PR1 — Triticum turgidum subsp. durum

Summary

TRITD5AV1G219430, designated PR1 on durum wheat chromosome 5A, encodes a CAP-domain-containing protein with cytokine activity and protein binding. The gene is associated with activation of immune response, cytokine production, and priming of cellular response to stress. It is linked to defence responses against bacteria, herbivores, and wounding, as well as responses to salicylate, jasmonic acid, and ethylene. Associations include systemic acquired resistance, disease resistance, salt tolerance, and responses to cadmium and acid rain. The product localises to the plant-type cell wall, vacuole, secretory vesicle, and extracellular space. Studies of related genes in other species connect the PR1 family to salicylic acid-mediated defence, pathogen resistance, and abiotic stress tolerance.
