Epigenetics: Conducting The Symphony Of Genetics

For all the hype, fear and misinformation that surrounds the application of gene editing, there is an equally powerful technology that offers much the same in potential benefit. This technology, epigenetics, is a natural process that has gone largely unremarked by consumers.

High-yielding plants that survive temperature swings may be our next weapon against climate change

Sally Mackenzie spent her childhood summers walking through the vast fields of bright, red, ripe tomato crops: They grow best in the heat of her home state of California. Yet recent seasons prove it can get too hot for a tomato.

Researchers graft tomato plants with epigenetically-modified rootstock

Progeny of novel combination is more vigorous and productive than parental plants. Novel grafted plants — consisting of rootstock epigenetically modified to “believe” it has been under stress — joined to an unmodified scion, or above-ground shoot, give rise to progeny that are more vigorous, productive, and resilient than the parental plants.

Plants pass on 'memory' of stress to some progeny, making them more resilient

By manipulating the expression of one gene, geneticists can induce a form of “stress memory” in plants that is inherited by some progeny, giving them the potential for more vigorous, hardy and productive growth, according to Penn State researchers, who suggest the discovery has significant implications for plant breeding.
