Gamma radiation triggers epigenetic methylation pathways

This reasoning chain links gamma radiation exposure to changes in DNA methylation (DMRs), the context-specific nature of these changes, and their localization to stress-response genomic regions. It integrates dose rate and generational effects to explain how epigenetic modifications mediate Arabidopsis adaptation to multigenerational ionizing radiation.
