Putative point mutation.
GldP4l/Gldn1 females mated to virgin GldE1L/Df(3R)dsx2M males use stored sperm at a slower rate over a longer period compared with wild-type females mated to virgin GldE1L/Df(3R)dsx2M males.
The non-eclosion lethal phenotype of D.melanogaster Gldn1/GldP4l flies is fully complemented by Dpse\Gld+t15.65.
P element mediated transformation of a wild type copy of Gld rescued the non-eclosion mutant phenotype.
Pharate adults attempt to eclose but cannot break the operculum seams, after days of trying individuals die with their heads jammed into the anterior puparium. Excision of the anterior puparium before stage P15 will rescue virtually all flies. Rescued adults are fully viable and fertile.
1% wild-type enzyme activity in pupae and adult males.
