Molecular components of the clock system identified in fast and slow skeletal muscles of Chinese Perch and myogenic genes with daily rhythmic expression. The green and red oval represent genes involved in the peripheral clock components in Chinese Perch skeletal muscles, which is related with the muscle fiber. They comprise members of the transcriptional activator arm (in red: arntl1, arntl2, clock and npas2), transcriptional repressor arm (in green: cry1, cry2, cry3, cry-dash, per1, per2, per3 and tim) and nuclei (in nucleus: nr1d1, nr1d2 and rorα). The daily rhythmicity of mbnl1, mrf4, mstn, myf5, myoD, myoG and pcna play a crucial role in fast muscle specification, and foxk2, mrf4, mstn, myf5 and pcna play an important role in terminal slow muscle differentiation
