Oxidative stress resistance: A robust correlated response to selection in extended longevity lines of Drosophila melanogaster?

Stress resistance Is associated with longevity in Drosophila melanogaster a cid other model organisms used for genetic research. The present study test s for oxidative stress resistance in one set of lines selected for late-lif e reproduction and extended longevity. Both females and males from the sele cted lines were appreciably more resistant to oxidative stress than were fl ies from the control lines. A relative increase in oxidative stress resista nce is a correlated response to selection in this laboratory selection expe riment. Increased oxidative stress resistance appears to be a relatively ro bust correlated response to laboratory selection for late-life reproduction and extended longevity.
