Abstract

In plant apical meristems, a central zone (CZ) of slowly dividing undifferentiated cells is surrounded by a peripheral zone where leaf primordia are initiated as groups of rapidly dividing cells. What distinguishes these zones at the molecular level and how is cell division related to organogenesis? We have characterised a family of cyclin D genes (CycD), which show differential meristem expression. CycD3a is primordia-specific and absent from the CZ. In contrast, knotted-like genes are expressed only in the CZ. Here we propose generating transgenic plants to address whether CycD3a expression drives organogenesis, and whether the localisation of its expression is important in defining meristem organisation and function.
