Contingency, repeatability, and predictability in the evolution of a prokaryotic pangenome (2023)
Journal Article
Beavan, A., Domingo-Sananes, M. R., & McInerney, J. O. (2024). Contingency, repeatability, and predictability in the evolution of a prokaryotic pangenome. Proceedings of the National Academy of Sciences, 121(1), Article e2304934120. https://doi.org/10.1073/pnas.2304934120

Pangenomes exhibit remarkable variability in many prokaryotic species, much of which is maintained through the processes of horizontal gene transfer and gene loss. Repeated acquisitions of near-identical homologs can easily be observed across pangeno... Read More about Contingency, repeatability, and predictability in the evolution of a prokaryotic pangenome.

Evidence for Selection in the Abundant Accessory Gene Content of a Prokaryote Pangenome (2021)
Journal Article
Whelan, F. J., Hall, R. J., & McInerney, J. O. (2021). Evidence for Selection in the Abundant Accessory Gene Content of a Prokaryote Pangenome. Molecular Biology and Evolution, 38(9), 3697-3708. https://doi.org/10.1093/molbev/msab139

A pangenome is the complete set of genes (core and accessory) present in a phylogenetic clade. We hypothesize that a pangenome's accessory gene content is structured and maintained by selection. To test this hypothesis, we interrogated the genomes of... Read More about Evidence for Selection in the Abundant Accessory Gene Content of a Prokaryote Pangenome.

© 2019 by the authors. Licensee MDPI, Basel, Switzerland. The formation of new genes by combining parts of existing genes is an important evolutionary process. Remodelled genes, which we call composites, have been investigated in many species, howeve... Read More about Eukaryote genes are more likely than prokaryote genes to be composites.

Function-related replacement of bacterial siderophore pathways (2017)

© The Author(s) 2018. Bacterial genomes are rife with orphan biosynthetic gene clusters (BGCs) associated with secondary metabolism of unrealized natural product molecules. Often up to a tenth of the genome is predicted to code for the biosynthesis o... Read More about Function-related replacement of bacterial siderophore pathways.

Why prokaryotes have pangenomes (2017)
Journal Article
McInerney, J. O., McNally, A., & O'Connell, M. J. (2017). Why prokaryotes have pangenomes. Nature Microbiology, 2(4), https://doi.org/10.1038/nmicrobiol.2017.40

The existence of large amounts of within-species genome content variability is puzzling. Population genetics tells us that fitness effects of new variants—either deleterious, neutral or advantageous—combined with the long-term effective population si...

© The Author(s) 2016. The spatial distribution of microbes on our planet is famously formulated in the Baas Becking hypothesis as “everything is everywhere but the environment selects.” While this hypothesis does not strictly rule out patterns caused...

Endosymbiotic origin and differential loss of eukaryotic genes (2015)
Journal Article

Chloroplasts arose from cyanobacteria, mitochondria arose from proteobacteria. Both organelles have conserved their prokaryotic biochemistry, but their genomes are reduced, and most organelle proteins are encoded in the nucleus. Endosymbiotic theory...

Origins of major archaeal clades correspond to gene acquisitions from bacteria (2014)
Journal Article
Nelson-Sathi, S., Sousa, F. L., Roettger, M., Lozada-Chavez, N., Thiergart, T., Janssen, A., …Martin, W. F. (2015). Origins of major archaeal clades correspond to gene acquisitions from bacteria. Nature, 517(7532), 77-80. https://doi.org/10.1038/nature13805

The mechanisms that underlie the origin of major prokaryotic groups are poorly understood. In principle, the origin of both species and higher taxa among prokaryotes should entail similar mechanisms--ecological interactions with the environment paire...
