Summary

We sequenced the Bidens aurea chloroplast genome, revealing its structure and evolutionary relationships. This high-quality genome data aids DNA barcoding and understanding the Bidens genus evolution.

Area Of Science

Botany
Genomics
Phylogenetics

Background

Bidens aurea, native to tropical America, has a widespread distribution across Asia and the Americas.
Understanding the genetic makeup and evolutionary history of widely distributed plant species is crucial for conservation and taxonomic studies.

Purpose Of The Study

To sequence and characterize the complete chloroplast genome of Bidens aurea.
To perform a phylogenetic analysis of Bidens taxa using chloroplast genome data.
To provide a high-quality reference genome for Bidens aurea.

Main Methods

Whole chloroplast genome sequencing of Bidens aurea.
Bioinformatic analysis to assemble and annotate the chloroplast genome.
Phylogenetic analysis using sequence data from 19 Bidens taxa.

Main Results

The Bidens aurea chloroplast genome is circular, with specific lengths for the large single copy (LSC), small single copy (SSC), and inverted repeat (IR) regions.
Phylogenetic analysis resolved 19 Bidens taxa into five major clades.
Bidens aurea was found to be most closely related to two specific species within the Bidens genus.

Conclusions

The study provides the first high-quality chloroplast genome sequence for Bidens aurea.
The genomic data will facilitate DNA barcode development for species identification and authentication.
The phylogenetic analysis enhances the understanding of evolutionary relationships within the Bidens genus.
