| Research Abstract |
In this study, we analized a new gibberellin (GA) signal transduction pathway . We found that the concentrations of intracellular Ca^2+are increased through a new signaling pathway in response to Gas. Furthermore, we found and analyzed a transcription factor GAF1 that specifically binds to DELLA proteins, negative regulators of GA signaling. Our biochemical studies suggest that DELLA proteins promote target genes of GAF1 as coactivators of GAF1.
