TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C09P012590.1) on cabbage chromosome 9 encodes a protein with beta-glucosidase, sinigrase, beta-apiosyl-beta-glucosidase, and beta-galactosidase activities, belonging to the glycosyl hydrolase family 1. The gene is associated with glucosinolate metabolism, including breakdown, hydrolysis, and accumulation, and with defense responses to insects and viruses. It has been linked to flowering time, stomatal closure, cytosolic calcium elevation, abscisic acid response, and jasmonic acid signaling. Associations also include chlorophyll content, disease tolerance, and antiviral defense. The protein localizes to the vacuole, apoplast, plasmodesma, and secretory vesicle. Related genes in other species are linked to myrosinase activity, insect resistance, and cell wall modification.
