Research Interests
How does organ shape evolve during growth? Molecular basis of early events in plant development such as patterning the apical meristems and specifying organ identity have been studied in detail. Yet how this regional information is translated into the mature organ of a particular shape and size is poorly understood. For example, it is not clear how various cell types differentiate in a coordinated manner to shape up the final leaf structure. Our laboratory is interested in studying the genetic basis of organ growth and development in plants. We are using Arabidopsis thaliana and other plant species to the function of the genes that regulate organ shape and size.
