Interpretive Summary: The flexibility of next-generation sequencing (NGS) technology allows almost any genetic material to be studied on a genome-wide scale. Complete and accurate genome sequencing are essential to facilitate full genome assemblies. Genetic characterization of RNA viruses using sequence-based methods is widely used to understand virus diversity, virus spread, understand origin and evolutionary history of viruses or to perform clinical diagnostics. In this study, we developed a simple template enrichment protocol that utilizes one universal primer to target all ten segments of the reovirus genome. This research will expand knowledge of these RNA viruses through examination of their complete genome.
Technical Abstract: The Reoviridae family represents the largest family of double-stranded RNA (dsRNA) viruses, and the members have been isolated from a wide range of mammals, birds, reptiles, fishes, in-sects, plants. Orthoreoviruses, one of the 15 recognized genera in the Reoviridae family, can infect humans and nearly all mammals, and birds. Genomic characterization of reovirses has not been adopted on a large-scale due to the complexity of obtaining sequences for all 10 segments. In this study, we developed a time-efficient, and practical method to enrich reovirus sequencing reads from isolates that allowed for full genome recovery using single-primer amplification method coupled with next generation sequencing. We refer to this protocol as reovirus-Single Primer Amplification (R-SPA). Our results demonstrated that most of the genes were covered with at least 500 reads per base space. Furthermore, R-SPA covered both 5' and 3' end of each reovirus genes. To conclude, a universal and fast amplification protocol that yields double-stranded cDNA in sufficient abundance and facilitates and expedites the whole genome sequencing of reoviruses was presented in this study.
