A family-level phylogeny of liverworts (Marchantiophyta): new insights from mitochondrial sequences

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. Complete_mitogenomes.zip contains 23 newly assembled complete mitochondrial genomes from liverwort plants.Figure1.zip contains the alignment matrix and phylogenetic trees for 63 complete liverwort mitogenomes.Figure3.zip contains the alignment matrix and phylogenetic trees for 183 complete liverwort mitogenomes.
