The presence, but not expression, of homologs of three structural genes and a regulatory
gene necessary for aflatoxin biosynthesis in Aspergillus parasiticus and A. flavus was shown …

Some strains of Aspergillus oryzae were shown to have homologs of aflR, a regulatory gene
for aflatoxin synthesis in Aspergillus parasiticus. Transcription of an aflR homolog was …

RNAs from three Aspergillusparasiticus and three Aspergillus sojae isolates were probed
with seven genes involved in aflatoxin biosynthesis. Previously published work and …

We studied the role of the regulatory gene aflR and its product, AflR, in the biosynthesis of
aflatoxin in Aspergillus. Western blot and enzyme-linked immunosorbent assay analyses …

To help assess the potential for aflatoxin production by Aspergillus oryzae, the structure of
an aflatoxin biosynthesis gene homolog cluster in A. oryzae RIB 40 was analyzed. Although …

The Aspergillus parasiticus aflR gene, a gene that may be involved in the regulation of
aflatoxin biosynthesis, encodes a putative zinc finger DNA-binding protein. PCR and …

The genes required for the synthesis of aflatoxin (AF) in Aspergillus flavus and Aspergillus
parasiticus have been shown to be clustered on a chromosome in these fungi. Transcription …

An unusual mutation at the afl-1 locus, affecting aflatoxin biosynthesis in Aspergillus flavus
649, was investigated. The inability of strain 649 to produce aflatoxin was found to be the …

An Aspergillus parasiticus gene, designated apa-2, was identified as a regulatory gene
associated with aflatoxin biosynthesis. The apa-2 gene was cloned on the basis of …

To investigate the structure of the aflatoxin gene cluster in Aspergillus oryzae, 39 strains
belonging to this species were examined for the existence of pksA, fas-1A, aflR and vbs, and …
