Regulation of plant development: We use techniques of genetics, molecular biology, microscopy, physiology, and biochemistry to study how endogenous developmental programs and exogenous signals cooperate to determine plant form. The model plant Arabidopsis thaliana has numerous technical advantages that allow rapid experimental progress. We focus on how the plant hormone auxin acts in several different developmental contexts. Among questions of current interest are i) how auxin regulates patterning in embryos and ovules, ii) how light modifies auxin response, iii) how feedback loops affect kinetics or patterning of auxin response, iv) how flower opening and pollination are regulated, and v) whether natural variation in flower development affects rates of self-pollination vs. outcrossing.,Regulation of plant development: We use techniques of genetics, molecular biology, microscopy, physiology, and biochemistry to study how endogenous developmental programs and exogenous signals cooperate to determine plant form.
