Detailed Description
Statement
Reference

Plc21CA/+ has no effect on evoked neurotransmission.

The electroantennograms of Plc21CA/+ animals show a small but significant decrease in amplitude compared to controls in response to a number of odours (ethyl acetate, butanol, propionic acid, benzaldehyde and iso-amyl acetate).

The electroantennograms of Plc21Ck31911/Plc21CA animals show a significant decrease in amplitude compared to controls in response to a number of odours (ethyl acetate, butanol, propionic acid, benzaldehyde and iso-amyl acetate).

Statement
Reference

One copy of Plc21CA does not prevent the compensatory increase in quantal content seen in the NMJs GluRIIASP16 mutant larvae that have reduced quantal size. Evoked neurotransmission is therefore unaffected.

The electroantennograms of Gα49B221c/Plc21CA and Gα49B1370/Plc21CA double heterozygous animals show a significant decrease in amplitude compared to controls in response to a number of odours (ethyl acetate, butanol, propionic acid, benzaldehyde and iso-amyl acetate) and the reduction in the double heterozygotes is significantly greater than that expected to arise from a mere additive effect of the single heterozygous phenotypes.
