ABSTRACT

Cell number and expansion are two key parameters controlling the size of tissues, organs, and the whole plant. The cell division cycle is directly responsible for cell production (i.e., cell number), but it also inuences plant shape, architecture, and morphogenesis through spatial regulation of cell wall deposition at cytokinesis, and at least in some notable cases of agricultural relevance also through cell expansion. Thus, it is intuitive that detailed understanding of the cell cycle, coupled with the ability to manipulate it, has the potential to signicantly contribute to maximizing crop
