Abstract

Fusarium is globally one of most important genera of fungi, causing an array of plant diseases, producing mycotoxins and adversely affecting human health. Some Fusarium species are associated with grasses, as saprophytes, endophytes or pathogens. A study was carried out on the distribution and diversity of Fusarium species associated with non-agricultural grasses, maize, sorghum and millet in Hungary. Grasses (Poaceae), both agricultural and wild, are important hosts of pathogenic Fusarium species. Little is known, however, about endophytic fusaria in wild grasses in Hungary.The aim of this paper was to present data on the occurrence of fusaria on grass species collected from wild populations. A total of 106 plants belonging to 43 different grass species were collected in different locations in Hungary, and 11 different Fusarium species were isolated from the stems of 62.3% of the plant samples. The most common species were F. compactum (19.1%), F. equiseti (16.2%) and F. graminearum (14.7%). Wild grasses are a rich source of endophytic Fusarium isolates for the production of metabolites with antimicrobial and anticancer activity. This is the first report on the diversity of endophytic Fusarium associated with grasses in Hungary.
