The complete genome sequence of the chloroplast of Bidens aurea

Abstract

Bidens aurea (Asteraceae), a native of tropical America is now widespread in Asia and the Americas. We explored the B. aurea 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 Bidens taxa were divided into five major clades, and B. aurea 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.
