DNA repair efficiency and thermotolerance in Drosophila melanogaster from "Evolution Canyon".

The repair efficiency of four thermotolerant and four thermosensitive isofemale lines of Drosophila melanogaster originating from "Evolution Canyon" (Mt Carmel, Israel) was tested using 2-acetylaminofluorene (2-AAF) as mutagen. First, males of the standard laboratory line Canton S were treated with either 2-AAF solution or control solution. Then, females of the "Evolution Canyon" lines were crossed with treated (2-AAF or control solution) males and maintained at either 24 or 29 degrees C.
