PR1 — Brachypodium distachyon

Summary

BdPR1 (BRADI_1G12360V3) 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-related conserved sequence. The product is annotated with cytokine activity and protein binding, and is associated with activation of immune response, cytokine production, priming of cellular response to stress, defense response to other organism, response to herbivore, response to wounding, and responses to salicylic acid, jasmonic acid, ethylene, and thiamin. It localizes to the extracellular space, plant-type cell wall, vacuole, and secretory vesicles. Phenotypic associations include disease resistance, systemic acquired resistance, salt tolerance, lateral root development, and resistance to Rhizoctonia solani and Pseudomonas syringae. Related genes in other species link the PR1 family to salicylic acid-mediated defense, fungal disease resistance, and abiotic stress tolerance.
