Technical Abstract: Corn is contaminated every year with aflatoxin in one or more regions of southern states of Georgia, Lousiana, Texas, North Carolina and Mississippi. In 1998, about 50% of the corn produced at Mississippi State was found to be contaminated with aflatoxin above legal limits. Aflatoxins are potential carcinogens produced by Aspergillus fungi which easily invade corn plants through physical damages done by the insects like Fall Army Worm (FAW) and Southwestern corn borer. Hence production of corn genotypes which are resistant both to fungal and insect infection should be adopted. We are working with resistant genotypes of maize and trying to find genes common to both fungal and insect resistance. In this move, we are performing a genomic profile to identify candidate genes involved in maize defense response during insect and as well as in fungal infections through high-throughput micro array analysis. SNPs will then be identified to generate molecular markers to assist pilot breeding program which will eventually benefit both corn breeders and corn producers.
