ATR1 — Brassica oleracea

Summary

BoATR1 (also known as BoMYB34) on cabbage chromosome 9 encodes a Myb-domain transcription factor that localises to the nucleus and binds DNA, chromatin, calcium ions, kinases and bHLH transcription factors. The gene is associated with the regulation of defence response to insect, glucosinolate anabolism, indole glucosinolate anabolism, tryptophan formation, positive regulation of flavonoid anabolism, regulation of lignin anabolism, regulation of secondary cell wall biogenesis, stomatal complex development, hyperosmotic salinity response, response to desiccation, and cellular response to sulfur starvation. BoATR1 has been linked to numerous agronomic traits including aphid response trait, insect damage response trait, disease tolerance, drought tolerance, seed protein content, sulfur content, shoot elongation under submergence, phosphorus response, branch angle, root mass density, lateral root length, flowering time trait, leaf senescence trait, and stomatal opening. Studies of related genes in other species connect the family to indolic glucosinolate accumulation, camalexin biosynthesis, insect herbivory resistance, and tryptophan metabolism.
