Figure 1. Expression pattern of Cry1* in the retinal S1 cones of the studied mammalian species.
Color codes are given below the figure. The species are ordered according to their phylogenetic relationships38,39,40,41,42, branch lengths are not scaled to time. Cry1* label is only present in canoid carnivores and in some primates (species shown in red), and it is restricted to the outer segments of the S1 cones. In two primates Cry1* label is faint (shown in orange). Most species possess S1 cones but show no Cry1* label (blue). Some species do not possess S1 cones and show no Cry1* label (black). A more detailed tree of Carnivora is given in Supplementary Fig. S1. A, Afrotheria; X, Xenarthra; E, Euarchontoglires; L, Laurasiatheria.
