“…The dominant trichothecene genotype in the populations analyzed herein was 15-ADON, which is consistent with results from earlier studies of strains from Uruguay (Pan et al, 2013;Umpiérrez-Failache et al, 2013) and with previous analyses of F. graminearum s.s. isolates from wheat in Brazil (Astolfi et al, 2012). In Argentina, although 15-ADON seems to dominate among F. graminearum s.s. isolates, a DON/NIV genotype/chemotype has also been found in wheat and barley.…”

“…Two NIV isolates were also detected by Pan et al . () in Uruguay, but these isolates were identified as F. graminearum by AFLP analysis. Isolates with the 3‐ADON genotype have also been identified in a small proportion of FGSC isolates from wheat produced in Argentina (Alvarez et al ., ) and Uruguay (Umpiérrez‐Failache et al ., ).…”

“…For example, Reynoso et al (2011) found that most F. graminearum isolates in Argentina were of the 15-ADON genotype, although some amplified for both DON/NIV genotypes. Two NIV isolates were also detected by Pan et al (2013) in Uruguay, but these isolates were identified as F. graminearum by AFLP analysis. Isolates with the 3-ADON genotype have also been identified in a small proportion of FGSC isolates from wheat produced in Argentina (Alvarez et al, 2009) andUruguay (Umpi errez-Failache et al, 2013).…”

“…However, surveys on wheat and barley crops grown in South America identified five other species affecting these crops: F. asiaticum , F. austroamericanum , F. brasilicum , F. cortaderiae and F. meridionale . While in Argentina FHB in wheat seems to be caused exclusively by F. graminearum (Alvarez et al ., ; Reynoso et al ., ), other species of the complex occur in Brazil and Uruguay in a relatively small proportion (Scoz et al ., ; Astolfi et al ., , ; Pan et al ., ; Umpiérrez‐Failache et al ., ; Del Ponte et al ., ).…”

Members of the Fusarium graminearum species complex (FGSC), such as F. graminearum and F. asiaticum, are the main cause of fusarium head blight (FHB) of wheat and barley worldwide. In this study, 117 FGSC isolates obtained from commercial barley grain produced in Argentina (n = 43 isolates), Brazil (n = 35), and Uruguay (n = 39) were identified to species and trichothecene genotypes, and analysed using amplified fragment length polymorphism (AFLP) and sequence‐related amplified polymorphism (SRAP) markers. In addition, reductase (RED) and trichothecene 3‐O‐acetyltransferase (Tri101) were sequenced for a subset of 24 isolates. The majority of the isolates (n = 103) were identified as F. graminearum, which was the only species found in Argentina. In Uruguay, only one F. cortaderiae isolate was found among F. graminearum isolates. In Brazil, F. graminearum also dominated the collection (22/35), followed by F. meridionale (8/35), F. asiaticum (2/35), F. cortaderiae (2/35) and F. austroamericanum (1/35). Species were structured by trichothecene genotype: all F. graminearum were of the 15‐acetyldeoxynivalenol (ADON), F. meridionale, F. asiaticum and F. cortaderiae were of the nivalenol (NIV), and F. austroamericanum was of the 3‐ADON genotype. Both AFLP and SRAP data showed high levels of genetic variability, which was higher within than among countries. Isolates were not structured by country of origin. SRAP analysis grouped F. graminearum in a separate cluster from the other species within the complex. However, AFLP analysis failed to resolve the species into distinct clades with partial clustering of F. meridionale, F. austroamericanum, F. asiaticum and F. graminearum isolates.

“…Gale et al (2011) observed that NIV, 15-ADON and 3-ADON genotype populations obtained from wheat varied according to the geographic origin in the USA. In South America (Uruguay and Brazil) F. graminearum isolates of the 15-ADON genotype were reported to predominate in wheat (Scoz et al, 2009;Pan et al, 2013).…”
