Divergent evolutionary paces among eudicot plants revealed by simultaneously duplicated genes produced billions of years ago.

ABSTRACT: Polyploidization often occurs more than once along an evolutionary lineage to form extant plants. Major core eudicot plants share a whole-genome triplication (ceWGT), through which thousands of simultaneously duplicated genes are retained in extant genomes, providing a valuable starting line to check the difference in their evolutionary paces. Here, by characterizing the synonymous nucleotide substitutions (Ks) between these duplicates from 28 representative plants from 21 families, we checked the various evolutionary rates among plants among plants subjected to different rounds of extra polyploidization events. We found up to 68.04% difference in evolutionary rates among the selected plants. A statistical correlation analysis (correlation coefficient =0.57, at significant level = 0.01) in
