RTY — Brassica oleracea var. botrytis

Summary

BoRTY, located on chromosome 7 of cauliflower (Brassica oleracea var. botrytis), encodes a pyridoxal phosphate-dependent aminotransferase with S-alkylthiohydroximate lyase, carbon-sulfur lyase, nicotianamine aminotransferase, and L-tyrosine-2-oxoglutarate transaminase activities. This gene is associated with IAA biosynthetic process, tyrosine breakdown, glucosinolate anabolism, adventitious root development, stomatal closure, and defence response to fungi. It has been linked to water use efficiency and drought tolerance, as well as phenotypes including auxin accumulation, ethylene insensitivity, apical hook formation, lateral root development, hypocotyl elongation, and powdery mildew resistance. The product localises to mitochondria, cytosol, and cytoplasm. Related genes in other species are linked to auxin overproduction, glucosinolate biosynthesis, and root development.
