title: Leaf size control: complex coordination of cell division and expansion.
abstract: Size control of multicellular organisms poses a longstanding biological question that has always fascinated scientists. Currently the question is far from being resolved because of the complexity of and interconnection between cell division and cell expansion, two different events necessary to form a mature organ. Because of the importance of plants for food and renewable energy sources, dissecting the genetic networks underlying plant growth and organ size is becoming a high priority in plant science worldwide. Here, we review the current understanding of the cellular and molecular mechanisms that govern leaf organ size and discuss future prospects on research aiming at understanding organ size regulation.
