Flies had been raised for six d under 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 of your V303D mutant. Scale bars are indicated at the bottom. (C) Retinal degeneration didn’t happen in similarly dark/light-treated 6-d-old eyes from 1 Gaq. Fast 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 is actually worth noting that before our work, only a number of genetic backgrounds were shown to produce a flat ERG response: single mutations within the rdgA gene that encodes diacylglycerol kinase (Masai et al. 1997; Raghu et al. 2000) and 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 likely to become one of the strongest mutations on the phototransduction cascade in Drosophila.GaV303D flies undergo fast retinal degeneration q Numerous mutants in the Drosophila phototransduction cascade display light-dependent retinal degeneration, such as flies with previously identified Gaq mutants (Hu et al. 2012). We raised GaV303D adults q under either typical light-dark cycles or continuous dark conditions, and assayed retinal degeneration utilizing EM. We observed extreme degeneration in eyes taken from 6-d-old GaV303D mutants raised beneath q light-dark cycles (Figure 3A), but not from those reared in continuous dark (Figure 3A). This degree of light-dependent retinal degeneration was extra serious than in previously identified Ga1 mutants (Figure 3B). q Beneath comparable rearing situations, Ga1 and Ga961 mutant eyes display q q visible degeneration only right after 21 d posteclosion (Hu et al. 2012).
