PR1 — Brachypodium distachyon

Summary

BdPR1 (BRADI_1G57590V3) on chromosome 1 of Brachypodium distachyon encodes a protein belonging to the CAP (cysteine-rich secretory proteins, antigen 5, and pathogenesis-related 1) superfamily, containing a CAP domain and a V5/Tpx1 conserved sequence, and is annotated with cytokine activity and protein binding. The gene is associated with activation of immune response, cytokine production, defense responses to bacteria, herbivores, and wounding, as well as responses to salicylic acid, jasmonic acid, and ethylene. It is linked to systemic acquired resistance, disease resistance, salt tolerance, and lateral root development. The encoded protein localizes to the extracellular space, plant-type cell wall, vacuole, and secretory vesicles. Studies of related genes in other species connect the family to pathogen resistance, salicylic acid-mediated defense, and abiotic stress tolerance.
