Summary
Long-read sequencing provides new insights into viral transcriptomes, aiding in the study of emerging zoonotic RNA viruses and host responses. This research details nanopore sequencing data for six key human pathogen RNA viruses.
Area of Science:
- Virology
- Genomics
- Bioinformatics
Background:
- Emerging RNA viruses pose significant public health threats, as exemplified by influenza and SARS-CoV-2.
- Long-read sequencing (LRS) technologies offer advanced capabilities for analyzing complex transcriptomes.
- Understanding viral RNA complexity is crucial for developing effective countermeasures.
Purpose of the Study:
- To generate and analyze transcriptomic data for six significant human pathogen RNA viruses using nanopore sequencing.
- To investigate the host cell response to viral infection at the transcriptomic level.
- To provide a valuable resource for viral genomics, gene annotation, and virus-host interaction studies.
Main Methods:
- Nanopore sequencing was employed to generate transcriptomic data for Influenza A virus (H1N1), Zika virus, West Nile virus, Crimean-Congo hemorrhagic fever virus, Coxsackievirus B5, and Vesicular stomatitis Indiana virus.
- Raw sequencing reads underwent quality filtering (Q-score ≥ 7) during basecalling.
- High-quality reads were mapped to viral and host genomes, with read length distribution and data statistics analyzed using the ReadStat.4 Python script.
Main Results:
- High-quality nanopore sequencing data were generated for six RNA viruses and their host responses.
- The data enable detailed profiling of viral transcriptomic landscapes.
- Analysis facilitates novel gene annotations and insights into virus-host interactions.
Conclusions:
- The generated datasets are a valuable resource for comparative transcriptomic analysis of RNA viruses.
- This study supports the investigation of RNA base modifications and the comparison of various sequencing and bioinformatics approaches.
- The findings contribute to a deeper understanding of viral RNA biology and host-pathogen dynamics.

Viruses with RNA Genomes
107
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

RNA-seq
10.4K
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

Viral Mutations
32.8K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...
