Fig. 8. Developmental plasticity of myofibrillar protein composition and slow
muscle innervation patterns in the myotomal muscles of Atlantic herring
(Clupea harengus) reared at 12 or 5 °C. After hatching,
temperature was allowed to rise, mimicking a seasonal warming. MyHC, myosin
heavy chains; LC2, myosin light chain 2; TNI, troponin I; TNT, troponin T;
LC3f, myosin light chain 3. Blue, embryonic pattern; yellow, adult
pattern. Data from Johnston et al.
(1997,
1998).
