PR1 — Pisum sativum

Summary

PsPR1 (PSAT1G156240) on garden pea chromosome 1LG6 encodes a protein containing a CAP domain and belonging to the CRISP-related family. The protein exhibits cytokine activity and protein binding, and is localised to the extracellular space, plant-type cell wall, vacuole, and secretory vesicles. PsPR1 is associated with activation of immune response, defense response to other organisms, response to herbivore, wounding, jasmonic acid, ethylene, salicylate, and bacteria, as well as cell cycle control, G1 phase, sexual reproduction, and priming of cellular response to stress. It is linked to systemic acquired resistance, induced systemic resistance, biotic stress resistance, and specific resistances to Rhizoctonia solani, Pseudomonas syringae, and Verticillium dahliae. The gene is also associated with salt tolerance, cadmium response, acid rain response, and UV-C response. Studies of related genes in other species connect the family to pathogen resistance, fungal disease resistance, herbivore defense, and abiotic stress tolerance.
