The purpose of this study is to microscopically monitor fungal invasion and its spread using fluorescent tags.To accomplish, the strains Colletotrichum graminicola, Collectrotrichum sublineola, and Cochliobolus heterostrophus will be genetically transformed with Green and Yellow Fluorescent Protein (GYP and YFP). These fluorescing strains will be selected for pathogenicity testing on host plants. Overall, developing fluorescent tagged fungi will aid in the research focused on understanding interactions of maize and sorghum plants with these strains.
