Fusarium graminearum and Fusarium sporotrichioides produce the trichothecene mycotoxins 15-acetyldeoxynivalenol and T-2 toxin, respectively. In both species, disruption of the P450 monooxygenase-encoding gene, Tri4, blocks production of the mycotoxins and leads to the accumulation of the trichothecene precursor trichodiene. To further characterize its function, the F. graminearum Tri4 (FgTri4) ...

Two vomitoxin-producing isolates of Fusarium spp. were grown on cracked corn for 1 to 8 weeks at 15, 20, 25, 28, and 32 degrees C. Maximum production of vomitoxin by Fusarium graminearum Schw. NRRL 5883 occurred at 30 degrees C and 40 days, and that by Fusarium roseum Schw. NRRL 6101 occurred at 26 degrees C and 41 days. These optimum production points were determined from response surface cont...

Identification of Fusarium species by traditional methods requires specific skill and experience and there is an increased interest for new molecular methods for identification and quantification of Fusarium from food and feed samples. Real-time PCR with probe technology (Taqman) can be used for the identification and quantification of several species of Fusarium from cereal grain samples. Ther...

Fusarium head blight (FHB) is one of the most economically important and destructive fungal diseases of wheat (Triticum aestivum L.). Golestan province, one of the most important zones of wheat cultivation in Iran, is also known for its high rate of digestive tract cancer, which has been attributed to many biotic factors such as fungal toxins. In order to investigate the distribution of toxicog...

Plant lipid transfer proteins (LTPs) are members of the pathogenesis-related proteins (PR-14) and some of them exhibit activity against phytopathogenic fungi. To investigate whether rice LTP2 plays a role in antifungal activity, the coding region of an Iranian rice Ltp2 gene was cloned into expression vector pET24-d(+) and then expressed in Escherichia coli Rosetta strain (DE3). The potential a...

Tomato (Solanum lycopersicum L.) is of great socio-economic importance. Unfortunately, its production limited in Togo by fungal diseases and bacterial wilt caused Ralstonia solanacearum (Rs). The objectives the study are to establish status major tomato control approaches used producers. methodology led a field survey allowing evaluation incidence identification their endogenous methods. In lab...

Many fungi-infecting viruses, which are termed mycoviruses, have been identified, and most do not cause any visible symptoms. Some mycoviruses, however, can attenuate the virulence of the infected fungi, a phenomenon referred to as hypovirulence. To study fungus responses to virus infection, we established a model system composed of Fusarium graminearum and four mycoviruses including FgV1 (Fusa...

Biological control consists of using one organism to attack another that may cause economic damage to crops. Integrated Pest Management (IPM) is a very common strategy. The white mold produced by Sclerotinia sclerotiorum (Lib.) causes considerable damage to bean crops. This fungus is a soil inhabitant, the symptoms of which are characterized by water-soaked lesions covered by a white cottony fu...

Fusarium graminearum is one of the most important fungal pathogens of wheat, barley, and maize worldwide. This announcement reports the genome sequence of a highly virulent Australian isolate of this species to supplement the existing genome of the North American F. graminearum isolate Ph1.
