PR1 — Oryza sativa Japonica

Summary

OsPR1 (OS07G0128800) in rice encodes a protein belonging to the CAP (cysteine-rich secretory protein, antigen 5, and pathogenesis-related 1) superfamily, characterized by a CAP domain and a CRISP-related motif. This gene is associated with a wide range of biological processes, including regulation of protein kinase C activity, antibody production, cellular response to toxic substances, regulation of hormone levels, retrotransposition, appressorium formation, hyphal growth, translation termination, nuclear import, pigmentation, salicylic acid anabolism, secretion, syngamy, protein synthesis, and anthocyanin anabolism. The encoded protein is localized to the extracellular region and the vacuole. Associations with agronomically important traits include grain size, grain yield, plant height, chlorophyll a and b content, total chlorophyll content, and anthocyanin content. Related genes in other species are linked to pathogenesis-related protein 1.
