Photoperception and Signal Transduction Mechanisms in plants; Plant Hormone Action Mechanisms; Structural and Functional Genomics in Plants
Our group has contributed extensively to the area of light perception and signal transduction mechanisms in plants. Some of the initial works on Arabidopsis mutants lead to the identification of the blue light receptor, phototropin1, which in fact remained elusive for over a century. During a screen for phototropism mutants, we also identified constitutively photomorphogenic mutants that display de-repression of gene expression in dark and flower precociously.
