Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT1G32640 AtMYC2/JIN1 abscisic acid The Ds element was inserted in the open reading frame of AtMYC2, between amino acids 107 and 108. Encodes a MYC-related transcriptional activator with a typical DNA binding domain of a basic helix-loop-helix leucine zipper motif. Binds to an extended G-Box promoter motif. Its transcription is induced by dehydration stress and ABA treatment. Negative regulator of blue light杕ediated photomorphogenic growth and blue and far-red-light杛egulated gene expression. Positive regulator of lateral root formation. Regulates diverse JA-dependent functions. Negatively regulates Trp metabolism and biosynthesis of Trp-derived secondary metabolites. Positively regulates flavonoid biosynthesis, resistance to insects, and response to oxidative stress. Regulates other transcription factors, and negatively regulates its own expression.
