Deletion of approximately 500-700bp that deletes intron and maybe also exon sequences.
lethal (with Df(3L)XBB70)
Heterozygotes show abnormal temperature-preference behaviour; their avoidance index against low temperatures is less than 34% of wild type, while their avoidance index against high temperatures is normal.
Heterozygotes have normal locomotor activity at 25oC.
ple+t8 rescues mutant embryos to viable adults. Some adults die attempting to free themselves from the pupal case, the greatest lethality occurs during the pharate adult stage. Adults that do eclose are paler than their ple+ siblings and they appear weaker in their movements with a tendency to drown in the food medium. Rescued larvae are normal in their response to both light and NaCl.
Mechanical dechorionation and devitellinization of hemizygous and homozygous eggs leads to development of pharate larvae. These have complete lack of pigmentation of the cuticle, mouth hooks, spiracles and setae.
Ddc27, ple4 has cephalopharyngeal skeleton phenotype
Mutation leads to disruption of catecholamine synthesis without disrupting serotonin synthesis.
