Steven J. Clough
Assistant Professor of Genetics
and Molecular Biology of Plant-Microbe Interactions
USDA-ARS Research Geneticist
Although I am mostly known for developing the ‘floral dip’ protocol for transforming Arabidopsis, the main goal of my lab is to identify genes and small RNAs playing a role in defense to pathogens. My lab is using high throughput gene expression and sequencing analyses to identify these defense genes, especially in soybean, by monitoring expression during early plant-pathogen interactions. Having completed a variety of expression studies involving bacteria, fungi, aphids, herbicides and symbionts, we then compare these expression patterns using a web-based database that my lab developed. The identified defense-gene candidates and small RNAs are being verified by sequence comparison to mapped defense loci as well as by molecular methods in both soybean and Arabidopsis.

Brian Diers
Professor of Soybean Breeding & Genetics
My main research interest is focused on developing improved soybean germplasm through identifying and using genes from the soybean germplasm collection. These efforts couple conventional breeding with the mapping of these new genes using molecular markers. A major focus of these efforts is disease, nematode, and insect resistance. In addition to these efforts, my program is engaged in developing soybean varieties for niche markets.

Michael E. Gray
Professor of Agricultural Entomology
Co-Director North Central Region IPM Center
The main thrust of my research program has been to improve our understanding of the biology, ecology, and management of the western corn rootworm. This insect is the most important economic pest of corn in North America. Since the early 1990s, it has also presented challenges for producers in many countries throughout Europe. Cooperation with corn breeders is essential in improving the selection of corn hybrids that have greater tolerance or resistance to corn rootworm damage while maintaining competitive yields. In cooperation with Dr. Kevin Steffey, I also am responsible for the evaluation of transgenic hybrids targeted at corn rootworms and other pests such as the European corn borer.

Stephen Long
Professor
My research program has three main foci: 1) increasing crop yields by systems and synthetic engineering of more efficient photosynthesis into crops (funded by the Gates Foundation); 2) analyzing the physiological and molecular factors determining chilling tolerance in corn and Miscanthus, together with the development and application of phenotypic screens of tolerance; and 3) deployment of computational tools for guiding engineering and breeding of more resource use efficient cultivars from leaf photosynthetic biochemistry to crop canopy architecture. A particular focus in both areas 1 and 3, is adaptation to global atmospheric change, which utilizes the unique SoyFACE facility that my group initiated at Illinois. My group is conducting work with maize, soy, sorghum, sugarcane, cassava and the energy crop, Miscanthus.

Steve Moose
Associate Professor of Maize Functional Genomics/Genetics
The Moose laboratory is focused on defining the regulatory networks that control gene expression.  We use comparative and functional genomics approaches to discover genes whose expression changes during development or in response to environmental signals.  Genes with presumed regulatory functions are then tested for their phenotypic effects through genetic analysis of mutants, breeding populations, and transgenic plants.  Current projects in the lab focus on the regulation of leaf identity, seed composition, and response to nitrogen.

Rita Mumm
Associate Professor of Quantitative Genetics and Plant Breeding
My research program focuses in three main areas: 1) quantitative genetics (the inheritance and manipulation of traits controlled by many genes); 2) applications of information obtained at the DNA, RNA, and protein levels to the development of improved hybrids and varieties; and 3) deployment of traits created through genetic engineering, including efficient breeding strategies and stewardship of governmentally regulated materials. Much of this work has a strong computational component. The primary crop is maize, although applications developed in maize as a model crop are expanded to other plant species.

Nathan Schroeder
Assistant Professor of Nematology
Our lab studies the biology of plant-parasitic nematodes in order to develop novel control strategies. The most important pathogen of soybean is the soybean cyst nematode, Heterodera glycines. While resistant soybean varieties are available, the majority of these are derived from a single source and resistance-breaking populations are becoming more widespread. Corn is susceptible to over 60 species of plant-parasitic nematodes and yield losses of 20% have been ascribed to nematode damage in the Midwest. However, there are no commercial corn varieties resistant to plant-parasitic nematodes. We are interested in survival strategies of plant-parasitic nematodes and the molecular basis of how plant host signaling impacts survival adaptations.

Professor of Plant Molecular Biology,
Charles Adlai Ewing Chair in Soybean Molecular Genetics
Our laboratory investigates the expression, regulation, and transfer of plant genes, using the tools of molecular genetics and functional genomics.  Soybean genomic resources have expanded dramatically in recent years, culminating with the recent sequencing of its genome.  Using this information and the microarray resources developed in our laboratory, we dissect gene networks operating during soybean seed and seedling development in both normal and mutant lines.  We focus on seed traits (protein, oil, and flavonoids) that make soybean the second most valuable economic crop in the U.S.  We also seek to unravel how endogenous small RNAs (microRNAs and siRNAs) silence their target genes during soybean development, using ultra-high throughput sequencing of small RNA populations in various organ systems of the plant.

David R. Walker
Assistant Professor of Plant Genetics
USDA-ARS Research Geneticist
My research is focused on the identification and exploitation of soybean germplasm with resistance to soybean rust. The ultimate applied research goal is to develop high-yielding, rust-resistant breeding lines by transferring resistance genes from a variety of germplasm sources to the genetic backgrounds of high-yielding but susceptible soybean lines and cultivars. Complementary studies are being conducted to investigate the genetics of resistance to soybean rust, the genomic locations and contributions of genes associated with resistance, and methods that can be used to effectively and efficiently evaluate rust resistance in field, greenhouse and laboratory studies. Other areas of research include investigations of host plant-rust interactions, soybean tolerance to rust infections, and development of improved integrated management strategies that combine host resistance with chemical and cultural approaches to controlling soybean rust epidemics.

Assistant Professor
Research in my laboratory focuses on bacterial plant pathogens and the diseases they cause. Our long term goal is to understand how microbial pathogens cause disease in higher plants, how host plants respond to bacterial infection, and how bacterial pathogens respond under different environmental conditions or during interactions with host plants. Better understanding the genetics and molecular mechanisms of bacterial pathogenesis, and practical information on how bacterial pathogens interact with host plants and environmental conditions will lead to the development of improved disease management strategies and reduce the threat to sustainable agriculture and food supply. Both bacterial genetics and comparative and functional genomics approaches will be used in my research program.
