Identification of deoxynivalenol- and nivalenol-producing chemotypes of Gibberella zeae by using PCR.
Gibberella zeae, a major cause of cereal scab, may be divided into two chemotypes based on production of the trichothecenes deoxynivalenol (DON) and nivalenol (NIV). We cloned and sequenced the gene cluster for trichothecene biosynthesis from each chemotype. G. zeae H-11 is a DON producer isolated from corn, and G. zeae 88-1 is a NIV producer from barley. We sequenced a 23-kb gene cluster from ...
متن کاملDevelopment of a Generic PCR Detection of 3-Acetyldeoxy-nivalenol-, 15-Acetyldeoxynivalenol- and Nivalenol-Chemotypes of Fusarium graminearum Clade
Fusarium graminearum clade pathogens cause Fusarium head blight (FHB) or scab of wheat and other small cereal grains, producing different kinds of trichothecene mycotoxins that are detrimental to human and domestic animals. Type B trichothecene mycotoxins such as deoxynivalenol, 3-acetyldeoxynivalenol (3-AcDON), 15-acetyldeoxynivalenol (15-AcDON) and nivalenol (NIV) are the principal Fusarium m...
متن کاملTri13 and Tri7 determine deoxynivalenol- and nivalenol-producing chemotypes of Gibberella zeae.
Gibberella zeae, a major cause of cereal scab, can be divided into two chemotypes based on production of the 8-ketotrichothecenes deoxynivalenol (DON) and nivalenol (NIV). We cloned and sequenced a Tri13 homolog from each chemotype. The Tri13 from a NIV chemotype strain (88-1) is located in the trichothecene gene cluster and carries an open reading frame similar to that of Fusarium sporotrichio...
متن کاملInter-laboratory study of an LC-MS/MS method for simultaneous determination of deoxynivalenol and its acetylated derivatives, 3-acetyl-deoxynivalenol and 15-acetyl-deoxynivalenol in wheat.
To validate an LC-MS/MS method for simultaneous determination of deoxynivalenol (DON) and its acetylated derivatives, 3-acetyl-deoxynivalenol (3ADON) and 15-acetyl-deoxynivalenol (15ADON), in wheat using a multifunctional column, an inter-laboratory study was performed in 9 laboratories using one blank wheat sample, three spiked wheat samples (10, 50, 150 µg/kg) and one naturally contaminated w...
متن کاملIdentification of the classical enterotoxin genes of Staphylococcus aureus in various foods by multiplex PCR assay
Background: An annual update of information about the prevalence of Staphylococcus aureus and staphylococcal enterotoxins (SEs) genes is required in every geographic area. Aims: This study was conducted to investigate the prevalence of the bacterium and type of associated enterotoxin genes in different food samples, using multiplex polymerase ...
