Bacterial growth rate in populations and single cells
Nature Microbiology, Published online: 17 September 2026; doi:10.1038/s41564-026-02449-6In this Perspective, Levin and Wang give a brief history of bacterial growth rate and discuss how it is connected to nutrient availability and macromolecule synthesis, with a focus on (p)ppGpp as a central hub regulating resource allocation and, indirectly, growth rate at the single-cell level.

➡️ preprint from the lab! Bacteria have loads of antiviral defences in their mobile genetic elements (MGEs). So when MGEs move between bacteria, the defences move with them, generating a fast turnover of defences in bacteria. But what about the antiviral defence turnover in the MGEs themselves? 🤔 🧵👇
