ATY13 — Capsicum annuum

Summary

CaATY13 (T459_17708) on pepper chromosome 6 encodes a MYB-domain transcription regulator with sequence-specific DNA-binding, protein kinase, steroid-binding and SNARE-binding activities. It is associated with brassinosteroid response, anthocyanin, flavonoid, carotenoid and very-long-chain fatty acid biosynthesis, lignin regulation, UV protection, photomorphogenesis suppression, stomatal movement, pollen exine formation, tapetum differentiation, hypoxia response and green leaf volatile production. The gene is linked to pungency, brassinosteroid and gibberellin content, temperature stress responses, photoperiod-sensitive flowering, root phototropism, shoot branching, stamen length, nitrate uptake, leaf morphology, cell elongation, ethylene and auxin sensitivity, chloroplast development, and salt, heat, oxidative and submergence tolerance. Studies of related genes in other species connect the family to hypersensitive cell death, defense responses, cuticular wax accumulation, ABA signaling, seed dormancy and systemic acclimation.
