Detailed Description
Statement
Reference

Mutant larvae are resistant to the juvenile hormone agonist pyriproxyfen compared to wild type.

Mutant females show reduced fecundity: they begin ovipositing at 4.6 days after eclosion (in contrast to 3.0 days for wild-type females) and after 30 days, the total number of eggs laid by a single mutant female is only 65% that of wild type. The hatching rate of the mutant eggs is only 88%.

gce2.5k mutants expressing MetGD4384 under the control of Scer\GAL4Act5C.PI exhibit nearly 100% pupal lethality.

gce2.5k mutants expressing Scer\GAL4phm.PO exhibit a developmental delay as compared to controls.

Met27, gce2.5k double mutant females (crossed to control males) show 25.9% pupal lethality; this lethality is fully rescued upon expression of gce+tCH321-09E09, but only partially rescued upon expression of Met+tCH321-28O05.

Onset of metamorphosis (larval wandering stage) is delayed approximately 12 hours compared to wild type in Met27 gce2.5k double mutant larvae. Double mutant larvae and early pupae have a reduced body size compared to controls. The double mutants fail to undergo head eversion and die approximately 24 hours after pupariation. Fat body cells in the double mutants undergo precocious and enhanced programmed cell death compared to wild-type fat body cells.

Comments

The lethality of Met27 gce2.5k double mutants is fully rescued by a single copy of Met+t5.7 or by expression of gceScer\UAS.cBa under the control of Scer\GAL4arm.PS.
