Nemesia ring necrosis virus: a new tymovirus with a genomic RNA having a histidylatable tobamovirus-like 3' end.
The complete nucleotide sequence of the genomic RNA of the new virus Nemesia ring necrosis virus (NeRNV), which is widespread in various ornamental plant species belonging to the Scrophulariaceae and Verbenaceae, has been determined. Based on its gene content, the folding properties of its 5'-untranslated region and in vitro translation experiments, NeRNV RNA is a typical tymovirus RNA. Its 3' end, however, differs greatly from those of the valine-specific tymoviral RNAs that have been analysed previously. It can be folded into an upstream pseudoknot domain and a histidine-specific tRNA-like structure, a combination that, so far, has been found only in tobamoviral RNAs. The identity elements found in NeRNV RNA for recognition by yeast histidyl-tRNA synthetase are more similar to those of yeast tRNAHis than the ones found in tobacco mosaic virus RNA. As a result NeRNV RNA can be charged with histidine even more efficiently than tobacco mosaic virus RNA.
