Fmr1Δ50M, me31BΔ2 double heterozygotes exhibit a complete block of the long-term habituation (LTH) normally seen when flies are exposed to either ethyl butyrate (EB) or CO[[2]]] for 4 days. LTH appears normal in either heterozygote alone. This loss of EB-evoked LTH is restored by expression of Fmr1+t14. Short term habituation following one hour exposure to EB appears normal.

Fmr1Δ50M, AGO1k08121 double heterozygotes exhibit a complete block of the long-term habituation (LTH) normally seen when flies are exposed to either ethyl butyrate (EB) or CO[[2]]] for 4 days. LTH appears normal in either heterozygote alone. This loss of EB-evoked LTH is restored by expression of Fmr1+t14. Short term habituation following one hour exposure to EB appears normal.

Fmr13, Atx2X1 double heterozygotes exhibit a complete block of the long-term habituation (LTH) normally seen when flies are exposed to either ethyl butyrate (EB) or CO[[2]]] for 4 days. LTH appears normal in either heterozygote alone. This loss of EB-evoked LTH is restored by expression of either Atx2+t10.4 or Fmr1+t14. Short term habituation following one hour exposure to EB appears normal.

rin2 Fmr1Δ113M double mutant eyes, generated by eyFLP/FRT-mediated mitotic recombination, show an increase in ommatidial number under normal food conditions. This phenotype is rescued to a rin2 like phenotype by inclusion of Fmr1+t14.

The presence of four copies of Fmr1+t14 does not affect the Adar5G1 mutant phenotype with respect to type 1s and type 1b synaptic boutons, primary branch length and the number of synaptic branches.

A Adar5G1 heterozygous background in flies expressing four copies of Fmr1+t14 does neither suppress nor enhance the Fmr1+t14 phenotype.

The courtship behavior of 5-day-old Fmr13/+;PsnB3/+ double heterozygous males is severely impaired compared to either of the single heterozygotes that display normal courtship. This defect in naive courtship behavior can be rescued by combination with Fmr1+t14 allele.

Comments

Expression of Fmr1+t14 rescues the long term habituation (LTH) defects seen in Fmr13 mutant flies following exposure to either ethyl butyrate (EB) or CO[[2]]] for 4 days.

Expression of Fmr1+t14 rescues the learning and memory phenotype of Fmr13 mutants.

Expression of Fmr1+t14 strongly diminishes PDF-TRI neuron retention in Fmr1Δ50M mutants.

Fmr1+t14 (but not Fmr1FS) rescues locomotor defects and excessive grooming behavior at all ages (day 5, 15, 25, 35) in Fmr13/Fmr1Δ83M flies; courtship behavior defects at day 15 are also rescued by Fmr1+t14 but not Fmr1FS.

Fmr1+t14 rescues the midline crossing phenotype of mushroom body β-lobe axons that is seen in Fmr13 adults.

Fmr1+t14 rescues the increased number of boutons at the neuromuscular junction that is seen in homozygous Fmr13 larvae.

Fmr1+t14 almost completely rescues the loss of rhythmic locomotion activity which is seen in Fmr13 flies under constant darkness conditions.

Fmr1+t14 rescues the reduction in naive courtship activity seen in Fmr13 males and also rescues the defects in immediate recall and short-term memory after training, so that the rescued males show a reduction in courtship index at 0-2 and 60 minutes after training when placed with a receptive female.

The presence of Fmr1+t14 rescues the long-term memory defect associated with Fmr13 or Fmr1B155 homozygotes and Fmr13/Fmr1B155 transheterozygotes.

Fmr1+t14 rescues oogenesis phenotypes seen in Fmr13 homozygotes.

The defective immediate recall as well and short-term memory characteristic for Fmr13 mutant males is restored by combination with a single copy of the Fmr1+t14 transgene.

The presence of a single copy of Fmr1+t14 to Fmr13/Fmr1Δ83M or Fmr13/Fmr1Δ113M transheterozygotes greatly reduces the penetrance and expressivity of the β-lobe midline-crossing phenotype.

Fmr1+t14 rescues the crawling pattern defects of Fmr13/Fmr14.L wandering larvae.

Rescues the dendritic defects seen in Fmr14.L.

Rescues rhythmicity and courtship defects of Fmr13.
