Homologs of Aflatoxin Biosynthesis Genes and Sequence of aflR in Aspergillus oryzae andAspergillus sojae

ABSTRACT

The presence, but not expression, of homologs of three structural genes and a regulatory gene necessary for aflatoxin biosynthesis inAspergillus parasiticus and A. flavus was shown for A. oryzae and A. sojae. Homologs of the regulatory gene aflR were cloned and sequenced fromA. oryzae and A. sojae.
