The complete chloroplast genome sequence of the threatened Cypripedium calceolus (Orchidaceae).

ABSTRACT: The complete chloroplast genome of Cypripedium calceolus, a rare species in the family Orchidaceae was reported in this study. The genome size is 175,122 bp in length, and contains four sub-regions: 97,486 bp of large single copy (LSC) and 22,260 bp of small copy (SSC) regions, separated by 27,688 bp of inverted repeat (IR) regions. A total of 133 genes were annotated, including 87 protein-coding genes, 38 tRNA genes and 8 rRNA genes. The GC content of this cp genome is 34.36%. Phylogenetic analysis revealed a close relationship between C. calceolus with C. japonicum and C. formosanum. This is the first complete cp genome for C. calceolus that would be useful for conservation and phylogenetic studies of this species.

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.
