A mycovirus-encoded homologue of plant viral movement proteins is not functional in movement complementation assays in plants.

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
Valsa mali negative strand RNA virus 1 (VmNSRV1), a fungal virus infecting Valsa mali and belonging to the Phenuiviridae family, was recently shown to be capable of naturally infecting plants. Its RNA2 encodes a homologue of a plant virus movement protein (MP) that can complement MP-deficient virus vectors and localizes to plasmodesmata, allowing natural cross-kingdom infection. To determine whether this property is a common feature among mycoviruses possessing distant MP homologues or an isolate-specific trait, we investigated Trichoderma gamsii cogu-like virus 1 (TgClV1), a Phenuiviridae member in the Bocivirus genus detected in Trichoderma gamsii. Structural analysis guided by AlphaFold confirmed that the RNA2-encoded open reading frame (ORF) contains a conserved seven beta-strand module characteristic of the 30 kDa MP superfamily, making it a putative MP-like protein (MP-L). To assess its functional role, we tested whether TgClV1's putative MP (TgCl-MPl) could complement movement-deficient plant viruses, employing tomato apex necrosis virus (ToANV), alfalfa mosaic virus (AMV), and potato virus X (PVX) MP-deficient vectors. While tobacco mosaic virus-MP successfully complemented cell-to-cell movement in trans in all these systems, TgCl-MPl did not. Additionally, localization studies of TgClV1-MPl-GFP fusions revealed that, unlike TMV-MP and VmNSRV1-MP, TgClV1-MPl did not specifically target plasmodesmata, a key characteristic of functional viral MPs. Finally, direct inoculation of Nicotiana benthamiana-either via mechanical application of purified TgClV1 or via natural inoculation through TgClV1-infected Trichoderma gamsii associated with plant roots-failed to establish infection. In conclusion, our findings do not support the hypothesis that TgClV1-MPl functions as a plant virus movement protein. The evolutionary implications of this observation are discussed.
