ATY13 — Sorghum bicolor

Summary

SORBI_3007G138900 (SbATY13) on sorghum chromosome 7 encodes a Myb-family transcription regulator with sequence-specific DNA-binding, transcription regulator activity, and steroid-binding activities. It is associated with brassinosteroid content, gibberellin biosynthesis, photoperiod-sensitive flowering time, and temperature stress response traits. The gene is linked to cell wall polysaccharide anabolism, pigment anabolism, regulation of abscisic acid anabolism, very-long-chain fatty acid anabolism, upregulation of wax anabolism, and regulation of lignin anabolism. It has been connected to drought response, freezing tolerance, seed dormancy and germination, stomatal regulation, cuticular wax accumulation, and root development traits. Additional associations include shoot axis branching, leaf morphology, stamen length, pollen fertility restoration, and responses to auxin, ethylene, and nitrate uptake. Studies of related genes in other species link the family to drought tolerance, wax biosynthesis, anthocyanin accumulation, and defense responses.
