Variability of aflatoxin and cyclopiazonic acid production by Aspergillus section flavi from different substrates in Argentina.
Aspergillus section flavi strains isolated from peanuts, wheat and soybean grown in Argentina were screened for aflatoxins (type B and G) and cyclopiazonic acid (CPA) production. Aspergillus flavus was the predominant species in all substrates, although there was almost the same proportion of A. flavus and Aspergillus parasiticus in peanuts. Aspergillus nomius was not found. Incidence of aflato...
متن کاملEvaluating Aflatoxin Gene Expression in Aspergillus Section Flavi.
The determination of aflatoxin production ability and differentiation of aflatoxigenic strains can be assessed by monitoring the expression of one or several key genes using reverse transcription polymerase chain reaction (RT-PCR). We herein describe the methods for RNA induction, extraction, and quality determination, and the RT-PCR conditions used to evaluate the ability of a given Aspergillu...
متن کاملStudies on Aspergillus Section Flavi from Peanut in Iran
During 2010 and 2011, Aspergillus species from section Flavi were isolated from rhizosphere in main peanut-growing region of Iran, Astaneh-e Ashrafiyeh, Guilan Province (northern Iran). The soil samples were taken from fruiting zone of peanuts in 3 districts and 10 locations, during the pod-filling period. The populations of Aspergillus section Flavi showed significant differences in cfu g-1 am...
متن کاملEvaluation of the aflatoxin biosynthetic genes for identification of the Aspergillus section Flavi.
Several fungi in the Aspergillus section Flavi have been widely used for fermentative food production, while some related species in the section are known to produce mycotoxin(s) that causes mycotic diseases. Common evolutionary markers, such as rRNA gene sequences and their internal transcribed spacers, cannot differentiate these non-aflatoxin-producing species from aflatoxin producers. Multil...
متن کاملA Survey on Contamination of Iranian Pistachio Cultivars to Aspergillus Section Flavi and Aflatoxin
Population density of Aspergillus section Flavi in pistachio kernels of Iranian cultivars was studied in main pistachio growing areas of Iran during 2015 to 2017. In order to investigate the rate of contamination of pistachio cultivars to Aspergillus section Flavi and aflatoxins, 13 pistachio cultivars, including Akbari, Kaleh-ghouchi, Ovhadi, Ahmad-aghaee, M...
