TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C08P015210.1) on cabbage chromosome 8 encodes a protein with sinigrase, beta-glucosidase, and multiple glycoside hydrolase activities, belonging to the Glyco_hydro_1 family. The gene is associated with glucosinolate metabolism, including glucosinolate breakdown, hydrolysis, and accumulation, as well as defense responses to insects and viruses, jasmonic acid signaling, abscisic acid response, and regulation of stomatal movement. It is linked to flowering time, chlorophyll content, disease tolerance, and insect herbivory resistance. The product localizes to the vacuole, apoplast, plasmodesma, and secretory vesicles. Studies of related genes in other species connect the family to myrosinase activity, insect resistance, and cell wall modification.
