TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C08P015080.1) on cabbage chromosome 8 encodes a protein with beta-glucosidase activity, sinigrase activity, and other glycoside hydrolase activities, belonging to the glycosyl hydrolase 1 family. The gene is associated with glucosinolate metabolism, including glucosinolate breakdown, hydrolysis, and accumulation, as well as defense responses to insects and viruses. BoTGG1 is associated with flowering time, stomatal closure, cytosolic calcium elevation, and abscisic acid response. It is linked to chlorophyll content and disease tolerance. The protein localizes to the vacuole, plant-type cell wall, apoplast, plasmodesma, and secretory vesicle. Studies of related genes in other species link the family to myrosinase activity, insect resistance, and cell wall modification.
