Influences of climate on aflatoxin producing fungi and aflatoxin contamination.
Aflatoxins are potent mycotoxins that cause developmental and immune system suppression, cancer, and death. As a result of regulations intended to reduce human exposure, crop contamination with aflatoxins causes significant economic loss for producers, marketers, and processors of diverse susceptible crops. Aflatoxin contamination occurs when specific fungi in the genus Aspergillus infect crops...
متن کاملDelivery systems for biological control agents to manage aflatoxin contamination of pre-harvest maize.
While soil application of a competitive non-toxigenic Aspergillus flavus strains is successful in reducing aflatoxin contamination in certain crops, direct application to aerial reproductive structures could be more effective for maize. A sprayable, clay-based water-dispersible granule formulation was developed to deliver non-toxigenic A. flavus strain K49 directly to maize ears. The efficacy o...
متن کاملDrought, pod yield, pre-harvest Aspergillus infection and aflatoxin contamination on peanut in Niger
Soil moisture and soil temperature affect pre-harvest infection with Aspergillus flavus and production of aflatoxin. The objectives of our field research in Niger, West Africa, were to: (i) examine the effects of sowing date and irrigation treatments on pod yield, infection with A. flavus and aflatoxin concentration; and (ii) to quantify relations between infection, aflatoxin concentration and ...
متن کاملIdentification of Maize Kernel Endosperm Proteins Associated with Resistance to Aflatoxin Contamination by Aspergillus flavus.
ABSTRACT Aflatoxins are carcinogens produced mainly by Aspergillus flavus during infection of susceptible crops such as maize (Zea mays). Previously, embryo proteins from maize genotypes resistant or susceptible to A. flavus infection were compared using proteomics, and resistance-associated proteins were identified. Here, we report the comparison of maize endosperm proteins from five resistant...
متن کاملstudy of aflatoxin-producing fungi contamination of raisins varieties produced in khorasane razavi province
the aim of this study was to investigate the mold contamination of main raisins varieties produced in khorasan razavi province with aflatoxin-producing fungi and determine amount of aflatoxins. for this purpose 50 samples were collected from different markets in kashmar, khalil abad, bardaskan, mashhad and quchan (10 samples from each city). the result showed that from 50 raisin samples, 44 sam...
