RTY — Brassica oleracea var. botrytis

Summary

BoRTY, encoded by gene BOLND125_C07P009060.1 on cauliflower chromosome 7, is a pyridoxal phosphate-dependent aminotransferase with S-alkylthiohydroximate lyase, carbon-sulfur lyase, and multiple transaminase activities, including L-tyrosine-2-oxoglutarate transaminase and nicotianamine aminotransferase. It is associated with glucosinolate and IAA biosynthesis, ethylene production, stomatal closure, fruit ripening, defence response to fungi, and regulation of growth by external signals. The protein localises to mitochondria and cytosol. BoRTY is linked to water use efficiency, drought tolerance, auxin accumulation and overproduction, root and shoot development, hypocotyl elongation, apical hook formation, and powdery mildew resistance. Studies of related genes in other species connect the family to adventitious root number, shoot growth angle, seed dormancy, and auxin homeostasis.
