“…It is controversial whether F. temperatum is a fumonisin producer. In Belgium, Scauflaire et al (2012) found that one out of eleven isolates produced low levels of FB 1 . In Argentina, higher ratio of F. temperatum isolates (10/38) were identified as low fumonisin producers (max.…”

“…Fusarium temperatum is a newly described species first found on maize in Belgium. It is closely related to F. subglutinans, but showed a different mycotoxin profile, especially for beauvericin production (Fumero et al, 2015;Scauflaire et al, 2012).…”

In recent years increasing demands and the relatively low-care cultivation of the crop have resulted in an enormous expansion of the acreage of maize in China. However, particularly in China, Fusarium ear rot forms an important constraint to maize production. In this study, we showed that members of both the Fusarium fujikuroi species complex (FFSC) and the Fusarium graminearum species complex are the causal agents of Fusarium ear rot in the main maize producing areas in China. Fumonisin producing Fusarium verticillioides was the most prevalent species, followed by fumonisin producing Fusarium proliferatum and 15-acetyldeoxynivalenol producing F. graminearum. Both Fusarium temperatum and Fusarium boothii were identified for the first time in the colder regions in China, extending their known habitats to colder environments. Mating type analysis of the different heterothallic FFSC species, showed that both types co-occur in each sampling site suggestive of the possibility of sexual recombination. Virulence tests with F. boothii (from maize) and F. graminearum from maize or wheat showed adaptation to the host. In addition, F. graminearum seems to outcompete F. boothii in wheat-maize rotations. Based on our findings and previous studies, we conclude that wheat/maize rotation selects for F. graminearum, while a wheat/rice rotation selects for F. asiaticum. In contrast, F. boothii is selected when maize is cultivated without rotation. A higher occurrence of F. temperatum is observed on maize in colder climatological regions in China, while Fusarium meridionale seems restricted to mountain areas. Each of these species has their characteristic mycotoxin profile and deoxynivalenol and fumonisin are the potential threats to maize production in Northern China.

Maize (Zea mays L.) is an economically important crop in worldwide. While the consumption of the maize is steadily increasing, the yield is decreasing due to continuous mono-cultivation and infection of soil-borne fungal pathogens such as Fusarium species. Recently, stalk rot disease in maize, caused by F. subglutinans and F. temperatum has been reported in Korea. In this study, we isolated bacterial isolates in rhizosphere soil of maize and subsequently tested for antagonistic activities against F. subglutinans and F. temperatum. A total of 1,357 bacterial strains were isolated from rhizosphere. Among them three bacterial isolates (GC02, GC07, GC08) were selected, based on antagonistic effects against Fusarium species. The isolates GC02 and GC07 were most efficient in inhibiting the mycelium growth of the pathogens. The three isolates GC02, GC07 and GC08 were identified as Bacillus methylotrophicus, B. amyloliquefaciens and B. thuringiensis using 16S rRNA sequence analysis, respectively. GC02 and GC07 bacterial suspensions were able to suppress over 80% conidial germination of the pathogens. GC02, GC07 and GC08 were capable of producing large quantities of protease enzymes, whereas the isolates GC07 and GC08 produced cellulase enzymes. The isolates GC02 and GC07 were more efficient in phosphate solubilization and siderophore production than GC08. Analysis of disease suppression revealed that GC07 was most effective in suppressing the disease development of stalk rot. It was also found that B. methylotrophicus GC02 and B. amyloliquefaciens GC07 have an ability to inhibit the growth of other plant pathogenic fungi. This study indicated B. methylotrophicus GC02 and B. amyloliquefaciens GC07 has potential for being used for the development of a biological control agent.

The genus Fusarium includes numerous toxigenic species that are pathogenic to plants or humans, and are able to colonize a wide range of environments on earth. The genus comprises around 70 well-known species, identified by using a polyphasic approach, and as many as 300 putative species, according to phylogenetic species concepts; many putative species do not yet have formal names. Fusarium is one of the most economically important fungal genera because of yield loss due to plant pathogenic activity; mycotoxin contamination of food and feed products which often render them unaccep for marketing; and health impacts to humans and livestock, due to consumption of mycotoxins. Among the most important mycotoxins produced by species of Fusarium are the trichothecenes and the fumonisins. Fumonisins cause fatal livestock diseases and are considered potentially carcinogenic mycotoxins for humans, while trichothecenes are potent inhibitors of protein synthesis. This chapter summarizes the main aspects of morphology, pathology, and toxigenicity of the main Fusarium species that colonize different agricultural crops and environments worldwide, and cause mycotoxin contamination of food and feed.
