EP3 — Brachypodium distachyon

Summary

BdEP3 (BRADI_2G47191V3) on chromosome 2 of Brachypodium distachyon encodes a chitinase with beta-N-acetylglucosaminidase and protein serine/threonine kinase activities, binding chitin, ATP and proteins. It is associated with chitin and polysaccharide breakdown, cell wall macromolecule catabolism, amino sugar metabolism, and responses to fungi, bacteria, oomycetes, insects, viruses, amitrole, silver ion, hypoxia, and leaf senescence. The gene is associated with systemic acquired resistance, jasmonic acid/ethylene-dependent systemic resistance, hypersensitive response cell death, and somatic embryogenesis. Its product localises to the apoplast, cell wall, vacuole, secretory vesicle, membrane, mitochondria and extracellular space. Associations with ethylene sensitivity, pathogen resistance, salt tolerance, seed germination under salt stress, nematode resistance and wilt symptom development have been noted. Studies of related genes in other species connect the family to disease resistance, growth, and grain traits.
