RESEARCH-PGR: A Genome-level Approach to Balancing the Vitamin Content of Maize Grain

This collaborative research project is directed at identifying a subset of the ~40,000 genes in the corn genome that work together to determine the levels of five essential and limiting dietary vitamins in kernels: vitamin E and the four B vitamins, B1 (thiamin), B2 (riboflavin), B3 (niacin) and B6 (pyridoxine). By combining approaches similar to those used in the Human Genome project, the researchers will identify alleles, special variations in these "vitamin" genes, and learn how to put them together to generate high amounts of vitamins in corn kernels.

Thomas Lübberstedt is pushing the boundaries of genetics and its use in developing tools and methods to make plant breeding more efficient.

His work is leading to improved virus resistance and more sustainable agricultural systems around the world. The Frey Chair in Agronomy and Director of the Raymond F. Baker Center for Plant Breeding, Lübberstedt recently received the College of Agriculture and Life Sciences’ Outstanding Achievement in Research Award.

International Credentials
Lübberstedt grew up on a horticultural farm in Germany and earned his degrees from the universities of Munich and Hohenheim. He spent several years working in Germany, and then Denmark, before coming to Iowa State in 2007 to take an endowed chair position.

Leandro Tonello Zuffo, a PhD student visiting from Federal University of Viçosa in Brazil with an interest in agronomy arrived to Iowa State University on August 30, 2018 and is conducting research with Dr. Thomas Lubberstedt. Leandro’s research focus is on the application of tools and methods provided by genome analysis to understand the composition of complex traits and phenomena, to determine and exploit genetic diversity in elite and exotic germplasm and apply this knowledge to plant breeding.

AMES, Iowa – The American Association for the Advancement of Science (AAAS) is honoring seven Iowa State University researchers for their work in agriculture, biological sciences, chemistry and engineering, including our Dr. Jianming Yu.

The seven are among 416 researchers from around the world who make up this year’s class of AAAS Fellows, the association announced today. The new fellows are being recognized “because of their efforts toward advancing science applications that are deemed scientifically or socially distinguished.” Dr. Yu joins the limited company of only 40 other faculty at Iowa State University as a AAAS Fellow.

Honors students pursue individualized programs designed to enrich their educational experiences. As a part of their program, each Honors student plans, develops and completes an individual project. The results of those efforts were put on display at the Spring 2018 poster presentation of Honors projects held April 25. Participating students from Agronomy included:

Savanah Jones: Stress tolerance gene identification in Arabidopsis

Brittany Kirsch: Performance of a small, field-scale wetland

Samantha Reicks: Sulfur fertility in soybeans

Aimee Schulz: Inbreeding depression in wild maize populations subject to habitat degradation in southwest Mexico
