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.

For some three billion years, unicellular organisms ruled Earth. Then, around one billion years ago, a new chapter of life began

How did life get multicellular? Five simple organisms could have the answer
Single-celled species that often stick together in colonies have researchers rethinking the origin of animals.

We sincerely appreciate the constructive peer review and the reviewers’ thoughtful, supportive feedback, which greatly strengthened our work.
Insights into the origins of the #tubulin / #FtsZ superfamily: @syncellbiolab.bsky.social, Pananghat Gayathri et al show that two #Asgard archaeal paralogs OdinFtsZ1 and OdinFtsZ2 form distinct filamental structures, and employ different modes of membrane tethering

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!

Isolated in just 3 years! (previously, 12 years). We obtained two strains from 'Hodarchaeales', proposed to be closest to our archaeal ancestor. Our analysis suggests the ancestor was an anaerobic, syntrophic, peptidotrophic, archaeon with a simple intracellular structure and possible aerotolerance.
Eukaryotes' closest relatives are internally simple syntrophic archaea
Eukaryotes are theorized to have originated from an archaeal phylum Promethearchaeota (formerly 'Asgard' archaea)1,2. The first cultured representatives revealed valuable insight3,4 but are distantly ...

First Post! Thrilled to share our lab's first evolutionary cytoskeleton study! We uncover two distinct FtsZ paralogs in Odinarchaeota OdinFtsZ1 forms curved filaments, while OdinFtsZ2 assembles into spiral rings. A glimpse into tubulin evolution! threads👇 #Eukaryogenesis #AsgardArchaea #cytoskeleton
