The complete chloroplast genome of Cirsium setosum and its phylogenetic analysis.

ABSTRACT: Cirsium setosum is a widely distributed species of edible medicinal plant around the world. Triterpenes, flavonoids, sterols, polyphenols, and glycosides are its main medicinal ingredients. In this study, the complete chloroplast genome sequence of C. setosum was assembled and characterized from high-throughput sequencing data. The chloroplast genome was 152,405?bp in length, consisting of large single-copy (LSC) and small single-copy (SSC) regions of 83,385?bp and 18,632?bp, respectively, which were separated by a pair of 25,193?bp inverted repeat (IR) regions. The genome is predicted to contain 133 genes, including 88 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The overall GC content of the genome is 37.7%. A phylogenetic tree reconstructed by 12 chloroplast genomes reveals that C. setosum is mostly related to Cirsium arvense, which is also a Cephalanoplos plant widely distributed all over the world. The work reported the firstly complete chloroplast genome of C. setosum which may provide useful information to the evolution of Cephalanoplos.
