Space environment induces heritable, epigenetic, and phenotypic changes in plants

InferenceChain·nasa

This chain explains how exposure to space and microgravity acts as a stressor, leading to genetic mutations, stable epigenetic marks (especially DNA methylation), as well as gene expression, physiological, and morphological changes in plants across multiple species. These heritable and non-heritable outcomes support the development of novel plant varieties with altered yield, phenotype, resistance, and metabolite profile.
