RTY — Brassica oleracea var. botrytis

Summary

BoRTY, located on cauliflower chromosome 7, 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, regulation of growth by external signal, adventitious root development, stomatal closure, and defence response to fungi. It localises to mitochondria, cytosol, and cytoplasm. BoRTY is linked to water use efficiency, drought tolerance, auxin accumulation, ethylene insensitivity, apical hook formation, hypocotyl elongation, lateral and adventitious root development, shoot growth, powdery mildew resistance, and glucosinolate biosynthesis. Related genes in other species are linked to auxin homeostasis, adventitious root formation, and short hypocotyls with chlorotic leaves.
