This competitive program provides funding for researchers in the college, enabling them to enhance the commercial potential of ongoing Penn State research and prepare them to translate their Penn State-owned intellectual property to the marketplace.

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.

Grafting with epigenetically-modified rootstock yields surprise

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 parent plants.

As climate change makes growing seasons less predictable, scientists dig into a novel approach to boosting crop resilience

Epigenetic modification of plants shows promise for enhancing food security — but we still have a lot to learn.

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.

Mackenzie Named Inaugural Director of Plant Institute

Sally Mackenzie sees a unique opportunity for Penn State to address complex global challenges in an unprecedented way.

Can plants get scared? Or help fight depression? New research suggests 'yes'

New studies show that plants react to threats much in the way that fear motivates people and that plants can reduce depression and lead to longer life spans.
