The visualization of two bacterial genomes, of 50 and 52kb, representing independent instances of extreme genomic reduction in ancient heritable endosymbionts of planthoppers.

Our new paper in @natcomms.nature.com is now online-early!

We describe independent evolution of bacterial genomes of only ~50–52 kb β€” the smallest known outside cellular organelles β€” revealing striking convergence toward minimal gene sets.

The disputed identity of Pseudomonas putida KT2440: when taxonomists rename your favorite microbe | mBio Names matter; they are not mere labels. They operate as anchors of memory, social coordinates, and references of collective identity. When a name becomes established through long-term use and broad ad...

Why rename Pseudomonas putida KT2440 to P. alloputida🦠?
This is an excellent example of why taxonomic changes require caution. We shouldn't blindly follow rules while ignoring decades of established practice.
