Table 1.
Mean percentage (±SEM) of time spent in the dark side of a light-dark choice box varies according to which photoreceptors are present and lighted side irradiance.
| Strain/Irradiance | 50.0 μW/cm2 | 5.0 μW/cm2 | 0.5 μW/cm2 |
|---|---|---|---|
| WT | 85.5 (2.2) | 82.0 (3.4) | 77.8 (2.6) |
| rd/rd | 77.5 (6.8) | 62.4 (8.2) | a41.9 (11.3) |
| OPN4−/− | 78.4 (8.3) | 83.3 (2.1) | 85.3 (2.3) |
| rd/rd;OPN4−/− | b38.8 (9.0) | -- | -- |

a
differs significantly from WT and OPN4−/− groups under the same irradiance.
b,c
differs significantly from WT, rd/rd and OPN4−/− groups under the same irradiance.
