BG1 — Capsicum annuum

Summary

CaBG1 (T459_10460) on pepper chromosome 3 encodes a glycosyl hydrolase family 17 protein with glucan exo-1,3-beta-glucosidase, endo-1,3-beta-D-glucosidase, lichenase, cellulase and O-glucosyl hydrolase activities, and also binds phosphorylated amino acids and other proteins. The gene is associated with defence responses to nematodes, fungi and bacteria, systemic acquired and induced resistance, hypersensitivity, cell death, brassinosteroid-mediated signalling, jasmonic acid signalling, response to cold, leaf formation, nitrogen fixation, virus-induced PTGS and carbohydrate metabolism. Its product localises to the secretory vesicle, vacuole, apoplast, plant-type cell wall, Golgi, mitochondria and cytosol. CaBG1 is linked to traits including leaf area index, stem diameter, plant height, photosynthetic rate, nitrate uptake, seedling growth, organ identity and leaf composition, as well as phenotypes such as anthocyanin accumulation, abscisic acid biosynthesis, phosphate acquisition, drought and salt tolerance, nematode and disease resistance, callose deposition and cellulose biosynthesis.
