PR1 — Camelina sativa

Summary

CsPR1 (CSA19G044900) on Camelina sativa chromosome 19 encodes a protein containing a CAP domain and a CRISP-related Allrgn_V5/Tpx1_CS domain, with cytokine activity and protein binding functions. The gene is associated with immune response activation, defense against fungi and other organisms, cytokine production, sexual reproduction, and cellular stress priming. It localizes to secretory vesicles, vacuoles, the plant-type cell wall, and extracellular regions. CsPR1 is associated with systemic acquired resistance, salicylic acid signaling, biotic stress resistance including resistance to 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 link the PR1 family to disease resistance, fungal resistance, herbivore defense, and abiotic stress tolerance.
