The complete chloroplast genome of Paphiopedilum tranlimianum (Orchidaceae)

Abstract

Chloroplast (cp) genome sequences have become a useful tool for phylogeneitc and evolutionary study in recent reports. Here the complete chloroplast genome of the Paphiopedilum tranlimianum has been reconstructed from the whole-genome Illumina sequencing data. The circular genome is 162,127 bp in size, and comprises of a pair of inverted repeat (IR) regions of 31,457 bp each, a large single-copy (LSC) region of 91,711 bp, and a small single-copy (SSC) region of 7,502 bp. The total GC content is 35.4%, while the corresponding values of the LSC, SSC, and IR regions are 32.7%, 26.9%, and 40.9%, respectively. The chloroplast genome contains 133 genes, including 87 protein-coding genes, eight ribosomal RNA genes, and 38 transfer RNA genes. Three genes (ndhA, ndhE, and ndhI) are pseudogenized or lost in its cpDNA. The Maximum-Likelihood phylogenetic analysis showed a close relationship with P. niveum in Orchidaceae. Our findings provide useful information for phylogenetic and evolutionary research of Paphiopedilum species.
