Genetic and environmental modulation of the epigenetic control of transposition shapes the evolutionary potential of Arabidopsis thaliana

How species can adapt to abrupt environmental changes, particularly in the absence of standing genetic variation, is poorly understood and a pressing question in the face of ongoing climate change.

Here we leveraged multi-omics and bio-climatic data available for >1,000 wild A. thaliana accessions to show that transposable element (TE) mobilization is a major generator of genetic variation in A. thaliana that is finely modulated by genetic and environmental factors. Our findings and modeling indicate that TEs may be essential genomic players in the demise or rescue of native populations in times of climate crises.
