ATY13 — Sorghum bicolor

Summary

SORBI_3007G138800 (SbATY13) on sorghum chromosome 7 encodes a MYB-family transcription factor with sequence-specific DNA-binding and transcription regulator activity. It is associated with brassinosteroid and gibberellin content, photoperiod-sensitive flowering time, shoot branching, stamen length, leaf shape, and root development traits. The gene is linked to cell wall polysaccharide, pigment, very-long-chain fatty acid, wax, and lignin anabolism, as well as abscisic acid biosynthesis regulation and signalling, UV protection, pollen exine formation, and negative regulation of water-deprivation response. Associations include drought response, freezing tolerance, seed dormancy and germination, stomatal regulation, cuticular wax accumulation, salt tolerance, and plant defence responses. Studies of related genes in other species connect the family to drought tolerance, wax biosynthesis, chilling tolerance, and pathogen defence.
