Gal80 control of Gal4 dependent UAS-dNSF2^E/Qphysiological phenotypes. Excitatory Junctional Potentials (EJPs) were recorded from Muscle 6 and their amplitudes were measured. The dNSF2^E/Q neuromuscular junctions are significantly overgrown compared to wild-type. When Gal80; elavGal4 > UAS-dNSF2^E/Q larvae were raised at 25°C their EJP amplitude was comparable to that of all the control genoptypes. When these larvae were raised 30°C their EJPs were significantly smaller, comparable to the mutant, elavGal4 > UAS-dNSF2^E/Q phenotype (black bars). The bars represent mean ± SEM EJP amplitude (mV) with the number of muscles recorded indicated within each bar.
