Construct: The Dmau\mariner\T ORF from the nonautonomous M{peach} element is expressed under the dual control of an Hsp70 promoter and the M{peach} promoter.
Five out of seven insertions of P{hsp70:peach} result in a statistically significant reduction in the rate of germline excision of M{peach} from P{M{peach}wpch} caused by P{hsp70:Mos1} (tested in D.melanogaster).
