Raw sequencing data of liverwort mitochondrial genomes

Liverworts, with approximately 7,300 species worldwide, exhibit remarkable morphological diversity, in terms of growth form, ontogeny and architecture. Their mitochondrial genome exhibits lower average substitution rates compared to their nuclear and plastid genomes, and shows less structural variation, suggesting its suitability for inferring relationships at higher taxonomic levels. In this study, we substantially expanded mitochondrial sampling in liverworts by adding complete mitochondrial gene sets from 97 species across 25 families, thereby increasing family-level coverage to 71%. Among these, we newly assembled 23 complete mitochondrial genomes. README.txt contains the correspondence between file names and species.

苔类植物（Liverworts）全球约有7300个物种，在生长型、个体发育（ontogeny）与结构构型方面展现出显著的形态多样性。与核基因组和质体基因组相比，其线粒体基因组的平均替换率更低，结构变异也更少，这表明其适用于推断高级分类阶元间的系统发育关系。本研究通过新增来自25个科的97个物种的完整线粒体基因集，大幅拓展了苔类植物的线粒体基因组采样范围，将科级覆盖度提升至71%。其中，本研究新组装了23个完整的线粒体基因组。README.txt文件中包含了文件名与物种的对应关系。
