PR1 — Cicer arietinum

Summary

LOC101503659 (CaPR1) on chickpea chromosome 1 encodes a protein belonging to the CAP superfamily, with a CAP domain and CRISP-related region, and exhibits cytokine activity and protein binding. The gene is associated with defense responses to bacteria, fungi, herbivores, and wounding, as well as responses to salicylic acid, jasmonic acid, ethylene, and thiamin. It is linked to systemic acquired resistance, induced systemic resistance, immunity, and activation of immune response, along with processes including ethylene anabolism, nodulation, seed germination, sexual reproduction, and killing of cells of other organisms. CaPR1 localizes to the secretory vesicle, vacuole, plant-type cell wall, and extracellular space. Associations with drought tolerance, salt tolerance, cadmium response, and resistance to pathogens such as Rhizoctonia solani, Pseudomonas syringae, and Verticillium dahliae have been noted. Studies of related genes in other species link the family to pathogen resistance, systemic immunity, and abiotic stress tolerance.
