BG2 — Brassica napus

Summary

BnBG2 (BG2), located on chromosome A09 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 is also associated with protein phosphorylated amino acid binding and protein binding. This gene is linked to induced systemic resistance, auxin anabolism, lignin anabolism, phenylpropanoid anabolism, carbohydrate metabolism, leaf senescence, cell death, programmed cell death, brassinosteroid mediated signalling, and response to cold. It is associated with root weight, nitrate uptake, root length, leaf composition, seedling growth, aphid susceptibility, defense response, disease resistance, callose deposition, drought tolerance, resistance to Verticillium dahliae, systemic acquired resistance, stress response, pathogen response, pathogen defense 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 secretory vesicles, vacuoles, the plant-type cell wall, apoplast, Golgi complex, mitochondria, and cytosol. Studies of related genes in other species link the family to pathogen resistance, virus resistance, cell wall modification, and organ size.
