Emergence of histone-based chromatin complexity in Asgard archaea

Chung Hyun Cho, Colleen S. Russett, Zachary H. Harvey, N Pende, Logan H. Hodgskiss, Jérémy Cangi, Philipp Radler, Karin Hager, Miroslav Homola, Richard Imre, Gabriela Krššáková, Shun’ichi Ishii, Harsh M. Ranawat, Isabelle Anna Zink, Nevena Maslać, , Frédéric Berger

This study identifies histone-based chromatin regulation components in Asgard archaea, suggesting these features predate eukaryogenesis.

Evolutionary flexibility of ribosome biogenesis in bacteria

Kazuaki Amikura, Shun’ichi Ishii, Yoshihiro Shimizu, Shino Suzuki

The paper analyzes over 30,000 bacterial genomes to show that CPR bacteria have fewer ribosome biogenesis factors, suggesting evolutionary flexibility in ribosome assembly.
