Technical Abstract: The ability to induce microbial resistance in plants is of agricultural and economic significance. Resistance in some plants is correlated to the production of low molecular weight phenolic compounds collectively known as phytoalexins. Phytoalexins are thought to act by interfering with plasma membrane function. In the case of soybean (Glycine max), the phytoalexin of our interest has been previously identified as glyceollin. The production of glyceollin and its isomers may confer resistance to many microbial infections, potentially including the fungal pathogen Phakopsora pachyrhizi Sydow, which causes soybean rust. It is hypothesized that plants may be screened for disease resistance by identifying the production of specific phytoalexins such as glyceollin. Methods of identification and quantitation may include HPLC, UV-Vis spectroscopy, and GC-MS. These techniques may allow for the further identification of resistance traits in soybean and other plants.
