摘要
The G1/S transition generally represents the principal point of commitment to cell division. Many of the components of the cell cycle core machinery regulating the G1/S transition in plants have been recently identified. Although plant regulators of the G1/S transition display structural and biochemical homologies with their animal counterparts, their functions in integrating environmental stimuli and the developmental program within cell cycle progression are often plant-specific. In this review, recent progress in understanding the role of plant G1/S transition regulators is presented. Emerging evidence concerning the mechanisms of G1/S control in response to factors triggering the cell cycle and the integration of these mechanisms with plant development is also discussed.
