PR1 — Oryza sativa Indica Group

Summary

BGIOSGA003568, designated PR1 (synonyms OiCAPE7, OiPR1, PRMS), on chromosome 1 of Indica rice encodes a protein belonging to the CRISP-related CAP domain family and is annotated with cytokine activity and protein binding. The gene is associated with defense responses, including activation of immune response, response to herbivore, wounding, jasmonic acid, ethylene, and salicylate, as well as systemic acquired resistance and resistance to Rhizoctonia solani and root knot nematode. It is linked to phytohormone signaling (jasmonate, salicylic acid, gibberellin) and traits like seedling and root development. The encoded protein localizes to the secretory vesicle, vacuole, plant-type cell wall, and extracellular space. Studies of related genes in other species connect the family to salicylic acid-mediated defense, pathogen resistance, and abiotic stress tolerance.
