Characterization of the complete mitochondrial genome of shrubby sophora (Sophora flavescens Ait.)

Abstract

Sequencing the Sophora flavescens mitochondrial genome is important for elucidating the evolutionary characteristics of traditional Chinese medical plants. In this study, the complete mitochondrial (mt) genome of S. flavescens was sequenced through Illumina sequencing method, and the mitochondrial genome map was constructed after de novo assembly and annotation. The results showed that the 494,369 bp S. flavescens mitochondrial genome has a total of 78 genes, including 53 protein-coding genes, three rRNA genes, and 23 tRNA genes. The overall GC content of this mitogenome is 44.9%. By phylogenetic analysis using maximum likelihood method, S. flavescens showed the closest relationship with Vigna radiata in the clade of Papilionoideae.
