a heat shock promoter drives expression of a Wee1 cDNA.
Wee1hs.PP partially rescues Wee1ES1/Df(2L)Dwee1-W05
Approximately 50% of embryos derived from weeES1/Df(2L)Dwee1-W05 females can be rescued to at least the cellularisation stage (cycle 14) by expression of weehs.PP. A wide phenotypic variation in the extent of resue is seen, ranging from mosaic embryos containing both cellularised and syncytial sectors to apparently normal late embryos and first instar larvae that are nonetheless unable to complete development.
