BG1 — Phaseolus vulgaris

Summary

PHAVU_001G128500, designated PvBG1 on French bean chromosome 1, encodes a member of the glycosyl hydrolase family 17, with annotated glucan exo-1,3-beta-glucosidase, lichenase, cellulase and glucan endo-1,3-beta-D-glucosidase activities. The product is associated with carbohydrate metabolism, brassinosteroid-mediated signalling, nodulation, and responses to bacteria and cold. It localises to the apoplast, plant-type cell wall, vacuole, Golgi, secretory vesicle, cytosol, mitochondria and extracellular space. PvBG1 is associated with leaf composition, seedling growth, organ identity, nitrate uptake and assimilation, phosphate acquisition, abscisic acid biosynthesis, anthocyanin accumulation, callose deposition and biosynthesis, cellulose biosynthesis, drought tolerance, salt tolerance, dehydration resistance, osmotic stress response, aphid susceptibility, disease resistance including to Verticillium dahliae, systemic acquired resistance, and leaf development and cell proliferation. Studies of related genes in other species link the family to induced systemic resistance, pathogen and virus resistance, cell wall modification, organ size, calcium signalling and protein-protein interactions.
