title: The mechanism of leaf morphogenesis.
abstract: Whether cell division is a driving force in plant morphogenesis has long been debated. In this review, the evidence for the existence of cell division-dependent and cell division-independent mechanisms of plant morphogenesis is discussed. The potential mechanisms themselves are then analysed, as is our understanding of the regulation of these mechanisms and how they are integrated into development, with particular emphasis on data arising from the investigation of leaf morphogenesis. The analysis indicates the existence of both cell division-dependent and cell division-independent mechanisms in leaf morphogenesis and highlights the importance of future investigations to unravel the co-ordination of these mechanisms.
