Soybean is one of the most economically importantcrops in Argentina and Brazil. However, there is limited informationon the biodiversity of the FGSC from soybean ascompared to other crops of large-scale growing such as wheatand maize. A phylogenetic recognition of the Fusariumgraminearum species complex (FGSC) isolated from soybeanin Argentina and Brazil was performed in order to identifyspecies responsible for trichothecene production. Sequencesof genes encoding for the partial translation elongation factor,the 3-O-acetyltransferase and a putative reductase wereanalysed by the Maximum Parsimony method. Although thepresent study has focused on a limited number of isolates, thisis the first report that provides evidence of the presence of atleast four species within the FGSC associated with soybean inArgentina: F. graminearum sensu stricto, F. cortaderiae,F. meridionale and F. boothii. In addition, F. graminearumsensu stricto was detected for the first time among Brazilianisolates from soybean
