TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C09P012600.1) on cabbage chromosome 9 encodes a protein belonging to the glycosyl hydrolase family 1, with beta-glucosidase, sinigrase, beta-apiosyl-beta-glucosidase, b-L-arabinosidase, beta-gentiobiose beta-glucosidase, glucan exo-1,3-beta-glucosidase, beta-D-fucosidase, beta-galactosidase, and metal binding activities. The gene is associated with glucosinolate metabolism, including breakdown, hydrolysis, and accumulation, as well as defense responses to insects and viruses, jasmonic acid and abscisic acid signaling, regulation of stomatal movement, and flowering time. It has been connected to glucosinolate content, insect herbivory resistance, pathogen resistance, chlorophyll content, disease tolerance, and guard cell structure. The product localizes to the vacuole, apoplast, plasmodesmata, and plant-type cell wall. Studies of related genes in other species link the family to myrosinase activity, insect resistance, and cell wall modification.
