EP3 — Brachypodium distachyon

Summary

BdEP3 (BRADI_5G14430V3) on chromosome 5 of Brachypodium distachyon encodes a protein with chitinase activity (EC 3.2.1.14), chitin binding and protein binding functions, belonging to the glycosyl hydrolase 19 family. The gene is associated with chitin and polysaccharide breakdown, cell wall macromolecule catabolism, and amino sugar metabolism. It is linked to responses to fungi, bacteria, oomycetes, viruses, and insects, as well as to systemic acquired resistance, jasmonic acid/ethylene-dependent systemic resistance, hypersensitive response-programmed cell death, leaf senescence, somatic embryogenesis, and cellular response to hypoxia. The protein localizes to the apoplast, cell wall, vacuole, secretory vesicles, and plasma membrane. Associations with ethylene sensitivity, pathogen resistance, salt tolerance, seed germination under salt stress, and nematode resistance have been reported.
