EP3 — Oryza sativa Japonica

Summary

OS01G0287600 (EP3, also known as Cht10) encodes a protein with chitinase activity, beta-N-acetylglucosaminidase activity and chitin binding, belonging to the glycoside hydrolase family 19. The encoded protein is localised to the apoplast, cell wall, vacuole and secretory vesicles. In rice, this gene is associated with chitin breakdown, cell wall macromolecule catabolism, polysaccharide breakdown, amino sugar metabolism, wax metabolism, diterpenoid metabolism, and responses to amitrole and silver ions. It is linked to the jasmonic acid/ethylene-dependent systemic resistance pathway. Agronomically, EP3 is associated with grain yield, grain weight, grain length and width, seed size and shape, seedling vigor, plant height, brittle culm, cellulose content, chlorophyll content, heat tolerance, salt tolerance, germination rate, ethylene sensitivity, and pathogen resistance.
