A model system for analyzing somatic mutations in Drosophila melanogaster

Article metrics

Abstract

Presently there are no good assays for comparing somatic mutation frequencies and spectra between different vertebrate and invertebrate organisms. Here we describe a new lacZ mutation reporter system in D. melanogaster, which complements existing systems in the mouse. The results obtained with the new model indicate two-to threefold higher frequencies of spontaneous mutations than in the mouse, with most of the mutations characterized as large genome rearrangements.

J.V. conceived, designed and supervised the study (initially with M.E.T.D.), obtained the funding and took the primary role in writing the manuscript. A.M.G. designed and performed most of the experiments, with A.D., assisted by R.B. and E.P. M.L. generated the transgenic flies (assisted by L.C.) and supervised the final experiments. R.B.C. provided statistical support.
