Fig. 2

The mean (± standard errors of the mean (SEM)) expression values of cone opsin genes relative to housekeeping genes according to separate quantitative polymerase chain reaction (qPCR) experiments for individuals grown under green light (Green, N = 8) and those under orange light (Orange, N = 6). Gene expression values of cone opsins were normalized to the geometric mean value of the expression of housekeeping genes
