Gibberellin signalling pathway

Curr Opin Plant Biol. 2003 Oct;6(5):489-93. doi: 10.1016/s1369-5266(03)00079-7.


Recent molecular biological and genetical studies have identified several positive and negative regulators of gibberellin (GA) signalling pathways in higher plants. The DELLA protein functions as a negative regulator of GA signalling; its degradation through the ubiquitin/proteasome pathway is a key event in the regulation of GA-stimulated processes.
