Characterization of a novel mitovirus isolated from the phytopathogenic fungus Fusarium pseudograminearum.
Article in Archives of virology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Mycoviruses are widespread in all major groups of plant-pathogenic fungi. So far, only one mycovirus has been reported to be associated with Fusarium pseudograminearum, the causal agent of Fusarium crown rot of wheat. In this study, a double-stranded RNA (dsRNA) segment was isolated from F. pseudograminearum strain JW2-1, and the sequence of its full-length cDNA (3077 nucleotides) was determined. Sequence analysis using the fungal mitochondrial genetic code (UGA coding for tryptophan) indicated that a single large open reading frame (ORF) is present on the positive strand of this dsRNA segment. The ORF encodes a putative RNA-dependent RNA polymerase (RdRp) of 748 amino acids (aa) with a molecular mass of 83.46 kDa. BLASTp analysis revealed that its aa sequence was 28.49-44.03% identical to those of viruses of the family Mitoviridae, with the most similarity to the corresponding RdRp sequences of Ophiostoma mitovirus 1c (44.03% identity) and Ophiostoma mitovirus 1b (40.33% identity). Phylogenetic analysis showed that this mycovirus, designated as "Fusarium pseudograminearum mitovirus 1" (FpgMV1), should be classified as a member of a new species in the earlier proposed genus "Duamitovirus" within the family Mitoviridae. To our best of our knowledge, this is the first report of a mitovirus infecting F. pseudograminearum.
