PR1 — Camelina sativa

Summary

CsPR1 (CSA15G064830) on chromosome 15 of Camelina sativa encodes a protein containing a CAP (cysteine-rich secretory protein) domain. The gene product has been annotated with cytokine activity and protein binding, and is associated with cytokine production, activation of immune response, priming of cellular response to stress, defence responses to fungi and other organisms, and sexual reproduction. It localises to the secretory vesicle, vacuole, plant-type cell wall and extracellular space. CsPR1 is associated with salicylic acid signalling, systemic acquired resistance, induced systemic resistance, and resistance to a wide range of pathogens including Rhizoctonia solani, Pseudomonas syringae, Verticillium dahliae, and nematodes, as well as salt tolerance, cadmium response, acid rain response, and aphid resistance. Studies of related genes in other species connect the PR1 family to disease resistance, systemic immunity, herbivore defence, and abiotic stress tolerance.
