GSL-OH — Brassica oleracea var. botrytis

Summary

BoGSL-OH (GSL-OH) on chromosome 4 of cauliflower (Brassica oleracea var. botrytis) encodes a 2-oxoglutarate-dependent dioxygenase with 3-butenylglucosinolate 2-hydroxylase activity, also annotated for mugineic-acid 3-dioxygenase, ACC oxidase, and flavanone 3-dioxygenase activities. The gene is associated with the regulation of glucosinolate biosynthetic processes, glucosinolate anabolism, and the accumulation of 2-hydroxybut-3-enyl glucosinolate. It has been linked to defense responses to oomycetes, responses to fungal molecules, and insect resistance. Additional associations include coumarin, ethylene, flavonoid, and alkaloid anabolism, as well as fruit ripening and response to iron(III). The encoded protein is localized to the cytosol, nucleus, vacuole, plasmodesma, and stress granule. Studies of related genes in other species link the family to drought tolerance, cytokinin content, and salt tolerance.
