Genome Editing: Foundations and Applications

Ames, Iowa – April 9 - 11, 2015

The symposium on Genome Editing: Foundations and Applications will be held at the Iowa State University Alumni Center from the afternoon of April 9 through the morning of April 11. The symposium will bring together leaders who are developing genome editing resources and tools and applying them in a wide variety of organisms. The main focus will be on the foundations and applications of TALEN and CRISPR/cas technologies in crop plant species. Topics covered in the symposium will range from the biological roles of TAL effectors and CRISPR/cas systems in their native contexts, proof-of-concept experiments, and successful applications of the technologies. The symposium is hosted by the ISU Crop Bioengineering Consortium, which seeks to address the urgent, grand challenge to provide sufficient food, feed, biofuels and biorenewable chemicals for the world's burgeoning population, through basic and applied research to enable the bioengineering of valuable traits in a variety of crops.

Steven Whitham

Iowa State University
Steven Whitham

Our research is centered on an interest in the molecular mechanisms that underlie viral and fungal pathogenicity as well as plant defense against these organisms. Our research projects involve studies the important row crop plants, soybean and corn, and we also utilize model host plants such as Arabidopsis thaliana and Nicotiana benthamiana. We use functional genomics approaches to study the molecular changes that occur in susceptible and resistant genotypes of crop and model plant species. The plant and pathogen genes identified in these studies are providing insight into ways in which successful pathogens interact with and manipulate their hosts and by which plants deploy defense mechanisms. The three major research areas are aimed at 1) identifying genes that determine the outcome of host-virus interactions, 2) developing and applying tools based on viral vectors to assess gene function in crop plants, and 3) the molecular interactions of soybean and soybean rust (Phakopsora pachyrhizi).
