Leaf initiation: the integration of growth and cell division.
The shoot apical meristem of higher plants is characterized by a conserved pattern of cell division, the functional significance of which is unclear. Although a causal role for cell division frequency and orientation in morphogenesis has been suggested, supporting data are limited. An alternative interpretation laying stress on the control of growth vector and its integration with networks of transcription factors and hormonal signals is discussed in this review.
