Expression of an 0.886kb EcoRI fragment of Btau\SOD cDNA, coding region and 87bp of 5' untranslated sequence including the 5bp Kozak consensus sequence, is driven by an EcoRI-SalI Act5C promoter.
Expression of P{bSOD} restores Sodn1 male fertility and resistance to paraquat to apparently normal levels. Adult life is restored to only 30% of normal and resistance to hyperoxia is 90% of that found in control flies.
