Characterization and phylogenetic analysis of the mitochondrial genomes of four Xanthoparmelia (Vain.) Hale lichen fungi

In this study, the complete mitochondrial genomes of four Xanthoparmelia species (X. chlorochroa, X. coreana, X. pulvinaris, and X. stenophylla) were sequenced, assembled and annotated. The four mitochondrial genomes are all composed of circular DNA molecules, with a total length ranging from 81,294 bp to 88,296 bp, containing 41–42 genes (14 protein-coding genes (PCGs), 2 rRNA genes, and 25–26 tRNA genes), the GC content is 30%–30.7% and the AT skew is positive. Phylogenetic analysis based on 14 PCGs and rRNA genes revealed that the four Xanthoparmelia species form a well-supported clade within Parmeliaceae.
