Epigenetic control of tetrapyrrole biosynthesis by m4C DNA methylation in a cyanobacterium Abstract. Epigenetic DNA modifications are pivotal in eukaryotic gene expression, but their regulatory significance in bacteria is less understood. In Syne

Cytosine N4-methylation by the DNA methyltransferase M.Ssp6803II is required for the proper expression level of protoporphyrinogen IX oxidase, HemJ. All details in our new paper in DNA Research: academic.oup.com/dnaresearch/...

Microcystin shapes the Microcystis phycosphere through community filtering and by influencing cross-feeding interactions Abstract. The cyanobacterium Microcystis causes harmful algal blooms (cyanoHABs) that pose a major threat to human health and ecosystem services, particula

We are pleased to share our new paper in which we have investigated the role of microcystin in a synthetic community of Microcystis and phycosphere bacteria.

“Bacterial-MERFISH” provides ~1000-fold volumetric expansion of individual cells, charts gene expression in hundreds of thousands of cells, deciphering bacterial single-cell heterogeneity, intracellular transcriptome organization, and bacterial adaptation to µm-scale niches in vivo

Does mRNA targeting explain gene retention in chloroplasts? During their evolution from cyanobacteria, plastids have relinquished most of their genes to the host cell nucleus, but have retained a core set of ge…

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.

Horizontal gene transfer of the functional archaellum machinery to Bacteria Motility in Archaea is driven by a nanomachinery called the archaellum. So far, archaella have been exclusively described for the archaeal domain; however, a recent study reported the presence of arch...

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...
