BG2 — Brassica napus

Summary

BnBG2 (DARMORV10_C08P32590.1) 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 include root weight, nitrate uptake, root length, leaf composition, seedling growth, aphid susceptibility, 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 link the family to pathogen resistance, virus resistance, cell wall modification, organ size and calcium signalling.
