TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C09P012610.1) on cabbage chromosome 9 encodes a protein belonging to the glycosyl hydrolase 1 family, with beta-glucosidase, sinigrase, and beta-apiosyl-beta-glucosidase activities. In cabbage, BoTGG1 is associated with flowering time, defense responses to insects and viruses, glucosinolate anabolism, jasmonic acid signaling, abscisic acid response, regulation of stomatal movement, and plasmodesma-mediated cell-to-cell transport. The protein localizes to the vacuole, apoplast, plasmodesmata, and secretory vesicles. BoTGG1 is linked to glucosinolate content, insect herbivory resistance, stomatal closure, cytosolic calcium elevation, pathogen resistance, and disease tolerance. Studies of related genes in other species connect the family to myrosinase activity, insect resistance, and cell wall modification.
