Plausible contribution of different opsins to ERG during dark and light adaptation. Black dots and error bars (± SE, n = 7 for dark-adapted, n = 8 for light-adapted) indicate the relative ERG sensitivities reproduced from Matsuo et al. (2019) [6]. Red lines are the linear summations of four rhodopsin nomograms (Additional file 10: Fig. S9), experimentally obtained for Gq-rhodopsin (Fig. 4a), xenopsin (Fig. 4b), Opn5A (Fig. 5b), estimated based on the wavelength of the maximal relative response of Opn5B (Fig. 4d) and using 360 nm-pigment for UV sensitivity of Opn5A and Opn5B (Fig. 4c, d)
