Maternal age effects on offspring longevity in Drosophila melanogaster

Maternal effects may play a crucial role in the evolution of aging. We conducted several experiments with different strains of the fruit fly, Drosophila melanogaster, to explore how maternal age, paternal age, and parental mating history affect offspring aging. We found that maternal age, parental mating history, and to a lesser extent, paternal age effects can have a profound influence on the survival, mortality intercept and death rate of offspring. In independent experiments we found that the effects of parental age and mating are different for different strains. These results suggest that maternal effects may play a crucial role in both the mechanisms and evolution of aging.

Effect of storage conditions on phenolic compounds and antioxidant activity of blueberry extract and the effect of anthocyanins from selected cultivars of Georgia-grown blueberries on apoptosis and phase-ii enzymes Srivastava, Anita (uga, 2006-12)Blueberry (Vaccinium corymbosum) of the family Ericuceae is reported to have high antioxidant activity compared to other fruits and vegetables. This is highly correlated with the anthocyanins and total polyphenolic content. ...
