摘要

在25℃条件下，研究了雄性拟果蝇和雄性黑腹果蝇mariner转座因子的体细胞运动对寿命的影响。在D. simulans中，转座子的移动显著降低了寿命，而在D. melanogaster中，转座子的移动与寿命没有相关性。D. Simulans的研究结果支持了DNA元件运动引起的体细胞遗传损伤可缩短寿命的假设。

Somatic movement of the manner transposable element and lifespan of Drosophila species

The effect of somatic movement of the mariner transposable element on lifespan was measured in Drosophila simulans and Drosophila melanogaster males at 25°C. In D. simulans this movement significantly decreased lifespan, whereas in D. melanogaster no correlation between transposon movement and lifespan was found. The results in D. Simulans support the hypothesis that somatic genetic damage induced by DNA element movement can reduce lifespan.
