Studies 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 کاملVariability 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 کاملDistribution of Aspergillus section Flavi in soils of maize fields in three agroecological zones of Nigeria
Fungal communities in soils of Nigerian maize fields were examined to determine distributions of aflatoxin-producing fungi and to identify endemic atoxigenic strains of potential value as biological control agents for limiting aflatoxin contamination in West African crops. Over 1000 isolates belonging to Aspergillus section Flavi were collected from soil of 55 Nigerian maize fields located in t...
متن کاملAspergillus section Flavi community structure in Zambia influences aflatoxin contamination of maize and groundnut
Aflatoxins are cancer-causing, immuno-suppressive mycotoxins that frequently contaminate important staples in Zambia including maize and groundnut. Several species within Aspergillus section Flavi have been implicated as causal agents of aflatoxin contamination in Africa. However, Aspergillus populations associated with aflatoxin contamination in Zambia have not been adequately detailed. Most o...
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...
