Comparative chloroplast genomes of photosynthetic orchids: insights into evolution of the Orchidaceae and development of molecular markers for phylogenetic applications.

ABSTRACT: The orchid family Orchidaceae is one of the largest angiosperm families, including many species of important economic value. While chloroplast genomes are very informative for systematics and species identification, there is very limited information available on chloroplast genomes in the Orchidaceae. Here, we report the complete chloroplast genomes of the medicinal plant Dendrobium officinale and the ornamental orchid Cypripedium macranthos, demonstrating their gene content and order and potential RNA editing sites. The chloroplast genomes of the above two species and five known photosynthetic orchids showed similarities in structure as well as gene order and content, but differences in the organization of the inverted repeat/small single-copy junction and ndh genes. The organization of t
