  • Rice plants can inherit cold tolerance without DNA changes, as shown in a study published in Cell.
  • The study identifies epigenetic tweaks as the mechanism for heritable cold tolerance in rice plants.
  • Researchers found fewer chemical tags on the ACT1 gene in cold-tolerant rice plants, demonstrating causality.
  • The adaptation occurred over just a few generations, much faster than expected through natural selection.
  • Extensive genetic testing confirmed the changes were epigenetic, not due to DNA sequence mutations.
