Summary
QuRe software reconstructs viral quasispecies from long-read next-generation sequencing data. It accurately identifies all viral variants and their prevalence, overcoming challenges in sequencing complex pathogen populations.
Area of Science:
- Virology
- Bioinformatics
- Genomics
Background:
- Next-generation sequencing (NGS) enables deep characterization of pathogen populations.
- Reconstructing complex viral populations, especially across large genomic regions, remains a challenge.
Purpose of the Study:
- To develop a computational tool for accurate viral quasispecies reconstruction using long-read NGS data.
- To address the limitations of existing methods in analyzing highly variable viral populations.
Main Methods:
- QuRe software aligns sequence fragments to a reference genome.
- It divides the genome into windows, reconstructing viral variants and their prevalence using a heuristic algorithm.
- Includes Poisson error correction and probabilistic clustering.
Main Results:
- QuRe enables the reconstruction of all individual sequences within a viral quasispecies.
- The software captures minority variants with high resolution.
- It effectively analyzes long-read NGS data for viral population studies.
Conclusions:
- QuRe is an effective tool for viral quasispecies reconstruction from long-read NGS data.
- The software enhances the characterization of highly variable pathogens.
- It provides a robust framework for analyzing complex viral populations.

22.3K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

02:54Evolutionary Relationships through Genome Comparisons
5.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

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.
