RTY — Brassica oleracea

Summary

BoRTY, encoded by gene BOLC102_C07P000360.1 on cabbage chromosome 7, is a pyridoxal phosphate-dependent aminotransferase with S-alkylthiohydroximate lyase, carbon-sulfur lyase, and multiple transaminase activities, including nicotianamine aminotransferase and 1-aminocyclopropane-1-carboxylate synthase activity. The gene is associated with auxin biosynthesis and accumulation, glucosinolate biosynthesis and breakdown, ethylene biosynthesis, and secondary metabolite biosynthesis. It is linked to shoot growth, root development including adventitious and lateral root formation, hypocotyl elongation, apical hook formation, fruit ripening, and defence response to fungi, including powdery mildew resistance. The encoded protein localises to the mitochondria and cytosol. Studies of related genes in other species link the family to drought tolerance, water use efficiency, seed dormancy, and wheat powdery mildew disease response.
