UAS regulatory sequences drive expression of an inverted repeat.
Wild-type females crossed with males expressing guduJF01141 under the control of Scer\GAL4tub.PU lay a similar number of eggs as control females crossed with wild-type males. However, none of the eggs hatch.
The hatching rate of eggs laid by females expressing guduJF01141 under the control of Scer\GAL4tub.PU crossed with wild-type males is normal.
The testes of males expressing guduJF01141 under the control of Scer\GAL4tub.PU have normal onion-stage spermatids, and elongated spermatids are seen. However, the mutant testes contain spermatid bundles with little mobility, in contrast to the motile and individualised sperm seen in wild type. The individualisation complexes are disorganised and diffuse compared to wild type.
