In this episode of GermiNation, we bring together two influential voices in the global seed industry. We sit down with Andy LaVigne, President and CEO of the American Seed Trade Association (ASTA), and Diego Risso, Executive Director of the Seed Association of the Americas, for conversations on leadership, collaboration, and the future of seed systems. From policy and innovation to workforce development and international trade, this episode explores how seed associations are working across borders to strengthen agriculture and ensure farmers have access to high-quality seed.

On this episode of GermiNation, we’re joined by a scientist working at the forefront of molecular seed diagnostics: Jeffrey Williams, research scientist at Iowa State University’s Seed Science Center.

Jeffrey’s background spans deep expertise in microbiology and hands-on experience in plant diagnostics, sharpened during his years at Corteva’s Plant Diagnostic Clinic. Now at the Seed Science Center, he plays a critical role in advancing molecular seed quality testing—especially in support of the USDA National Seed Health System, which ensures U.S. seed exports meet strict international phytosanitary standards.

His work fuels global seed trade, strengthens agricultural sustainability, and reinforces the trust farmers place in the seed they plant.

In this episode, we explore Jeffrey’s career path, the molecular puzzles behind seed health, and the curiosity and commitment that drive his research every day.

In this episode of GermiNation, We explore the seeds that connect us - we’re taking you to the Seed Savers Exchange annual conference and 50th anniversary celebration for conversations with leaders working to preserve and protect seed diversity:

We talk to Bonnetta Adeeb – Founding member of Ujamaa Cooperative Farming Alliance and Ujamaa Seeds, on the importance of African Indigenous seeds. www.ujammaseeds.com

Followed by Nicolas Enjalbert – CEO of SeedLinked, discussing groundbreaking research with USDA NIFA, Seed Savers Exchange, and thousands of farmers. www.seedlinked.com

We finish the show with Linda Black Elk, an American Indigenous seed expert, sharing stories and wisdom about traditional foodways. www.natifs.org

From ancestral knowledge to cutting-edge science, this episode celebrates the seeds that connect us all.
