BG1 — Cucumis sativus

Summary

CSA_1G660200 (BG1, also known as PR-2) on cucumber chromosome 1 encodes a beta-1,3-endoglucanase with glucan exo-1,3-beta-glucosidase, lichenase, cellulase, and glucan endo-1,3-beta-D-glucosidase activities. This gene is associated with defense responses to nematodes, fungi, and bacteria, as well as systemic acquired resistance, appressorium formation, and brassinosteroid-mediated signaling. It is linked to fruit development and ripening, carbohydrate metabolism, fermentation, hydrogen peroxide biosynthesis, reactive oxygen species metabolism, and responses to cold. The encoded protein localizes to the apoplast, plant-type cell wall, vacuole, secretory vesicle, Golgi complex, mitochondria, and cytosol. Associations with powdery mildew resistance, nematode resistance, drought tolerance, salt tolerance, dehydration resistance, osmotic stress response, phosphate acquisition, anthocyanin accumulation, abscisic acid biosynthesis, and nitrate uptake have been observed.
