“…In the Bc Institute's winter wheat breeding program, screening of elite breeding lines for FHB resistance using the spray method of inoculation with Fusarium isolates serves as efficient criterion for final selection for registration purposes [30][31][32]. In the present study, an alternative inoculation method for screening FHB resistance in wheat, known as deployment of Fusarium-infected maize stalks, was compared with the standard spray method and natural infection.…”

One of the most severe winter wheat (Triticum aestivum L.) diseases is Fusarium head blight (FHB). It is believed that selection for resistance to FHB is better in high disease pressure environments, for which various methods of artificial inoculation are used. The standard spray method of artificial inoculation is believed to be technically demanding and labour intensive. Therefore, scattering Fusarium-infected maize stalks onto trial plots after wheat emergence is suggested as a suitable alternative. The aim of this study was to compare the mean values and heritability of the visual rating index (VRI) and the percentage of Fusarium-damaged kernels (FDK) between the two abovementioned methods of artificial inoculation and natural infection, and to determine the phenotypic correlations between the three methods for the studied traits. The achieved levels of VRI and FDK were comparable for the two methods of artificial inoculation and considerably lower under natural conditions. Heritability for VRI ranged over four years from 0.68 to 0.91 for the spray method, from 0.73 to 0.95 for the infected maize stalks, and from 0.26 to 0.65 for natural infection, whereas for FDK it ranged from 0.56 to 0.85, 0.38 to 0.83, and 0.11 to 0.44 for the three inoculation methods, respectively. The strong positive correlation between the two applied methods of artificial inoculation for studied traits suggests that scattering infected maize stalks could serve as a reliable supplement for the technically and labor-intensive spray method of artificial inoculation.

“…Since its first description in 1900 (Bagga 2008), fusarium head blight (FHB) has been one of the most destructive fungal diseases, which reduces crop germination and yield, resulting in extensive reduction (Xin et al 2005) in the production and quality of wheat, barley, and other small-grain cereals worldwide (Wang et al 2007). It is primarily caused by several species of the soil-borne fungal genus Fusarium (Yoshida 2012), which produce mycotoxins, such as deoxynivalenol (DON) (Xu et al2018), nivalenol (NIV), and zearalenone (ZEA) (Tomasovic et al 2007), that contaminate grains. DON and its type B trichothecene derivatives, which are mainly produced by F. graminearum, pose a chronic threat to cereal grain production that can ultimately lead to carcinogenicity, neurotoxicity, and reproductive and developmental toxicity to humans and animals (Tan et al 2012).…”

Fusarium head blight (FHB), a destructive fungal disease that can cause damage to various crops and reduce yield and quality, is primarily caused by several species of the soil-borne fungal genus Fusarium, which produce mycotoxins that contaminate grain and may cause various severe chronic diseases in humans and livestock. In recent years, Bacillus spp. have been reported as good producer of antifungal antibiotics against FHB. This study aimed to explore the potential role of a newly identified Bacillus strain, designated as CU-XJ-9, against FHB. This strain, which was isolated from traditional Chinese fermented food, was identified as Bacillus siamensis and confirmed to produce lipopeptide biosurfactants, which according to the analysis by quadrupole time-of-flight tandem mass spectrometry (Q-TOF-MS/MS) may belong to the iturin lipopeptide family. The isolated antifungal compounds, at 100 μg/mL, completely inhibited the germination of conidia. Observation of the effects of the isolated antifungal compounds on the mycelia of F. graminearum by scanning electron microscopy revealed obvious nodes in the middle of the mycelia and destroyed mycelial structures, and these changes became more pronounced with increasing dose. Overall, this study provides important information about the ability of Bacillus siamensis to produce lipopeptide biosurfactants, which showed significant antagonistic activity against F. graminearum.

“…The contaminated grain with high levels of DON is toxic to livestock and humans (McMullen et al 1997;Jones and Mirocha 1999) thus increasing the economic loss. Fusarium head blight is economically one of the most serious fungal diseases of wheat in many regions of the world (Tomasovic et al 2007). In recent years, FHB remains endemic in Europe, North America, and Asia, especially in China under favorable environmental conditions.…”

Fusarium head blight (FHB, caused by Fusarium graminearum) is a severe disease which threatens the yield and quality of harvested grain products, and hence causes major economic losses in wheat (Triticum spp.) and other small grain cereals. One of the infection routes for the pathogen is believed to be through the extruded anther. In order to study the role of the anther on FHB infection, FHB resistance was measured among wheat (Triticum aestivum L.) cultivars with non-extruded infertile anthers in cytoplasmic male sterile (CMS) lines and with extruded fertile anthers in their alloplasmic maintainer lines, and in an unrelated restorer line. We artificially inoculated the lines with F. graminearum (isolate NE 90) at 1.0 × 10 5 or 2.0 × 10 5 spores mL -1 for 72 or 96 hours. The results indicated that CMS cultivars were significantly more resistant than the maintainer and restorer cultivars. As the CMS lines differed from the maintainer lines by cytoplasm, anther health, anther extrusion, and seed set, additional experiments are needed to determine the role of each factor in infection. However, this research indicates that fertile anthers most likely are an important part of the infection pathway and of susceptibility to FHB.
