PR1 — Oryza sativa Japonica

Summary

OsPR1 (OS07G0126100) encodes a protein belonging to the CAP (cysteine-rich secretory proteins, antigen 5, and pathogenesis-related 1) superfamily, characterized by a CAP domain and a CRISP-related motif. In rice, this gene is associated with diverse biological processes including regulation of hormone levels, cellular response to toxic substances, salicylic acid anabolism, anthocyanin anabolism, appressorium formation, hyphal growth, pigmentation, and secretion. It is linked to extracellular and vacuolar localization. Associations with agronomically important traits include grain size, grain yield, plant height, chlorophyll content (including chlorophyll a and b), and anthocyanin content. Studies of related genes in other species link the family to pathogenesis-related responses.
