When plant cells decide to divide

Progression through the cell cycle is central to cell proliferation and fundamental to the growth and development of all multicellular organisms, including higher plants. The periodic activation of complexes containing cyclins and cyclin-dependent kinases mediates the temporal regulation of the cell-cycle transitions. Here, we highlight recent advances in the molecular controls of the cell cycle in plant cells, with special emphasis on how hormonal signals can modulate the regulation of cyclin-dependent kinases
