Glad to share our paper out today @NatureEcoEvo: “Serial innovations by Asgard archaea shaped the DNA replication machinery of the early eukaryotic ancestor”. www.nature.com/articles/s41... #microsky #archaeasky
Serial innovations by Asgard archaea shaped the DNA replication machinery of the early eukaryotic ancestor - Nature Ecology & Evolution
Phylogenetic and biochemical analyses show a diversity of components of the DNA replication machinery in different Asgard archaea that contributed to the eukaryotic DNA replication machinery.

We’ve uncovered Asgard chromatin structures formed by a Hodarchaeal histone : closed hypernucleosome conserved in archaea and an open form resembling the H3-H4 eukaryotic octasome. Fantastic work by @harshranawat.bsky.social!

So happy to have published my PhD work! What a funky phage, it was a ride. Big thanks to @beatrizbeamud.bsky.social & @jmouradesousa.bsky.social for bringing their expertise into this story. And my mentors @jmghigolab.bsky.social & @dbikard.bsky.social 💪🏼
How does the lysogenic-lytic cycle work in intestinal #bacteriophages? @sol-uble.bsky.social @dbikard.bsky.social @jmghigolab.bsky.social &co show that hankyphage produces defective viral particles & identify RepCHP as master repressor of this #phage's lytic cycle @plosbiology.org 🧪 plos.io/41Rr22S
