EP3 — Zea mays

Summary

ZmEP3 (ZM00001EB270440) on maize chromosome 6 encodes a protein with a glycosyl hydrolase 19 catalytic domain and lysozyme-like superfamily fold, and is annotated with chitinase activity (EC 3.2.1.14), chitin binding and protein binding. The gene is associated with chitin breakdown, polysaccharide breakdown, cell wall macromolecule catabolic process, ear development, tissue remodeling, shoot regeneration, secondary metabolite biosynthesis, fermentation, cell cycle control, and jasmonic acid/ethene-dependent systemic resistance. It localizes to the apoplast, plant-type cell wall, vacuole, secretory vesicle, protoplasm, plasmalemma, mitochondria and extracellular space. Associations include grain yield, plant height, stem diameter, ear diameter, root length, lignin content, glucose content, heterosis, ethylene sensitivity, and insect damage. Phenotype links include pathogen resistance, nematode resistance, salt tolerance, seed germination under salt stress, and wilt symptom development.
