PR1 — Oryza sativa Indica Group

Summary

BGIOSGA001599 (OiPR1) on chromosome 1 of indica rice encodes a protein with a CAP domain and V5 allergen-like family signature, annotated with cytokine activity and protein binding. The gene is associated with defense responses, including activation of immune response, response to herbivore, wounding, and pathogens such as Rhizoctonia solani and Pseudomonas syringae. It is linked to phytohormone signaling pathways, particularly salicylic acid, jasmonic acid, and ethylene, and to systemic acquired resistance. Associations also include responses to cadmium, salt stress, and acid rain, as well as lateral root development and resistance to root-knot nematode. The protein localizes to the secretory vesicle, vacuole, plant-type cell wall, and extracellular space.
