Comparative analysis of vision-related genes. a Comparison of the number of vision-related receptors and transcription factors in representative arthropod species, with the species phylogenetic tree on the left and the corresponding gene counts on the right. b Distribution of opsin genes identified in the O. oratoria genome on chromosomes. c Phylogenetic tree of opsin genes in the O. oratoria (left) and analysis of conserved domains (right). d Inter-species evolutionary analysis of opsin genes in different species, including long-wavelength sensitive (LWS), medium-wavelength sensitive (MWS), and short-wavelength sensitive (SWS) opsin genes
