title: Induction of somatic and male crossing-over by bleomycin in Drosophila melanogaster.
abstract: Bleomycin (BLM) is well known as an antibiotic as well as for its antineoplastic activity. A clinical preparation of BLM was tested for its recombinogenicity in a higher eukaryotic organism, Drosophila melanogaster. Feeding of the F1 larvae on a medium with BLM increased somatic crossing-over spots on female tergites and induced recombination in male germ cells. However, nonlinear dose-response curves were obtained. Malformed tergites were also observed in females treated with BLM.
