abstract：:The nor-1 gene in the filamentous fungus Aspergillus parasiticus encodes a ketoreductase involved in aflatoxin biosynthesis. To study environmental influences on nor-1 expression, we generated plasmid pAPGUSNNB containing a nor-1 promoter-beta-glucuronidase (GUS) (encoded by uidA) reporter fusion with niaD (encodes ni...
