ATR1 — Brassica oleracea

Summary

BoATR1 (also known as BoMYB34) on chromosome 7 of cabbage encodes a Myb-domain transcription factor with DNA-binding and transcription factor activity, localised to the nucleus. It is associated with the regulation of defense response to insect, glucosinolate anabolism, indole glucosinolate anabolism, tryptophan formation, and positive regulation of flavonoid anabolism. The gene is linked to cellular response to sulfur starvation, response to desiccation, hyperosmotic salinity response, and extracellular ATP signaling, as well as stomatal complex development and regulation of secondary cell wall biogenesis. Associations with agronomic traits include aphid response trait, insect damage response trait, drought tolerance, disease tolerance, seed protein content, sulfur content, lignin biosynthesis trait, flowering time trait, shoot elongation under submergence, root mass density, and lateral root length. Studies of related genes in other species link the family to auxin content, insect herbivory resistance, and resistance to fungal pathogens.
