One is not enough: On the effects of reference genome for the mapping and subsequent analyses of short-reads.
2020
Mapping of high-throughput sequencing (HTS) reads to a single arbitrary reference genome is a frequently used approach in microbial genomics. However, the choice of a reference may represent a source of errors that may affect subsequent analyses such as the detection of single nucleotide polymorphisms (SNPs) and phylogenetic inference. In this work, we evaluated the effect of reference choice on short-read sequence data from five clinically and epidemiologically relevant bacteria (Klebsiella pneumoniae, Legionella pneumophila, Neisseria gonorrhoeae, Pseudomonas aeruginosa and Serratia marcescens). Publicly available whole-genome assemblies encompassing the genomic diversity of these species…
Population Genomics of Human Viruses
2018
Viruses, and a few RNA viruses in particular, represent one of the greatest threats for human health. High mutation rates, large population sizes, and short generation times contribute to their typically fast evolutionary rates. However, many additional processes operate on their genomes, often in opposite directions, driving their evolution and allowing them to adapt to diverse host populations and antiviral drugs. Until recently, the high levels of genetic variation of most viruses have been explored only at a few genes or genome regions. The recent advent and increasing affordability of next-generation sequencing techniques have allowed obtaining complete genome sequences of large number…
