DELLA-mediated PIF degradation contributes to coordination of light and gibberellin signalling in Arabidopsis
Abstract
Gibberellins (GA) negatively regulate light-mediated suppression of hypocotyl elongation in plants. Here, Li et al. show that GA-mediated destabilization of DELLA proteins promotes accumulation of the light-regulated PIF transcription factors thus contributing to the crosstalk between light and GA signalling.
