BG2 — Brassica napus

Summary

BnBG2 (DARMORV10_C08P32630.1) 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, and also binds protein and phosphorylated amino acids. The gene is associated with induced systemic resistance, brassinosteroid-mediated signalling, leaf senescence, programmed cell death, cold response, and auxin, lignin and phenylpropanoid anabolism. Its product localises to the apoplast, plant-type cell wall, vacuole, Golgi, mitochondria and cytosol. BG2 is associated with root weight and length, nitrate uptake and assimilation, seedling growth, leaf composition, organ identity, drought and salt tolerance, dehydration and osmotic stress resistance, aphid susceptibility, callose deposition and biosynthesis, cellulose biosynthesis, and resistance to Verticillium dahliae. Studies of related genes in other species link the family to pathogen and virus resistance, Botrytis cinerea resistance, cell wall modification, organ size, calcium signalling and protein-protein interactions.
