“…Control of B. sorokiniana in the seeds of wheat could be achieved through the use of resistant cultivars, fungicides, seed treatment, or biocontrol agents. Cultivars can react differently to seed infection due to several factors such as non-compatibility to infection, restricted pathogen invasion of the seed parts due to inhibitors, or reduced testa permeability (Gannibal, 2018;Singh et al, 2019). In a study by Li et al (2014) on 403 wheat genotypes in the North China Plain, 62.5% of the genotypes were classified as susceptible, while 37.5% were resistant to black point disease.…”

“…In addition, some reports indicated the association of Alternaria alternata , Fusarium spp., and Penicillium spp. with wheat seeds developing black point symptoms ( Al-Sadi and Deadman, 2010 ; Gannibal, 2018 ; Ghosh et al., 2018 ; Xu et al., 2018b ; Li et al., 2019b ; Li et al., 2020 ). Black point has been reported in different parts of the world, including China, Argentina, Oman, Australia, India, and Bangladesh ( Rashid et al., 1992 ; Sisterna and Sarandon, 2005 ; Al-Sadi and Deadman, 2010 ; Poole et al., 2015 ; Xu et al., 2018b ).…”

Wheat is among the ten top and most widely grown crops in the world. Several diseases cause losses in wheat production in different parts of the world. Bipolaris sorokiniana (teleomorph, Cochliobolus sativus) is one of the wheat pathogens that can attack all wheat parts, including seeds, roots, shoots, and leaves. Black point, root rot, crown rot and spot blotch are the main diseases caused by B. sorokiniana in wheat. Seed infection by B. sorokiniana can result in black point disease, reducing seed quality and seed germination and is considered a main source of inoculum for diseases such as common root rot and spot blotch. Root rot and crown rot diseases, which result from soil-borne or seed-borne inoculum, can result in yield losses in wheat. Spot blotch disease affects wheat in different parts of the world and cause significant losses in grain yield. This review paper summarizes the latest findings on B. sorokiniana, with a specific emphasis on management using genetic, chemical, cultural, and biological control measures.

“…Fusarium and Alternaria interactions are described as complex, depending on the type of mycotoxins involved in the competition [ 33 , 35 , 36 ]. Usually, a considerably increased mycotoxin production is shown with simultaneous infection with Alternaria and Fusarium [ 32 , 37 , 38 ].…”

“…Xu et al [ 31 ] concluded that the observed increase in mycotoxins under mixed inoculations could be due to the fungi’ stress during competition. Gannibal [ 35 ] studied the competition of Alternaria with other fungal genera, including fusaria, and observed that the species F. langsethiae , F. tricinctum , and F. graminearum grew faster while suppressing the growth of Alternaria . Another study by Xu et al [ 39 ] also concluded that fusaria usually reduce the other fungi’ abundance in wheat-ears, which leads to a strong change in the fungal community structure.…”

Co-Cultivation of Fusarium, Alternaria, and Pseudomonas on Wheat-Ears Affects Microbial Growth and Mycotoxin Production

et al. 2021

Mycotoxigenic fungal pathogens Fusarium and Alternaria are a leading cause of loss in cereal production. On wheat-ears, they are confronted by bacterial antagonists such as pseudomonads. Studies on these groups’ interactions often neglect the infection process’s temporal aspects and the associated priority effects. In the present study, the focus was on how the first colonizer affects the subsequent ones. In a climate chamber experiment, wheat-ears were successively inoculated with two different strains (Alternaria tenuissima At625, Fusarium graminearum Fg23, or Pseudomonas simiae Ps9). Over three weeks, microbial abundances and mycotoxin concentrations were analyzed and visualized via Self Organizing Maps with Sammon Mapping (SOM-SM). All three strains revealed different characteristics and strategies to deal with co-inoculation: Fg23, as the first colonizer, suppressed the establishment of At625 and Ps9. Nevertheless, primary inoculation of At625 reduced all of the Fusarium toxins and stopped Ps9 from establishing. Ps9 showed priority effects in delaying and blocking the production of the fungal mycotoxins. The SOM-SM analysis visualized the competitive strengths: Fg23 ranked first, At625 second, Ps9 third. Our findings of species-specific priority effects in a natural environment and the role of the mycotoxins involved are relevant for developing biocontrol strategies.

“…Most cereals are colonized by small-spore species: A. arborescens, A. alternata, A. tenuissima, and A. infectoria. The most widely spread information is about the distribution of the latter three species in Argentina (Andersen et al, 2015), Italy (Logrieco et al, 2009), Norway (Kosiak et al, 2004), Germany (Müller & Korn, 2013), and Russia (Gannibal, 2018). Seed treatment is necessary for overcoming the harmful effects of seed and soil infection and for rapid germination.…”

The microbiota of winter wheat seeds from the North-East of Ukraine was studied by a biological method. Its considerable variability is established over three years (2017–2019). The effect of the treatment agents on most microorganisms of wheat seed microbiota in Ukraine, rather than on its genera and species, is shown. It has been proven that fungicides deleted some species and did not affect the development of others. Chemicals replaced some species or genera of fungi with others or even other microorganisms. Biological seed treatment (Phytosporin-M) has caused less microbiota change than chemical treatment (Maxim 0.25 FS, Rostock, Kinto Duo). Fungicides have replaced the dominance of Alternaria spp. (2017 – 57.8%, 2018 – 63.5%) for the dominance of yeast (Rostock – 54%) and Aureobasidium pullulans (Maxim 0.25 FS – 84.2%) in 2017, bacteria (Maxim 0.25 FS – 72.3%, Rostock – 53.8%) – in 2018. A. pullulans dominated in the microbiota of winter wheat seeds in 2019. The highest amount of A. pullulans was noted for the treatment of seeds by Phytosporin-M (85.9%). The biological seed treatment reduced the amount of Nigrospora spp. and Alternaria spp. Several times (3 and 5, respectively), chemical agents did not give Nigrospora spp. germination reduced the amount of A. pullulans, Alternaria spp. in 2019. Maxim 0.25 FS, Rostock 50%, and Kinto Duo delayed seed germination and seedling development on agar medium and soil, whereas Phytosporin-M – on the contrary, promoted the growth of seedlings and significantly exceeded control.
