The complete chloroplast genome sequence of <i>Salvia miltiorrhiza</i>, a medicinal plant for preventing and treating vascular dementia

Abstract

<i>S. miltiorrhiza</i> is a perennial herb of the genus <i>Salvia</i> (Lamiaceae), which is an important medicinal plant for preventing and treating vascular dementia. The complete chloroplast genome sequence of <i>Salvia miltiorrhiza</i> was characterized from Illumina pair-end sequencing. The chloroplast genome of <i>S. miltiorrhiza</i> was 152,680 bp in length, containing a large single-copy region (LSC) of 84,104 bp, a small single-copy region (SSC) of 17,638 bp, and two inverted repeat (IR) regions of 25,469 bp. The overall GC content is 38.70%, while the correponding values of the LSC, SSC, and IR regions are 36.2%, 31.9%, and 43.2%, respectively. The genome contains 131 complete genes, including 86 protein-coding genes (62 protein-coding gene species), 37 tRNA genes (29 tRNA species) and 8 rRNA genes (4 rRNA species). The Neighbour-joining phylogenetic analysis showed that <i>S. miltiorrhiza</i> and <i>Salvia przewalskii</i> clustered together as sisters to other <i>Salvia</i> species.
