“…Nevertheless, both species are common in Central and Northern Europe. The frequency of Fusarium species on cereals in Poland varies because of the significant variation in weather conditions [5,13,15,28].…”

“…However, Goliński et al [28] found F. poae (64%), F. tricinctum (15%), F. avenaceum (8%), F. culmorum (6%) and F. graminearum (4%) as the most common species infecting wheat heads in Poland. High incidence of F. avenaceum in Dębina ( Table 2) was related probably to the geographical locationcooler weather conditions are usually favorable for this species [10].…”

Toxigenic Fusarium species infecting wheat heads in Poland

et al. 2013

Toxigenic Fusarium species are common pathogens of wheat and other cereals worldwide. In total, 449 wheat heads from six localities in Poland, heavily infected with Fusarium during 2009 season, were examined for Fusarium species identification. F. culmorum was the most common species (72.1% on average) with F. graminearum and F. avenaceum the next most commonly observed, but much less frequent (13.4 and 12.5% respectively). F. cerealis was found in 1.8% of all samples, and F. tricinctum was found only in one sample (0.2%). Subsequent quantification of the three major mycotoxins (deoxynivalenol, zearalenone and moniliformin) in grain and chaff fractions with respect to associated prevailing pathogen species uncovered the following patterns. Moniliformin (MON) was found in low amounts in all samples with F. avenaceum present. In contrast, deoxynivalenol (DON) and zearalenone (ZEA) were the contaminants of F. culmorum- and F. graminearum-infected heads. The highest concentration of DON was recorded in grain sample collected in Radzików (77 µg g−1). High temperatures in Central Poland during July and August accompanied with high rainfall in July were responsible for this high DON accumulation. Trichothecene, zearalenone, enniatin and beauvericin chemotypes were identified among 21 purified isolates using gene-specific PCR markers.

“…Fusarium avenaceum has been reported as one of the most frequently isolated Fusarium species from cereals in Norway Langseth et al, 1997), Finland (Yla-Mattila et al, 2002, Poland (Golinski et al, 1996), England (Parry et al, 1995) and Germany (Schu¨tze et al, 1997). Because information on the infection process of F. avenaceum in wheat spikes is limited, penetration and colonization of wheat spikes by F. avenaceum was examined in this study by SEM and TEM.…”

“…Epidemics of FHB result in a significant yield reduction and low quality of grains (Boyacioglu and Hettiarachchy, 1995), but also in contamination of grains with mycotoxins produced by the pathogens (Snijders and Perkowski, 1990;Golinski et al, 1996). The mycotoxins have been shown to be harmful to human and animal health (Desjardins and Hohn, 1997).…”

Infection of wheat spikes by Fusarium avenaceum and alterations of cell wall components in the infected tissue

2005

The infection process of Fusarium avenaceum on wheat spikes and the alteration of cell wall components in the infected host tissue were examined by means of electron microscopy and cytochemical labelling techniques following spray inoculation at growth stage (GS) 65 (mid-flowering). Macroconidia of the pathogen germinated with one to several germ-tubes 6-12 h after inoculation (hai) on host surfaces. The germ-tubes did not penetrate host tissues immediately, but extended and branched on the host surfaces. Hyphal growth on abaxial surfaces of the glume, lemma and palea was scanty 3-4 days after inoculation (dai) and no direct penetration of the outer surfaces of the spikelet was observed. Dense mycelial networks formed on the inner surfaces of the glume, lemma, palea and ovary 36-48 hai. Penetration of the host tissue occurred 36 hai by infection hyphae only on the adaxial surfaces of the glume, lemma, palea and upper part of ovary. The fungus penetrated the cuticle and hyphae extended subcuticularly or between the epidermal wall layers. The subcuticular growth phase was followed by penetration of the epidermal wall, and hyphae spread rapidly inter-and intracellularly in the glume, lemma, palea and ovary. During this necrotrophic colonization phase of the wheat spike, a series of alterations occurred in the host tissues, such as degeneration of cytoplasm and cell organelles, collapse of host cells and disintegration of host cell walls. Immunogold labelling techniques showed that cell walls of spike tissues contained reduced amounts of cellulose, xylan and pectin near intercellular hyphae or infection pegs compared to walls of healthy host tissues. These studies suggest that cell wall degrading enzymes produced by F. avenaceum facilitated rapid colonization of wheat spikes. The different penetration properties of abaxial and adaxial surfaces of the spikelet tissues as well as the two distinct colonization strategies of host tissues by F. avenaceum are discussed. The penetration and colonization behaviour of F. avenaceum in wheat spikelets resembled that of F. culmorum and F. graminearum, although mycotoxins produced by F. avenaceum differed from those of the latter two Fusarium species.

“…Biosynthesis of toxic secondary metabolites (including trichothecene myocotoxins) and their accumulation in kernels and various tissues of cereals [24] is one of the factors differing aggressiveness of pathogenic strains [5]. Moniliformin is produced by F. avenaceum and is accumulated in significant amounts in wheat kernels, often in co-occurrence of other toxic metabolites rendering situation more hazardous in animal and human health [7]. In Poland, natural contamination of cereals by Fusarium mycotoxins was reported [4,6,8,21,25].…”

In South-Eastern region of Poland (near Lublin), where frequency of scab (fusariosis) is much higher than in other parts of the country, during harvest of 1993 kernels of 25 winter wheat cultivars were collected. On the basis of morphological studies Fusarium graminearum was found in 42% of investigated samples while other fungi appeared less frequently: F. nivale and F. poae (35%), F. avenaceum (31%) and F. culmorum (12%). Chemical analysis (by HPLC) revealed that the tested cultivars were contaminated with deoxynivalenol (96% of investigated samples), its acetyl derivatives (48%), nivalenol (76%) and moniliformin (28%). The average levels of the metabolite concentrations were as follows: 104; 16; 97; and 63 micrograms/kg, respectively. Co-occurrence of 2 toxic metabolites was found in the following percentage of the positive samples: deoxynivalenol and nivalenol (72%), deoxynivalenol and moniliformin, as well as nivalenol and moniliformin (24%). Usually (71-83% of contaminated samples) mycotoxins were accumulated in the concentration range > or = 10, < 100 micrograms/kg.
