EP3 — Oryza sativa Indica Group

Summary

BGIOSGA001867 (EP3, OiEP3) on chromosome 1 of Indica rice encodes a protein with Glyco_hydro_19 and lysozyme-like domains, possessing chitinase activity (EC 3.2.1.14), chitin binding and protein binding. The gene is associated with chitin and polysaccharide breakdown, cell wall modification, membrane biogenesis, somatic embryogenesis, leaf senescence, and responses to fungi, oomycetes, insects, viruses, amitrole, silver ion, hypoxia, and systemic acquired resistance. It is linked to ethylene sensitivity, drought tolerance, pathogen resistance, salt tolerance, seed germination under salt stress, nematode resistance, and growth. The protein localizes to the apoplast, cell wall, vacuole, secretory vesicle, plasma membrane, mitochondria, and extracellular space. Related genes in other species link the family to pollen tube growth and disease resistance to Botrytis cinerea.
