Lack of effect of acute acetaldehyde treatment on X chromosome segregation in Drosophila melanogaster females.
The effect of acute acetaldehyde treatments on X chromosome segregation was tested in germinal cells of Drosophila melanogaster females. The experiments were carried out using a test system where the nondisjunctional females (XXY) and only 1/4 of the expected regular progeny are viable. 24 h old virgin females were exposed for 60 min to 3, 4 and 5% acetaldehyde solutions by means of soaked tissue paper placed at the bottom of regular culture vials. After mating the females were brooded daily. Two additional experiments were performed with 0-2 h old and 4-5 day old virgin females using a 4% acetaldehyde solution. The results obtained show that acetaldehyde did not affect X chromosomal segregation in oocytes. This lack of effect could result from the highly efficient ADH-ALDH dependent detoxifying mechanism operating in Drosophila melanogaster.
