Radiation induces stress and transgenerational impacts in the cricket, Acheta domesticus

Purpose: Radiation exposure of crickets during their fourth juvenile molt inflicted ionizing radiation damage and altered growth rate, adult size at sexual maturity. High levels of ionizing radiation also impacted the subsequent generation, likely via heritable epigenetic mechanisms. Using radiation as a proxy for external stress, we aim to understand the transgenerational impacts of stress on non-irradiated offspring. Methods and materials: We …
