Aflatoxin contamination (AC) in maize, caused by the fungal pathogen Aspergillus flavus(Link), starts at pre-harvest stage. Hence, interventions that reduce entry and development of A. flavus in the field are required. Trials were carried out at Seatondale and Igeri, to evaluate the effects of ni...

Maize, a staple food in many African countries including Kenya, is often contaminated by toxic and carcinogenic fungal secondary metabolites such as aflatoxins and fumonisins. This study evaluated the potential use of a low-cost, multi-spectral sorter in identification and removal of aflatoxin- a...

Cassava is an important root crop to resource-poor farmers in marginal areas, where its production faces drought stress constraints. Given the difficulties associated with cassava breeding, a molecular understanding of drought tolerance in cassava will help in the identification of markers for us...

Background: Argonaute (AGO) proteins bind to small-interfering (si)RNAs and micro (mi)RNAs to target RNA silencing against viruses, transgenes and in regulation of mRNAs. Plants encode multiple AGO proteins but, in Arabidopsis, only AGO1 is known to have an antiviral role. Methodology/Principal F...

This article sets the background for an exciting new linkage between Australian and Africa-based scientists who will use NIR to enhance the safety and value of traditional African crops. It has long been advocated that NIR spectroscopy should be deployed in this fashion because of its inherent ad...

Sorghum was the first indigenous African crop to have a completed genome sequence. This provides an invaluable tool for understanding sorghum traits genetically and identifying useful molecular markers. The challenge is to extract relevant information to improve the diverse complex traits of sorg...

A total of 202 poultry feed and its raw ingredients collected from different agroecological zones of Cameroon were examined for total mycoflora and the ability of A. flavus isolates to produces aflatoxin B1. Dilution plating was used for fungal isolation. The mean fungal contamination levels were...

Food security considerations have shifted in recent years, with the recognition that available food should also be nutritious and safe. There is a growing evidence base for contamination of maize and other crops by fungal toxins in the tropics and sub-tropics. As an initial snapshot of contaminat...
