The microbial pan-genome
1.2K
TL;DR: A decade after the beginning of the genomic era, the question of how genomics can describe a bacterial species has not been fully addressed and the pan-genome, which is composed of a "core genome" containing genes present in all strains, and a "dispensable genome", might be orders of magnitude larger than any single genome.

Massive gene presence/absence variation in the mussel genome as an adaptive strategy: first evidence of a pan-genome in Metazoa

Naranjo-Ortiz,Maria Murgarella,Pablo Balseiro,André Corvelo,Leonor Frias,Marta Gut,Toni Gabaldón,Alberto Pallavicini,Carlos Canchaya,Beatriz Novoa,Tyler Alioto,David Posada,Antonio Figueras +19 more
TL;DR: The first evidence of a pan-genome in the animal kingdom is reported, revealing that 25% of the genes of the Mediterranean mussel are subject to PAV, and it is shown that this unique feature might have an adaptive value, due to the involvement of dispensable genes in functions related with defense and survival.
Pan-Genome Analysis of Campylobacter: Insights on the Genomic Diversity and Virulence Profile
TL;DR: The pan-genome of 39 Campylobacter species was constructed using 39 representative genomes, elucidating their genetic diversity, evolutionary characteristics, and virulence and resistance profiles and highlighted the basic conserved functionality and specificity of pathogenicity that are crucial to infection.

Comparative genomics reveals broad genetic diversity, extensive recombination and nascent ecological adaptation in Micrococcus luteus.
TL;DR: In this article, comparative genomics, phylogenomics, and genome-wide association studies were used to investigate the genomic diversity, evolutionary history, and the potential ecological differentiation of the species.

TL;DR: A majority of the bacterial sequences corresponded to uncultivated species and novel microorganisms, and significant intersubject variability and differences between stool and mucosa community composition were discovered.

TL;DR: The genomic sequence of six strains representing the five major disease-causing serotypes of Streptococcus agalactiae, the main cause of neonatal infection in humans, was generated and Mathematical extrapolation of the data suggests that the gene reservoir available for inclusion in the S. agalactic pan-genome is vast and that unique genes will continue to be identified even after sequencing hundreds of genomes.
