A fusion genetic strategy was used to identify gibberellin (GA) signaling mutants in transgenic Arabidopsis expressing the beta-glucuronidase (GUS) and firefly luciferase (LUC) reporter genes under control of the GA-responsive GASA1 promoter. Initial analyses determined the spatial and temporal patterns of reporter expression, and showed that reporter induction by GA was antagonized by ABA. gamma-Irradiated M2 progeny with altered reporter activities were identified by LUC bioimaging followed… CONTINUE READING
