PR1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0651300 (symbol PR1, HvPR1) on barley chromosome 7H encodes a protein of the CAP superfamily, containing a V5 allergen-like domain and a CRISP-related domain. The gene is associated with systemic acquired resistance, induced systemic resistance, immune response, defense response to other organisms, and leaf senescence. It is also linked to embryogenesis, proteolysis, and signal transduction. The encoded protein localises to the extracellular region and vacuole. HvPR1 has been connected to hydrogen peroxide content. Related genes in other species link this gene family to pathogenesis-related proteins.
