Why did chloroplasts retain some genes from their free-living ancestors rather than transferring all of them to the nucleus following endosymbiosis? We suggest that mRNA targeting might play a role. www.sciencedirect.com/science/arti...

Would you expect that Bacteria use an archaellum for swimming? We didn't, but we found that some Chloroflexota do! Find the story here: www.biorxiv.org/content/10.1... A little thread below 1/n

Multicellularity is a key feature of complex life, but how to study multicellularity in bacteria and at the single cell level? Use advanced microscopy, MS imaging, flow cytometry, spatial and single-cell transcriptomics, advanced microfluidics and more. See here: journals.asm.org/doi/10.1128/...

Not all bacteria, even of a single species, are created equal. Nor are they always unicellular. Some cyanobacteria develop heterocysts and fix nitrogen. GradR/R-DeeP analysis identified new RNA-binding proteins. Some were previously known for other functions. Others were completely uncharacterized.

The secrets of RNase P. This endoribonuclease is ubiquitous, but only in bacteria it is a ribozyme. We have characterized Ssr1238, a YlxR/DUF448 family protein to interact with the RNase P RNA in cyanobacteria. Details in our new paper: www.tandfonline.com/doi/full/10....

The "5th base": Bacteriophages that infect cyanobacteria, also called cyanophages, are full of surprises. In the genome of cyanophage S-2L, adenine (A) is completely replaced by diaminopurine (Z). www.science.org/doi/10.1126/...

Congratulations to Luisa for her excellent Ph.D. defense on "Unravelling the RNA Binding Proteome of Synechocystis sp. PCC6803"! Lots of new insight into the RNA biology of cyanobacteria. And 1 paper out, 1 in press, 2 more coming.

This is so freaking cool!! Heterotrophs sense metabolites from phage-infected Syns BEFORE they have lysed and rush to the scene to wait for the burst of delicious nutrients when the cells lyse. Microbial version of vultures circling above a sick animal in the desert.
