TAIREncodes MYR1 (MYR1).
UniProtTranscription factor that may act on the GAL1 promoter (PubMed:12008900). Acts redundantly with MYR2 as a repressor of flowering and organ elongation under decreased light intensity (PubMed:21255164). Represses gibberellic acid (GA)-dependent responses and affects levels of bioactive GA (PubMed:21255164). {ECO:0000269|PubMed:21255164, ECO:0000305|PubMed:12008900}.
