Annotated Information

Function

This gene is an s-like Rnase gene. It related to the abscisic acid (ABA)-mediated responses and phytochrome-mediated light responses as well as salinity tolerance in rice. Recent study show that OsRNS4-OX lines have enhanced tolerance to high salinity compared to wild type and regulate photosensitivity and abiotic stress responses. It probably acts as a positive regulator in ABA responses in rice seedlings.

Expression

This gene was expressed at relatively high levels in leaves although its transcripts were detected in various organs. Its expression was regulated by salt, PEG and ABA. The seedlings overexpressing OsRNS4 had longer coleoptiles and first leaves than wild-type seedlings under red light and far-red light, suggesting negative regulation of OsRNS4 in photomorphogenesis in rice seedlings. Moreover, ABA-induced growth inhibition of rice seedlings was significantly increased in the OsRNS4-overexpression lines compared with that in wild type.

Evolution

The process of genome evolution by duplication in each species appears to have been quite different. Functional classifications of the proteins based on Gene Ontology (GO) annotations are shown in Figure 2; the numbers of known functional domains were not significantly different between the two species.
