TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C02P065990.1) on cabbage chromosome 2 encodes a beta-glucosidase with multiple glycoside hydrolase family 1 domains and exhibits beta-apiosyl-beta-glucosidase, sinigrase, and beta-galactosidase activities. The gene is associated with glucosinolate metabolism, including anabolism, hydrolysis, and breakdown, as well as defense responses to insects and viruses, jasmonic acid and abscisic acid signaling, regulation of stomatal movement, and flowering time. It has been linked to chlorophyll content, disease tolerance, glucosinolate accumulation, insect herbivory resistance, pathogen resistance, and programmed cell death resistance. The encoded protein localizes to the vacuole, apoplast, plasmodesma, and plant-type cell wall. Studies of related genes in other species connect the family to myrosinase activity, reduced herbivore resistance, and cell wall modification.
