Summary
Next-generation sequencing (NGS) enables pathogen identification, but viral genome assembly requires user-friendly bioinformatics. We developed VirusTAP, a web tool for rapid and accurate viral genome sequence assembly from metagenomic data.
Area of Science:
- Virology
- Bioinformatics
- Genomics
Background:
- Next-generation sequencing (NGS) offers comprehensive pathogen identification from clinical samples.
- Obtaining complete viral genome sequences is crucial for traceability and phylogenetic analysis.
- Existing bioinformatics pipelines for viral genome assembly can be complex and time-consuming.
Purpose of the Study:
- To develop a simple and user-friendly web-based tool for viral genome assembly from NGS data.
- To improve the accuracy and speed of viral genome sequence retrieval from metagenomic reads.
- To facilitate molecular phylogenetic analyses by providing complete viral genomes.
Main Methods:
- Development of a web-based integrated NGS analysis tool named VirusTAP (virus genome-targeted assembly pipeline).
- Implementation of extensive sequence subtraction to remove host and bacterial reads.
- Application of de novo assembly algorithms for viral genome reconstruction.
- Utilizing metagenomic NGS reads as input.
Main Results:
- VirusTAP enables prompt and accurate assembly of viral genome sequences.
- The tool effectively removes non-viral reads, enhancing assembly quality.
- Successfully retrieves complete viral genomes from complex metagenomic datasets.
Conclusions:
- VirusTAP provides an efficient solution for viral genome assembly from NGS data.
- The tool simplifies the bioinformatics workflow for viral discovery and characterization.
- Facilitates enhanced traceability and phylogenetic studies of viral pathogens.

Genome Annotation and Assembly
21.5K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Size and Structure of Viral Genomes
1.0K
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...

Viruses with RNA Genomes
1.3K
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...
