Trichothecene and beauvericin mycotoxin production and genetic variability in Fusarium poae isolated from wheat kernels from northern Italy.
Abstract
The importance and widespread incidence of Fusarium poae as a natural contaminant of wheat in differentclimatic areas warrants investigation into the genetic diversity and toxin profile of a northern Italy population.Eighty-one strains of F. poae isolated from durum wheat kernels, identified by species-specific polymerase chainreaction and translation elongation factor-1 gene sequence analysis, were genetically characterized by theamplified fragment length polymorphism (AFLP) technique and analysed by high-pressure liquid chromatographyfor their ability to produce the beauvericin (BEA) and trichothecene mycotoxins. A high level of variabilitywas observed by using AFLP analyses, with the lowest level of genetic similarity among the strains beingapproximately 61%. Most of the strains, 95%, produced BEA at52655 mg g1; 88% produced the trichothecenenivalenol at5865 mgg1 and 76% produced the trichothecene fusarenon-X at5167 mg g1. These data show thatF. poae can produce high amounts of BEA together with trichothecenes, and can represent a high potentialmycotoxin risk in Italy for wheat colonized by this species.
