Assembly and analysis of the complete mitochondrial genome of Leonurus japonicus (Lamiaceae).
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Leonurus japonicus Houtt. (L. japonicus), as an important plant resource with both ornamental and medicinal value, has now spread worldwide and is widely studied. Currently, its chromosomal genome and chloroplast genome (cpDNA) have been reported, but the mitochondrial genome (mtDNA) has not yet been explored. In this study, we extracted DNA from fresh leaves of L. japonicus and performed sequencing and assembly of its mtDNA using both second-generation and third-generation sequencing technologies. The complete mtDNA of L. japonicus is 382,905 bp in length, with a GC content of 45.13%. This genome includes 15 tRNA genes, 32 protein-coding genes (PCGs), and 4 rRNA genes. In this mtDNA genome, we predicted a total of 480 RNA editing sites among the 32 PCGs. Subsequently, we conducted analyses on repetitive sequences, organelle genome sequence migration, and Relative Synonymous Codon Usage (RSCU). There are 28 homologous sequence fragments between the mtDNA and cpDNA of L. japonicus, which are related to the migration of 10 mtDNA genes. The RSCU analysis predicted 28 high-frequency codons, most of which prefer to end with A/U. Selection pressure analysis indicated that the Ka/Ks ratio for the majority of PCGs is less than 1, suggesting they are highly conserved during evolutionary processes. Phylogenetic results from 24 species indicate that the genera Leonurus and Scutellaria within the Lamiaceae family have the closest relationships. In summary, we have successfully assembled the complete mtDNA of L. japonicus by integrating second-generation and third-generation sequencing data for the first time. Subsequent multi-faceted analyses have allowed us to gain deeper insights into the numerous features of this genome, providing important reference data for the molecular genetics, dynamic evolution, and species identification of this plant. This work promotes the conservation and development of this important resource of medicinal and edible plants.
