The complete chloroplastic genomes of six Paphiopedilum species

Phylogenetic relationships among some species in Paphiopedilum genus cannot be effectively determined by morphological features alone or through analysis of nuclear or chloroplast DNA fragments. In order to provide aid in understanding the evolutionary and phylogenetic relationship in Paphiopedilum at chloroplast (cp) genome-scale level, the complete cp genomes of six Paphiopedilum species were newly sequenced in this study , and three other published cp genome sequences of Paphiopedilum were included in the comparative analyses.
