Abstract
Currently, the phylogenetic relationships of Tragopogon pratensis Linnaeus (1753) remain unclear. This study presents the first report on the complete chloroplast genome of T. pratensis, 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 T. pratensis is most closely related to T. dubius and that Tragopogon is a monophyletic genus.
