The complete chloroplast genome sequence of an invasive plant, Tragopogon dubius Scopoli (asteraceae)

Tragopogon dubius Scopoli is native to Europe and western Asia and is considered an invasive plant in China. In this study, the complete chloroplast genome of T. dubius was obtained using high-throughput next-generation sequencing technology. The whole chloroplast genome was 153,017 bp long with a GC content of 38% and comprised 130 genes (86 protein-coding genes, 36 tRNA genes, and 8 rRNA genes). Phylogenetic analysis based on the concatenated chloroplast protein-coding sequences showed that T. dubius is most closely related to Tragopogon pratensis. This study provides valuable genetic data for further phylogenetic analysis and molecular identification of species in the genus Tragopogon.
