Objective
The overall goal of this research is to understand how selected ecological groups of symptomless fungal endophytes from maize interact with kernel rotting pathogens and apply this knowledge to reduce disease severity and mycotoxin contamination of the grain. The results obtained through these objectives should produce novel strategies for preventing pathogen related losses in corn productivity and grain quality in a changing global environment. Specific objectives are: Objective 1: Examine the biocontrol potential of Acremonium zeae in providing an effective defense against mycotoxin producing kernel rotting fungi. Objective 2: Discover and characterize metabolites produced by fungal endophytes and pathogens of cereals that support symptomless infection and survival. Objective 3: Characterize fungal endophyte diversity in maize and develop phylogenetic systems to predict the role of novel endophytes in host-pathogen interactions. Objective 4: Determine the production and bioactivity of chitinase modifying proteins (cmp) among common fungal endophytes and pathogens of maize and examine their role in seed pathology.
