Expression of aflR, veA and laeA as regulators of aflatoxins and cyclopiazonic acid biosynthesis pathway in Aspergillus flavus
In this study, the production of aflatoxin B1 (AFB1) and cyclopiazonic acid (CPA) was investigated in toxigenic and non-toxigenic Aspergillus flavus with respect to expression of aflR, veA and laeA genes that are involved to toxins production. A. flavus strains were cultured in YES broth at 28 °C for 4 days and the presence of (AFB1) and (CPA) was confirmed and measured by TLC and HPLC. The exp...
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 کاملOil and Fatty Acid Composition of Peanut Cultivars Grown in Pakistan
Quality and flavor of edible peanuts and its products are affected by fatty acid composition of oil. The information related to chemical composition of Peanut grown in the country are scarce, therefore, the present investigation was designed to determine the oil and fatty acid composition of some commonly grown peanut cultivars in Pakistan. Seven Peanut cultivars were grown during 2008 in rando...
متن کاملDetection of Aflatoxins in Peanut Oils Marketed in Peshawar, Pakistan Using Thin Layer Chromatography
Background: Aflatoxins (AFs) are natural toxins produced by fungus belonging to genus Aspergillus. These toxins are the secondary metabolites, which may cause teratogenic, mutagenic, and carcinogenic effects due to contamination of food. Peanut is an economically important crop, grown in many parts of the world. The main aim of this survey was to detect AFs in peanut oils marketed in Peshawar, ...
متن کاملRNAi-mediated Control of Aflatoxins in Peanut: Method to Analyze Mycotoxin Production and Transgene Expression in the Peanut/Aspergillus Pathosystem
The Food and Agriculture Organization of the United Nations estimates that 25% of the food crops in the world are contaminated with aflatoxins. That represents 100 million tons of food being destroyed or diverted to non-human consumption each year. Aflatoxins are powerful carcinogens normally accumulated by the fungi Aspergillus flavus and A. parasiticus in cereals, nuts, root crops and other a...
