PR1 — Oryza sativa Japonica

Summary

OsPR1 (OS01G0382000) encodes a protein containing a CAP (cysteine-rich secretory protein, allergen V5-like) domain. The gene is associated with cytokine activity and protein binding, and its product localises to the extracellular space, secretory vesicles, vacuole and plant-type cell wall. OsPR1 is associated with defence-related processes, including systemic acquired resistance, induced systemic resistance, and responses to salicylic acid, jasmonic acid, ethylene and gibberellin. It is linked to resistance against root-knot nematode, Rhizoctonia solani and Pseudomonas syringae, as well as to aphid resistance and salt tolerance. Associations with agronomic traits include grain weight, grain yield, tiller number, plant height, chlorophyll content and anthocyanin content. Related genes in other species are linked to salicylic acid-mediated defence and resistance to Botrytis cinerea and Cucumber mosaic virus.
