Identification, Characterization, And Genetic Comparison Of Fusarium Species Isolated From Switchgrass (Panicum Virgatum L.), Tamara Annette Collins

Masters Theses

Fusarium spp. are ubiquitous, soilborne and seedborne pathogens that affect over 100 economically important plant hosts annually, resulting in billions of dollars in economic losses. They cause a variety of plant disease symptoms including, crown, root, and stem rots, wilts, and foliar necrosis. Furthermore, they produce harmful mycotoxins that are detrimental to the health of animals and humans. Members of this genus have been isolated from diseased tissues of switchgrass. The objective is to correctly identify and classify Fusarium isolates to species using both classic phenotypic characterization and current genetic technologies of DNA extraction and polymerase chain reaction and create …
