“…This change may reflect a regional difference or a chemotype/species shift in recent years. Similar results were reported from Switzerland, where both dimensional and temporal variation of Fusarium composition on maize was observed (Dorn et al, 2009(Dorn et al, , 2011. Temporal variation events were also reported on wheat (Waalwijk et al, 2003;Ward et al, 2008).…”

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.

“…in the fields throughout the three growing seasons, the following major associated mycotoxins might be produced : type B trichothecenes (produced by F. graminearum, F. crookwellense, F. culmorum, F. equiseti, and F. poae), zearalenones (produced by F. graminearum, F. crookwellense, F. culmorum, F. equiseti, and F. sporotrichioides), fusarins (produced by F. graminearum, F. crookwellense, F. culmorum, F. avenaceum, F. poae, F. proliferatum, F. tricinctum, and F. verticillioides), moniliformin (produced by F. avenaceum, F. culmorum, F. temperatum, F. proliferatum, F. tricinctum, F. oxysporum, F. sporotrichioides, and F. subglutinans), beauvericin (produced by F. avenaceum, F. temperatum, F. poae, F. proliferatum, F. oxysporum, and F. sambucinum), enniatins (produced by F. avenaceum, F. temperatum, F. tricinctum, F. oxysporum, F. torulosum, F. lateritium, and F. sambucinum), and type A trichothecenes (F. equiseti, F. poae, F. venenatum, F. sporotrichioides, and F. sambucinum). According to this study, fumonisin producers (F. proliferatum and F. verticillioides) occurred less frequently in Belgian fields, compared to other European countries (Brygoo and Gautier 2007;Goertz et al 2008;Dorn et al 2009). …”

Biodiversity of Fusarium species in ears and stalks of maize plants in Belgium

et al. 2011

In order to investigate the pre-harvest contamination of maize plants by Fusarium species in Belgium, a three-year survey has been performed in five fields in which three hybrids differing in susceptibility to maize stalk rot were sampled at four different physiological stages. An extensive collection of 5,659 Fusarium isolates characterized at the species level was established during the 2005, 2006, and 2007 growing seasons, with a total of 23 different Fusarium species identified to occur on ears and stalks. A high number of plants was already contaminated by Fusarium spp. at the anthesis stage, although no symptoms were visible on ears or on stalks. As the season progressed, the incidence of Fusarium-infected maize plants reached 100% in several fields. At the end of the growing season, the most frequently isolated species in maize ears were F. graminearum, sometimes associated with F. avenaceum, F. crookwellense, F. culmorum, F. poae, and F. temperatum, a new species recently described on maize. The predominant Fusarium species detected in stalks at the end of the growing season were F. graminearum and F. crookwellense, often associated with F. culmorum and F. temperatum. Year-to-year variability observed for the incidence of F. graminearum can most likely be associated with differences in climatic conditions among the three years.

“…It was also grouped in the F. sambucinum species complex by phylogenetic analysis (O'Donnell et al, 2013). F. venenatum is not known to inhabit soils but is rather known because of its use to produce a mycoprotein for human consumption (Wiebe, 2002); however it can be found in association with plant debris (Dorn et al, 2009;Postic et al, 2012). Similarly F. sambucinum identified in soil E has occasionally been isolated from other soils (Steinkellner and Langer, 2004;Saremi and Fig.…”
