Additional file 6: of GC content of vertebrate exome landscapes reveal areas of accelerated protein evolution

Figure S5. Pairwise comparisons of landscapes of genome-wide GC content mRNAs from a mammalian and reptilian species. Panel A Loxodonta africana (African elephant) versus Pogona vitticeps (bearded dragon), Panel B Rhinolophus sinicus (Chinese horseshoe bat) versus Aquila chrysaetos canadensis (American golden eagle), Panel C Physeter catodon (sperm whale) versus Chrysemys picta (painted turtle). Genes were ranked on the order of the human genome and GC content was calculated using a sliding window approach of a gene and its 100 surrounding genes. The three species from each clade have a similar GC content profile, but major differences can be seen between the two clades. There are no clear differences observed for species which live on land (A), can fly (B) and swim (C). (PDF 4372 kb)
