The complete chloroplast genome sequence of the medicinal plant Mesona chinensis (Labiatae).

Mesona chinensis is an important traditional Chinese medicine and edible plant resource in China. In this work, we sequenced the complete chloroplast genome of M. chinensis and researched its evolution. The genome size is 152,547 bp, with 37.89% GC content, including a large single copy region (LSC) of 83,482 bp, a small single copy region (SSC) of 17,725 bp and a pair of inverted repeats region (IRs) of 25,670 bp. The complete chloroplast genome was predicted to encode 131 genes, consist of 86 protein-coding genes, 37 tRNA genes and 8 rRNA genes. Phylogenetic analysis showed that M. chinensis was closely related to other Labiatae species Ocimum tenuiflorum.
