Daily Rhythmicity of Clock Gene Transcripts in Atlantic Cod Fast Skeletal Muscle
Figure 1
Radiation trees of representative clock genes from the transcriptional activation (A: arntl) and repression (B: per) arms of the Atlantic cod molecular clock system.
The unrooted trees were constructed by maximum likelihood analysis using an LG substitution model with four substitution rate categories. Branch support was calculated by aLRT SH-like tests. Orthologous genes from teleosts and tetrapods were used in the construction of the phylogenetic trees. Atlantic cod clock genes cloned in the present study are highlighted in red bold font. Teleostean clades are circled by a dotted red line. Phylogenetic trees of other gene families are provided in Figure S1A-I.
