Characterization of the complete chloroplast genome of Scutellaria amoena C. H. Wright (Lamiaceae) a medicinal plant in southwest China

摘要

Scutellaria amoena is a frequently-used medicinal plant in Southwerst China. In this study, we sequenced the complete chloroplast (cp) genome sequence of S. amoena C. H. Wright to investigate its phylogenetic relationship in the family Lamiaceae. The chloroplast genome of S. amoena was 151, 569 bp in length with 38.4% overall GC content, including a large single copy (LSC) region of 83,739 bp, a small single copy (SSC) region of 17,326 bp and a pair of inverted repeats (IRs) of 25,252 bp. The cp genome contained 112 genes, including 79 protein-coding genes, 29 tRNA genes, and 4 rRNA genes. The phylogenetic analysis indicated S. amoena was closely related to S. baicalensis that is used as original species of Scutellariae Radix.
