Abstract

Abstract: F. graminearum is an agent that causes Fusarium head blight (FHB), which greatly reduces wheat production. FHB has a direct influence on human and on animal health because of the mycotoxin production in the wheat grain. Study of Fusarium spp . and its association with the host is facilitated by the availability of F. graminearum's functional genomic sequence and proteomic resources. These are increasingly used to investigate the biochemical composition of fungi and their biological interactions. Differentially activated defense responses such as transcriptomic, proteomic and metabolomics are studied to identify the resistance mechanisms against the initial Fusarium infection and infection of host tissues. FHB resistance associated with secondary cell wall thickening is a result of phenolic glucoside, hydroxycinnamic acid and flavonoid accumulation. The results in this paper increase our understanding of the molecular association between F. graminearum and its host. Knowledge of the host, pathogens and their interactions will be efficient tools for planning new and useful approaches to control FHB disease. Highlights: F. graminearum is an agent that causes Fusarium head blight, which greatly reduces wheat production. Source of resistant cultivars, from an economical point of view, is the most effective control method for plant diseases. The metabolome comprises of the full set of small molecules produced by an organism. Plant cells contain cell walls as a mechanical protection to diseases.
