The microbial pan-genome

TL;DR: In this article, the authors examined Mahoney Lake with a multi-proxy approach and used lipid biomarkers to understand organic matter production burial in the lake and find strong evidence of lateral transport of organic matter from shoreline microbial mats to the lake bottom sediments.

TL;DR: The most common enterohemorrhagic Escherichia coli (EHEC) serotype in North America, E. coli O157:H7 was recognized as a human pathogen in 1982 when it was isolated from 47 persons in two states who had developed bloody diarrhea after consuming hamburgers contaminated with this organism as mentioned in this paper.

TL;DR: Over 1.2 million previously unknown genes represented in these samples, including more than 782 new rhodopsin-like photoreceptors are identified, suggesting substantial oceanic microbial diversity.

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.

TL;DR: Mobile elements within genomes have driven genome evolution in diverse ways and are becoming useful tools for learning more about genome evolution and gene function.

TL;DR: The current review presents the available genomics and biological data on prophages from bacterial pathogens in an evolutionary framework to demonstrate that the chromosomes from bacteria and their viruses (bacteriophages) are coevolving.
