Abstract excerpt
Aflatoxigenic Aspergillus flavus isolates always show, by using a multiplex PCR-system, four DNA fragments specific for aflR, nor-1, ver-1, and omt-A genes. Non-aflatoxigenic A. flavus strains give variable DNA banding pattern lacking one, two, three or four of these genes. Recently, it has been found and reported that some aflatoxin non-producing A. flavus strains show a complete set of genes. Because less is...
