Identification of Novel Sources of Resistance to Ear Rot and Aflatoxin Accumulation in Corn

Institutions
Southern Illinois University
Start date

End date
2010
Objective

To identify and characterize novel endogenous sources of resistance to ear rot and aflatoxin accumulation in corn.

More information
APPROACH: The focus of this research will be on a subset of the proteins that have been identified in proteomic screening conducted at the USDA/ARS/SRRC lab, as putatively involved in aflatoxin accumulation and/or ear rot resistance. Identified proteins will be further characterized and the corresponding genes will be isolated and cloned. Proteins will be expressed in a suitable in vitro system and their possible physiological functions will be investigated. Knowledge of A. flavus functional genomics techniques will be used to identify/test proteins for target-specific interruption of aflatoxin biosynthesis. The information obtained through the above studies will be used to explore the potential of the identified genes to serve as markers in marker-assisted breeding programs.
