Intergenerational and dose-rate effects on DMR induction

InferenceChain·nasa

This reasoning chain explains that DMR induction after gamma irradiation in Arabidopsis depends on both prior generational exposure (priming) and on the dose rate, with evidence showing a generation-dependent and threshold-like response. Local methylation changes are more pronounced in later generations and are stronger at lower doses, while highest dose rates trigger a different, non-DMR response mechanism.
