BG1 — Solanum tuberosum

Summary

StBG1 (PGSC0003DMG400020017) on potato chromosome 1 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 proteins. The gene is associated with glucan and carbohydrate metabolism, autolysis, cell death, brassinosteroid-mediated signalling, and responses to cold, bacteria, fungi, viruses and nematodes, as well as induced and systemic acquired resistance. It is linked to traits including photosynthetic rate, nitrate uptake, leaf composition, seedling growth and organ identity, and to phenotypes such as anthocyanin accumulation, abscisic acid biosynthesis, phosphate acquisition, biotic stress tolerance, nematode resistance, salt and drought tolerance, callose deposition, and resistance to Verticillium dahliae. The protein localises to the apoplast, plant-type cell wall, vacuole, Golgi, secretory vesicles, mitochondria and cytosol.
