PR1 — Oryza sativa Indica Group

Summary

BGIOSGA025087 (symbol PR1, also known as OiPR1) on chromosome 7 of Indica rice encodes a protein containing a CAP domain and V5 allergen-like family domain, with annotated cytokine activity and protein binding. The gene is associated with immune response activation, defense responses to bacteria, herbivores, and wounding, as well as responses to jasmonic acid, ethylene, and salicylic acid. It has been linked to seedling and root phenotypes, resistance to root knot nematode, and interactions with phytohormones including jasmonate, gibberellin, and salicylate. The encoded product localizes to the secretory vesicle, vacuole, plant-type cell wall, and extracellular space. Additional associations include systemic acquired resistance, disease resistance to various pathogens, salt tolerance, lateral root development, and responses to cadmium and acid rain.
