TGG1 — Brassica napus

Summary

BnTGG1 (TGG1, BnBGLU38) on chromosome A02 of oilseed rape encodes a protein belonging to the glycosyl hydrolase family 1, with sinigrase, beta-glucosidase, beta-galactosidase, beta-D-fucosidase, glucan exo-1,3-beta-glucosidase, beta-gentiobiose beta-glucosidase, and beta-L-arabinosidase activities. The gene is associated with glucosinolate metabolism, breakdown, hydrolysis, and accumulation, as well as insect defense and herbivory resistance, pathogen resistance, and antiviral defense. It is linked to stomatal closure, cytosolic calcium elevation, abscisic acid response, and electrical signaling. Associations with plant height, shoot dry weight, root length, chlorophyll content, seed color, protein content, water use efficiency, and drought tolerance have been noted. The product localizes to the vacuole, plant-type cell wall, apoplast, plastid, plasmodesma, thylakoid, and secretory vesicle.
