TGG1 — Brassica oleracea

Summary

BoTGG1 (BOLC102_C02P065460.1) on cabbage chromosome 2 encodes a protein with sinigrase, beta-glucosidase, beta-galactosidase, and beta-D-fucosidase activities, belonging to the glycosyl hydrolase family 1. In cabbage, BoTGG1 is associated with flowering time. The gene has been linked to glucosinolate content, breakdown, hydrolysis, and accumulation, as well as insect defense, herbivory resistance, and pathogen resistance. It is associated with stomatal closure, guard cell structure, cytosolic calcium elevation, abscisic acid response, and programmed cell death resistance. Associations also include nitrate, phenolic, flavonoid, sucrose, proline, carotenoid, chlorophyll, and protein content, along with leaf number, root length, and root branching. The protein localizes to the vacuole, plant-type cell wall, apoplast, plastid, and plasmodesma. Studies of related genes in other species link the family to myrosinase activity, insect resistance, and cell wall modification.
