MYB3 — Nicotiana attenuata

Summary

A4A49_28985 (MYB3/MYB4) in Nicotiana attenuata encodes a MYB transcription factor with DNA-binding, protein-dimerization, small GTPase-binding, and protein phosphatase activities. It is associated with specialized metabolite biosynthesis, herbivore resistance, and anti-herbivore defence. The gene is linked to trichome differentiation and spacing, root hair development, oviposition response, and iron starvation response. It has been connected to traits such as leaf trichome density, flavonoid and anthocyanin content, jasmonic acid and brassinosteroid levels, UV-B sensitivity, flowering time, seed development, and responses to abiotic stresses including salt, cold, and osmotic stress. The product localizes to the nucleus, cytoplasm, and root hair.
