Next-generation sequencing reveals the mitogenomic heteroplasmy in the topmouth culter (Culter alburnus Basilewsky, 1855).
Article in Molecular biology reports, 2022. 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
backgroundThe mitogenomic heteroplasmy is the presence of multiple haplotypes in the mitochondria, which could cause genetic diseases and is also associated with many critical biological functions. The topmouth culter (Culter alburnus Basilewsky, 1855) is one of the most important freshwater fish in the family of Cyprinidae in China. At present, there are no reports on the topmouth culter's mtDNA heteroplasmy and the existence of which is not known. METHODS AND
resultsThis study aimed to analyze the mitogenomic heteroplasmy in the topmouth culter by the next-generation sequencing of the fins' total DNA. The results confirmed the existence of the heteroplasmy and indicated the presence of the extensive heteroplasmy in the topmouth culter's mitogenome. There were 38 heteroplasmic variations in the protein-coding genes from the three specimens, with 33 non-synonymous substitutions accounting for 86.84% and five synonymous substitutions accounting for 13.16%. Among them, the ND6 had the most heteroplasmic variations but only one synonymous substitution. After removing the putative nuclear mitochondrial DNA fragments, the ratio of primary haplotype in the three specimens was 43.89%, 74.72%, and 32.76%, respectively. The three specimens contained 21, 7, and 21 haplotypes of the mitogenomes, respectively. Due to the extensive heteroplasmy, we reconstructed the phylogenetic tree of the topmouth culter using the RY-coding method, which improved the performance of the phylogenetic tree to some extent.
conclusionsThis study reported the mitogenomic heteroplasmy in the topmouth culter and enhanced the knowledge regarding the mitogenomic heteroplasmy in phylogenetic studies. As the topmouth culter is a commercial species, the mitogenomic heteroplasmy is crucial for the fisheries management of the topmouth culter.
