PR1 — Oryza sativa Japonica

Summary

OsPR1 (OS07G0125000) encodes a protein containing a CAP (cysteine-rich secretory protein, allergen V5, and pathogenesis-related 1) domain. The gene product has been annotated with cytokine activity and protein binding, and localises to the secretory vesicle, vacuole, plant-type cell wall and extracellular space. In rice, OsPR1 is associated with responses to jasmonic acid, salicylic acid, and pathogen defence, including resistance to root-knot nematode. It has also been linked to seedling and shoot phenotypes, and to traits such as grain weight, grain yield, tiller number, plant height, chlorophyll content, anthocyanin content, and salt tolerance. Additional associations include systemic acquired resistance, defence against herbivores and fungal pathogens, and responses to cadmium and acid rain.
