GSL-OH — Brassica oleracea var. botrytis

Summary

BoGSL-OH (GSL-OH) on cauliflower chromosome 4 encodes a 2-oxoglutarate-dependent dioxygenase with 3-butenylglucosinolate 2-hydroxylase activity, also annotated for mugineic-acid 3-dioxygenase and ACC oxidase activities. The gene is associated with glucosinolate biosynthesis and its regulation, coumarin and flavonoid anabolism, ethylene anabolism, and defense responses to oomycetes and fungal molecules. It is linked to fruit ripening, alkaloid metabolism, and response to iron(III). The encoded protein localizes to the cytosol, nucleus, vacuole, plasmodesma, and stress granules. BoGSL-OH is associated with 2-hydroxybut-3-enyl glucosinolate accumulation and insect resistance. Studies of related genes in other species connect the family to drought tolerance, salt tolerance, cytokinin content, and insect damage response traits.
