BG2 — Brassica napus

Summary

BnBG2 (DARMORV10_C08P32600.1) on chromosome C08 of oilseed rape (Brassica napus) 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 possesses protein binding and protein phosphorylated amino acid binding functions. The gene is associated with induced systemic resistance, brassinosteroid-mediated signalling, leaf senescence, programmed cell death, response to cold, and auxin, lignin and phenylpropanoid anabolism. It is linked to root weight, root length, nitrate uptake, seedling growth and development, leaf composition, organ identity, aphid susceptibility, defense response, disease resistance, callose deposition, drought tolerance, resistance to Verticillium dahliae, systemic acquired resistance, stress response, pathogen 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 apoplast, plant-type cell wall, vacuole, secretory vesicle, Golgi complex, mitochondria and cytosol. Studies of related genes in other species link the family to pathogen resistance, virus resistance, cell wall modification, organ size and calcium signalling.
