Extracellular vesicles from saxitoxin-producing strains of the cyanobacterium Raphidiopsis raciborskii and investigation of their potential allelopathic effect The cyanobacterium Raphidiopsis raciborskii can exert allelopathic effects on other phytoplankton species, but the role of extracellular vesicles (EVs…

We #first provided evidence that a fraction of these toxins is released through extracellular vesicles (the vesicular fraction) β€” a mechanism that requires further investigation since it may play a key ecological role.

πŸ”Here we tested whether EVs contribute to the inhibitory effect caused by the Cyanobacteria exudate on algae, and proposed that extracellular saxitoxins released by these microorganisms challenge the conventional assumption that these toxins occur only in dissolved form in the surrounding medium.

🚨New paper alert!

I’m thrilled to share that our paper characterizing #extracellular vesicles of the toxic #cyanobacterium Raphidiopsis raciborskii has just been published on Algal Research Elsevier

🚨 In our new #preprint we investigated the #extracellularvesicles of the #cyanobacterium Raphidiopsis raciborskii, first reported #saxitoxins released into its EVs and whether they contribute to R. raciborskii #allelopathy on phytoplankton.

Distinct horizontal gene transfer potential of extracellular vesicles versus viral-like particles in marine habitats - Nature Communications Biller et al. use long-read sequencing of fractionated ocean nanoparticles, showing that extracellular vesicles and virus-like particles contain distinct pools of genetic information and thus may diff...

Our latest on the genetic content carried within different populations of DNA-containing particles in the oceans! Vesicles and viruses likely play distinct roles in microbial horizontal gene transfer networks. Grateful to all collaborators
