Commission fosters quest for allergen-free peanuts

Georgia Commissioner of Agriculture Tommy Irvin loves to eat peanut butter and graham crackers. But his grandson has a peanut allergy. So when all of Irvin’s 14 grandchildren come to visit, he makes sure none comes in contact with peanuts.

That’s one reason why he presented a $100,000 check from the Georgia Seed Development Commission to the University of Georgia College of Agricultural and Environmental Sciences. The money will be used to help researchers there develop an allergen-free peanut.

“It’s very challenging to try to eliminate allergens from peanuts,” said Peggy Ozias-Akins, a CAES plant geneticist and horticulture professor based in Tifton. “So far, we’ve been able to greatly reduce one of the proteins identified as a major allergen in peanuts with no obvious detrimental effect to seed viability and development.”

But a modified peanut with the reduced protein still has allergenic properties. She believes the protein may have to be completely eliminated or other proteins not yet researched play a role in peanut allergy troubles.

Steven Knapp, a CAES crop and soil sciences professor based in Athens, is working to build genomics resources to improve peanuts using molecular breeding. He investigates a broad range of economically important peanut traits, such as disease resistance.

Both researchers are working to develop an allergen-free peanut. It takes more than a year to produce a transgenic peanut.

“We are building the infrastructure for applying genomic solutions to breeding problems in peanuts,” he said. “These tools can be applied to a wide range of traits.”

Peanuts are in many foods served in schools and other public places where children with peanut allergies can be exposed to them. Peanuts are among the top 10 agricultural commodities in Georgia with an off-the-farm value of $321 million annually. It helps many farmers put food on their own tables and drives rural economies in certain parts of the state.

“I think it’s a wise investment for the commission, the university and the peanut industry,” Irvin said. “We can’t afford to lose any of our market . . . Wouldn’t it be great if we came up with an allergy-free peanut?”

The holiday season can be a time of anticipation and joy, but balancing multiple commitments and personalities across families and friends can be a source of stress for hosts and visitors alike. Like preparing parts of the meal ahead of time to spend more of the holiday with guests, taking time ahead of the day to set expectations can go a long way to ensuring enjoyable gatherings, said Ted Futris, University of Georgia Cooperative Extension specialist and professor of human development and family science in the College of Family and Consumer Sciences.

The University of Georgia College of Agricultural and Environmental Sciences welcomed its fourth cohort of students chosen for the CAES Rural Scholars Program this fall just weeks after celebrating the program's first graduation. Georgia Orman, one of four inaugural Rural Scholars in CAES, graduated in May with a bachelor’s degree in agricultural education. The new scholars for 2024, all from Georgia, are Ela Ash of Ocilla, Lauren E. Coley of Cochran, Amelia Housley of Canon, and London O’Steen of Ambrose.

The women and stress behind rural farming in America 11/19/24 Leigh Hataway
Recent research from the University of Georgia suggests the unique stresses from farm life may be taking a toll on one of the pillars of the families that make your dinners possible: the women who keep farming families running. “If we don’t control our food sources, we don’t control our health and safety,” said Anna Scheyett, lead author of the study and a professor in UGA’s School of Social Work. “It’s a matter of national security that farmers survive in the United States. And one of the big factors in helping farms survive is women.”

Wheat breeders spend years meticulously crossing varieties to coax the best traits out of each species, carefully propagating plant varieties that are healthier, heartier and better suited for the environments where they are grown. Professional brewmasters are equally painstaking when choosing the components that will give their beers a specific flavor profile.
