AS1 — Arabidopsis thaliana

Summary

AT2G37630, also known as AS1, ASYMMETRIC LEAVES 1, or MYB DOMAIN PROTEIN 91, encodes a protein with a MYB domain and transcription regulator activity, and is annotated with DNA-binding transcription activator activity. In Arabidopsis thaliana, AS1 is associated with leaf, gynoecium, and fruit patterning, as well as leaf morphogenesis. The gene is linked to raffinose breakdown and raffinose content, and has been connected to traits including leaf flexibility, leaf margin serration, leaf area index, harvest index, inflorescence height, photoperiod sensitivity, and stem length. AS1 is also associated with flower abscission zone morphology, carpel number, root branching, and brassinosteroid content. Studies of related genes in other species link the AS1 family to root weight, leaf thickness, and leaf color.
