Sequence divergence of 25 DNA replication, recombination, and repair system genes. A Nonsynonymous (d_N) and synonymous (d_S) divergence values for 25 individual genes are plotted for C. pauciovulata and N. nucifera. Dual-targeted, plastid-targeted, and mitochondrial-targeted genes are indicated in red, green, and blue, respectively. The DNA-RRR genes are grouped into nine categories by gray parallelograms. B Boxplots of d_N and d_S values for the target groups. The box represents values between quartiles, the solid lines extend to the minimum and maximum values, and the horizontal lines in the boxes show the median values. The numbers below the boxes represent the mean values. The colors corresponding to the target groups (red, dual-targeted; green, plastid-targeted; and blue, mitochondrial-targeted genes)
