BG1 — Solanum tuberosum

Summary

PGSC0003DMG400029830 (BG1, also known as TOMQB, StGNS1, and PR-2) on potato chromosome 10 encodes a protein belonging to the glycosyl hydrolase family 17, with glucan exo-1,3-beta-glucosidase, lichenase, cellulase, and glucan endo-1,3-beta-D-glucosidase activities. The protein is associated with defense responses to nematodes, viruses, bacteria, and fungi, as well as induced systemic resistance, systemic acquired resistance, and virus-induced PTGS. It is linked to brassinosteroid-mediated signaling, cell death, cold response, and carbohydrate metabolism. The protein localizes to the apoplast, plant-type cell wall, vacuole, secretory vesicles, Golgi complex, mitochondria, and cytosol. Associations with agronomic traits include nitrate uptake, photosynthetic rate, leaf composition, seedling growth, organ identity, anthocyanin accumulation, abscisic acid biosynthesis, phosphate acquisition, nematode resistance, disease resistance, salt tolerance, drought tolerance, and resistance to Verticillium dahliae.
