podział geograficzny - Opis:
- The Fusarium graminearum species complex (FGSC) consists of phylogenetically distinct pathogenic species. Isolates from various regions display genetic variety worldwide. Three type B trichothecene chemotypes have been identified within the FGSC: nivalenol, 3-deoxynivalenol and 15-deoxynivalenol. The variations in morphological, genetic and virulence traits of FGSC fungi can be attributed mainly to their geographic boundaries. The geographic range of host plants, type of farming system and weather conditions also influence the prevalence of FGSC taxa. The geographic distribution of FGSC members may reflect not only their chemotype but also adaptive traits. While 15-acetyl-deoxynivalenol (15-ADON) chemotype is prevalent in most of Europe, the 3-acetyl-deoxynivalenol (3-ADON) chemotype has achieved greater prevalence in parts of North America. The Asian species F. asiaticum has spread into new territories. Isolates of F. asiaticum have been identified in North America and Europe, and the species has recently been reported to be infecting cereal crops in South America. The occurrence of numerous members of the FGSC in those regions and the introduction of F. asiaticum into new areas raise significant food safety concerns and indicate the need for monitoring mycotoxin concentrations in harvested grain.
