PR1 — Oryza sativa Japonica

Summary

OsPR1 (OS07G0127600) encodes a protein containing a CAP (cysteine-rich secretory protein, allergen V5, and pathogenesis-related 1) domain, a member of the V5-allergen-like family, and is associated with cytokine activity and protein binding. In rice, this gene is linked to seedling development, jasmonic acid and phytohormone responses, and is associated with defence-related processes including systemic acquired resistance, disease resistance, and responses to herbivores, pathogens, and toxic substances. It is also associated with traits such as chlorophyll content, grain size, plant height, grain yield, anthocyanin content, and salt tolerance. The encoded protein localises to the secretory vesicle, vacuole, plant-type cell wall, and extracellular space. Related genes in other species are linked to salicylic acid-mediated defence, systemic immunity, and resistance to fungal pathogens and insects.
