Complete chloroplast genome sequence of Stachys japonica (Labiatae)

The complete chloroplast genome of <i>Stachys japonica</i> was reconstructed by reference-based assembly using Illumina paired-end data. The assembled plastome is 150,599 base pairs (bp) in length, including a pair of inverted repeat regions (IRs) of 25,654 bp each, a large single-copy region (LSC) of 81,701 bp and a small single-copy region (SSC) of 17,590 bp. A total of 131 genes were predicted from the chloroplast genome, including 86 protein coding genes, 37 tRNA genes and 8 rRNA genes. The overall GC content of <i>S. japonica</i> chloroplast genome was 38.5%. Phylogenetic analysis with several reported chloroplast genomes showed that <i>S. japonica</i> is closely clustered with <i>S. sylvatica</i>. The complete chloroplast genome of <i>S. japonica</i> provides new insight into Labiatae evolutionary and genomic studies.
