TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C06P041370.1) on cabbage chromosome 6 encodes a protein with sinigrase and beta-glucosidase activities, belonging to the glycosyl hydrolase family 1. The gene is associated with glucosinolate metabolism, including anabolism, hydrolysis, and breakdown, and has been linked to defense responses against insects and viruses, as well as jasmonic acid and abscisic acid signaling. BoTGG1 is linked to regulation of stomatal movement, flowering time, and chlorophyll content. The protein localizes to multiple cellular compartments including the vacuole, apoplast, plasmodesmata, and thylakoid. Studies of related genes in other species link the family to myrosinase activity, insect resistance, and cell wall modification. BoTGG1 is also associated with cytosolic calcium elevation, programmed cell death resistance, and disease resistance.
