TL;DR: This work reconstructed 8 complete and 789 draft genomes from bacteria representing >35 phyla and documented features that consistently distinguish these organisms from other bacteria, infer that this group, which may comprise >15% of the bacterial domain, has shared evolutionary history, and describe it as the candidate phyla radiation (CPR).

TL;DR: This article uncovered metabolic characteristics for members of these phyla, and a new lineage, PER, via cultivation-independent recovery of 49 partial to near-complete genomes from an acetate-amended aquifer.

TL;DR: The results show that both amplicon length and primer pair markedly influence estimates of richness and evenness, however, estimates of species evenness are consistent among different primer pairs targeting the same region, highlighting the importance of experimental methodology when comparing diversity estimates across communities.

TL;DR: This study sequenced DNA from complex sediment and planktonic consortia from an aquifer adjacent to the Colorado River and reconstructed the first complete genomes for Archaea using cultivation-independent methods, which dramatically expand genomic sampling of the domain Archaea and clarify taxonomic designations within a major superphylum.

TL;DR: The potential roles of Chloroflexi in sediment carbon cycling beyond organohalide respiration are expanded to include respiration of sugars, fermentation, CO2 fixation, and acetogenesis with ATP formation by substrate-level phosphorylation.
