New paper out in ISME Journal. Social interactions between strains shape bacterial communities. However, their impact on community functioning is lower compared to basic strain identity features. @joskramer.bsky.social @alexfig.bsky.social @simonmarech.bsky.social
academic.oup.com/ismej/advanc...

Strain identity effects contribute more to Pseudomonas community functioning than strain interactions

Abstract. Microbial communities can shape key ecological services, but the determinants of their functioning often remain little understood. While traditio

We derive iron-siderophore interaction networks among Pseudomonas strains from sequencing data. One key insight: natural strains form dense networks, whereas pathogens are loners. With @frimanscience.bsky.social @zhiyuanli.bsky.social & Nanjing colleagues

Siderophore synthetase-receptor gene coevolution reveals habitat- and pathogen-specific bacterial iron interaction networks

Coevolving siderophore genes shape bacterial iron networks, unveiling the complexity of cheating across habitats and lifestyles.

I have abstained from social media for quite some time. Now, I make a new effort - especially for the sake of my students and postdocs who accomplish outstanding things and keep the lab going.
