“…Since AMF live in the soil and infect the roots of plants, they have the most significant effect on soil-borne diseases [ 17 , 18 ]. AMF has been widely used as a biological control method to control various phytopathogenic fungi [ 19 ]. For example, Schönbeck and Dehne [ 20 ] found that mycorrhizal cotton plants were more resistant to infection with the pathogen Thielaviopsis basicola than those with sterile roots.…”

Arbuscularmycorrhizal fungi (AMF) are a class of beneficial microorganisms that are widely distributed in soil ecosystems and can form symbionts with 80% of terrestrial higher plants, and improve the nutritional status of plants. The use of AMF as a biocontrol method to antagonize soil-borne pathogens has received increasing interest from phytopathologists and ecologists. In this paper, the mechanisms of resistance to diseases induced by AMF and the application of AMF to plant fungal, bacterial, and nematode diseases have been summarized. This study aimed to enhance the potential use of AMF as a biological control method to prevent plant diseases in the future. Root morphological alteration characteristics were explained, including the influence of AMF on root structure, function, and the regulation of AMF via secondary metabolites. AMF can improve the rhizosphere environment by influencing the physical and chemical proprieties of soil, enhancing the growth of other beneficial microorganisms, and by competing with pathogenic microorganisms. Two microorganism types may compete for the same invasive sites in root systems and regulate nutrition distribution. AMF can induce the host plant to form defense systems, including improving phytohormone concentrations, inducing signal substrate production, gene expression regulation, and enhancing protein production.

“…Finally, pathogen invasion and reproduction were stopped, while plant resistance was enhanced [ 49 , 50 ]. Lin et al (2021) found that the defense system of host plant could be activated by biological control agents and the ability to resist pathogen invasion was improved [ 51 ]. The present study showed that the antioxidant enzyme activity of banana roots could be improved after banana infection with Foc Tr4.…”

The purpose of this study was to determine the effect and mechanism of alkaline fertilizer, bio-control fungi, and their synergistic application on control of Fusarium Tr4 incidence. Synchronized use of the alkaline fertilizer and biocontrol fungi eliminates rhizome browning and reduces the incidence rate of banana Fusarium wilt. The incidence of yellow leaves (ratio of yellow leaf to total leaf) and disease index in +Foc Tr4 CF treatment were the same (65%), while incidence of yellow leaves and disease index in +Foc Tr4 AFBCF were 31% and 33%, respectively. Under the stress of Foc Tr4 infection, the synergistic utilization of the alkaline fertilizer and biocontrol fungi would raise the activities of peroxidase, catalase and superoxide dismutase in banana roots. The root activity of banana was also increased. As a result, the banana height and stem diameter increments, shoot and root dry weight, accumulation of N, P and K in banana plants had been increased. The efficacy of the synergistic application of alkaline fertilizer and biocontrol fungi was not only reducing Foc Tr4 pathogen colonization and distribution in banana plants, but also preventing tylosis formation in vascular vessel effectively. Therefore, the normal transport of water and nutrients between underground and aboveground is ensured.

“…Host plants provide AMF with carbon (photosynthates and fatty acids), while in return, fungi supply plants with essential mineral nutrients, principally phosphorus (P) and nitrogen (N) ( Parniske, 2008 ; Püschel et al., 2020 ; Zai et al., 2021 ; Ma et al., 2022 ; Ho-Plágaro and García-Garrido, 2022a ). Moreover, AM symbiosis improves plant growth, production, and tolerance to various biotic and abiotic stresses ( Sabra et al., 2018 ; Gao et al., 2020 ; Zhang et al., 2020 ; Jajoo, 2021 ; Lin et al., 2021 ; Jumrani et al., 2022 ). Accordingly, AMF have become symbionts of several research interests and are recommended for wide use as bio-fertilizers to enhance crops’ quality and productivity under the ever-changing climate and to ensure sustainable agriculture ( Igiehon and Babalola, 2017 ; Begum et al., 2019 ).…”

IntroductionPlants and arbuscular mycorrhizal fungi (AMF) mutualistic interactions are essential for sustainable agriculture production. Although it is shown that AMF inoculation improves cassava physiological performances and yield traits, the molecular mechanisms involved in AM symbiosis remain largely unknown. Herein, we integrated metabolomics and transcriptomics analyses of symbiotic (Ri) and asymbiotic (CK) cassava roots and explored AM-induced biochemical and transcriptional changes.ResultsThree weeks (3w) after AMF inoculations, proliferating fungal hyphae were observable, and plant height and root length were significantly increased. In total, we identified 1,016 metabolites, of which 25 were differentially accumulated (DAMs) at 3w. The most highly induced metabolites were 5-aminolevulinic acid, L-glutamic acid, and lysoPC 18:2. Transcriptome analysis identified 693 and 6,481 differentially expressed genes (DEGs) in the comparison between CK (3w) against Ri at 3w and 6w, respectively. Functional enrichment analyses of DAMs and DEGs unveiled transport, amino acids and sugar metabolisms, biosynthesis of secondary metabolites, plant hormone signal transduction, phenylpropanoid biosynthesis, and plant-pathogen interactions as the most differentially regulated pathways. Potential candidate genes, including nitrogen and phosphate transporters, transcription factors, phytohormone, sugar metabolism-related, and SYM (symbiosis) signaling pathway-related, were identified for future functional studies.DiscussionOur results provide molecular insights into AM symbiosis and valuable resources for improving cassava production.
