Complete chloroplast genome sequence of Stachys japonica (Labiatae)

Abstract

The complete chloroplast genome of Stachys japonica 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 S. japonica chloroplast genome was 38.5%. Phylogenetic analysis with several reported chloroplast genomes showed that S. japonica is closely clustered with S. sylvatica. The complete chloroplast genome of S. japonica provides new insight into Labiatae evolutionary and genomic studies.
