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, and 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 is linked to nitrate uptake, organ identity, leaf composition, seedling growth, aphid susceptibility, defense and disease resistance, callose deposition, drought and salt tolerance, dehydration resistance, osmotic stress response, cellulose and callose biosynthesis, leaf development, cell proliferation, signal transduction and nitrate assimilation. Studies of related genes in other species connect 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.
