Abstract
The gibberellin (GA) signaling pathway, like auxin and jasmonate signaling, uses the ubiquitin–proteasome pathway to control expression through protein degradation. A conserved F-box protein of an SCF E3 ubiquitin ligase is a positive regulator of GA signaling in
Arabidopsis and rice. GA apparently stimulates stem elongation by causing this SCF complex to regulate negatively a family of negative regulators of GA response (the DELLA family of putative transcription factors). The DELLA family members AtRGA or (Repressor of
ga1-3) and OsSLR1 (SLENDER RICE1) proteins both appear to be subject to GA-induced proteolysis. The need to have the F-box genes
AtSLY1 and
OsGID2 for this proteolysis suggests that GA causes proteolysis of AtRGA/OsSLR1 via the SCF
AtSLY1/OsGID2 ubiquitin ligase.
