Developing Diverse Germplasmand Student Skill Sets to Address Needs in the Food Industry. M. Campbell, Truman State University, Truman State University, Annual GEM Cooperator meeting, ASTA, Dec. , Chicago, IL
Truman State University Mandated by the state of Missouri to serve as its only highly selective public Liberal Arts and Sciences University. Goals of University - Focus: undergraduates - To ‘Liberally’ Educate - Provide students an opportunity to engage in research.
UW-Madison (corn silage quality) NDSU (short season) Cornell (Plant Pathology) USDA Ames Iowa (ISU) Yield – ‘agronomics’ USDA Raleigh NC (NC-state) Yield – ‘agronomics’ Texas A&M (Drought resistance) Truman Provides students opportunity to practice applied genetic Truman State University (Food/industrial starch Development) USDA Univ. Missouri- (Genomics)
Truman Agriculture program: -One of 25 state universities with agriculture programs -Small ag. programs collectively graduate more majors than our ‘Flagship Land-grant’ school State Funding Faculty Entering Freshman Corporate Funding – out of state- 1996 - 2012
Other Challenges : • Varied levels of a basic understanding of sciences among student and faculty. • Healthy skepticism vs. general mistrust of industry and new technologies • Conventional plant breeding lumped with GMO’s
Hybrids replaced local varieties. USDA scientists rushed to collect and preserve germplasm. Your grandparents were plant breeders!!! Perkins yellow dentPI 269744 Accession was collected -1960. Missouri, US.Locality: From Perkins family in Adair County who have grown it for years
Resistant starch, the last novelty on that list of ingredients, has the corn refiners particularly excited today. They've figured out how to tease a new starch from corn that is virtually indigestible. You would not think this as a particularly good thing for a food to be, unless of course your goal is to somehow get around the biological limit on how much each of us can eat in a year. Since the body can't break down resistant starch, it slips through the digestive track without ever turning into calories of glucose -- a particular boon, we're told, for diabetics. When fake sugars and fake fats are joined by fake starches, the food industry will at long last have overcome the dilemma of the fixed stomach: whole meals you can eat as often or as much of as you like, since this food will leave no trace. Meet the ultimate -- the utterly elastic! -- industrial eater

‘The addition of a resistant starch to oral rehydration solution reduces fecal fluid loss and shortens the duration of diarrhea in adolescents and adults with cholera. ‘
Hypoglycemia • low blood sugar, is the most common adverse event associated with insulin therapy. • Excess insulin in causes large amounts of glucose to be taken up by liver and too little glucose to be released later. • Especially a problem with children at night. • Slow release starch theoropy for Nocturnal hypoglycemia Hepatocyte cell

Presence of an active plant breeding program educates students and faculty of all majors. • Financial support helps to leverage further funding. • Provides relevance to science: food security, economic development, awareness of genetic resources as a non renewable resource

History leasons: Embraced by the world, corn became the real gold Columbus discovered.
Corn is a starch crop • 75% starch • High yielding, stores well, energy dense • Improved food security • Shift in Diet: Enriched with carbohydrate. • Cost: Compromised health
