Stress resistance is associated with longevity in Drosophila melanogaster

and other model organisms used for ge-netic research. The present study tests for oxidative stress resistance in one set of lines selected for late-life repro-duction and extended longevity. Both females and males from the selected lines were appreciably more resistant to oxidative stress than were flies from the control lines. A relative increase in oxidative stress resistance is a corre-lated response to selection in this laboratory selection experiment. Increased oxidative stress resistance appears to be a relatively robust correlated response to laboratory selection for late-life reproduction and extended longevity.
