Viral condensates formed by Pea enation mosaic virus 2 sequester ribosomal components and suppress translation.
Article in Virology, 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
Viral proteins with intrinsic disorder, such as the p26 movement protein from Pea enation mosaic virus 2 (PEMV2), can phase separate and form condensates that aid specific stages of virus replication. However, little is known about the impact of viral condensate formation on essential cellular processes, like translation. In this study, we performed mass spectrometry on affinity-purified p26 condensates and found an enrichment of RNA-binding proteins involved in translation and ribosome biogenesis. Puromycin assays and polysome profiling show that ectopic p26 expression suppresses ribosome assembly and translation in Nicotiana benthamiana, mirroring defects in late-stage PEMV2 infection. Despite interactions with the 2'-O-methyltransferase fibrillarin, p26 does not inhibit translation by altering rRNA methylation but instead binds directly to rRNAs and decreases their solubility. Disruption of ribosome assembly and translation by p26 during late PEMV2 infection may promote stages of the virus replication cycle that are incompatible with translation, including systemic movement.
