Cloning of a gene associated with aflatoxin B1 biosynthesis in Aspergillus parasiticus.

Current genetics - 1 Mar 1992

Chang P K, Skory C D, Linz J E

Abstract excerpt

A cosmid library was constructed by inserting genomic DNA isolated from a wild-type aflatoxin-producing strain of Aspergillus parasiticus (SU-1) into a cosmid vector containing an homologous nitrate reductase (niaD) gene as a selectable marker. One cosmid was isolated which complemented an aflatoxin-deficient, nitrate-nonutilizing mutant strain, A. parasiticus B62 (nor-1, niaD), to aflatoxin production. Deletion...
