| identification of new galactose oxidase genes in fusarium spp. | galactose oxidase (go) converts galactose to an aldehyde and has several biotechnological applications, including cancer diagnosis. it is mainly produced by fusarium austroamericanum but is also produced by fusarium acuminatum and by isolates of the fusarium graminearum and gibberella fujikuroi complexes. the f. austroamericanum go gaoa gene has been cloned, but the go genes from other secreting species have not been characterized. problems associated with the f. austroamericanum go such as high ... | 2010 | 21077113 |
| 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 |
| regional differences in species composition and toxigenic potential among fusarium head blight isolates from uruguay indicate a risk of nivalenol contamination in new wheat production areas. | members of the fusarium graminearum species complex (fgsc) are the primary cause of fusarium head blight (fhb) of wheat, and frequently contaminate grain with trichothecene mycotoxins that pose a serious threat to food safety and animal health. the species identity and trichothecene toxin potential of 151 fgsc isolates collected from wheat in uruguay were determined via multilocus genotyping. although f. graminearum with the 15adon trichothecene type accounted for 86% of the isolates examined, f ... | 2013 | 23856007 |
