Characterization of the complete chloroplast genome sequence of Isodon japonicus (N. Burman) H. Hara (Lamiaceae).

ABSTRACT: Isodon japonicus (N. Burman) H. Hara (family: Lamiaceae), is a traditional herbal plant from Henan Province, China. In this study, we sequenced the complete chloroplast genome of I. japonicus sampled from the Funiu Mountains, Henan Province, China. The total length of the chloroplast genome is 152,298 bp, and has a typical quadripartite structure, including a large single-copy region (LSC) of 83,184 bp, a small single-copy region (SSC) of 17,806 bp and a pair of inverted repeats of 25,654 bp. The chloroplast genome of I. japonicus consists of 133 genes, including 88 protein-coding genes, eight rRNA genes, and 37 tRNA genes. There are 34 tandem repeats and 50 simple sequence repeats (SSRs) in the chloroplast genome. The total guanine-cytosine (GC) content of the whole chloroplast genome is 37.6%. Phylogenetic analysis indicated that I. japonicus forms a clade with six other Isodon species and is closely associated with I. rubescens.
