      Gr5aLEXA, Gr61a1, Df(3L)ΔGr64 triple homozygotes that also bear P{t15.3.R1} (P{t15.3.R1} rescues the lethality of Df(3L)ΔGr64 homozygosity) have impaired responsiveness to sweet chemical: sweet taste 5b sensilla GRNs virtually lack the expected responsiveness to the chemicals Sucrose, Fructose, Maltose, Trehalose, Glucose, Melezitose, Arabinose and Glycerol, as compared to controls; sweet taste 5v sensilla GRNs show the expected responsive only to Sucrose and Fructose, but lack responses to Maltose, Trehalose and Glucose.

      Expressing Gr5aUAS.cUa under the control of Scer\GAL4Gr61a.4.9 restores a small response of 5v sensilla GRNs only to Trehalose but does not affect the responses of 5b sensilla GRNs.
