Soybean Pod Blight and Root Rot Caused by Lineages of the Fusarium graminearum and the Production of Mycotoxins
Queima da vagem e podridão de raízes da soja causadas por linhagens de Fusarium graminearum e produção de micotoxinas Amostras de sementes de soja (Glycine max) produzidas no Sul do Brasil estavam infetadas com Fusarium graminearum. Para determinar se membros desse complexo de espécies eram patogênicos à soja, seis isolados do fungo, originados de sementes soja, foram adicionados ao solo numa d...
متن کاملTrichothecene mycotoxins from Fusarium culmorum cultures.
Chemical analysis of the culture filtrates of Fusarium culmorum CMI 14764 has demonstrated the presence of seven trichothecene mycotoxins. Major metabolites are 3-acetyldeoxynivalenol and 7 alpha, 8 alpha-dihydroxycalonectrin, with 3,15-diacetyldeoxynivalenol, deoxynivalenol, calonectrin, isotrichodermin and 12,13-epoxytrichothec-9-ene (EPT) as minor products. The occurrence of the rarely encou...
متن کاملNatural Contamination with Mycotoxins Produced by Fusarium graminearum and Fusarium poae in Malting Barley in Argentina
Two of the most common species of toxin-producing Fusarium contaminating small cereal grains are Fusarium graminearum and F. poae; with both elaborating diverse toxins, especially deoxynivalenol (DON) and nivalenol (NIV), respectively. The objective of our work during the 2012-2014 growing seasons was to screen crops for the most commonly isolated Fusarium species and to quantify DON and NIV to...
متن کاملFusarium graminearum Tri12p influences virulence to wheat and trichothecene accumulation.
The gene Tri12 encodes a predicted major facilitator superfamily protein suggested to play a role in export of trichothecene mycotoxins produced by Fusarium spp. It is unclear, however, how the Tri12 protein (Tri12p) may influence trichothecene sensitivity and virulence of the wheat pathogen Fusarium graminearum. In this study, we establish a role for Tri12 in toxin accumulation and sensitivity...
متن کاملBiosynthesis of trichothecene mycotoxins in Fusarium culmorum cultures.
A high yielding production of the trichothecene mycotoxin 3-acetyldeoxynivalenol (3-AcDON) in cultures of Fusarium culmorum is described. By supplying [14C]acetate, 14C-labelled 3-AcDON suitable for further metabolic studies has been obtained. The pattern of labelling has been ascertained by using 13C-labelled acetate precursors, and is in line with established biosynthetic data. A second trich...
