PR3 — Camelina sativa

Summary

CsPR3 (CSA15G016380) encodes a protein with a glycosyl hydrolase family 19 catalytic domain and a chitin-binding domain, and is annotated with chitinase activity and chitin binding. In Camelina sativa, this gene is associated with chitin breakdown, cell wall macromolecule catabolism, defence response to fungi, hypersensitive response-programmed cell death, and jasmonic acid/ethene-dependent systemic resistance. It is linked to ethylene sensitivity, nematode resistance, salt tolerance, seed germination under salt stress, and pathogen resistance. The encoded protein localises to the protoplasm, secretory vesicles, vacuole, and extracellular space. Studies of related genes in other species connect the family to disease resistance against Botrytis cinerea and broader pathogen defense.
