The study of cell cycle control in plants is expected to contribute to the understanding of plants' unique developmental features. The principal regulators of the eukaryotic cell cycle, namely, cyclin-dependent kinases (CDKs) and cyclins, are also conserved in plants. This review is concerned with our present knowledge on cell cycle regulation in Arabidopsis thaliana, which is widely accepted as a model plant for the study of a broad range of biological questions. Up to the present, 2 CDKs and 11 cyclins have been identified in Arabidopsis. While the expression of one of these CDKs has been found to be positively correlated with the competence of cells to divide, cyc1A1 expression of the cyclin has been almost exclusively confined to dividing cells. Although much remains to be studied concerning upstream regulators of these genes, the successful introduction of mutant CDKs into plants demonstrates the potential of using such an approach to intentionally modulate the plant cell cycle and development.
