Genomic evidence of visual opsin genes in P. hakonensis and P. brandtii. A Genes involved in phototransduction cascade are shown in the colored circles; a REG was marked in purple circle. B The three-dimensional structure of RH1 protein. C The rh1 gene had specific AA replacement in P. hakonensis and P. brandtii based on sequence alignments
