Abstract: Candidate phyla radiation (CPR) constitutes a substantial fraction of bacterial diversity, yet their survival strategies and biogeochemical roles in brackish-saline groundwater remain unknown. By reconstructing 399 CPR metagenome-assembled genomes (MAGs) and 2007 non-CPR MAGs, we… read more here.

DOI: 10.1101/2022.01.07.475337
Abstract: The Candidate Phyla Radiation (CPR) is a large bacterial group consisting mainly of uncultured lineages. They have small cells and small genomes, and often lack ribosomal proteins L1, L9, and/or L30, which are basically ubiquitous… read more here.

DOI: 10.1128/msystems.01488-21
Abstract: Candidate phylum radiation (CPR) bacteria comprise a poorly understood phylum that is estimated to encompass ∼26% of all diversity of domain bacteria. Among CPR bacteria, the Saccharibacteria lineage (TM7) is of particular interest, as it… read more here.

DOI: 10.1186/s40168-023-01704-w
Abstract: Background Biofilms in sulfide-rich springs present intricate microbial communities that play pivotal roles in biogeochemical cycling. We studied chemoautotrophically based biofilms that host diverse CPR bacteria and grow in sulfide-rich springs to investigate microbial controls… read more here.
