| Summary: | Fusarium head blight (FHB) is one of the most important diseases that occurs in cereal
regions worldwide and causes serious economic damage. This disease can be caused by
several Fusarium species with Fusarium graminearum sensu stricto being the most common
pathogen isolated from several crops. The aim of this study was to report the occurrence
of F. graminearum sensu stricto on rye grains collected from field samples in Argentina
and to determine the potential ability to produce deoxynivalenol (DON), nivalenol (NIV)
and zearalenone (ZEA). Based on morphological characteristics, the isolate was identified
as F. graminearum sensu stricto. To confirm molecularly, portions of the RED and TRI
genes were sequenced and showed 99% similarity with the F. graminearum sensu stricto
sequences available in the NCBI database. The potential to produce DON, 15-acetyldeoxynivalenol
(15-ADON) and ZEA was determined. Moreover, Koch´s postulates were
carried out. To our knowledge, this is the first report of F. graminearum sensu stricto
associated with rye kernels in Argentina. |
