BG1 — Solanum lycopersicum

Summary

SlBG1 (SOLYC01G059965.1) encodes a plant glycosyl hydrolase family 17 protein with glucan exo-1,3-beta-glucosidase, lichenase, cellulase and glucan endo-1,3-beta-D-glucosidase activities. In tomato, the gene is associated with herbivore defense and sugar/organic acid ratio. It is associated with carotenoid metabolism, camalexin anabolism, induced systemic resistance, abscission, nonphotochemical quenching, fermentation, hydrogen peroxide biosynthesis, and defense responses to nematodes and water stress. The protein localizes to the apoplast, cell wall, vacuole, secretory vesicle, Golgi, mitochondria and cytosol. Associations with fruit weight, carotene and sugar content, chlorophyll content, photosynthetic rate, transpiration rate, root and shoot traits, seed maturation, germination rate, nitrate uptake, salt tolerance, drought tolerance, and resistance to pathogens including Verticillium dahliae and cyst nematode have been reported.
