Identification and genomic characterization of a novel polymycovirus from Alternaria alternata causing watermelon leaf blight.
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 6 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
A double-stranded RNA (dsRNA) mycovirus from the phytopathogenic fungus Alternaria alternata, which causes watermelon leaf blight, was characterized. The genome of this virus has eight dsRNA segments, ranging from 1039 bp to 2398 bp. DsRNAs 1-6 each contain a single large open reading frame (ORF), while dsRNAs 7 and 8 each dsRNA contain two ORFs. The RNA-dependent RNA polymerase (RdRp) encoded by dsRNA1 and the viral methyltransferase encoded by dsRNA3 share 97.6% and 98.9% amino acid sequence identity, respectively, with the corresponding proteins of Plasmopara viticola lesion associated polymycovirus 1. The dsRNA5-encoded proline-alanine-serine-rich protein shows 48.1% sequence identity to that of Beauveria bassiana polymycovirus 3. The proteins encoded on dsRNAs 2, 4, and 8 have 99.7%, 98.2%, and 65.1% sequence identity, respectively, to the corresponding proteins of a mycovirus identified in Alternaria sp. FA0703 (AltR1). The proteins encoded by dsRNAs 6 and 7 do not match any known proteins of mycoviruses. Phylogenetic analysis of the RdRp domain showed that the virus clustered with members of the family Polymycoviridae. Based on these characteristics, the mycovirus was identified as a polymycovirus and designated as "Alternaria alternata polymycovirus 1" (AaPmV1). This is the first report of a polymycovirus associated with A. alternata.
