TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C09P012570.1) on cabbage chromosome 9 encodes a protein with beta-apiosyl-beta-glucosidase, sinigrase, b-L-arabinosidase, beta-gentiobiose beta-glucosidase, glucan exo-1,3-beta-glucosidase, beta-D-fucosidase, beta-glucosidase, and beta-galactosidase activities, and belongs 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 and abscisic acid signaling, and regulation of stomatal movement. It has been linked to flowering time, chlorophyll content, disease tolerance, and traits such as insect herbivory resistance, pathogen resistance, and callose deposition. The product localizes to the vacuole, plant-type cell wall, apoplast, plasmodesmata, and secretory vesicles, and is associated with cell-to-cell transport and systemic acquired resistance. Related genes in other species link the family to myrosinase activity, herbivore resistance, and cell wall modification.
