Latest from ours: www.cell.com/cell-reports... This is two stories in one: a case study/cautionary tale on developing genetic tools in new organisms, and the first hint at a gene regulatory network for choanoflagellate multicellular development (which turn out to involve a Hippo/YAP/ECM loop!) A 🧵

New preprint! Ever wondered why only a fraction of genomes encode CRISPR immunity? 🧬 🦠 Turns out CRISPR is rarely beneficial against virulent phages, being most beneficial against those for which resistance mutations are rare! An epic effort by Rosanna Wright www.biorxiv.org/content/10.1...

BEHOLD! One of Earth's greatest lineages of life: the lil wiggle arm guys, Meteora. These single-celled critters, originally found in deep-sea sediments, are SO DIFFERENT from other lifeforms on Earth that they're likely in their own kingdom (as in, the Animal Kingdom, the Plant Kingdom etc). 🧪🌿

Just out - The first global ocean 3-Domain microbial survey where all organisms can be directly compared quantitatively. Unfractionated and amplified from just 2 primers (vetted with mock communities and metagenomics), so all with the same denominator. www.biorxiv.org/content/10.1...

We did it! We caught Starship #transposons moving between #fungal species in the lab, including between species separated by ~100my. We think Starships are a mediator of HGT in fungi, akin to conjugative elements in bacteria. Check out the preprint. www.biorxiv.org/content/10.1...

OK, from now on, I'll try to avoid using "early-branching" or "early-diverging" (on "lower" and "basal" I gave up long before) 🙂 Use their names: there are no basal, lower, or early diverging fungi www.tandfonline.com/doi/full/10....
