EP3 — Oryza sativa Japonica

Summary

OsEP3 (OS10G0543400) encodes a chitinase with chitinase activity, beta-N-acetylglucosaminidase activity, and chitin binding, belonging to the Glyco_hydro_19_cat domain family. This rice gene on chromosome 10 is associated with chitin breakdown, cell wall macromolecule catabolic process, polysaccharide breakdown, and amino sugar metabolism. It is also associated with wax metabolism, diterpenoid metabolism, and cellulose anabolism. OsEP3 is localized extracellularly and is associated with multiple agronomic traits, including grain yield, grain weight, grain length, grain width, seed size, seed shape, seedling vigor, plant height, brittle culm, chlorophyll content, heat tolerance, and oxidative stress response. Related genes in other species are linked to bacterial leaf blight (BLB) resistance.
