In plants, hormones influence many diverse developmental processes ranging from seed germination to root, shoot and flower formation. I have chosen to study the plant hormones abscisic acid (ABA) and gibberellin (GA) in Arabidopsis thaliana as a model genetic system to understanding hormone signaling in plants. The program involves the identification of mutants with altered hormonal responses and the cloning of the subsequent genes that have been identified through these genetic screens.
