Active but not passive passengers: Persistent-propagative plant viruses manipulate insect vectors for efficient transmission.
Review in PLoS pathogens, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Most plant viruses rely on insect vectors for transmission. In general, nonviruliferous vectors acquire viruses from infected plants, whereas viruliferous vectors subsequently move to uninfected plants for virus inoculation. However, they are not merely passive passengers within their vector. Persistent-propagative plant viruses, which invade and replicate in insect vectors, can actively and directly reshape their physiology, morphology, and feeding behavior to facilitate efficient transmission. Recent studies have uncovered both indirect plant-mediated mechanisms and direct vector-targeted mechanisms, including modulation of neural signaling, olfactory systems, wing development, and feeding activity. Here, we summarize current understanding of how persistent-propagative plant viruses integrate indirect plant-mediated effects with direct manipulation of insect vectors. We further discuss the ecological implications of these virus-plant-vector interactions, highlight major bottlenecks in virus-insect interaction research, and emerging technological advances that may facilitate future mechanistic studies and support innovative strategies for controlling vector-borne plant viral diseases.
