We are conducting various field and greenhouse experiments to document variability among these accessions in traits such as seed germinability, competitiveness, and photosynthetic rate, and hope to relate these data with the molecular data. Here at the University of Illinois, colleagues have recently built up the technology for gene expression profiling using soybean DNA-microarrays. I am initiating projects in my lab to take advantage of this tool and apply it towards weed science research. For example, gene expression profiling is a powerful new way to study the effects of herbicides in plants. This course, which I teach every fall semester, covers fundamentals of weed biology, ecology, and management.
Emphasis is placed on principles that are relevant to both crop and non-crop ecosystems.
