UASp regulatory sequences drive expression of tam cDNA that has silent mutations in the 2074-2750 region to render it RNAi resistant to tamKK100485, tagged at the C-terminal with 3xTag:FLAG.
The failure to eliminate mitochondrial nucleoid and mtDNA during spermatid development characteristic for males expressing tamKK100485 under the control of Scer\GAL4bam.T:Hsim\VP16 can be fully rescued by co-expression of tamUASp.RR.Tag:FLAG.
