Characterization of the complete mitochondrial genome of Ilex pubescens

In this study, the complete mitochondrial genome of Ilex pubescens was recovered through Illumina sequencing data. This complete mitochondrial genome of I. pubescens was 517,520 bp in length and contained a sparse gene coding structure, which account for 12.6% of the whole genome. Mt genome of I. pubescens encoded 54 genes including 33 protein-coding genes, 18 tRNA genes and 3 ribosomal RNA genes. The overall GC content of I. pubescens mt genome is 45.6%. By phylogenetic analysis using whole genome-wide alignments through IQ-TREE, I. pubescens existed in a unique branch as a distinct order, which showed a relatively close relationship within Campanulids clade. This complete mitochondrial genome can be subsequently used for further evolution studies of asterids plants.
