PR1 — Triticum turgidum subsp. durum

Summary

TRITD5BV1G216890, designated TtPR1 on durum wheat chromosome 5B, encodes a protein with cytokine activity and protein binding functions. The gene is associated with activation of immune response, cytokine production, and priming of cellular response to stress. It is linked to defense responses against bacteria, herbivores, and wounding, as well as responses to salicylate, jasmonic acid, and ethylene. TtPR1 is associated with systemic acquired resistance, disease resistance, and salt tolerance. The encoded protein localizes to the plant-type cell wall, vacuole, secretory vesicle, and extracellular space. Studies of related genes in other species link the family to pathogen resistance, salicylic acid-mediated defense, and abiotic stress tolerance.
