Stay ConnectedTalking Biotech is a weekly podcast that uncovers the stories, ideas and research of people at the frontier of biology and engineering.
Each episode explores how science and technology will transform agriculture, protect the environment, and feed 10 billion people by 2050.
Interviews are led by Dr. Kevin Folta, a professor of molecular biology and genomics.

Plant disease resistance is a complicated arms race between the plant and pathogens. Bacteria, viruses and fungi evolve in lock-step with plants, creating new ways to overcome new disease resistance strategies. Resistance to disease has a foundation in the gene-for-gene model, a model that hypothesizes that plants and pathogens have a molecular relationship with each other that mediates pathogenicity. Today’s podcast features Drs. Lida Derevnina and Chih-Hang Wu, postdoctoral researchers with Sophien Kamoun (@KamounLab) at the Sainsbury Laboratory (@TheSainsburyLab) in Norwich, England. They describe the new thinking of disease resistance as a number of complex layers that integrates many gene-for-gene interactions with other mechanisms in mediating plant defense. Hosted by Paul Vincelli (@pvincell).

Dr. David Just studies human behavior and how psychology ties in with economic decisions. His work at Cornell examines the interesting overlays that cause consumers to behave how they do. In this podcast we examine consumer decisions in food, including a discussion about soft drinks, ketchup, meat, and ingredients from genetically engineered crops. We also touch on the “GMO labeling” issue.

Alfatoxins are a significant threat to human health and world food security. They are naturally-occurring toxic compounds produced by the fungus Aspergillus flavus and other species. These fungi thrive on corn, peanuts, wheat, rice and other food staples, and grow well in stored food supplies. The compounds are potent carcinogens, and it is estimated that billions of people suffer from chronic exposure. Today’s guest is Dr. Peter Ojiambo from North Carolina State University. He describes the current state of the problem and solutions, ranging from biocontrols, cultural adjustments and even modern biotechnology techniques.

The 2016 World Food Prize went to a group that coordinated the breeding, promotion and distribution of the orange-fleshed sweet potato in Africa. One of person on the team was economist Dr. Jan Low. The sweet potato grows well in many parts of Africa. It is not the sweet potato known to westerners. It is white and dry, and more like bread than the well known Thanksgiving sweet potato. At the same time there is widespread vitamin A deficiency, especially among children. Could the orange sweet potato help solve a critical micronutrient deficiency? Dr. Low and her team introduced the orange fleshed sweet potato to Africa, breeding them against locally adapted varieties. The new potatoes were introduced with marketing campaigns, helping introduce new populations to this novel product. Soon, the orange fleshed sweet potato was aiding the diet, saving lives, and creating new entrepreneurial opportunities for African farmers and commerce.

When social scientists examined messaging in new media around GE crops, a few trends became apparent. Surprising evidence emerged that showed that the Russian Federation is actively participating in a campaign, here in the USA, to malign GE crops with a goal of influencing public opinion. In this week’s episode Dr. Shawn Dorius from Iowa State University talks about the recent findings. He describes a literal propaganda campaign designed for English-speaking countries. The apparent goal is to erode public trust in American agriculture, and influence opinion away from technology that Russia does not have. Hosted by Paul Vincelli (@pvincell).

Mark Lynas believed in his heart that he was doing the right thing. He was joining others in tearing out field trials of GE crops, and effectively arrested research and development around crop biotechnology. He participated in a movement that significantly shaped public opinion that influences policy to this day. But Mark is a scientific author, and when writing about climate change understood the need for rigorous evaluation of scientific evidence. When he applied the same thinking to GE crops, it was apparent that he was not following the evidence – and changed his mind. Mark treats the topic of plant biotech with refreshing nuance, sitting cleanly in the interface of sound science and responsible social application. His book details his journey, and is a refreshing primer for all of us that need to check ourselves for self delusion, and ensure that we are pursuing the truth in our discussions.

The race to determine the structure of DNA has a dark subtext that is frequently ignored when discussing this seminal discovery in biology. Competing groups at Cambridge and King’s College set their sights on resolving this important question. King’s College recruited a bright young x-ray crystalographer, a scientist that used energy to examine molecular structure. Her name was Dr. Rosalind Franklin. While teams in this old-boy’s network pushed forward, Franklin used her skills to generate data to answer the question. Her data would provide the information needed to determine the structure of DNA. However, she was not credited beyond a tiny footnote, and died at 37 never realizing how her data illuminated the discovery of DNA’s double-helical structure. The story is told by Dr. Mark Lawler of Queens University in Belfast, Northern Ireland.

Mexico is the center of origin for maize, and there is a substantial interest in protecting the genetic integrity of this limited resource. At the same time Mexico’s population is growing, and farmers potentially find utility in growing genetically-engineered corn, as resistance to insects and lower pesticide use are attractive traits. There is an intricate balance between feeding a population and ensuring farmer profit versus preservation of a genetic resource. In this week’s podcast Dr. Paul Vincelli (@pvincell) interviews Dr. Sol Ortiz Garcia, the Commission on Biosafety of Genetically Engineered Organisms. How much GE maize is cultivated in Mexico? Is it a threat? Is there evidence of transgene flow from imported feed? These are important questions, as the topic of genetic integrity of natural populations is a frequent area of discussion and debate.

The internet claims that the increases in celiac disease is rooted in modern wheat varieties, as human intervention in plant genetics must be the cause of human disorders. But what does the evidence tell us? In this week’s episode we’re joined by Dr. Senay Simsek from North Dakota State University. Dr. Simsek is a recognized chemist that specializes in wheat composition. Her recent paper in the journal Food Chemistry examines the levels of gluten in modern varieties and compares it to what was present in heritage varieties. The results show that associations between modern breeding and gluten sensitivity are not likely due to genetic improvement of wheat varieties.
Here is the link to the paper discussed.

And this the review that highlights efforts to reduce allergenicity.
