...Takami Morita SUMMARY The evolutionary adaptations of functional genes to life at high pressure are not well understood. To elucidate the mechanisms of protein adaptation to high pressure, we cloned the myosin heavy chain (MyHC) cDNA from skeletal muscle of two deep-sea fishes, Coryphaenoides...

...Marie A. Pointer; Livia S. Carvalho; Jill A. Cowing; James K. Bowmaker; David M. Hunt SUMMARY The eyes of deep-sea fish have evolved to function under vastly reduced light conditions compared to those that inhabit surface waters. This has led to a bathochromatic shift in the spectral location...

... of 12 species of deep-sea fish of diverse phylogeny and habitat. The wavelength of peak absorption (λ max) was shifted to longer wavelengths by an average of 1.35 nm at 40 MPa (a pressure approximately equivalent to average ocean depth) relative to measurements made at one atmosphere (ca. 0.1 MPa...
