Analysis of the chloroplast genome and phylogenetic evolution of Bidens pilosa.

ABSTRACT: Chloroplast genomes for 3 Bidens plants endemic to China (Bidens bipinnata Linn., Bidens pilosa Linn., and Bidens alba var. radiata) have been sequenced, assembled and annotated in this study to distinguish their molecular characterization and phylogenetic relationships. The chloroplast genomes are in typical quadripartite structure with two inverted repeat regions separating a large single copy region and a small single copy region, and ranged from 151,599 to 154,478 bp in length. Similar number of SSRs and long repeats were found in Bidens, wherein mononucleotide repeats (A/T), forward and palindromic repeats were the most in abundance. Gene loss of clpP and psbD, IR expansion and contraction were detected in these Bidens plants. It seems that ndhE, ndhF, ndhG, and rpl32 from the Bidens
