Summary of uncorrelated rates of evolution between symbiont and host genes

(A) Linear regression between pairwise distances and age of divergence among all Nasuia, Sulcia, and mitochondrial genes for Hawaiian leafhoppers (Nesophrosyne). Colors indicate pairwise distance of protein-coding genes in each genome. Genomes are separated by the host-plant group that the host species has specialized in. A linear regression line is mapped between pairwise distance values from the closest related species to the most divergent species in each host-plant group. The regression equation and the coefficient of determination (R²) are also reported and colorized by the genome. Outliers with a pairwise distance >0.5 were removed (4 from Nasuia, 3 from Mitochondria).

(B) Associated p values of statistical tests between evolutionary rates of genomes across all plant groups and within plant groups. Significant p value between groups indicates no correlation between means of evolutionary rate.
