“…NSY50 application may systemically affect plant-soil interactions by increasing soil richness and the diversity and the abundance of certain BCAs, such as the genera Bacillus, Actinobacteria, Streptomyces, Actinospica, Catenulispora and Pseudomonas. These genera are known to have an antagonistic action against pathogens 14 19 20 56 57 , thus reducing cucumber Fusarium wilt and stimulating cucumber growth. Furthermore, the rhizospheres of cucumber plants subjected to NSY50 + FOC treatment showed a lower abundance of Fusarium than the rhizospheres of cucumber plants grown with FOC.…”

“…In another study, P. polymyxa strains were shown to cause antibiosis and produce polymyxins, colistin and hydrolytic enzymes, which play important roles in the biocontrol of plant pathogens 16 17 18 . Furthermore, the microbial community of the rhizosphere is primary factor determining plant health 19 , and also thought to be distinctly important to the biological, chemical and physical processes that are essential to maintain a healthy and stable microenvironment and to successfully suppress various diseases 20 21 22 . In turn, the soil enzymatic activities, plant species, and soil type also influence the composition of the microbial community, contributing to plant disease suppression 23 24 25 26 .…”

Paenibacillus polymyxa (P. polymyxa) NSY50, isolated from vinegar residue substrate, suppresses the growth of Fusarium oxysporum in the cucumber rhizosphere and protects the host plant from pathogen invasion. The aim of the present study was to evaluate the effects of NSY50 application on cucumber growth, soil properties and composition of the rhizospheric soil microbial community after exposure to Fusarium oxysporum. Bacterial and fungal communities were investigated by Illumina sequencing of the 16S rRNA gene and the internal transcribed spacer (ITS) regions (ITS1 and ITS2). The results showed that NSY50 effectively reduced the incidence of Fusarium wilt (56.4%) by altering the soil physico-chemical properties (e.g., pH, Cmic, Rmic, total N and Corg) and enzyme activities, especially of urease and β-glucosidase, which were significantly increased by 2.25- and 2.64-fold, respectively, relative to the pathogen treatment condition. More specifically, NSY50 application reduced the abundance of Fusarium and promoted potentially beneficial groups, including the Bacillus, Actinobacteria, Streptomyces, Actinospica, Catenulispora and Pseudomonas genera. Thus, our results suggest that NSY50 application can improve soil properties, shift the microbial community by increasing beneficial strains and decreasing pathogen colonization in the cucumber rhizosphere, and reduce the occurrence of cucumber Fusarium wilt, thereby promoting cucumber growth.

“…Different beneficial microorganisms interact and this microbial crosstalk has important consequences for plant health (Cameron, Neal, van Wees, & Ton, ; Shtark, Borisov, Zhukov, & Tikhonovich, ). Palmieri, Vitullo, de Curtis, and Lima () showed that a microbial consortium of four beneficial rhizobacteria controls F. solani and F. oxysporum of chickpea more efficiently than each bacterial isolate on its own. The control of red crown rot in soybean ( Glycine max ) is more efficient when coinoculating AMF and rhizobia compared with single inoculations with either symbiont (Gao et al, ).…”

Root and foot diseases severely impede grain legume cultivation worldwide. Breeding lines with resistance against individual pathogens exist, but these resistances are often overcome by the interaction of multiple pathogens in field situations. Novel tools allow to decipher plant-microbiome interactions in unprecedented detail and provide insights into resistance mechanisms that consider both simultaneous attacks of various pathogens and the interplay with beneficial microbes. Although it has become clear that plant-associated microbes play a key role in plant health, a systematic picture of how and to what extent plants can shape their own detrimental or beneficial microbiome remains to be drawn. There is increasing evidence for the existence of genetic variation in the regulation of plant-microbe interactions that can be exploited by plant breeders. We propose to consider the entire plant holobiont in resistance breeding strategies in order to unravel hidden parts of complex defence mechanisms. This review summarizes (a) the current knowledge of resistance against soil-borne pathogens in grain legumes, (b) evidence for genetic variation for rhizosphere-related traits, (c) the role of root exudation in microbe-mediated disease resistance and elaborates (d) how these traits can be incorporated in resistance breeding programmes.

“…It is unclear if this is the result of selection or evolution for successful strains in this environment or a type of 'soil memory' [74]. Experimental selection for functional rhizospheres has been conducted in the lab with model plant systems [75,76]. Cover crops are being explored as a way to boost populations of desired soil microbes, in addition to other benefits of using these crops in rotation schemes [77].…”
