Sommario/riassunto

The fungus Fusarium is a major plant pathogen that causes disease in nearly every agriculturally important plant. In addition, some strains produce mycotoxins that can cause serious illness in humans and livestock. The enormous economic importance of, and health hazards posed by, Fusarium have fuelled research by scientists worldwide into its biochemistry, genetics, genomics, proteomics, and metabolomics. The primary aim of this research is the identification of strategies to reduce crop diseases and the risks posed to human and animal health. The wealth of information derived from this resear
