The complete chloroplast genome sequence of Vernonia amygdalina Delile

摘要

Vernonia amygdalina Delile is widely used in folkloric medicine for the treatment of various diseases. In this study, the complete chloroplast genome of V. amygdalina Delile was reported, which was assembled and annotated base on genome high-throughput sequencing data. This work provided the clues for the taxonomy of the herb and the potential to utilize the chloroplast genome sequence as a new study target. The length of V. amygdalina Delile chloroplast genome was 153,133bp, with two single-copy regions, each has the length of 84,245bp and 13,152bp respectively. This region were separated by two inverted repeat regions with 27,868bp in length. It was predicted to consist of 131 genes in total, including 86 protein-coding genes, 37 tRNA genes, 8 rRNA genes with GC content at 37.68%. Phylogenetic analysis by RAxML (Random Axelerated Maximum Likelikhood) showed V. amygdalina Delile is closest to Sonchus webbii in Compositae .
