Host-microbe interactions.: A major focus of research in the Stacey lab is understanding the molecular basis of plant-microbe interactions. Two systems are being investigated. The first is the symbiosis between the bacterium Bradyrhizobium japonicum and its host plant, soybean. The result of this interaction is the establishment of a novel organ, nodule, on the root of the host. Inside this organ, B. japonicum fixes atmospheric nitrogen, which the plant can utilize. Our work on this symbiosis focuses both on the symbiont and the plant host. With regard to the bacterium, we are utilizing functional genomic tools to understand the contribution of the symbiont to the symbiosis. We are utilizing similar approaches to understand the contribution of the plant host to the symbiosis. A key molecule essential for the establishment of the symbiosis is a lipo-chitin signal molecule. An investigation of the role of this molecule in the legume symbiosis has led us to a more general interest in the role of chitin recognition in plants. Thus, the second system under investigation is fungal-plant interactions and the role of chitin, found in fungal cell walls, as an elicitor of plant defense reactions. We recently isolated the putative plant receptor for chitin and are exploring the role of this receptor and downstream signaling processes in the plant defense to fungal pathogens
Soybean genomics and biotechnology. As part of the growing family of researchers at MU who are interested in soybean biology, our laboratory is contributing to the development of soybean genomic research. The goal of this research is to identify genes and traits, which can benefit soybean agriculture. For example, at MU, we are developing, in collaboration with other laboratories, first rate facilities for high-throughput molecular breeding of soybean and transformation capabilities for creating transgenic soybean with improve agronomic and/or nutritional traits. In addition, we are developing a transposon-tagged library of soybean mutants that can be used to explore soybean gene function. These resources will become very valuable with the expected release of the complete soybean genome sequence in 2008.
