Diversity of aflatoxinproducing fungi and their impact on food safety in subSaharan Africa por Probst, C., Bandyopadhyay, Ranajit, Cotty, P.J.

“…Phylogenetic analyses of partial sequencesof the nitrate reductase gene (niaD, 1.3 kb) and the aflatoxin pathway transcription factor gene (aflR, 1.7 kb)were used to verify isolate assignments into species and lineages. Phylogenetics resolved S strain isolates producingonly B aflatoxins into two lineages fully supported by sizes of deletions in the gene region spanning the aflatoxinbiosynthesis genes cypA (aflU) and norB (aflF). …”

Combining ability of diverse maize inbred lines under Striga infestation in Nigeria and Benin por Yallou, C., Menkir, A., Adetimirin, Victor O., Kling, J.

“…The ten lines were crossed in a diallel fashion and the resulting 45 single-cross hybrids were evaluated under artificial striga infestation at two locations each in Nigeria and Republic of Benin for two years. The results showed that general combining ability (GCA) mean squares were much larger than those for specific combining ability (SCN for grain yield under Striga infestation, Striga damage symptom score, and numbers of emerged Striga plants, indicating that for these traits, additive genetic effects were more important than non-additive effects. …”
