The complete genome sequence of the chloroplast of <i>Bidens aurea</i>

<i>Bidens aurea</i> (Asteraceae), a native of tropical America is now widespread in Asia and the Americas. We explored the <i>B. aurea</i> chloroplast genome and conducted a phylogenetic analysis. The chloroplast genome was circular, consisting of a large single copy (LSC) of 83,909 base pairs (bp), a small single copy (SSC) of 18,407 bp, and two inverted repeat regions (IR) of 24,729 bp each. Phylogenetic analysis showed that the 19 <i>Bidens</i> taxa were divided into five major clades, and <i>B. aurea</i> was most closely related to two species. Our findings offer a high-quality B. aurea chloroplast genome, aiding DNA barcode development and evolutionary history reconstruction.
