New #ISEPpapers #preprint by @deemteam.bsky.social: Re-evaluating the eukaryotic Tree of Life with independent phylogenomic data www.biorxiv.org/content/10.6...

#Protists #Microbes #Evolution #Eukaryotes #TreeOfLife #Phylogeny #Phylogenomics #Bioinformatics #Algae

We have just published a short note on archaeal phylogeny: complex mixture models support a deep placement of Methanonatronarchaeia within Euryarchaea and indicate that three recently described groups (Halorutilales, Afararchaeaceae, and Ordosarchaeia) are actually the same.

So you are using IQ-TREE to estimate a tree for "deep time" phylogenetics using amino acid alignments. There is a lot of confusion about how to test model fit. Here are some suggestions.

Archaea Assemble!!! Archaea Power Hour returns next WEDNESDAY, March 18th at 11AM EST / 4PM CET. We will be having a special APH edition about science policy & reproducibility with the American Society for Microbiology and the protocol-sharing platform archaea.bio:

Beyond thrilled to share that our study has been published!
This project encompasses years of work, including my thesis research on Asgard archaea in the @archaeal.bsky.social lab at @utmsi.bsky.social and

Thanks Lewen!

Phylogenomic analyses indicate the archaeal superphylum DPANN originated from free-living euryarchaeal-like ancestors - Nature Microbiology Phylogenetic reconstructions with conserved protein markers from the 11 known DPANN phyla reveal their monophyletic placement within the Euryarchaeota.

Postdoc Comparative genomics and genome architecture in early-diverging fungi and their protist relatives (3-year position)

Exciting news! I'm looking for a computational biologist to join my lab at Wageningen University & Research! It's a 3-year postdoc position on Holomycota genome architecture and evolution. Spread the word! www.wur.nl/en/vacancy/p...

Congrats!

Nested parasitism in hypersaline environments: viruses and virus satellites of haloarchaea and their nanosized cellular symbionts It is increasingly recognized that hyperparasitism, whereby a parasite exploits a host which itself is a parasite, is a common phenomenon across ecosystems and domains of life. Here, to explore hyperp...

After 3 years of work, we are thrilled to submit this preprint. In collaboration with DEEM Team, we uncovered the complex interactions between haloarchaea, nanohaloarchaea, and their respective viruses and virus satellites. See🧵
