cDNA clones encoding the myogenic regulatory factors, myogenin, MyoD and myf‐5 were cloned by reverse‐transcription polymerase chain reaction from larvae and embryos of the common carp. MEF2 cDNAs were also identified from an adult carp cDNA library. During the period of somite formation for carp, myf‐5 was the first factor to be expressed followed by MEF2C and MyoD, then myogenin and MEF2A, and finally skeletal myosin heavy c...
