EP3 — Oryza sativa Indica Group

Summary

BGIOSGA033387 (EP3, OiEP3) on chromosome 10 of Indica rice encodes a chitinase (EC 3.2.1.14) with chitin-binding and chitinase activity, belonging to the Glyco_hydro_19 family. This gene is associated with chitin breakdown, cell wall macromolecule catabolic process, cell wall modification, membrane biogenesis, polysaccharide breakdown, carbohydrate metabolism, and defence response to fungi. It is also linked to transposition and is localised extracellularly. Additionally, EP3 has been connected to drought tolerance. Studies of related genes in other species further link the family to defence-related functions.
