“…For example, sixteen F. langsethiae strains identified in Belgium showed white mycelium with a light yellow pigment on PDA [39]. According to A. Lukanowski and C. Sadowski [10], the sparse mycelium of strains identified in Poland was whitish or pinkish white. Follow to the colleagues who studied the pigment differentiation of F. langsethae strains originating from the UK, possess one of three colony colours; white, orange or purple [40].…”

Analysis of 49 strains of F. langsethiae originating from northern Europe (Russia, Finland, Sweden, UK, Norway, and Latvia) revealed the presence of spontaneous auxotrophic mutants that reflect natural intraspecific diversity. Our investigations detected that 49.0% of F. langsethiae strains were auxotrophic mutants for biotin, and 8.2% of the strains required thiamine as a growth factor. They failed to grow on vitamin-free media. For both prototrophic and auxotrophic strains, no growth defect was observed in rich organic media. Without essential vitamins, a significant reduction in the growth of the auxotrophic strains results in a decrease of the formation of T-2 toxin and diacetoxyscirpenol. In addition, all analysed F. langsethiae strains were distinguished into two subgroups based on PCR product sizes. According to our results, 26 and 23 strains of F. langsethiae belong to subgroups I and II respectively. We determined that the deletion in the IGS region of the rDNA of F. langsethiae belonging to subgroup II is linked with temperature sensitivity and causes a decrease in strain growth at 30 °C. Four thiamine auxotrophic strains were found in subgroup I, while 21 biotin auxotrophic strains were detected in subgroups II. To the best of our knowledge, the spontaneous mutations in F. langsethiae observed in the present work have not been previously reported.

“…but this species exhibits low pathogenicity, and it usually does not reduce wheat yields (Vogelgsang et al 2008;Wachowska et al 2013). Fusarium langsethiae Torp & Nirenberg, which had not been reported from Eastern Europe in the past, has also recently been isolated from wheat (Łukanowski and Sadowski 2008). In Finland the predominant species was Fusarium avenaceum (Fr.)…”

The effect of the biological control agent Aureobasidium pullulans (de Bary) G. Arnaud on the development of Fusarium head blight (FHB) on winter wheat and kernel contamination with fungi of the genera Fusarium, Acremonium, Cladosporium and Penicillium was analyzed in a greenhouse experiment. Scanning electron microscopy was used to evaluate the distribution of A. pullulans cells and aggregates on wheat kernels, infection structures of Fusarium culmorum (W.G. Smith) Sacc and the antagonist-pathogen interactions. Biological control with A. pullulans reduced FHB severity by 21.67 % and improved grain filling by 5.02 %, compared with the control treatment. The survival of A. pullulans was good (to 31 cells per kernel), in particular on the surface and in the crease of kernels, including in pathogen-inoculated wheat plants. A. pullulans cells firmly adhered to F. culmorum hyphae, and damaged them. In most cases, autochthonous communities of filamentous fungi of the genera Acremonium and Penicillium developed at a slower rate after kernel inoculation with the pathogen.
