UAS regulatory sequences drive expression of a short inverted repeat.
Females heterozygous for hopGL00305 and MTD-Gal4 (consists of Scer\GAL4otu.T:Hsim\VP16, Scer\GAL4nos.PG and Scer\GAL4nos.UTR.T:Hsim\VP16) crossed to hopGL00305 males results in: 0% hatching; egg/embryonic phenotype: hop segmentation defects; maternal effect.
