The transformer gene controls sexual development in Drosophila suzukii.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects, but also serves as a basis for developing genetic control strategies for pest species. In this study, we isolated the sex determination gene transformer (Dstra) from a global fruit pest, the spotted-wing Drosophila (Drosophila suzukii), and characterized its gene organization. By comparing the deduced protein sequence of Dstra with its orthologs from 22 species, we found that tra genes from Dipteran species are divergent. Our research demonstrated that Dstra undergoes sex-specific splicing, and we validated its developmental expression profile. We engineered a piggyBac-based transformation vector expressing the complete Dstra coding sequence under the control of the Tetracycline-Off system. Through germ-line transformation, we generated 4 independent transgenic lines, producing pseudo-females from chromosomal males in the absence of tetracycline. This observation indicated ectopic expression of Dstra, confirmed by the detection of female Dstra transcripts in transgenic males. The pseudo-females exhibited altered wing patterns, feminized abdomen, abnormal reproductive organs, and disrupted sexual behavior. Ectopic expression of Dstra affected the sex-specific splicing pattern of the downstream gene fruitless, but not doublesex. In conclusion, our study provides comprehensive genetic, morphological, and behavioral evidence that Dstra controls sexual development in D. suzukii. We discuss the potential applications of this research for genetic control strategies targeting Dstra or using its gene elements.
