Taxonomically distinct diatom viruses differentially impact microbial processing of organic matter.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Phytoplankton viruses facilitate the production of dissolved organic matter (DOM) through host lysis, shaping DOM composition, and subsequent regenerative processing. We explored how DOM generated from a bloom-forming, centric diatom, infected with taxonomically distinct viruses-a single-stranded (ss) DNA and a ssRNA virus-impacted microbial processing of organic matter. DOM derived from uninfected and ssDNA virus-infected cultures supported growth in bacterial isolates and a mixed assemblage. In contrast, DOM from ssRNA virus infection did not stimulate growth, but rather induced ectoproteolytic activity, suggesting this DOM was less bioavailable. Exoprotease activity was also substantially higher in ssRNA virus-infected cellular exudates compared to ssDNA virus-infected and uninfected cultures. This suggests that DOM produced through virus-mediated host lysis does not a priori support secondary production and implicate ssRNA virus infection as a source of proteolytic activity in the water column, highlighting a multifaceted role for viruses in altering microbial utilization and remineralization length scales of organic matter in the ocean.
