| identification and trichothecene genotypes of fusarium graminearum species complex from wheat in taiwan. | fusarium head blight (fhb) of wheat caused by fusarium graminearum species complex (fgsc) is a devastating disease worldwide. the pathogens not only reduce the yield of wheat, but also impact the quality of wheat by contamination with trichothecene mycotoxins. a systematic investigation on the pathogens of fhb in taiwan is lacking. here, molecular and morphological approaches were used to identify species of the taiwanese fgsc isolates and determine their trichothecene genotypes. | 2017 | 28510187 |
| fungal diversity and natural occurrence of deoxynivalenol and zearalenone in freshly harvested wheat grains from brazil. | this study investigated the fungal diversity and presence of deoxynivalenol and zearalenone in 150 samples of freshly harvested wheat grains collected in three regions of brazil (sao paulo, parana, and rio grande do sul). analysis of the mycobiota showed a predominance of alternaria sp., fusarium sp. and epicoccum sp. microdochium nivale (23%), a fungus rarely found in brazilian crops, was detected in sao paulo. four members of the fusarium graminearum species complex were isolated: f. graminear ... | 2016 | 26593513 |
| genetic diversity and trichothecene chemotypes of the fusarium graminearum clade isolated from maize in nepal and identification of a putative new lineage. | on smallholder farms in the foothills of the himalayan mountains in nepal, fungi of the fusarium graminearum clade cause gibberella ear rot of maize and contamination with the 8-ketotrichothecenes nivalenol and deoxynivalenol. previous dna marker analyses of the f. graminearum clade from maize in nepal found a high level of genetic diversity but were limited in detail or scope. the present study incorporated a collection of 251 field strains from a wide geographic distribution in nepal and utili ... | 2010 | 21215953 |
| a molecular based strategy for rapid diagnosis of toxigenic fusarium species associated to cereal grains from argentina. | fusarium species are worldwide causal agents of ear rot in cereals. their toxigenic potential is a health risk for both humans and animals. in argentina, most identification of these fungi has been based on morphological and cross-fertility criteria which are time consuming and require considerable expertise in fusarium taxonomy and physiology. dna based approaches have been reported as rapid, sensitive and specific alternatives to identify the main fumonisin and trichothecene-producing fusarium ... | 2010 | 20965064 |
