PR1 — Oryza sativa Indica Group

Summary

BGIOSGA025083, designated OiPR1 on indica rice chromosome 7, encodes a protein with a CAP domain (cysteine-rich secretory protein, allergen V5/Tpx-1 related) and is annotated with cytokine activity and protein binding. The gene is associated with immune and defense responses, including activation of immune response, cytokine production, and defense against bacteria, herbivores, and wounding. It is linked to responses to the phytohormones salicylic acid, jasmonic acid, and ethylene, and to systemic acquired resistance, disease resistance (including to root knot nematode and Rhizoctonia solani), and salt tolerance. Associations with cadmium and acid rain response, lateral root development, and secondary metabolite biosynthesis (diterpenoid and alkaloid) have also been noted. The encoded protein localizes to the extracellular space, plant-type cell wall, vacuole, and secretory vesicle.
