Flies were raised for six d below either continuous dark condition or even a 12 hr light/12 hr dark cycle. (B) The GMR-driven wild-type Gaq transgene, but not the V303D mutant transgene, rescues visual degeneration on the V303D mutant. Scale bars are indicated in the bottom. (C) Retinal degeneration didn’t take place in similarly dark/light-treated 6-d-old eyes from 1 Gaq. Rapid degeneration of V303D eyes is comparable to norpA mutants, and could not be relieved by a calx mutation.

Therefore, the defective ERG response in our mutant is caused by a defective Gaq gene. It can be worth noting that just before our work, only a couple of genetic backgrounds have been shown to make a flat ERG response: single mutations in the rdgA gene that encodes diacylglycerol kinase (Masai et al. 1997; Raghu et al. 2000) as well as the norpA gene that encodes PLC (McKay et al. 1995; Kim et al. 2003), or double mutations in the trp and trpl channels (Leung et al. 2000, 2008; Yoon et al. 2000). This suggests that the new Gaq mutation that we identified is probably to become among the list of strongest mutations with the phototransduction cascade in Drosophila.GaV303D flies undergo speedy retinal degeneration q A lot of mutants inside the Drosophila phototransduction cascade show light-dependent retinal degeneration, including flies with previously identified Gaq mutants (Hu et al. 2012). We raised GaV303D adults q below either standard light-dark cycles or continual dark situations, and assayed retinal degeneration working with EM. We observed serious degeneration in eyes taken from 6-d-old GaV303D mutants raised under q light-dark cycles (Figure 3A), but not from these reared in constant dark (Figure 3A). This degree of light-dependent retinal degeneration was much more extreme than in previously identified Ga1 mutants (Figure 3B). q Below similar rearing situations, Ga1 and Ga961 mutant eyes show q q visible degeneration only just after 21 d posteclosion (Hu et al. 2012).
