Detailed Description

Statement

Reference

dnc¹/dnc^ML adults show a significant reduction in performance index in an aversive olfactory learning assay compared to control flies.

(Nagarkar-Jaiswal et al., 2015)

dnc^ML homozygous and dnc^M14/dnc^ML heterozygous mutants exhibit an increase in the number of naturally occurring synaptopods at the type II endings. This increase is eliminated in a Dp(1;2)51b background.

(Koon et al., 2011)

Mutant flies show a significant reduction in the number of rest hours per 24 hours compared to controls.

(Hendricks et al., 2001)

Some dnc^ML flies are arrhythmic with respect to locomotor activity (only 63.16% are rhythmic).

(Williams et al., 2001)

Flies have a low learning score (0.15) in an olfactory classical conditioning paradigm. Homozygous females are sterile. Fertility is restored to approximately 50% if dnc^hs.PD is expressed using heat shock.

(Dauwalder and Davis, 1995)

The point of maximal phase delay of the light induced phase response curve (PRC) differs significantly from that of wild type and the circadian period is significantly shorter.

(Levine et al., 1994)

Flies transformed with the P{dnc^hs.P} or P{rat\dnc^hs.P} construct display increased learning scores. Reduced learning and memory.

Genetic Interactions

Statement

Reference

Trans-heterozygotes of Fmr1³ and dnc^ML do not exhibit learning deficits.

(Kanellopoulos et al., 2012)

The low learning score phenotype is completely rescued by Rat\RD1^hs.PD expressed using heat shock.

Complementation and Rescue Data

Rescued by

dnc^ML/dnc^M14 is rescued by dnc^UAS.cCa/Scer\GAL4^Tdc2.PC

(Koon et al., 2011)

dnc^ML is rescued by dnc^UAS.cCa/Scer\GAL4^Tdc2.PC

(Koon et al., 2011)

Comments

Expression of dnc^Scer\UAS.cCa exclusively in octopaminergic neurons under the control of Scer\GAL4^Tdc2.PC rescues the increase in synaptopods at neuromuscular junction type II endings seen in dnc^ML homozygous and dnc^M14/dnc^ML heterozygous mutants.

(Koon et al., 2011)

The low learning score phenotype is partially rescued by dnc^hs.PD expressed using heat shock. Fertility is restored to approximately 50% if dnc^hs.PD is expressed using heat shock.

(Dauwalder and Davis, 1995)

A partial rescue is seen after induction of dnc^hs.P. A significant increase in the initial learning score is seen. Heat shock pulses four days after hatching partly rescues female fertility.
