The complete chloroplast genome sequence of Cypripedium tibeticum King Ex Rolfe (Orchidaceae).

ABSTRACT: In this study, we determined the complete chloroplast genome of Cypripedium tibeticum, an endangered species in China. The plastome is 159,223 bp in length, with a large single-copy region (LSC) of 86,537 bp, a small single-copy region (SSC) of 17,552 bp, and a pair of inverted repeat regions (IRs) of 27,567 bp each. It contains 133 genes, including 87 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. The overall GC content was 36.9%, while the corresponding values in the LSC, SSC, and IR regions are 34.6, 30.4, and 42.6%, respectively. The phylogenetic analysis showed that C. tibeticum was closely related to its congeners and the classification of five subfamilies of Orchidaceae was also highly supported.

The complete chloroplast genome sequence of Paphiopedilum henryanum (Orchidaceae).

Project description:Paphiopedilum henryanum Braem 1987 is a critically Endangered terrestrial orchid mainly occurred around the southern China and northern Vietnamese borders. Recently, the population size of this species has been sharply declined due to many threats such as climate change, habitat loss, and narrow distribution. In this study, the complete chloroplast genome sequence of P. henryanum was determined from Illumina pair-end sequencing data. The chloroplast genome was 155,886 bp in length, including a large single copy region (LSC) of 87,573 bp, a small single-copy region (SSC) of 2,831 bp, and a pair of inverted repeated regions (IRa and IRb) of 32,741 bp each. The chloroplast genome contained 121 genes corresponding to 76 protein-coding genes, 8 ribosomal RNA (rRNA) genes and 37 transfer RNA (tRNA) genes, respectively. The results of phylogenetic analysis indicated that P. henryanum was closely related to P. violascens and P. venustum in the genus Paphiopedilum based on sixteen whole chloroplast genome sequences. The results would provide a valuable resource for future genetic studies of Paphiopedilum.
