BG2 — Brassica oleracea var. botrytis

Summary

BoBG2, located on chromosome 8 of cauliflower (Brassica oleracea var. botrytis), 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 also exhibits protein binding and protein phosphorylated amino acid binding. This gene is associated with carbohydrate metabolism, brassinosteroid-mediated signalling, and response to cold. It is linked to traits including nitrate uptake, organ identity, leaf composition, and seedling growth and development. Phenotypic associations include 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. The protein localises to the secretory vesicle, vacuole, plant-type cell wall, apoplast, Golgi complex, mitochondria, and cytosol. Studies of related genes in other species link the family to induced systemic resistance, pathogen resistance, virus resistance, cell wall modification, and organ size.
