Fig. 4From: Transcriptome-wide mining, characterization, and development of microsatellite markers in Lychnis kiusiana (Caryophyllaceae)Correlation of synonymous and nonsynonymous substitution rates of SNPs. The solid red line indicates the dN/dS ratio is equal to one. The dashed line represents the regression, which was analyzed using dN and dS for all unigenes. The red circles represent unigenes with dN/dS ratios > 1Back to article page
