Fusarium equiseti and Fusarium acuminatum are toxigenic species that contaminate cereal crops from diverse climatic regions. They are common in Spanish cereals. The information available on their phylogenetics and toxigenic profiles is, however, insufficient to assist risk evaluation. In this work, phylogenetic analyses were performed using partial sequences of the translation elongation factor...

objective: fusarium species are prevalent contaminants of foodstuffs and agricultural crops.  they produce fumonisins, which are carcinogenic mycotoxins. the present study has evaluated maize and wheat samples from ten provinces in iran that were contaminated with fusarium species. special attention was paid to the ability of the isolates to produce fumonisin b1 (fb1) as a public health hazard....

Thirty seven species of Fusarium were evaluated for their ability of producing extracellular enzymes using chromogenic medium containing substrates such as starch, cellobiose, CM-cellulose, xylan, and pectin. Among the tested species Fusarium mesoamericanum, F. graminearum, F. asiaticum, and F. acuminatum showed high β-glucosidase acitivity. Xylanase activity was strongly detected in F. prolife...

A new aporphine alkaloid, 7-epi-duguetine (1) together with one known alkaloid, dicentrinone (2), and four known flavonoids, quercetin 3,7-dimethyl ether 3′-O-α-L-rhamnopyranosyl-(12)-β-D-glucopyranoside (3), galangin 5-methyl ether (4), 5,7-dimethoxy-3-hydroxyflavone (5), and 3,5,7-trimethoxyflavone (6), were isolated from the leaves of Dasymaschalon acuminatum, a new plant species which has ...

Crown disease (CD) is infecting oil palm in the early stages of the crop development. Previous studies showed that Fusarium species were commonly associated with CD. However, the identity of the species has not been resolved. This study was carried out to identify and characterize through morphological approaches and to determine the genetic diversity of the Fusarium species. 51 isolates (39%) ...

Nine different Fusarium species were isolated from Acacia koa seeds, seedpods, seedling stem and root tissues, rhizosphere soil and soil surrounding roots of diseased trees. Fusarium oxysporum, the cause of koa dieback and wilt, was not isolated from seeds or seedpods but was found most commonly on roots and soil near diseased koa seedlings. Fusarium subglutinans was the most common species iso...
