PR1 — Oryza sativa Indica Group

Summary

BGIOSGA008188, designated PR1 (OiPR1) on Indica rice chromosome 2, encodes a protein belonging to the CRISP-related CAP domain family and is annotated with cytokine activity and protein binding. In Indica rice, PR1 is associated with defense responses, including resistance to root-knot nematode and responses to jasmonic acid, salicylic acid, ethylene, and gibberellin. It has been linked to seedling and root phenotypes, as well as to immune response activation, response to wounding, herbivory, and bacteria. The protein localizes to the extracellular region, plant-type cell wall, vacuole, and secretory vesicle. Studies of related genes in other species link the PR1 family to salicylic acid-mediated defense, systemic immunity, and resistance to pathogens such as Botrytis cinerea and Cucumber mosaic virus.
