Interpretive Summary:

Technical Abstract: Aflatoxin contamination is a serious health risk because of its toxic and carcinogenic properties, and because of its contamination in food and feed on human health and livestock. Host plant resistance to aflatoxin contamination is a complex trait, and dissecting this trait is an equally complex task. Globally the competitiveness of peanuts has been threatened by losses in productivity and food safety. The U.S. Peanut Genome Initiative (PGI) was launched in 2004, and expanded to global in 2006 to address these issues. Ultimately, the peanut genome sequencing project was launched in 2012 by Peanut Genome Consortium, a committed step by the world-wide peanut research community to meet the needs and the challenges. In this endeavor, a primary research objective is to develop genetic tools and genomic resources and molecular markers, along with germplasms with improved resistance to biotic and abiotic stresses. The outcome of these efforts will provide tools and resistant germplasms to breeders and enable more precise and effective solution to the problem. To accomplish the objective, two strategies are advanced: the first strategy uses genetic techniques to identify disease resistance germplasm and study the resistance traits for association with markers/genes. The marker(s) and genes associated with the traits will be used in germplasm evaluation and marker-assisted breeding. The second strategy will be to use the genomic resources available in peanut to study the genes responding to drought stress and disease resistance to identify genes/markers associated with the traits, which will be used as “candidate” genes for association studies for resistance to Aspergillus flavus and PAC. Further potential prevention technology and strategies could be employed to guide future research, such as “next-generation” genetics and genotype by re-sequencing for GWAS (genome wide association studies).
