Scer\GAL80ChAT.7.4P, Scer\GAL4Gr43a-GAL4, Gr43aUAS.cMa partially rescues Gr43aGAL4
Expression of Gr43aScer\UAS.cMa under the control of Scer\GAL4Gr43a-GAL4 rescues the loss of sugar preference in two-choice preference assays seen in Gr43aGAL4 mutant larvae. Preferences for fructose, glucose, melezitose and sorbitol are all restored.
Expression of Gr43aScer\UAS.cMa under the control of Scer\GAL4Gr43a-GAL4 (restricted to the brain using Scer\GAL80ChAT.7.4P) rescues the defects in glucose and sorbitol preference in two-choice preference assays seen in Gr43aGAL4 mutant larvae. The preference for fructose is not fully rescued and is still severely reduced.
Expression of Gr43aScer\UAS.cMa under the control of Scer\GAL4Gr43a-GAL4 rescues the reduced Ca[2+] response to fructose which is seen in taste neurons of the foreleg in Gr43aGAL4 homozygotes.
Expression of Gr43aScer\UAS.cMa under the control of Scer\GAL4Gr43a-GAL4 rescues a preference for 100mM sorbitol over water in a modified capillary feeding assay in Gr43aGAL4 homozygotes. This rescue is still seen in the presence of Scer\GAL80Cha.7.4P (which limits expression to the Scer\GAL4Gr43a-GAL4-expressing neurons in the brain).
Expression of Gr43aScer\UAS.cMa under the control of Scer\GAL4Gr43a-GAL4 rescues the over-consumption of sucrose and glucose seen in Gr43aGAL4 homozygotes in a modified capillary feeding assay.
Expression of Gr43aScer\UAS.cMa under the control of Scer\GAL4Gr43a-GAL4 in the presence of Scer\GAL80Cha.7.4P rescues the over-consumption of a sorbitol and sucralose solution seen in Gr43aGAL4 homozygotes in a modified capillary feeding assay.
