EP3 — Brachypodium distachyon

Summary

BdEP3 (BRADI_2G36780V3) on Brachypodium distachyon chromosome 2 encodes a protein with a Glyco_hydro_19 domain, beta-N-acetylglucosaminidase activity, chitinase activity (EC 3.2.1.14), chitin binding, and protein binding. It is associated with chitin and polysaccharide breakdown, amino sugar and carbohydrate metabolism, cell wall macromolecule catabolism, and responses to amitrole, silver ion, oomycetes, insects, viruses, fungi, bacteria, hypoxia, and jasmonic acid/ethylene-dependent systemic resistance, as well as leaf senescence, somatic embryogenesis, systemic acquired resistance, and HR-PCD. The protein localizes to the apoplast, plant-type cell wall, vacuole, secretory vesicle, and extracellular space. Associations with pathogen resistance, salt tolerance, seed germination under salt stress, and ethylene sensitivity have been noted. Studies of related genes in other species link the family to disease resistance, growth, and grain traits.
