PR3 — Glycine max

Summary

GmPR3 (GLYMA_02G042500V4) on soybean chromosome 2 encodes a protein with chitin-binding and glycosyl hydrolase family 19 domains, possessing chitinase activity and chitin binding. This gene is associated with chitin breakdown, cell wall macromolecule catabolic process, polysaccharide breakdown, and immune response. It is linked to ethylene sensitivity, jasmonic acid/ethene-dependent systemic resistance, MAPK cascade, and phenylpropanoid and flavonoid anabolism. Associations include salt tolerance, nematode resistance, pathogen resistance, seed germination under salt stress, root number, lateral root number, chlorophyll content, and hydrogen peroxide content. The encoded protein localizes to the extracellular space, vacuole, and secretory vesicles. Related genes in other species link the family to plant height and disease tolerance.
