New online! Predation in microbial communities: gradients of nutritive killing

Predation in microbial communities: gradients of nutritive killing

Nature Reviews Microbiology, Published online: 08 May 2026; doi:10.1038/s41579-026-01299-7In this Review, Vasse and Velicer explore the phylogenetic and functional diversity of predators of microorganisms, conceptualizing the forms of microbial predation along gradients, including gradients of evolutionary adaptedness for predation and privatization of prey-derived nutrients.

Fresh out of the lab! Our new preprint is now up on BioRxiv, exploring how the beneficial bacterium Pseudomonas putida controls its T6SS nanoweapon. It turns out the Gac/Rsm pathway acts as a strict molecular brake on the system. 👇 (1/4) Read the full preprint here: doi.org/10.64898/202...

New preprint! We show that the bacterial predator B. bacteriovorus deploys a unipolar Tad nanomachine for irreversible attachment to prey and invasion. @coralietesseur.bsky.social used CRISPRi+microfluidics to overcome barriers associated with essential systems in an obligate predatory lifestyle 🦠

So excited to share our new preprint! 🎉🤩 Check it out to discover how we investigated the role and spatiotemporal dynamics of an essential Tad nanomachine during the lifecycle of our favorite bacterial predator, B.bacteriovorus 🦠 Many thanks to everyone who made this work possible!
