The lineage of the novel compound is more vigorous and productive than the parent plant.
Novel grafted plants – modified from rootstock to what is supposed to be – attached to an improved plan, or shoot on the ground above, give birth to offspring that are more vigorous, productive and resilient than parent plants.
The team of researchers has made the astonishing discovery that they conducted large-scale field trials with tomato plants in three widely divided locations over several pavilions of the plant. They argue that the discovery, which Penn State, this University of Florida And a small start-up company in Nebraska has the main implications for plant breeding.

Because the technique involves epigenetics – altering the expression of existing genes and not introducing new genetic material from other plants – crops grown using this technique can lead to controversy involving genetically modified organisms and food. This is the hope of Sally McKenzie, leader of the research team at the Aberley College of Science in Pennsylvania, a professor of plant science at the Agricultural College of Agricultural Sciences, and a professor of biology at the Aberley College of Science.

“Although we’ve done this with tomatoes, it can be done with any plant.” “We think this study represents a major breakthrough in showing the potential for epigenetic breeding for crops. And later, it will have a big impact on trees and forests that are facing climate change. ”
In light of previous research by Mackenzie’s research team at Penn State, the rootstock came from a tomato plant in which researchers manipulated the expression of a gene called MSH1 to induce “stress memory”. That memory is inherited by some lineage, giving them the potential for more vigorous, fearless and productive growth.
MSH1G put researchers on a path to controlling a wide array of plant elastic networks, explained Lloyd and Dottie Haq Chair for Functional Genomics and Man Kanzi, director of the plant organization at Penn State. “When a plant experiences stress such as drought or prolonged extreme heat, it has the ability to quickly adapt to its environment so that it can become a phenotypic ‘plastic’ – or flexible.” And, it turns out, he remembers. Is. ‘”
The discovery that those “remembering” traits passed from the root to the top of the plant from the graft – published today (October 22, 2020) Nature Communications – It is very important that Mackenzie pointed out. The grafted tomato plants involved in the research produce seeds that resulted in, on average, 35% more productive – a stunning result, she noted. And that growth momentum has been in research for more than five generations.

Plants are also hardy, according to Mackenzie. Russell E. of Penn State in 2018. During the study component of the Larsen Agricultural Research Center, hurricanes rained more than 7 inches in August, flooding tomato fields. Pulled water erased plants that were part of other research tests. However, the plants that were the offspring of grafted plants with epigenetically manipulated rootstock largely survived – and then they prospered.
The lineage of grafted plants also maintained excellent survival in other field trials conducted in California and Florida.
The research is the first true demonstration of an agro-cultured proper epigenetic breeding method, Mackenzie said, adding that the technology is ready for immediate adjustment.
“Whatever we are doing, any plant in agriculture can breed, and now we are showing on a large scale that it has agricultural value. It’s ready to go – a breeder can read about it and implement a system to improve its variations, “Mackenzie said.
