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 کاملContamination of Stored Pistachios to Aspergillus Section Flavi and Aflatoxins
Background: Contamination of stored pistachio nuts to Aspergillus section Flavi and aflatoxins (AFs) as well as effective parameters on fungal growth and AF production during storage was assayed. Methods: Twenty one pistachio nut samples were taken from some warehouse of Damghan county. Different parameters of storage, including temperature, relative humidity, and pest infestation were recorded...
متن کاملAspergillus parasiticus communities associated with sugarcane in the Rio Grande Valley of Texas: implications of global transport and host association within Aspergillus section Flavi.
In the Rio Grande Valley of Texas (RGV), values of maize and cottonseed crops are significantly reduced by aflatoxin contamination. Aflatoxin contamination of susceptible crops is the product of communities of aflatoxin producers and the average aflatoxin-producing potentials of these communities influence aflatoxin contamination risk. Cropping pattern influences community composition and, ther...
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 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...
