BG2 — Brassica napus

Summary

BnBG2 (DARMORV10_C08P32610.1) on chromosome C08 of oilseed rape encodes a glycosyl hydrolase family 17 protein with lichenase, cellulase, and glucan endo-1,3-beta-D-glucosidase activities. The gene is associated with induced systemic resistance, brassinosteroid-mediated signalling, leaf senescence, programmed cell death, and response to cold. It has been linked to root weight, root length, nitrate uptake, seedling growth and development, leaf composition, and organ identity. Phenotypic associations include disease resistance, drought tolerance, salt tolerance, osmotic stress response, callose deposition, aphid susceptibility, and resistance to Verticillium dahliae. The encoded protein localises to the plant-type cell wall, apoplast, vacuole, 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.
