TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C09P012580.1) on cabbage chromosome 9 encodes a protein with beta-glucosidase, sinigrase, beta-apiosyl-beta-glucosidase, and beta-galactosidase activities, belonging to the glycosyl hydrolase 1 family. In cabbage, BoTGG1 is associated with flowering time, defense responses to insects and viruses, glucosinolate anabolism, jasmonic acid and abscisic acid signaling, regulation of stomatal movement, and plasmodesma-mediated transport. It is linked to glucosinolate content, insect herbivory resistance, pathogen resistance, stomatal closure, cytosolic calcium elevation, chlorophyll content, and disease tolerance. The protein localizes to the vacuole, apoplast, plant-type cell wall, plasmodesmata, secretory vesicles, and plastids. Studies of related genes in other species connect the family to myrosinase activity, insect resistance, and cell wall modification.
