Interpretive Summary:

Technical Abstract: The production of quality peanuts is the number one goal of the U.S. peanut industry since the majority of peanuts produced in the U.S. are for human consumption. The most serious challenge to quality peanuts is preharvest contamination with aflatoxin, a potent cancer-producing toxin produced by the fungus Aspergillus flavus. Aflatoxin contamination occurs when peanuts growing in the field are exposed to severe drought during the latter part of the growing season. The development of peanut lines with resistance to drought stress would represent a major advance for the peanut industry. Our research goal is to identify factors associated with resistance to aflatoxin, drought stress or insects and to develop markers to assist in the transfer of the resistance to commercial peanut lines. We have identified a novel gene that may well be associated with drought tolerance in peanut. It is the first such gene identified in peanut and has characteristics similar to those identified in other crops for drought resistance. Additional study is needed, however, to characterize the gene and to develop markers for this gene.
