The Barton lab studies how plants make new leaves and stems from clusters of undifferentiated cells located at the tips of branches. These clusters of cells are called apical meristems and contain within them a small number of self renewing stem cells. Within the meristem, the decision as to what type of cell a cell ultimately becomes is controlled by a network of transcription factors. Recently, our studies have identified points where environmental signals interact with this intrinsic genetic program to modify growth. We hypothesize this interaction serves to coordinate the production of leaves and stems with the availability of water and nutrients. The understanding of plant growth and development gained from these studies establishes a foundation that can be used to breed resilient plants, thereby increasing food security in the face of a changing environment.
