Additional file 10 of Comparative genomics of the coconut crab and other decapod crustaceans: exploring the molecular basis of terrestrial adaptation

Additional file 10 Figure S3. The concept of nuclear expressed gene expansion supplementing atypical mitochondrial DNA. A previous study has shown that the coconut crab’s mitochondrial tDNAs are notably mutated compared to other anomurans. In the present study, we observed within the nuclear genome of the coconut crab highly proliferated genes that are annotated with mitochondrial and microtubule function, and a massively proliferated kinesin, kif22, that has the most mitochondrial targeting signals within its homologous gene sequences compared to other decapods. This points to the nuclear expressed protein complement having a more prominent supplementary role with respect to the mitochondrion in the coconut crab. This ideogram was drawn with Google Drawings.
