Plant organ growth relies on the coordinated progression of cell proliferation, cell expansion and cell differentiation. Many regulators of organ growth promote or repress cell proliferation, thus a continuous supply of new cells through the progression of the mitotic cell cycle serves as a major driver of organ growth in higher plants. Unlike animal cells, plant cells also undergo extensive post-mitotic cell expansion, and increasing cell size by cell expansion is also vital for the full growth and development of plant organs. The transition from cell proliferation to cell expansion or cell differentiation is often accompanied by the transition from the mitotic cycle into the endocycle, and we are just beginning to understand how these closely linked cellular processes are regulated during post-embryonic plant development. In my talk I will describe our recent progress in elucidating how developmental and environmental signals program cell differentiation and how an increase in ploidy by the endocycle contributes to this control.
