Genomic Analysis of a Novel <i>Torradovirus</i> "Rehmannia Torradovirus Virus": Two Distinct Variants Infecting <i>Rehmannia glutinosa</i>.

ABSTRACT: Rehmannia glutinosa, a crucial medicinal plant native to China, is extensively cultivated across East Asia. We used high-throughput sequencing to identify viruses infecting R. glutinosa with mosaic, leaf yellowing, and necrotic symptoms. A novel Torradovirus, which we tentatively named "Rehmannia torradovirus virus" (ReTV), was identified. The complete sequences were obtained through reverse-transcription polymerase chain reaction (RT-PCR), 5' and 3' rapid amplification of cDNA ends, and Sanger sequencing. The amino acid sequence alignment between the ReTV-52 isolate and known Torradovirus species in the Pro-Pol and coat protein regions were 51.3-73.3% and 37.1-68.1%, respectively. Meanwhile, the amino acid sequence alignment between the ReTV-8 isolate and known
