Chi1 — Triticum aestivum

Summary

TRAESCS4D02G325300 (symbol Chi1) on bread wheat chromosome 4D encodes a chitinase, a member of the glycoside hydrolase family 19 catalytic domain and lysozyme-like domain superfamily. The enzyme exhibits chitinase activity (EC 3.2.1.14), beta-N-acetylglucosaminidase activity, and chitin binding. It is associated with chitin breakdown, cell wall macromolecule catabolism, amino sugar metabolism, polysaccharide breakdown, defence response to fungi, and killing of cells of other organism. The protein localises to the vacuole and extracellular space. Related genes in other species link the family to Fusarium head blight resistance.
