Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT3G26790 FUS3 abscisic acid A replaced G at the 5`end of the third intron. Transcriotional factor with high similarity to the B3 region of the VP1/ABI3-like proteins. Full length FUS3 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 FUS3 requires the B3 DNA-binding domain and an activation domain.
AT1G28300 LEC2 abscisic acid two deletions,3048bp and 895bp upstream and downstream of the translational start codon, non-linked toT-DNA insertion Transcription factor that contains a B3 domain, a DNA-binding motif unique to plants and characteristic of several transcription factors. Plays critical roles both early and late during embryo development.
