Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT3G24650 ABI3 abscisic acid at position 2143 in the cDNA insert; converting Asp-580 to Asn Homologous to the maize transcription factor Viviparous-1. Full length ABI3 protein binds to the highly conserved RY motif [DNA motif CATGCA(TG)], present in many seed-specific promoters, and the B3 domains of this transcription factor is necessary for the specific interaction with the RY element. Transcriptional activity of ABI3 requires the B3 DNA-binding domain and an activation domain
