TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C02P066000.1_BOLC102_V1) on cabbage chromosome 2 encodes a protein with beta-glucosidase, sinigrase, and multiple glycoside hydrolase activities, belonging to the Glyco_hydro_1 family. The gene is associated with glucosinolate metabolism, including breakdown, hydrolysis, and accumulation, as well as defense responses to insects and viruses, jasmonic acid signaling, and abscisic acid response. It has been linked to flowering time, stomatal closure, guard cell structure, cytosolic calcium elevation, and electrical signaling. Associations also include chlorophyll content, disease tolerance, pathogen resistance, and programmed cell death resistance. The protein localizes to the vacuole, apoplast, plant-type cell wall, plasmodesmata, and secretory vesicles. Studies of related genes in other species link the family to myrosinase activity, herbivore resistance, and cell wall modification.
