EP3 — Brachypodium distachyon

Summary

BdEP3 (BRADI_1G29880V3) on chromosome 1 of Brachypodium distachyon encodes a protein with Glyco_hydro_19 and lysozyme-like domains, exhibiting chitinase, beta-N-acetylglucosaminidase, chitin-binding and protein-binding activities (EC 3.2.1.14). The gene is associated with chitin and polysaccharide breakdown, cell wall macromolecule catabolism, amino sugar metabolism, and responses to fungi, bacteria, oomycetes, insects, viruses, silver ions, amitrole, hypoxia, and leaf senescence. It is linked to systemic acquired resistance, jasmonic acid/ethylene-dependent systemic resistance, hypersensitive response-programmed cell death, and somatic embryogenesis. The encoded protein localizes to the apoplast, plant-type cell wall, vacuole, secretory vesicle, plasma membrane, mitochondria, and extracellular space. BdEP3 is associated with ethylene sensitivity, pathogen resistance, salt tolerance, seed germination under salt stress, nematode resistance, and wilt symptom development.
