Methanotrophic Methanoperedens archaea host diverse and interacting extrachromosomal elements

L.-D. Shi, J. West-Roberts, M. C. Schoelmerich, P. I. Penev, L. Chen, Y. Amano, S. Lei, R. Sachdeva, J. F. Banfield

The paper identifies and characterizes diverse extrachromosomal elements in Methanoperedens archaea, including mini-Borgs and viruses, and shows their genetic exchange and potential impact on archaeal activity.

Rare Ribosomal RNA Sequences from Archaea Stabilize the Bacterial Ribosome

A. J. Nissley, P. I. Penev, Z. L. Watson, J. Banfield, J. H. Cate

This study identifies sequence variations in archaeal ribosomes that stabilize the ribosome at high temperatures and creates a stable mutant bacterial ribosome for engineering.

Supersized ribosomal RNA expansion segments in Asgard archaea

P. I. Penev, S. Fakhretaha-Aval, V. J. Patel, J. J. Cannone, R. R. Gutell, A. S. Petrov, L. D. Williams, J. B. Glass

The paper identifies supersized rRNA expansion segments in Asgard archaea, suggesting they may represent an intermediate step in the evolution of eukaryotic ribosomal complexity.
