Aspergillus flavus, like approximately one–third of ascomycete fungi, is thought to be
cosmopolitan and clonal because it has uniform asexual morphology. A. flavus produces …

Aspergillus flavus and A. parasiticus are closely related species belonging to the Aspergillus
section Flavi. Both species can produce aflatoxins, but not all isolates of either species do …

Aflatoxins produced by Aspergillus flavus are potent carcinogens that contaminate
agricultural crops. Recent efforts to reduce aflatoxin concentrations in crops have focused on …

A new aflatoxigenic species of Aspergillus, A. bombycis, was discovered during isolation of
fungi from insect frass collected in silkworm rearing houses in Japan. The new species …

Aspergillus flavus is the major producer of carcinogenic aflatoxins (AFs) in crops worldwide.
Natural populations of A. flavus show tremendous variation in AF production, some of which …

Aflatoxin contamination of foods and feeds is a world-wide agricultural problem. Aflatoxin
production requires expression of the biosynthetic pathway regulatory gene, aflR, which …

The aflatoxin-producing fungi Aspergillus flavus and A. parasiticus show many phenotypic
similarities with the nonaflatoxigenic species A. oryzae and A. sojae which are widely used …

Aspergillus flavus is a common filamentous fungus that produces aflatoxins and presents a
major threat to agriculture and human health. Previous phylogenetic studies of A. flavus …

The fungal phylum Ascomycota comprises a large proportion of species with no known
sexual stage, despite high genetic variability in field populations. One such asexual species …

Relationships among 47 fungal isolates belonging to Aspergillus flavus sect. flavi were
inferred from restriction site variability in a portion of the Taka-amylase A gene. Portions (1 …
