PR1 — Medicago truncatula

Summary

MTR_2G435490, designated MtPR1, encodes a protein containing a CAP domain and a CRISP-related domain. The gene is associated with cytokine activity and protein binding, and its product localises to the secretory vesicle, vacuole, plant-type cell wall and extracellular space. MtPR1 is associated with defence responses against bacteria, fungi, herbivores and wounding, as well as with responses to salicylic acid, ethylene, jasmonic acid and thiamin. It is linked to systemic acquired resistance, induced systemic resistance, and resistance to Rhizoctonia solani, Pseudomonas syringae, Verticillium dahliae and Alternaria brassicicola. The gene is also associated with nitrogen fixation, sexual reproduction, salt tolerance, cadmium response, acid rain response, and priming of cellular response to stress. Related genes in other species link the family to salicylic acid-mediated defence, systemic immunity, and resistance to Cucumber mosaic virus and Botrytis cinerea.
