EP3 — Brachypodium distachyon

Summary

BdEP3 (BRADI_2G26018V3) on chromosome 2 of Brachypodium distachyon encodes a protein with glycosyl hydrolase family 19 and chitin-binding domains, exhibiting chitinase, beta-N-acetylglucosaminidase, chitin-binding and protein-binding activities. The gene is associated with chitin and polysaccharide breakdown, cell wall macromolecule catabolism, amino sugar metabolism, and responses to fungi, bacteria, oomycetes, insects, viruses, amitrole, silver ions, hypoxia, and leaf senescence. It is associated with systemic acquired resistance, jasmonic acid/ethylene-dependent defence signalling, hypersensitive response-programmed cell death, somatic embryogenesis, and killing of other organisms. The encoded protein localises to the apoplast, cell wall, vacuole, secretory vesicles, plasma membrane, mitochondria and extracellular space. BdEP3 is associated with pathogen resistance, salt tolerance, seed germination under salt stress, ethylene sensitivity, nematode resistance and wilt symptom development.
