“…In addition, there are differences in the activity of these bacteria against phytopathogenic fungi. In the work of M. Pan et al [22] Bacillus megaterium (BM1) and Bacillus subtilis (BS43, BSM0 y BSM2) were isolated from wheat seeds. They had a high antagonistic activity against Fusarium graminearum.…”

The aim of the study was to investigate the peculiarities of microbiome and seed bacterial endophytes isolated from different varieties of spring wheat grown in different areas of Eurasia (European part of Russia (Volga region), countries of Central Asia). The main method of the microbiome studies was PCR. Isolation of bacterial endophytes from the seeds allowed estimating their count and evaluating their activity towards Fusarium oxysporum. Quantitative analysis of the microbiome was performed on seeds from different spring wheat varieties (genotypes) obtained from the Russian Federation, the Republic of Kazakhstan and the Republic of Tadzhikistan. The differences in the bacterial endophytic microflora of the seeds and their activity towards Fusarium oxysporum were established. The seeds grown in Central Asia have higher count of both total microbiome and bacterial endophytes active against phytopathogens than the seeds grown in Volga region of the Russian Federation. Differences in the species composition of seed endophytic bacteria were established. Active strains of seed endophytic bacteria obtained from Tajikistan belonged to the species Bacillus jeuvensis. Active strains of bacterial endophytes were isolated from spring wheat seeds grown in Tadzhikistan for the development of highly potential biofungicides. The study results confirmed that seed microbiome depends on variety and the area of cultivation. The materials of the study can be useful for the evaluation of the seeds in the breeding of spring wheat and in the search for new biological agents for biofungicides development.

“…Likewise, bacterial strains such as Bacillus amyloliquefaciens FLN13 and Lactobacillus plantarum SLG17 have reduced Fusarium disease index up to 50% when inoculated simultaneously at flowering (Baffoni et al 2015). B. megaterium BM1 showed similar results in South America (Pan et al 2015). Also, Pseudomonas fluorescens LY1-8 showed reduced FCR and FHB severity by half in field trials when sprayed at flowering (Wang et al 2015).…”

World cereal production faces the challenge of increasing productivity while reducing its environmental footprint. Diseases like Fusarium head blight that reduce yield and quality of the harvest are controlled mainly with agricultural practices and fungicides. These measures have been shown to be inefficient or unsustainable. After reviewing the current knowledge about Fusarium fungi–cereal interactions, this chapter describes how progress can be built over current agricultural practices in integrated pest management plans. The methods described include increasing genetic resistance by exploiting the full extent of the advantages of new technologies, as well as looking for new fungicide molecules that aim for specific fungal metabolic pathways during infection at an early stage. The chapter addresses the disease cycle of Fusarium head blight, host–pathogen interactions, genetic resistance, the role of mycotoxins, the impact of the disease on yields and loss of crop quality, and techniques of disease management. Finally, the chapter looks ahead to future research trends in this area.

“…In many cases, the biocontrol bacteria found in association with cultivated plants have an increased antagonistic potential against those phytopathogens specific for the same host. For example, some endophytic bacterial strains, found in wheat plants, expressed biocontrol activity against Fusarium graminearum responsible for the fusarium head blight and mycotoxins production in wheat [11]. Similar aspects reveal a better antagonistic efficacy of biocontrol bacteria against those pathogens infecting the same plant organs, were beneficial bacteria are habituated to survive.…”
