Sequence analysis and genome organization of a new marafivirus from Leptochloa chinensis.
Article in Archives of virology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
High-throughput sequencing was used to identify and characterize a novel marafivirus from the weed Leptochloa chinensis, which was tentatively named "Leptochloa chinensis marafivirus" (LcMV). The complete genome of the virus consists of 6,178 base pairs, and its nucleotide sequence is 73.82% identical to that of Sorghum almum marafivirus, which is a member of the genus Marafivirus within the family Tymoviridae. The LcMV genome contains a relatively large open reading frame (ORF) encoding a single polyprotein (220.6 kDa) with five functional domains (methyltransferase, papain-like protease, helicase, RNA-dependent RNA polymerase, and coat proteins), which is a characteristic of members of this genus. Furthermore, a 16-nucleotide conserved marafibox sequence was identified at nucleotide positions 5341-5356. The coat protein of LcMV is 68.02% identical to that of Sorghum almum marafivirus. Phylogenetic analysis based on nucleotide and polyprotein sequences showed that LcMV is closely related to members of the genus Marafivirus. Our findings support the classification of LcMV as a member of a new species within this genus. This is the first report of a marafivirus infecting Leptochloa chinensis, a very important weed of rice.
