Abstract

ABSTRACTFusarium graminearum is among the main causal agents of Fusarium head blight (FHB), or scab, of wheat and other cereals, caused by a complex of Fusarium species, worldwide. Besides causing economic losses in terms of crop yield and quality, F. graminearum poses a severe threat to animal and human health. Here, we present the first draft whole-genome sequence of the mycotoxigenic Fusarium graminearum strain ITEM 124, also providing useful information for comparative genomics studies.

Highlights

Fusarium graminearum is among the main causal agents of Fusarium head blight (FHB), or scab, of wheat and other cereals, caused by a complex of Fusarium species, worldwide
F. graminearum ITEM 124 is able to produce deoxynivalenol (DON), the best-known mycotoxin belonging to trichothecenes [3]
A competition test on rice kernels inoculated with F. graminearum ITEM 124 and the beneficial fungus Trichoderma gamsii T6085 highlighted a reduction of the amount of DON to almost 92% as a direct consequence of a decreased biomass of the pathogen

Summary

Introduction

Fusarium graminearum is among the main causal agents of Fusarium head blight (FHB), or scab, of wheat and other cereals, caused by a complex of Fusarium species, worldwide. F. graminearum ITEM 124 (http://server.ispa.cnr.it/ITEM/Collection/), known as ATCC 56091, was isolated in 1976 from rice harvested in Vercelli, Piemonte, Italy. F. graminearum ITEM 124 is able to produce deoxynivalenol (DON), the best-known mycotoxin belonging to trichothecenes [3]. This class of mycotoxins acts as an inhibitor of cell protein synthesis [4].
