Can a single layer of cells control a leaf's size?

Little is known about the developmental control of leaf size and shape, and understanding the mechanisms behind this is a major issue in plant biology. New research concludes that communication between adjacent cell layers plays an important role in determining leaf size. Cells in one tissue layer can control the rate of division of cells in another tissue layer, which in turn influences overall leaf size.
