Early events in leaf development.

Morphological studies of early events in leaf development have been hindered by the lack of stereotypic patterns of cell division and markers for cell identity. However, molecular genetic analysis, particularly in maize, has begun to suggest the mechanisms which partition meristematic cells into a leaf primordium, define regional identities within the primordium and direct localised growth which leads to outgrowth and flattening of the leaf. Therefore, the leaf may provide a model for pattern formation applicable to other parts of the plant.
