The complete chloroplast genome sequence of Chrysanthemum indicum

Abstract

Chrysanthemum indicum, an important medicinal plant of Asteraceae, had a long history in use for medicine in China. In this study, the complete chloroplast genome of C. indicum was sequenced by a 454 sequencing platform, and the structure of the obtained chloroplast genome was also analyzed. The complete chloroplast genome of C. indicum was 150 972 bp in length and had a pair of inverted repeats (IR, 24 956 bp) separated by a large (LSC, 82 741 bp) and small single copy (SSC, 18 319 bp) regions. Its total GC content was 37.48%. There were 126 chloroplast genes including 83 protein-coding genes, 35 tRNAs and eight rRNAs were successfully annotated. Sixteen genes contained one or two introns. Phylogenetic analyses declared that the chloroplast genome could distinguish C. indicum from its closely related species and might become a potential super barcode for the identification of these species.
