The complete chloroplast genome sequence of a critically endangered orchid Paphiopedilum gratrixianum (Orchidaceae).

ABSTRACT: Paphiopedilum gratrixianum is a critically endangered orchid with extremely small populations and of great horticulture value. We assembled and annotated the complete chloroplast genome of P. gratrixianum in this study. The genome is 157,292 bp in length and 35.8% of the GC content. It encodes a total of 102 unique genes, including 68 protein-coding genes, 30 tRNA genes, and four rRNA genes. Phylogenetic analysis results strongly supported that it was closely related to P. tranlienianum. The complete chloroplast genome of P. gratrixianum (GenBank accession number: MW284890) can be useful for the evolutionary study in Orchidaceae.

The complete chloroplast genome sequences of an endangered orchid species Paphiopedilum wenshanense (Orchidaceae).

Project description:Paphiopedilum wenshanense, a species of the family Orchidaceae, is endangered in the world with highly ornamental and biological value, the morphology of P. wenshanense is very similar to its relative species, P. bellatulum and P. concolor. However, there are few studies on the molecular biology and phylogeny of this species currently. Therefore, we report its complete chloroplast (cp) genome sequence at the first time, hoping to provide a foundation for its future phylogenetic analysis. The complete chloroplast genome of P. wenshanense was 161,750 bp in size, which contained a large single-copy (LSC) region of 90,656 bp, a small single-copy (SSC) region of 1886 bp, and two inverted repeat (IR) regions of 34,604 bp each. The total GC content was 35.66%. The genome encodes 38 transfer RNA genes, eight ribosomal RNA genes, and 80 protein-coding genes. The phylogenetic analysis indicated that the genetic relationship between P. wenshanense and P. concolor was very close.
