ATY13 — Zea mays

Summary

ZmATY13 (also known as ZmMYB60, ZmMYB31, and ZmMYB96) on maize chromosome 1 encodes a transcription factor with sequence-specific DNA-binding and transcription regulator activity, and is associated with protein kinase, steroid-binding, and SNARE-binding functions. The gene is linked to anthocyanin breakdown and metabolism, pigment accumulation, pigmentation, and UV protection, as well as to the regulation of abscisic acid and very-long-chain fatty acid anabolism, sphingolipid metabolism, and the shikimate pathway. Associations with agronomic traits include grain color, ear length, lignin content, brittle culm, seed shattering, shoot branching, leaf morphology, stem elongation, and responses to drought, temperature stress, and insects. Studies of related genes in other species link the family to drought tolerance, cuticular wax accumulation, stomatal regulation, seed oil accumulation, and defense responses.
