- P_element abstract "A P element is a transposon that is present specifically in the fruit fly Drosophila melanogaster and is used widely for mutagenesis and the creation of genetically modified flies used for genetic research. The P element gives rise to a phenotype known as hybrid dysgenesis.P elements were discovered in the 1970s when laboratory strains used since 1905 were compared to wild type flies (i.e. found in nature). It seemed that these P elements had swept through all wild type populations of D. melanogaster subsequent to the isolation of the laboratory strains, which did not contain P elements.The P element encodes for the protein P transposase and is flanked by terminal inverted repeats which are important for its mobility. Unlike laboratory strain females, wild type females are thought to express an inhibitor to P transposase function. This inhibitor reduces the disruption to the genome caused by the P elements, allowing fertile progeny. Evidence for this comes from crosses of laboratory females (which lack P transposase inhibitor) with wild type males (which have P elements). In the absence of the inhibitor, the P elements can proliferate throughout the genome, disrupting many genes and killing progeny.".
