Species diversity and geographical distribution of Fusarium species on winter wheat in two regions in Sweden

TL;DRAbstract

Various Fusarium species causes some of the most common cereal diseases worldwide. Besides the yield losses that can be a result of these diseases, strains from several Fusarium species can produce mycotoxins, some very toxic. The aim of this study was to investigate which Fusarium species and how many that occurred in winter wheat grains from Malardalen and Kalmar lan, if there was any difference in the distribution of Fusarium fungi between the regions and the potential within species to produce mycotoxins belonging to the group trichothecenes. Winter wheat grains collected in 2009 from ten fields (unsprayed plots) in the two regions were analysed for Fusarium species. PCR was used to amplify the TEF region where after the samples were sequenced. The samples identified as Fusarium species were screened for the presence of the Tri5 gene necessary for trichothecene production. The results were compared with previously collected data on Fusarium spp. detected in the same ten fields
