Our main interest is in understanding how extracellular signals are perceived by plant cells to produce cellular responses. In particular, we wish to define the signal transduction pathway for the plant steroid hormone brassinosteroids. Brassinosterods are required for cell expansion, and mutations in genes required for brassinosteroid biosynthesis or signaling have a characteristic dwarf phenotype. To accomplish this we are using the genetic tools available in Arabidopsis to identify additional components of the signaling pathway that initiates with perception at the plasma membrane and ends with changes in transcription and reorganization of the cytoskeleton.
