TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C02P065410.1_BOLC102_V1) on cabbage chromosome 2 encodes a protein with beta-glucosidase, sinigrase, beta-apiosyl-beta-glucosidase, beta-D-fucosidase 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. BoTGG1 is associated with flowering time, stomatal closure, cytosolic calcium elevation, guard cell structure, abscisic acid response, pathogen resistance, programmed cell death resistance, chlorophyll content, disease tolerance, and jasmonic acid signaling. The protein localises to the vacuole, plant-type cell wall, apoplast, plasmodesma, plastid, thylakoid, secretory vesicle and cytosolic ribosome. Studies of related genes in other species link the family to myrosinase activity, insect resistance and cell wall modification.
