BG2 — Brassica oleracea var. botrytis

Summary

BoBG2 (BG2) on cauliflower chromosome 8 encodes a glycosyl hydrolase family 17 protein with lichenase, cellulase, glucan exo-1,3-beta-glucosidase and glucan endo-1,3-beta-D-glucosidase activities. It is associated with carbohydrate metabolism, brassinosteroid-mediated signalling and response to cold. The protein localises to the secretory vesicle, vacuole, plant-type cell wall, apoplast, Golgi complex, mitochondria and cytosol. BoBG2 has been connected to nitrate uptake, organ identity, leaf composition, seedling growth and development, aphid susceptibility, defense and disease resistance, callose deposition, drought and salt tolerance, resistance to Verticillium dahliae, systemic acquired resistance, dehydration resistance, osmotic stress response, cellulose and callose biosynthesis, leaf development, cell proliferation and signal transduction. Studies of related genes in other species link the family to induced systemic resistance, pathogen and virus resistance, cell wall modification, disease resistance to Botrytis cinerea, organ size, calcium signalling and protein-protein interactions.
