PR1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0473560 (HvPR1) on barley chromosome 5H encodes a protein belonging to the CAP superfamily, with a V5 allergen-like domain and associated cytokine activity and protein binding. The gene is associated with activation of immune response, cytokine production, and priming of cellular response to stress, as well as responses to salicylate, jasmonic acid, ethylene, wounding, herbivore, bacteria, and thiamin. It is associated with leaf senescence, embryogenesis, sexual reproduction, and proteolysis. The protein localises to the extracellular space, plant-type cell wall, vacuole, and secretory vesicles. HvPR1 is associated with disease resistance, systemic acquired resistance, salt tolerance, lateral root development, and resistance to Rhizoctonia solani and Pseudomonas syringae, as well as aphid resistance and cadmium response.
