Photosynthetic bacteria helped shape Planet Earth. Among them cyanobacteria—microbes that produced the oxygen in Earth’s atmosphere & made complex life possible. They have captivated scientists for decades by offering insights into how life evolved from single cells into multicellular organisms.

Now out in its final form! www.science.org/doi/10.1126/...

I am (months) late, but you HAVE TO read @huepfkiesel.bsky.social (there is an update version). How can ParM "turned MreB” in cyanos? shorturl.at/JXMjy This will become a classic. Such a clear example of homology =/= function. We need more studies to collect larger sample sizes to test it.

Happy to share a new preprint from the lab: Marko became interested in whether the disordered linker of FtsZ might influence how the protein organizes into the Z-ring. And this led to some surprising findings! Preprint: www.biorxiv.org/content/10.1...

Great work by Benjamin Springstein @huepfkiesel.bsky.social and the lab of Martin Loose @nartimsoole.bsky.social. Really stunning finding of the evolutionary repurposing of a DNA segregation machinery into a cell shape cytoskeletal system in cyanobacteria. Make sure to have a look!

One of the most exciting discoveries from our lab so far is now online as a preprint! Read a story on how the ParMR and Min systems started to collaborate to create the CorMR cytoskeleton, which now controls cell shape in multicellular cyanobacteria: www.biorxiv.org/content/10.1...
