Functional Description ? help Back to Top
Source	Description
UniProt	Acts as negative regulator of seedling photomorphogenesis (PubMed:18540109). Acts as a negative regulator of blue light-mediated inhibition of hypocotyl elongation through increase of bioactive gibberellin levels (PubMed:20872270). Acts as a repressor of thermotolerance by modulating expression of a set of heat shock-responsive genes (PubMed:23238922). {ECO:0000269\|PubMed:18540109, ECO:0000269\|PubMed:20872270, ECO:0000269\|PubMed:23238922}.
