title: [Modern conceptions about regulation of cell cycle in plants].
abstract: The most modern conceptions about regulation of cell cycle in plants are considered in the article. According to literary data, the main regulators of cell cycle are cyclines and cycline-dependent kinases. Four basic types of plant cyclines and series of cycline-depending kinases, that control different phases of cell cycle, are describe. As for the influence of physical factors (temperature, radiation, light, vibration, magnetic field and microgravity) on the parameters of cell cycle, then in most cases they arise similar reactions--increasing of the duration of cell cycle, that may be explained by the extension of presinthetic phase of the cycle. The study of influence of altered gravity on a cell proliferation is very important for understanding and further, investigations of the nature of peculiarities of a plant development and the study of molecular mechanisms of the cell cycle regulation under altered gravity.
