Two-dimensional RFLP analyses reveal megabase-sized clusters of rRNA gene variants in Arabidopsis thaliana, suggesting local spreading of variants as the mode for gene homogenization during concerted evolution.

Abstract excerpt

Eukaryotic genes encoding the precursor of 18S, 5.8S and 25S ribosomal RNA (rRNA genes or rDNA) are virtually identical within a species, yet they evolve rapidly between species, a phenomenon known as concerted evolution. The mechanisms by which sequence homogenization and fixation of new rRNA ge...
