BG2 — Brassica napus

Summary

BnBG2 (DARMORV10_C08P32620.1) 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, lignin and phenylpropanoid anabolism, carbohydrate metabolism, leaf senescence, 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 and length, nitrate uptake, seedling growth, leaf composition, organ identity, aphid susceptibility, drought and salt tolerance, dehydration resistance, osmotic stress response, disease resistance including to Verticillium dahliae, callose deposition, cellulose biosynthesis, systemic acquired resistance, and pathogen defence. Related genes in other species are linked to pathogen and virus resistance, cell wall modification, organ size, calcium signalling and Botrytis cinerea resistance.
