The EMBO workshop (March 2027) on marine microbial chemicals communication is open for abstract submission and registration (deadline 20th Oct 2026). The inaugural meeting in 2025 was fantastic and there are already some great speakers lined up, highly recommended. meetings.embo.org/event/27-mar...

Microbes that have the greatest genomic potential for secondary metabolism tend to be multicellular. Here, we show that signatures of ancestral BGC expansions within 3 bacterial phyla and 2 fungal lineages coincide with origins of complex multicellularity [1/12] 🧵 www.nature.com/articles/s41...

Complex multicellularity is linked with expanded specialized metabolite production in microorganisms - Nature Microbiology

The evolutionary emergence of complex multicellularity in bacteria and fungi, such as the ability for mycelial growth, is strongly associated with increased genomic carriage of biosynthetic machinery ...

Our study on Bacteroides iron piracy is now out in @pnas.org. We show how surface-exposed lipoproteins bind xenosiderophores with different iron-chelating chemistries and propose a mechanism for xenosiderophore import across the outer membrane. Lots of structures (mostly X-ray this time)!
