TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C08P026550.1) on cabbage chromosome 8 encodes a protein with beta-glucosidase, sinigrase, beta-apiosyl-beta-glucosidase, and beta-galactosidase activities, belonging to the glycosyl hydrolase 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, abscisic acid response, and regulation of stomatal movement. It is linked to flowering time, chlorophyll content, disease tolerance, insect herbivory resistance, pathogen resistance, and programmed cell death resistance. The product localizes to the vacuole, apoplast, plant-type cell wall, plasmodesmata, and secretory vesicles. Related genes in other species connect the family to myrosinase activity, reduced herbivore resistance, and cell wall modification.
