Prevalence and Evolutionary Implications of Genome Rearrangements in Bacteria Abstract. The genetic material of bacteria and archaea is organized into various structures and set-ups, attesting that genome architecture is dynamic in t

Genomic rearrangements occur at varying rates across Archaea and Bacteria, but are typically enriched near the ori region. While gene synteny is widely conserved, some species show highly flexible genomic layouts. #Microevo #evolution #genomics

Introgression impacts the evolution of bacteria, but species borders are rarely fuzzy - Nature Communications It is commonly thought that bacterial species borders tend to be fuzzy, due to frequent exchange of DNA. Here, Diop et al. quantify the patterns of gene flow between core genomes across 50 major bacte...

The core genomic backbone of bacteria is not necessarily resilient to gene flow! A new study shows that introgression impacts, on average, 2% of the core genes of species - www.nature.com/articles/s41... #microevo #microeco #evolution

70% of known antibiotic resistance genes (ARGs) circulate on food products, with 40% of these ARGs on mobile elements (mostly plasmids), mostly belonging to two major pathobionts (Acinetobacter and Staph spp). Important summary stats on the resistome! #MicroEvo #AMR
