The complete chloroplast genome sequence and phylogenetic analysis of <i>Tragopogon pratensis</i> L. (Asteraceae)

Currently, the phylogenetic relationships of <i>Tragopogon pratensis</i> Linnaeus (1753) remain unclear. This study presents the first report on the complete chloroplast genome of <i>T. pratensis</i>, which is a quadripartite structure with a length of 153,002 bp and containing a large single copy (LSC, 84,225 bp) region, a small single copy (SSC, 18,407 bp) region, a pair of inverted repeats (IR, 25,185 bp) regions. A total of 134 genes are identified, including 87 protein-coding genes, 8 rRNA genes, 37 tRNA genes, and 2 pseudogenes. Phylogenetic analysis revealed that <i>T. pratensis</i> is most closely related to <i>T. dubius</i> and <i>that Tragopogon</i> is a monophyletic genus.
