What are pan and core genomes?
The pangenome is the entire gene set of all strains of a species. The core genome represents the genes present in all strains of a species.
What is bacterial core genome?
The bacterial core genes are defined as single-copy, homologous genes that are present in most of the known bacterial species. There have been several studies describing such a gene set, but the number of species considered was rather small.
Do humans have a Pangenome?
In animals, the human pangenome is being studied. In 2010 a study estimated that a complete human pan-genome would contain ∼19–40 Megabases of novel sequence not present in the extant reference genome. In 2021 the Human Pangenome consortium has the goal to acknowledge the human genome diversity.
What is core genome alignment?
Core-genome alignment is a subset of whole-genome alignment, focused on identifying the set of orthologous sequence conserved in all aligned genomes. Thus, core-genome SNP typing is currently the standard method for reconstructing large phylogenies of closely related microbes [45].
What is Pan gene?
The pan-genome represents the entire set of genes within a species, consisting of a core genome — containing sequences shared between all individuals of the species — and the ‘dispensable’ genome. For example, many agronomically important genes in plant species are most often found in the dispensable genome.
Why is it important to sequence bacterial genomes?
Generating rapid and accurate microbial genome sequence information is critical for detecting low frequency mutations, finding key deletions and insertions, and discovering other genetic changes among microbial strains.
What is Pangenomic analysis?
The pan-genome encompasses the entire repertoire of genes accessible to a studied phylogenetic clade or a given species, which is divided into the core genome (genes shared by all strains), dispensable genes (genes shared only by a subset of the strains), and strain-specific (unique) genes.
