Significant correlation of evolutionary rates (dN) and genome complexity in different gene groups. Significant correlations were identified in NUCP, NUMT, and RRR but not NUOT genes. NUCP, nuclear encoded plastid targeted control genes; NUMT, nuclear encoded mitochondrial targeted control genes; NUOT, other nuclear encoded control genes; RRR, plastid-targeted DNA replication, recombination and repair genes.
