UGA peanut researchers win accolades for international impact

By Merritt Melancon, Allison Floyd

Peanut researchers from the University of Georgia met with hundreds of peanut scientists from around the world earlier this week to discuss the international impact of peanut research and to recognize top researchers.

With a “Peanuts Around the World” theme, the annual meeting of the American Peanut Research and Education Society was held in Auburn, Alabama, featured presentations by the UGA-housed Feed the Future Peanut Innovation Lab demonstrating the benefits of research collaboration to science, industry and agriculture in the U.S. and countries around the world.

Among the team's well-attended sessions was a two-hour symposium titled “Synergies from U.S. Global Research Partnership,” which highlighted individual projects in the lab’s portfolio and how scientists in the U.S. and African partner countries are working to harness genetic diversity in the peanut. Such diversity will help farmers in partner nations, as well as in the U.S., adapt to pest and climate challenges today and for years to come.

Agricultural challenges don’t recognize geographic or political boundaries, and solutions have the potential to come from all parts of the world.

For example, resistance to tomato-spotted wilt virus in the U.S. comes from peanuts bought in a market in Brazil in 1952, explained David Bertioli, a professor in the UGA Institute for Plant Breeding, Genetics and Genomics and principal investigator of an innovation lab project incorporating wild alleles to improve West African peanut cultivars.

“When this type of transfer happens properly, everyone wins,” Bertioli said.

International treaties meant to thwart bad actors and protect biological resources have limited research in unintended, negative ways by slowing the exchange of germplasm to a trickle, which hurts global food security, he said.

Working to inventory and analyze the diversity of peanuts grown across Africa, a team of U.S. and African researchers are leveraging the recently sequenced peanut genome to create tools plant breeders can use to generate varieties with natural resistance to disease and other shocks.

Along with David Bertioli, UGA researchers Soraya Bertioli, Josh Clevenger and Peggy Ozias-Akins work on the U.S. side of these related Peanut Innovation Lab projects, while Daniel Fonceka of Senegal, David Okello in Uganda and plant breeders from seven other countries in Africa lead the work on that continent.

In recognition of the Bertiolis’ work to help improve peanut production worldwide, they were awarded the most prestigious awards of the conference, the American Peanut Council Peanut Research and Education Award.

According to the American Peanut Council, the Bertiolis’ unique but related research programs have focused on the wild relatives of peanuts. They work to unravel the collection of untapped genetic traits naturally occurring in the peanut ancestors and identifying the traits for use in breeding programs around the world to solve real-world limitations to peanut production.

For more than 15 years, they have worked to genetically characterize the relationships of the wild relatives of peanut with cultivated peanuts. Importantly, their work underpinned the effort to sequence the peanut genome by first focusing on the more tractable diploid, wild ancestors. Their research has led to a much deeper understanding of the relationship of the wild relatives to cultivated peanuts and our ability to move valuable traits from the wild into cultivated crops.
