Abstract:

In the past decade, significant knowledge has accumulated regarding gibberellin (GA) signal transduction in rice as a result of studies using multiple approaches, particularly molecular genetics. The present review highlights the recent developments in the identification of GA signaling pathway components, the discovery of GA-induced destruction of GA signaling repressor (DELLA protein), and the possible mechanism underlying the regulation of GA-responsive gene expression in rice.

Key words: gene expression, gibberellin, protein degradation, rice, signal transduction.
