Fig. 4From: Extensive genomic rearrangements mediated by repetitive sequences in plastomes of Medicago and its relativesComparison of nucleotide diversity (Pi) among the 20 species. X-axis: names of genes or intergenic regions, Y-axis: nucleotide diversity (Pi) of each region. We identified 8 genes (Pi > 0.04) and 16 intergenic regions (Pi > 0.1) as highly divergent regions and colored them with redBack to article page
