Comparative analysis of mitochondrial genomes in lycoperdaceae fungi reveals intron dynamics and phylogenetic relationships.
Article in BMC genomics, 2025. 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
backgroundThe fungi of the Lycoperdaceae family are characterized by their nearly spherical fruiting bodies and possess pharmacological, economic, and ecological values. As a group of highly valuable fungi, the classification of species within the Lycoperdaceae family continues to be a subject of debate. Mitochondrial genomes typically harbor considerable number of genes and genetic elements that offer a wealth of genetic information, making them widely utilized in phylogenetic studies of eukaryotes. However, mitochondrial genome data for the Lycoperdaceae family is insufficient, and investigating its structure offers valuable insights into the evolutionary relationships between puffball fungi and other Agaricales taxa.
resultsIn this study, we sequenced and compared the complete mitogenomes of four species of Lycoperdon and Calvatia for the first time. Comparative analysis indicated that introns and open reading frames (ORFs) influence mitochondrial genome size variation among the four species. The gene lengths and nucleotide compositions varied across the species, and synteny analysis suggested potential gene loss during Lycoperdaceae evolution. Phylogenetic relationships of 50 Agaricales and 16 Boletales species were reconstructed based on a concatenated mitochondrial gene dataset. The results elucidated the taxonomic placements of four Lycoperdaceae species within the Agaricales, confirming the monophyly of Lycoperdaceae and its nested position within Agaricaceae. With the expansion of the phylogenetic tree, the number of introns gradually decreased across the Boletales. Additionally, significant inversion and translocation events were observed in the tRNA genes of Lycoperdon pratense.
conclusionThis study represents the first assembly of complete mitogenomes for four species within the Lycoperdaceae family, laying the foundation for subsequent phylogenetic research based on fungal mitochondrial gene dataset. Comparative analysis revealed the contribution of gene composition and introns to the mitochondrial genome size. Their mitochondrial genomes underwent frequent intron loss or gain events and potential intron transfer in evolution.
