Fig. 1From: Comparative analyses and phylogenetic relationships of thirteen Pholidota species (Orchidaceae) inferred from complete chloroplast genomesCircular gene map of the thirteen Pholidota chloroplast genomes. Genes shown inside of the circle are transcribed clockwise, while genes annotated outside the circle are transcribed counterclockwise. The innermost darker gray depicts the GC content. Genes belonging to different functional groups are labeled with different colors, as indicated in the legendBack to article page
