Fmr15-HA-1014/Fmr15-HA-1014 mutants do not exhibit defective learning in an aversive conditioning assay, but do exhibit severe defects in a reversal-learning paradigm, with a third-odor preference assay showing an inability to forget the first aversive odor association after training with a second aversive odor; these flies also show a significantly slower decay in memory performance with increased time after training, and interference-induced forgetting is blocked in these mutants, as compared to wild type.
Fmr15-HA-1014 has abnormal learning | adult stage phenotype, suppressible | RU486 conditional by Scer\GAL4elav.Switch.PO/Rac1V12.UAS
Fmr15-HA-1014 has abnormal learning | adult stage phenotype, non-suppressible by Scer\GAL4elav.Switch.PO/Rac1N17.UAS
Expression of Rac1V12.Scer\UAS (but not Rac1N17.Scer\UAS) under the control of Scer\GAL4elav.Switch.PO (and feeding with RU486 to induce expression via the GeneSwitch system) significantly suppresses the reversal-learning defect observed in Fmr15-HA-1014/Fmr15-HA-1014 mutants.
