“…Li et al ( 2021c ) study revealed that after Astragalus mongholicus root infected by F. oxysporum , the plant roots can recruit some beneficial microbes, including Pseudomonas, Strenotrophomonas, Chryseobacterium, Achromobacter , and Flavobacterium . Wu et al ( 2021 ) investigated the differences between Chinese wheat yellow mosaic resistant and susceptible wheat root endosphere and rhizosphere microbial, and the results revealed that beneficial rhizosphere microbes, such as Xanthomonadales, Actinomycetales, Sphingomonas, Rhizobium, Bacillaceae, Bacillus, Streptomycetaceae, Streptomyces, Nocardioides, Pseudonocardia, Bradyrhizobium, Pseudonocardiaceae , and Solibacteraceae , were enriched in the resistant wheat root. Some studies revealed that potential beneficial microbes, such as Bacillus, Paenibacillus, Streptomyces, Pseudomonas, Flavobacterium, Arthrobacter, Rhizobium, Microbacterium, Micrococcous , and Burkholderia , can establish disease suppression by a single strain or SynComs (synthetic microbial communities) via an antagonistic effect to protect the host from pathogens' invasion and attack (Weller et al, 2002 ; Lee et al, 2021 ; Li et al, 2021c ; Marín et al, 2021 ).…”

Anthracnose caused by Colletotrichum spp. was widespread in recent years and resulted in great damage to strawberry production. Soil microbial communities were key contributors to host nutrition, development, and immunity; however, the difference between the microbial communities of healthy and anthracnose-infected strawberry rhizosphere soils remains unclear. In this study, the Illumina sequencing technique was used to comparatively study the prokaryotic and fungal community compositions and structures between healthy and anthracnose-infected strawberry rhizosphere soils in Yuxi, Yunnan Province. Both microbial community diversities and richness of anthracnose-infected strawberry rhizosphere soils were higher than those of healthy strawberry rhizosphere soils. A total of 2,518 prokaryotic and 556 fungal operational taxonomic units (OTUs) were obtained at the 97% similarity threshold. Proteobacteria, Thaumarchaeota, and Acidobacteria were the dominant prokaryotic phyla; Ascomycota, unclassified_k__Fungi, and Mortierellomycota were the dominant fungal phyla. The relative abundances of beneficial bacterial phyla Actinobacteria and Firmicutes, genera Streptomyces, Azospirillum, and Bacillus were significantly reduced in anthracnose-infected strawberry rhizosphere soils; the relative abundance of beneficial fungal species Trichoderma asperellum shows a similar tendency with bacterial abundance. Besides Colletotrichum, 15 other potential fungal pathogen genera and seven fungal pathogen species were identified; among the potential pathogen genera and species, eight pathogen genera and Fusarium oxysporum showed significant differences between healthy and anthracnose-infected strawberry rhizosphere soils. The results suggested that strawberry planted in this area may be infected by other fungal pathogens except for Colletotrichum spp. Our present research will provide theoretical basis and data reference for the isolation and identification of strawberry pathogens and potential probiotics in future works.

“…In contrast, there were more potential pathogens (Fusarium) associated with WYMV-sensitive cultivars than with WYMV-tolerant ones. WYMV-tolerant cultivars had much more complex belowground microbial networks, with larger numbers of mutually beneficial and keystone bacterial taxa, and such microbial association networks may have been responsible for maintaining the stability and ecological balance of the microbial communities (Wu et al 2021b). Data indicates that wheat plants, particularly disease-tolerant cultivars, may be capable of recruiting beneficial microbial microorganism and preventing the collapse of belowground microbial networks after infection with a disease.…”

“…With increasing levels of WYMV infection, the deterministic processes were greatly enhanced during the assembly of bacterial communities, the contribution of deterministic processes to the assembly of bacterial communities increased, and the habitat niche breadth of the bacterial communities decreased. Intensified competition between bacteria and fungi and increased soil totalnitrogen and soil-organic carbon contents under the diseased conditions were primarily responsible for this phenomenon (Zhang et al 2021b). These findings provide an important insight into the associations between the onset of wheat soil-borne virus diseases and alternations in the microbial communities and warrant future research on the application of specific microbial taxa to inhibit wheat soil-borne virus diseases.…”

In China, soil-borne viruses transmitted by the root parasite Polymyxa graminis have caused significant yield loss in winter wheat for many years. At present, it is believed that two main soil-borne RNA viruses, namely wheat yellow mosaic virus (WYMV) and Chinese wheat mosaic virus (CWMV) are responsible for such losses. The molecular characteristics and infection processes of these two viruses have been intensively investigated and described substantially in detail, following the complete sequencing of their respective genomes. In this review, we highlight our recent findings on the distribution of WYMV and CWMV in China, the associated crop damage, the biological functions of WYMV and CWMV proteins as well as the viral temperature sensitivities. We also describe the characteristics of the resistance genes and discuss the novel virus–plant arms race strategies in hope of enlarging our understanding on the theme of virus-plant interactions. Finally, we compare current disease-management options and suggest the application of biotechnology-based genetic resistance to develop more cost-effective countermeasures for controlling soil-borne virus diseases in the future.

“…In the process of plant resistance to pathogen infection, plants themselves also have the recruitment behavior of beneficial microbial communities, which may be active. The enriched microbial communities can enhance soil resistance by interacting with other microbial communities (C. Wu et al, 2021a ; C. Wu et al, 2021b ). Therefore, we believe that microbial diversity plays a positive role in soil quality and soil inhibition (P. Garbeva et al, 2004 ).…”

Rhizosphere-associated microbes have important implications for plant health, but knowledge of the association between the pathological conditions of soil-borne virus-infected wheat and soil microbial communities, especially changes in fungal communities, remains limited. We investigated the succession of fungal communities from bulk soil to wheat rhizosphere soil in both infected and healthy plants using amplicon sequencing methods, and assessed their potential role in plant health. The results showed that the diversity of fungi in wheat rhizosphere and bulk soils significantly differed post wheat yellow mosaic virus disease onset. The structure differences in fungal community at the two wheat health states or two compartment niches were evident, soil physicochemical properties (i.e., NH4+) contribute to differences in fungal community structure and alpha diversity. Comparison analysis showed Mortierellomycetes and Dothideomycetes as dominant communities in healthy wheat soils at class level. The genus Pyronemataceae and Solicoccozyma were significantly are significantly enriched in rhizosphere soil of diseased plant, the genus Cystofilobasidium, Cladosporium, Mortierella, and Stephanonectria are significantly enriched in bulk soil of healthy plant. Co-occurrence network analysis showed that the fungi in healthy wheat soil has higher mutual benefit and connectivity compared with diseased wheat. The results of this study demonstrated that the occurrence of wheat yellow mosaic virus diseases altered both fungal community diversity and composition, and that NH4+ is the most important soil physicochemical factor influencing fungal diversity and community composition.
