concise Dictionary of Biology, 1990) Root Tip,Meristems,Root Tips,Tip, Root,Tips, Root
D029681 Arabidopsis Proteins Proteins that originate from plants species belonging to the genus ARABIDOPSIS. The most intensely studied species of Arabidopsis, Arabidopsis thaliana, is commonly used in laboratory experiments.
