GSL-OH — Brassica oleracea var. botrytis

Summary

BoGSL-OH (GSL-OH) on cauliflower chromosome 3 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 glucosinolate biosynthesis and regulation, coumarin and flavonoid anabolism, ethylene anabolism, alkaloid metabolism, fruit ripening, defense responses to oomycetes and fungal molecules, and response to iron(III). Its product localizes to the cytosol, nucleus, vacuole, plasmodesma, and stress granule. The gene is linked to insect resistance and 2-hydroxybut-3-enyl glucosinolate accumulation. Studies of related genes in other species connect the family to drought tolerance, cytokinin content, and salt tolerance.
