“…These results generally parallel those obtained from isolates of F. oxysporum f. sp. melonis by Moretti et al (2002) who reported that 37 of 44 isolates produced beauvericin, whereas only 11 isolates produced enniatin B, and none produced A and B 1 enniatins . In contrast to the apparent limited potential to produce moniliformin and fumonisins, our results indicate beauvericin and enniatin B cyclohexadepsipeptide mycotoxin production appears to be widespread among members of the FOSC.…”

“…In addition, based on a report of cyclohexadepsipeptide mycotoxin production within the FOSC (Moretti et al, 2002), we investigated the potential of 40 genetically diverse isolates representing 30 STs and nine formae speciales selected from three major clades of the FOSC (O'Donnell et al, 1998b) to produce the beauvericin and enniatin A 1 , B and B 1 in vitro. Beauvericin production was observed in the majority (30 out of 40) of isolates analyzed (Supplementary Table 5), ranging from minute amounts in some isolates to 240 ppm in NRRL 26991 F. oxysporum f. sp.…”

BackgroundFusarium wilt, caused by the fungal pathogen Fusarium oxysporum f. sp. cubense (Foc), is one of the most destructive diseases of banana. Toxins produced by Foc have been proposed to play an important role during the pathogenic process. The objectives of this study were to investigate the contamination of banana with toxins produced by Foc, and to elucidate their role in pathogenesis.Methodology/Principal FindingsTwenty isolates of Foc representing races 1 and 4 were isolated from diseased bananas in five Chinese provinces. Two toxins were consistently associated with Foc, fusaric acid (FA) and beauvericin (BEA). Cytotoxicity of the two toxins on banana protoplast was determined using the Alamar Blue assay. The virulence of 20 Foc isolates was further tested by inoculating tissue culture banana plantlets, and the contents of toxins determined in banana roots, pseudostems and leaves. Virulence of Foc isolates correlated well with toxin deposition in the host plant. To determine the natural occurrence of the two toxins in banana plants with Fusarium wilt symptoms, samples were collected before harvest from the pseudostems, fruit and leaves from 10 Pisang Awak ‘Guangfen #1’ and 10 Cavendish ‘Brazilian’ plants. Fusaric acid and BEA were detected in all the tissues, including the fruits.Conclusions/SignficanceThe current study provides the first investigation of toxins produced by Foc in banana. The toxins produced by Foc, and their levels of contamination of banana fruits, however, were too low to be of concern to human and animal health. Rather, these toxins appear to contribute to the pathogenicity of the fungus during infection of banana plants.

“…Furthermore, BEA was shown to exert a negative inotropic effect (a decrease in cardiac contraction strength) as well as a negative chronotropic effect (a decrease in the frequency of cardiac spontaneous beating activity) (34). Investigation of the Fusarium genus showed that various species produced BEA, including some strains of F. oxysporum isolated from maize and melon (35,36), F. subglutinans isolated from maize ears (37), and F. proliferatum isolated from maize and asparagus (29).…”

There is little information on secondary metabolites produced by Fusaria infecting crop plants other than cereals. Many members of Fusarium genus have the ability to colonise perennial crops with only scarce infection or disease symptoms or with no symptoms at all while still being detectable. Even in case of such asymptomatic infection, significant mycotoxin contamination of the plant tissues is possible. The aim of this study was to characterise the spectrum of Fusarium species isolates obtained from different plant hosts (like asparagus, garlic, pineapple, banana, rhubarb, peppers, rice, maize, wheat, and oncidium) and evaluate their ability to biosynthesize the most common mycotoxins in vitro. Among the F.proliferatum isolates, up to 57 % of them biosynthesized fumonisins at very high mass fractions, amounting to above 1000 μg g-1, while other Fusarium species such as F. verticillioides, F. lactis, F. polyphialydicum, F. concentricum, F. temperatum, and F. fujikuroi formed fumonisins mostly at much lower level. Only F.ananatum and F. oxysporum did not produce these toxins. Co-occurrence of FBs with other mycotoxins [moniliformin (MON) and beauvericin (BEA)] was often observed and it was mainly F. proliferatum species that formed both mycotoxins (0.4 μg g-1 to 41.1 μg g-1 BEA and 0.1 μg g-1 to 158.5 μg g-1 MON).
