BG2 — Brassica oleracea var. botrytis

Summary

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