🚨 New preprint with @annadewar.bsky.social 🚨 Do plasmids “ameliorate” towards their hosts? Maybe… We show that the classic plasmid-host GC correlation is confounded by population structure, and argue that plasmid mobility shapes the opportunity for host-associated compositional evolution.

doi.orgMobility shapes plasmid GC content evolutionPlasmids are frequently AT-rich relative to their bacterial hosts. Despite this tendency towards lower GC content, plasmid and host chromosome GC content are positively correlated across diverse collections of plasmid-host pairs. However, the evolutionary processes underlying this pattern remain unclear. The classic model of amelioration predicts that horizontally acquired DNA gradually converges on host nucleotide composition. However, because plasmids can repeatedly transfer between bacterial hosts, the opportunity for such host-associated evolution may depend on their transmission dynamics. Using 50,936 plasmid-host pairs from a public sequence database, we found that the apparent global correlation between plasmid and host chromosome GC content was largely driven by differences between bacterial species rather than within species. We therefore accounted for plasmid and host population structure when testing how plasmid mobility shaped host-associated compositional evolution. We compared two contrasting regimes: a population of 3,682 Enterobacterales plasmids distributed across diverse host backgrounds, and six long-term host-associated plasmids from a Rhizobium leguminosarum lineage with INSeq-determined gene essentiality data. In the Enterobacterales population, GC content variation was overwhelmingly explained by plasmid lineage rather than host phylogeny, and conjugative plasmids showed greater similarity to their host chromosomes than mobilisable or non-mobilisable plasmids. In the Rhizobium leguminosarum plasmids, synonymous-site composition was more similar to the host chromosome among genes required across multiple host life stages. Together, these results support a model in which plasmid mobility influences the opportunity for host-associated evolutionary processes to alter nucleotide composition. ### Competing Interest Statement The authors have declared no competing interest.

¿Un ventilador y luz violeta contra los mosquitos del verano? Sí. Esta trampa casera une biología y física: la luz UV atrae a los insectos al simular su entorno de desove y, al acercarse, el flujo del ventilador vence sus alas. El embudo los absorbe hacia la red, donde mueren por deshidratación.

Maquetas en simuladores sísmicos universitarios demuestran que fallar en entornos controlados es la mejor pedagogía. Siguiendo lecciones ancestrales como los muros incas, la flexibilidad supera a la rigidez. Reducir la masa y disipar energía evita la resonancia: los sistemas flexibles perduran.

This paper started as an idea @albertomarina.bsky.social had many years ago… which of course means he was right all along 😄. Some of us just needed a few years (and a lot of experiments) to catch up. Grateful (and slightly humbled) to be part of this. Thanks Alberto! www.cell.com/cell/fulltex...

3. Comprehensive resistome monitoring is possible using targeted metagenomic tools like ResCap (PMID: 29335005), which simultaneously detect antibiotic, and also metal and biocide resistance genes, often missed in most metagenomic surveys.

In summary, Why matters?: • No microbiome is truly “pristine” • Environmental factors (like Hg pollution) are relevant selective pressures • Resistance can spread fast even in low-impact communities • Definition of "backbone" and "baseline" resistomes are key to interpret AMR

1. Despite limited Ab exposure, the Wayampi gut microbiome harbors a robust "background" resistome of ACQUIRED resistance genes (antibiotic, metal, biocide) shared with Westerns=AMR is an ancient and conserved feature rather than solely a by-product of human activities.

2. Differences in gene distributions reflect ecological and taxonomic variation in microbiome structure. Rapid emergence of clinically relevant ARGs after healthcare or Ab exposure highlights the resistome as a “robust-yet-fragile” ecogenetic system, susceptible to disruption

A federal judge on Wednesday ordered federal agents to stop detaining and deporting refugees in Minnesota who were lawfully admitted to the U.S., granting a temporary restraining order, which halts for now the Trump administration’s operation. The administration is likely to appeal the ruling.
