Grafting-Induced Epigenetic Changes Persist Across Generations in Solanum lycopersicum
Volkov A, Ishibashi T, Green S
Summary
9.3/10Grafting tomatoes onto salt-tolerant rootstock creates heritable DNA changes lasting 3+ generations, opening a non-GMO path to crop resilience.
Key Findings
Epigenetic changes persist 3 generations
Methylation overlaps salt-stress genes
Non-transgenic heritable improvement
Original Abstract
DNA methylation patterns acquired through grafting onto salt-tolerant rootstock persisted for 3 generations in tomato scions without continued grafting. Differentially methylated regions overlapped with salt-stress response genes, suggesting grafting as a tool for heritable epigenetic crop improvement.
Tomato
The tomato is a plant whose fruit is an edible berry that is eaten as a vegetable. The tomato is a member of the nightshade family that includes tobacco, potato, and chili peppers. It originated from western South America, and may have been domesticated there, in Mexico, or in Central America. Th...
