BG1 — Capsicum annuum

Summary

CaBG1 (T459_26521) on pepper chromosome 10 encodes a lichenase with glucan exo-1,3-beta-glucosidase, lichenase, cellulase, and glucan endo-1,3-beta-D-glucosidase activities, belonging to the glycosyl hydrolase 17 family. The gene is associated with defense responses to nematodes and fungi, systemic acquired and induced resistance, virus-induced PTGS, immune response, brassinosteroid-mediated signaling, jasmonic acid signaling, cell death, response to cold and bacteria, carbohydrate metabolism, leaf formation, and nitrogen fixation. Its product localizes to the apoplast, plant-type cell wall, vacuole, secretory vesicle, Golgi complex, mitochondria, and cytosol. CaBG1 has been linked to plant height, stem diameter, leaf area index, photosynthetic rate, seedling growth, disease tolerance, nitrate uptake, and leaf composition. Related genes in other species connect the family to nematode resistance and callose deposition.
