BG1 — Capsicum annuum

Summary

CaBG1 (T459_02123) on pepper chromosome 1 encodes a glucan endo-1,3-beta-glucosidase, basic isoform 2, a member of the glycosyl hydrolase 17 family with glucan exo-1,3-beta-glucosidase, lichenase, cellulase, and O-glucosyl hydrolase activities. The gene is associated with defense responses to nematodes and fungi, systemic acquired resistance, induced systemic resistance, JA signaling, brassinosteroid-mediated signaling, cell death, and response to cold and bacteria. It is linked to leaf area index, stem diameter, plant height, photosynthetic rate, nitrate uptake, and seedling growth traits, as well as anthocyanin accumulation, abscisic acid biosynthesis, phosphate acquisition, and tolerance to drought, salt, and biotic stress. The product localizes to the apoplast, cell wall, vacuole, secretory vesicle, Golgi, mitochondria, and cytosol. Related genes in other species link the family to nematode resistance and cell wall modification.
