EP3 — Oryza sativa Indica Group

Summary

BGIOSGA023632 (EP3, OiEP3) on chromosome 6 of Indica rice encodes a chitinase with chitin-binding and glycosyl hydrolase family 19 domains, exhibiting chitinase and beta-N-acetylglucosaminidase activity. This gene is associated with chitin breakdown, polysaccharide breakdown, cell wall macromolecule catabolic process, cell wall modification, membrane biogenesis, amino sugar metabolism, carbohydrate metabolism, and defence response to fungi. It is also linked to transposition, killing of cells of other organisms, and extracellular localisation. Additionally, EP3 has been associated with drought tolerance. Studies of related genes in other species link the family to similar chitinolytic and defence functions.
