Biogeography and host interactions of CPR and DPANN viruses in acid mine drainage sediments.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The CPR and DPANN superphyla are globally distributed in anoxic habitats including extreme environments. However, the biogeography and potential ecological functions of their viruses remain unexplored. Here, we recover diverse CPR/DPANN metagenomic viral genomes from 90 acid mine drainage (AMD) sediments sampled across southeast China. Our data reveal deterministic processes as the primary driver of virome assembly shaping the distinct distribution patterns of CPR and DPANN viruses. While lifestyle prediction shows higher lytic virus diversity associated with DPANN, both CPR/DPANN viruses likely use the Piggyback-the-winner (PtW) strategy to co-exist with hosts in AMD sediments, with CPR viromes exhibiting increased lysis in low host-density regimes under intensive acidity/salinity conditions. A subsequent metatranscriptomic analysis uncovers diverse functional genes encoded by CPR and DPANN viruses actively expressed in situ, potentially supplementing host metabolisms yet diverging in replication, transcription, and translation-related functions. Furthermore, partial correlation network analysis suggests that putative symbiotic hosts of the CPR/DPANN may confer protection against viral infection through enhanced antiviral defense. Our results highlight the complex interplays between viruses, DPANN and CPR organisms, and their symbiotic hosts.
