BG2 — Brassica napus

Summary

BnBG2 (DARMORV10_A09P50170.1) on chromosome A09 of oilseed rape (Brassica napus) encodes a glycosyl hydrolase family 17 protein with glucan endo-1,3-beta-D-glucosidase, glucan exo-1,3-beta-glucosidase and cellulase activities, and also binds proteins and phosphorylated amino acids. The gene is associated with induced systemic resistance, brassinosteroid-mediated signalling, auxin, lignin and phenylpropanoid anabolism, carbohydrate metabolism, leaf senescence, programmed cell death, and cold response. It localises to the cell wall, apoplast, vacuole, Golgi, mitochondria and cytosol. Associations include root weight and length, nitrate uptake, seedling growth, leaf development, drought and salt tolerance, dehydration resistance, osmotic stress response, aphid susceptibility, disease resistance, callose deposition and biosynthesis, and defence against Verticillium dahliae. Studies of related genes in other species link the family to pathogen resistance, virus resistance, cell wall modification, organ size and calcium signalling.
