    Research Fields：

       The research in our lab is mainly focused on the molecular genetics of plant organogenesis and the plant hormone signaling during morphogenesis.

    Molecular control of organ development
       In plants, the development of an organ involves cell proliferation, differentiation and growth, which are tightly coordinated and controlled during organogenesis. We are trying to dissect the molecular control of organ development, including how the size and number of organs are determined and what signals are involved in.

    Plant hormone signals during growth and development
       Plant hormones play a critical role in the growth and development. We are also interested in plant hormone signal molecules, especially auxin and brassinosteroid signals important for plant morphogenesis. We are going to identify these molecules and define their regulations in developmental processes.

    Molecular basis of the roles of auxin in plant cell culture
       Auxin is essential for callus formation and plant regeneration in tissue culture system. We are very much interested in the signals involved in these processes. We will identify and characterize such genes and signal components.
