Ribosomal DNA (rDNA) is one of the most conserved genes in eukaryotes. The multiples copies of rDNA in the genome evolve in a concerted manner, through unequal crossing over and/or gene conversion, two mechanisms related to homologous recombination. Recombination increases local GC content in several organisms through a process known as GC-biased gene conversion (gBGC). gBGC has been well characterized in mammals, birds, and grasses, but its phylogenetic distribution across the tree of life is… CONTINUE READING
