Summary:
- Plants can "remember" past environmental stresses and adapt to them, thanks to a process called epigenetics.
- Epigenetics refers to changes in gene expression that don't involve changes to the DNA sequence itself. These changes can be passed down to future generations of plants.
- By understanding epigenetics, scientists are working to develop crop plants that are more resilient to environmental challenges like drought, pests, and diseases, helping to ensure food security in the face of climate change.
