Characterization of the complete chloroplast genome of Taibaisanqi (Tongoloa silaifolia).

Tongoloa silaifolia, known as a traditional Chinese medicine Taibaisanqi, is a perennial herb of Apiaceae. In this study, the complete chloroplast genome of T. silaifolia was determined through Illumina sequencing method. The chloroplast genome of T. silaifolia was 161,122 bp in length and contained a pair of IR regions (30,824 bp) separated by a small single-copy region (17,553 bp) and a large single-copy region (81,921 bp). This chloroplast genome is encoded with 137 genes including 92 CDS, 37 tRNA genes, and 8 rRNA genes. The overall GC content of T. silaifolia cp genome is 37.7%. By phylogenetic analysis using maximum likelihood method, T. silaifolia showed the closest relationship with Chuanminshen violaceum and Hansenia species.
