Reference

PQBP1PL00109 is expressed in the cell bodies in the proximity of the antennal lobe and the antennal nerve. Expression of PQBP1PL00109 surrounds the projection neurons that fasciculate with the antennal nerve and innervate the antennal lobe.

Detailed Description
Statement
Reference

PQBP1PL00109 mutant flies exhibit lower electroretinogram amplitudes than wild type flies.

The photoreceptor cells in newly eclosed PQBP1PL00109 mutant flies have split and disorganised microvilli as well as a reduced rhabdomere size.

At 50% of pupal development the actin-based microvilli in PQBP1PL00109 mutant photoreceptor cells are irregularly arranged and loosely packed compared to the tightly packed rows in wild type pupae. Microvillus density and length are both reduced at this stage, but elongation is normal at 60-80% pupal development. Proximal to distal elongation of the photoreceptor cells takes place normally but ommatidium length is reduced.

Heterozygous and homozygous flies have a significantly shorter average lifespan (25.8 days and 17.5 days respectively) than wild-type controls (33.4 days). The 90% maximum lifespan is also reduced (43 and 32 days respectively, compared to 47 days for wild type).

Homozygous mutants show a significant decrease in performance index within 3 minutes after single training in an olfactory conditioning assay, indicating a defect in learning acquisition. The mutants show defects in 1 and 3 hour memory similar to the defects seen immediately after training.

Homozygotes have normal olfactory acuity in response to 4-methylcyclohexanol or 3-octanol.

Homozygous and heterozygous adults show no significant change in mushroom body morphology compared to wild-type controls.

Projection neurons are morphologically normal in homozygous adults.

Comments

Expression of PQBP1Scer\UAS.cWa under the control of Scer\GAL4GMR.PU restores rhabdomere structure and electroretinogram response in newly eclosed PQBP1PL00109 mutant flies.

Expression of PQBP1Scer\UAS.cTa under the control of Scer\GAL4elav.PLu rescues the shortened lifespan of PQBP1PL00109 flies.

Expression of PQBP1Scer\UAS.cTa under the control of Scer\GAL4PQBP1-PL00109 completely rescues the learning acquisition defects of PQBP1PL00109 homozygotes.

Experiments in which the temperature sensitive Scer\GAL80ts.αTub84B allele is used to limit expression of PQBP1Scer\UAS.cTa under the control of Scer\GAL4PQBP1-PL00109 to particular stages show that expression of PQBP1Scer\UAS.cTa during the adult stage is necessary to rescue the learning defects of PQBP1PL00109 homozygotes.
