Fusarium species from Nepalese rice and production of mycotoxins and gibberellic acid by selected species
Article Abstract:
Traditional Nepalese practices for drying and storing grain may prevent contamination of the grain with Fusarium mycotoxins. Researchers found many different species of Fusarium on rice seeds collected from Nepalese farms, but no detectable mycotoxins on mature rice.

Heritability of fumonisin B1 production in Gibberella fujikuroi mating population A
Article Abstract:
Six mating populations of Gibberalla fujikuroi (anamorphs, Fusarium section Liseola), designated A to F, are recognized. Most stains of the A population can produce fumonisins at high levels when grown on corn kernels. An investigation was conducted to determine the heritability of fumonisin production. Random ascospore and tetrad analyses showed that fumonisin production is inherited as a single gene or group of closely-linked genes. This characteristic was not linked to mating type and spore-killer traits. These results suggest that mating population A may be used for the further study of the genetics of fumonisin production.

Incidence of Fusarium spp. and levels of fumonisin B1 in maize in western Kenya
Article Abstract:
The prevalence of Fusarium species and levels of fumonisin B1 in corn from western Kenya has been determined. The Fusarium species produce fumonisins which are mycotoxins that can cause equine leucoencephalomalacia, porcine pulmonary edema and liver cancer in laboratory rats. Fusarium infection was assessed in 153 corn samples by culturing kernels on a selective medium. Results reveal the presence of F. subglutinans, graminearum, oxysporum, solani but the moniliforme species was the most frequently encountered in the corn samples. Negligible amounts of fumonisin B1 was found in most of the samples based on high-performance liquid chromatography data.
