Characterization of the complete chloroplast genome of shrubby sophora (<i>Sophora flavescens</i> Ait.)

Abstract

<i>Sophora flavescens</i>, with high medicinal value, is a traditional Chinese medical plant wildly distributed in China. In this study, the complete chloroplast (cp) genome of <i>Sophora flavescens</i> was determined through Illumina sequencing method. The complete chloroplast genome of <i>S. flavescens</i> was 154,378 bp in length and contained a pair of IR regions (28,876 bp) separated by a small single copy region (18,110 bp) and a large single copy region (84,516 bp). The cp genome of <i>S. flavescens</i> encoded 130 genes including 84 protein-coding genes, 37 tRNA genes and eight ribosomal RNA genes. The overall GC content of <i>S. flavescens</i> cp genome is 36.6%. By phylogenetic analysis using ML method, <i>S. flavescens</i> showed the closest relationship with <i>Sophora alopecuroides</i>.
