BG1 — Beta vulgaris subsp. vulgaris

Summary

BvBG1 (BVRB_3G062130) on sugar beet chromosome 3 encodes a protein with glucan exo-1,3-beta-glucosidase, lichenase, cellulase, and glucan endo-1,3-beta-D-glucosidase activities, belonging to the glycosyl hydrolase family 17. The gene is associated with defense responses to nematodes, fungi, and bacteria, systemic acquired resistance, brassinosteroid-mediated signaling, and cold response. It has been linked to traits including photosynthetic rate, nitrate uptake, leaf composition, seedling growth, and organ identity, as well as phenotypes such as anthocyanin accumulation, abscisic acid biosynthesis, phosphate acquisition, and tolerance to biotic and abiotic stresses including drought, salt, dehydration, and osmotic stress. The encoded protein localizes to the apoplast, plant-type cell wall, vacuole, secretory vesicle, Golgi, mitochondria, and cytosol. Related genes in other species connect the family to nematode resistance and cell wall modification.
