PR3 — Camelina sativa

Summary

CsPR3 (CSA19G016730) in Camelina sativa encodes a chitinase with chitin-binding and glycosyl hydrolase family 19 domains, exhibiting chitinase activity and chitin binding. This gene is associated with chitin and polysaccharide breakdown, cell wall macromolecule catabolic processes, and carbohydrate metabolism. It is linked to defence responses against fungi, hypersensitive response-programmed cell death, and jasmonic acid/ethylene-dependent systemic resistance via ethylene-mediated signaling. CsPR3 is associated with ethylene sensitivity, nematode resistance, salt tolerance, seed germination under salt stress, wilt symptom development, and pathogen resistance. The encoded protein localizes to the protoplasm, secretory vesicles, vacuoles, and extracellular space. Related genes in other species link the family to disease resistance against Botrytis cinerea and pathogen defense.
