The complete chloroplast genome of the endangered plant Paphiopedilum wardii (Orchidaceae)

Abstract

Chloroplast (cp) genome sequences provide a valuable source for phylogenetic analysis, which becomes a popular tool for population and phylogeny in a recent report. Here, the complete chloroplast genome of the Paphiopedilum wardii has been reconstructed from the whole-genome Illumina sequencing data. The circular genome is 169,820 bp in size and comprises a pair of inverted repeat (IR) regions of 33,641 bp each, a large single-copy (LSC) region of 98,872 bp and a small single-copy (SSC) region of 3666 bp. The total GC content is 33.8%, while the corresponding values of the IR regions, LSC, and SSC and are 38.7%, 31.7% and 26.7%, respectively. The chloroplast genome contains 151 genes, including 91 protein-coding genes, eight ribosomal RNA genes and 52 transfer RNA genes. Two genes ( ndhA and ndhB ) are pseudogenized or lost in its cpDNA. The maximum-likelihood phylogenetic analysis showed a close relationship with P. armeniacum in Orchidaceae. Our findings provide useful information for phylogenetic and evolutionary research of Paphiopedilum species.

The complete chloroplast genome of Aesculus chinensis

“…The chloroplast genome sequences have been utilized as reliable tools for phylogeneitc and evolutionary research (Wang et al 2018). In recently, many chloroplast genomes of valuable plants have been reported Liu and Han, 2018;Zheng et al 2018;Wang et al 2018;Kwon et al 2019;Yang et al 2019;Zhu and Sun 2019). To facilitate its genetic research and contribute to its utilization, we reported the complete chloroplast genome sequence of A. chinensis based on Illumina HiSeq X Ten.…”

Characterization of the complete chloroplast genome sequence of Conyza canadensis and its phylogenetic implications

“…The chloroplast genome sequences have been utilized as reliable tools for phylogenetic and evolutionary research (Shi et al 2012;Cheng et al 2018;Wang et al 2018). In this study, we conducted the sequencing of C. canadensis chloroplast genome and the phylogenetic analysis with other Asteraceae chloroplast genomes.…”
