Abstract

Our data provide evidence that numit rps13 genes in rosids have experienced adaptive sequence evolution and convergent evolution with mt rps13. Co-expression of numit rps13 and mt rps13 and purifying selection on both genes in Malus suggest that both are functional. The three organellar rps13 genes in rosids provide a distinctive case of gene duplication involving the co-evolution of the nuclear and cytoplasmic genomes.
