ENVIRONMENTAL FACTORS INVOLVED IN PREHARVEST ASPERGILLUS FLAVUS INFECTION OF COTTONSEED

AFLATOXIN FORlYIATION IN PREHARVEST IVIAIZE EARS COINOCULATED WITH ASPERGILLUS FLAVUS AND ASPERGILLUS NIGER

Aspergillus jlavus and Aspergillus niger commonly co-occur in preharvest maize and one report suggests that this association promotes a greater incidence of aflatoxin. Other studies have shown that Aspergillus niger can prevent, or substantially reduce, aflatoxin formation by Aspergillus jlavus in autoclaved maize kernels, and this led us to examine the effect of A. niger on aflatoxin formation...

Aspergillus flavus infection and aflatoxin production in fig fruits.

Immature fig fruits did not support colonization and aflatoxin production by Aspergillus flavus Lk. but became susceptible when ripe. While sun-drying on the tree, fruits were particularly vulnerable to fungal infection and colonization. Aflatoxin accumulation equaled levels frequently reported for such seeds as peanuts and cereal grains.

Gene deletion patterns in non-aflatoxigenic isolates of Aspergillus flavus

Fifteen non-aflatoxigenic strains of Aspergillus flavus, represent a wide range of geographic regions of Iran (six provinces include Fars, Ardebil, Guilan, Golestan, Kerman and Semnan) and vegetative compatibility groups (VCGs), were collected from corn (Zea mays L.), peanut (Arachis hypogaea L.) and pistachio (Pistachia vera L.) soils and kernels, were screened for the presence of aflatoxin bi...

Environmental influences on maize-Aspergillus flavus interactions and aflatoxin production

Since the early 1960s, the fungal pathogen Aspergillus flavus (Link ex Fr.) has been the focus of intensive research due to the production of carcinogenic and highly toxic secondary metabolites collectively known as aflatoxins following pre-harvest colonization of crops. Given this recurrent problem and the occurrence of a severe aflatoxin outbreak in maize (Zea mays L.), particularly in the So...
