Summary of video content Prof. Lee A. Hadwiger of Washington State University's dept. of Plant Pathology describes how pea plants resists a bean diseases. Hadwiger and his colleagues have researched plant diseases for many years and now understand better how defense genes are activated. Hadwiger summarizes his researach to date and illustrates how modern technologies, such as chromatin immunoprecipitation, can be utilized in identifying nuclear proteins involved in gene activation. Additional Information A more scientific description of this topic with the proper citations is available in the following review paper: Hadwiger LA. 2008. Pea-Fusarium solani interactions contributions of a system toward understanding disease resistance. Phytopathology 98:372-379.
