Sensory rewiring in an echolocator: genome-wide modification of retinogenic and auditory genes in the bat Myotis davidii.
Bottom Line: Myotis davidii is a bat species that echolocates and possesses dim- but not daylight-adapted vision whereas the black flying fox (Pteropus alecto) has highly developed day vision but does not echolocate.In a second approach genome-wide codon usage bias (CUB) was compared between the two bat species.Together, they help explain how natural selection has reduced physiological costs associated with the development of a smaller eye poorly adapted to day vision but that also contribute to enhanced dim light vision and the hearing adaptations consonant with echolocation.

Mentions: Of the 19 visual perception genes identified as inactivated or missing in the naked mole rat, we identified five that have also become pseudogenes in M. davidii but not P. alecto (CYP1A2, RBP3, GUCY2F, CRYBB1, and GRK7; Figure 1). Taxonomically the naked mole rat H. glaber is placed within rodents. Despite some exceptional traits the overall properties of the H. glaber genome are similar to other mammals (Kim et al. 2011) making the comparison to the two bat species reasonable.
