BG2 — Brassica napus

Summary

BnBG2 (DARMORV10_C08P32580.1) on chromosome C08 of oilseed rape 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. The gene is associated with induced systemic resistance, auxin anabolism, lignin anabolism, phenylpropanoid anabolism, carbohydrate metabolism, leaf senescence, cell death, programmed cell death, brassinosteroid-mediated signalling and cold response. Its product localises to the secretory vesicle, vacuole, plant-type cell wall, apoplast, Golgi, mitochondria and cytosol. Associations with root weight, nitrate uptake, root length, organ identity, leaf composition, seedling growth and development, 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 have been reported. Studies of related genes in other species link the family to pathogen resistance, virus resistance, cell wall modification, organ size and calcium signalling.
