Characterization of the complete chloroplast genome of Paphiopedilum micranthum, an Endangered orchid in China.

ABSTRACT: Paphiopedilum micranthum is a rare species of terrestrial herb in the Orchidaceae. It is naturally distributed in southwestern China and north of Vietnam. Here, we reported the first complete chloroplast genome (cpDNA) of P. micranthum. The length is 163,243 bp, with 129 genes, including 77 protein coding genes, 38 tRNA genes, and 8 rRNA genes. It includes two inverted repeat regions (IRs) of 36,128 bp each, which were separated by a large single copy region (LSC) of 89,245 bp and a small single copy region (SSC) of 1742 bp. The overall GC-content of the whole chloroplast is 35.8%, while the corresponding values of the LSC, SSC, and IR regions are 33.2, 20, and 39.3, respectively. The complete chloroplast genome sequence of P. micranthum (GenBank accession number: MN535014) can be used as a useful resource for the evolutionary biology study of phylogenetic studies in Orchidaceae.

The complete chloroplast genome of an endangered orchid Paphiopedilum spicerianum.

Project description:Paphiopedilum spicerianum (H. G. Reichenbach) Pfitzer is an endangered and threatened orchid species in China. The genetic and molecular data of this orchid species is deficient. With the aim to identify appropriate chloroplast markers for the use in a conservation biology study, the complete chloroplast genome of P. spicerianum was reported. We found that the chloroplast genome of P. spicerianum is 157,292 bp in length, containing a large single-copy region of 87,252 bp, a small single-copy region of 1828 bp, and a pair of inverted repeats of 34,106 bp. Genome annotation predicted 105 unique genes, including 71 protein-coding genes, 30 tRNAs, and four rRNAs. Fourteen genes contained one intron and two genes (clpP and ycf3) had two introns. The GC content of the P. spicerianum was 35.8%. Phylogenetic analysis indicated P. spicerianum was closely related to P. purpuratum.

Characterization of the complete chloroplast genome of orchid family species Paphiopedilum bellatulum.

Project description:The genus Paphiopedilum is well known as the lady's slipper orchid in Orchidaceae family. Paphiopedilum bellatulum (Rchb.f.) Stein 1892, has important medicinal and ornamental value, which occurs in the tropical Asia. However, in recent decades, it was threatened with extinction by significantly reduced small population size. In this study, we sequenced and characterized the complete chloroplast genome of P. bellatulum based on the Illumina Hiseq platform. The size of P. bellatulum chloroplast genome was 156,567 bp, including a large single-copy (LSC) region of 88,243 bp, a small single-copy (SSC) region of 3652 bp, and two inverted repeat regions (IRs) of 32,336 bp. The overall GC contents of the chloroplast genome were 35.71%. A total of 122 genes were annotated, including 76 protein-coding genes, 38 transfer RNAs (tRNAs), and eight ribosomal RNAs (rRNAs). The phylogenetic analysis indicated that P. bellatulum formed a close relationship with another Paphiopedilum species P. wenshanense. The results will provide helpful genetic resource for further phylogenetic studies of the genus Paphiopedilum.

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

Project description: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.
