Fig. 7From: Comparative and phylogenetic analyses of six Kenya Polystachya (Orchidaceae) species based on the complete chloroplast genome sequencesSliding window analysis of six Polystachya cp genomes. (A)Â Comparison of the nucleotide variability (Pi) among protein-coding regions; (B)Â Comparison of the nucleotide variability among non-coding regions (including IGS and introns). X-axis: position of the midpoint of a window; Y-axis: nucleotide diversity of each window. The different colored lines at the bottom delineate where these genes are located in different plastome regionsBack to article page
