Rice is a staple food for over one-half of the world population, especially in Asian countries. Recently, the growth and yield of crop plants was affected by various abiotic stresses, such as salt, drought, and high temperature due to change of climate environment. To study molecular functions of Oryza sativa nuclear-targeted RING Finger Proteins (OsNRFPs) in response to abiotic stresses, we selected 44 OsNRFPs genes, whose subcelluar localizations are predicted to the nucluear, on the basis of expression patterns of a microarray dataset. A total of 44 OsNRFPs were grouped into two types such as RING-HC and RING-H2 via phylogeneitc analysis of their RING domains structures. Subsequently, we surveyed the expression patterns of 44 genes in response to salt stress via qRT-PCR in roots. We found 10 salt stress-induced OsNRFPs and then examined their subcellular localizations. These genes were clearly localized to the nucleus (OsNRFPHC-10), cytoplasm (OsNRFPHC-17 and OsNRFPH2-16) and microtuble (OsNRFPHC-23, OsNRFPH2-17 and OsNRFPH2-05), respectively. These results might provide a key clue for understanding moleuclar functions of the OsNRFP genes associated with salt stress-related signaling pathway
