Leaf Identities

Project overview:

MicroRNAs control developmental transitions in many organisms.  In maize, the transition from juvenile to adult leaf identity is controlled by interactions between miR172 and Gl15, miR156 and SPL genes.  Maize seedling leaves differ from adult leaves in their production of waxes, leaf hairs and biochemical composition of cell walls, which contribute to stress tolerance and disease pathogen resistance (see figure below).  Using maize as an experimental system, we are investigating how variation in microRNAs has influenced the regulation of developmental timing in natural as well as mapping populations.
