PR1 — Camelina sativa

Summary

CsPR1 (CSA01G035420) on Camelina sativa chromosome 1 encodes a protein containing a CAP (cysteine-rich secretory protein) domain, characteristic of the PR-1 family, and exhibits cytokine activity and protein binding. This gene is associated with immune activation, defense responses to fungi and other organisms, and systemic acquired resistance. It has been linked to salicylic acid signaling, biotic stress resistance including resistance to Rhizoctonia solani, Pseudomonas syringae, and Verticillium dahliae, as well as salt tolerance, aphid resistance, and nematode resistance. Additional associations include responses to cadmium, acid rain, and thiamin, along with sexual reproduction and priming of cellular stress responses. The encoded protein localizes to secretory vesicles, the plant cell wall, vacuole, and extracellular space. Studies of related genes in other species connect the PR-1 family to disease resistance, systemic immunity, and abiotic stress tolerance.
