Bacterial whole-genome resequencing involves sequencing the entire genome of a bacterium and comparing the sequencing reads to a known reference. CD Genomics is a leading custom service provider in sequencing technologies, particularly in the field of long-read sequencing. Our bacterial whole-genome resequencing service enables the analysis of multiple genomic variation types among microbial strains, providing accurate and in-depth information on bacterial genome sequences. With world-leading equipment combined with cutting-edge sequencing technology, we continue to help researchers gain new insights into bacteriology.
Whole-genome resequencing is a powerful tool to study bacterial genomes. So far, this method has helped researchers detect mutations in genetic suppressor screens, infer genome replication status, and identify base-pair substitutions, short insertions/deletions, and structural variants in genome instability studies. To perform whole-genome resequencing, Illumina sequencing has become the most straightforward and widely used approach. As the study of bacterial genetics continues, the shortcomings of this technology have become increasingly apparent. The Illumina platform has read lengths between 50-300 bp, which makes it very difficult to perform de novo assembly of the genome through repetitive genomic regions. The long-read sequencing platform overcomes the challenges related to short Illumina reads by significantly increasing read length. In addition, the ability of long-read sequencing to directly detect DNA base modifications without prior knowledge of their existence makes it an excellent tool to promote our understanding of a wide range of topics in bacteriology.

Unlocking the intricate tapestry of genetic diversity within a species is pivotal for unraveling its evolutionary journey. Pangenomes, serving as a comprehensive genetic atlas, offer profound insights into both sequence polymorphisms and structural variants (SVs) present in a species.
Navigating the genetic labyrinth of Saccharomyces cerevisiae posed formidable challenges. The species' broad spectrum of phylogenetic and ecological diversity necessitated an innovative approach to comprehensively capture its genomic essence. Overcoming complexities inherent in heterozygous diploid and polyploid isolates was essential for unearthing the true tapestry of genetic variation.
Drawing inspiration from the Yeast 1011 Genome Project, they meticulously selected a cohort of 100 Saccharomyces cerevisiae strains for hifi sequencing, yielding a treasure trove of 100 high-quality reference genomes. An additional 18 genomes were meticulously reassembled using ONT raw data, complemented by 24 publicly accessible reference genomes. This intricate amalgamation culminated in the creation of the Saccharomyces cerevisiae Reference Assembly Panel (ScRAP), a peerless reference atlas.
The ScRAP stands as a testament to the power of pangenomics in unraveling the species' genomic tapestry. Within its confines, they unearthed approximately 4,800 nonredundant SVs, each a unique brushstroke on the canvas of genetic diversity. Notable among these findings were the dynamic fluctuations in telomere length and transposable elements, unveiling previously concealed layers of genomic dynamics. Complex aneuploidies, characterized by sweeping chromosome deletions and translocations, emerged as recurrent phenomena, further enriching our understanding of genetic variation.
