Gibberellins (GA) has diverse effects on plant growth and development including seed germination, leaf expansion, hypocotyls and stem elongation, and flower initiation etc. We are interested in the molecular mechanism controlling plant growth and flowering underlying GA signaling in plants. We use the Arabidopsis and rice as model plants; carry our screens for new mutants based on the repressing/suppressing for GA responses, which will identify genes encoding proteins required for GA signaling. We are using genetic, molecular and biochemical approaches to investigate the functions of their encoded products, to gain an understanding of the mechanism of GA-mediated growth in Arabidopsis growth and GA-mediated induction of α-amylase activity in rice.
