ATY13 — Sorghum bicolor

Summary

SORBI_3005G020200 (SbATY13) on sorghum chromosome 5 encodes a MYB transcription factor with sequence-specific DNA binding, transcription regulator activity, and additional molecular functions including steroid, chromatin, and SNARE binding. It is associated with pigment and phlobaphene biosynthetic processes, cell wall polysaccharide and very-long-chain fatty acid anabolism, regulation of abscisic acid and lignin biosynthesis, and responses to brassinosteroid, UV, water deprivation, and insect defense. The gene is linked to traits including brassinosteroid and gibberellin content, photoperiod-sensitive flowering, temperature stress response, stomatal opening, root development, and shoot branching. Related genes in other species are associated with drought tolerance, cuticular wax accumulation, seed oil content, and defense responses, though these functions are not established for SbATY13 itself.
