The molecular mechanisms that control cell cycle progression are highly conserved in eukaryotes. In addition to the basic protein machinery involved in cell cycle regulation, higher plants have also evolved unique molecular mechanisms that allow integration of environmental, physiological, and developmental signals into networks to control proper cell division and expansion. Rapid progress in plant cell division control has been achieved over the past decade with the aid of experimental observations of plants. This volume focuses on the molecular basis of cell division and cytokinesis in plants. It is an essential reference book for instructors and scientists working in molecular, cell, and developmental biology of plants. The editors of this book are veterans in plant molecular biology and highly respected worldwide.
