Abstract
The complete plastid genome of Gentiana leucomelaena Maxim., belonging to the most species-rich section Chondrophyllae in Gentiana, was determined and analyzed in this study. It has a circular-mapping molecular with the length of 131,856 bp, the shortest one among all available Gentiana plastomes. Gentiana leucomelaena has gene mutation, for example ndh and rpl2 intron, and reversed SSC region comparing with the available species in sections Cruciata, Frigida, Kudoa, Isomeria and Microsperma. Phylogenetic analysis showed that G. leucomelaena clustered together with section Cruciata with a long branch. The plastome provides in this work will contribute to elucidate the phylogenetics and evolution in Gentiana.
