Comparative Phylogenomic Study of Malaxidinae (Orchidaceae) Sheds Light on Plastome Evolution and Gene Divergence.

ABSTRACT: Malaxidinae is one of the most confusing groups in the Orchidaceae classification. Previous phylogenetic analyses have revealed that the relationships between the taxa in Malaxidinae have not yet been reliably established, using only a few plastome regions and nuclear ribosomal internal transcribed spacer (nrITS). In the present study, the complete plastomes of Oberonia integerrima and Crepidium purpureum were assembled using high-throughput sequencing. Combined with publicly available complete plastome data, this resulted in a dataset of 19 plastomes, including 17 species of Malaxidinae. The plastome features and phylogenetic relationships were compared and analyzed. The results showed the following: (1) Malaxidinae species plastomes possess the quadripartite structure of ty
