Direct determination of the influence of extreme temperature on transposition and structural mutation rates of Drosophila melanogaster mobile elements.
Two sets of mutation accumulation lines, one reared at 28 degrees C and the other at 24 degrees C, were compared for their transposition and rearrangement rates of eleven transposable element families. The changes affecting mobile elements were analysed by the Southern technique and in situ hybridization. No differences were found between treated and control lines. The role of the host genotype in transposition control and the significance of structural mutations in transposable element dynamics are discussed.
