“…The relative increase in the content of growth-promoting substances was related to the enhancement of the plant’s disease resistance to Rhizoctonia solanacearum . IAA plays a role in the defense process of plants against pathogenic infection [ 94 ]. Ortu et al [ 95 ] found that GA synthesis genes were upregulated in Medicago truncatula after AMF infection.…”

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.

“…Fungi inoculation could promote the growth of their host plants by several mechanisms such as increasing hormones and absorption of useful nutrients for plants ( Guo and Wang, 2001 , Sherameti et al, 2005 , Chen et al, 2011 , Waqas et al, 2015 , Jia et al, 2016 , Metwally and Al-Amri, 2020 ). The inoculation with endophytic fungi as Penicillium citrinum and Aspergillus terreus promoted plant biomass and other growth characteristics such as stem diameter, shoot fresh/dry weight, shoot length, and photosynthetic function by increasing the levels of endogenous Jasmonic acid and Salicylic acid of the host plant ( Waqas et al, 2015 ).…”

“…At the molecular level, endophytic fungus Piriformospora indica promotes the growth of Arabidopsis and tobacco roots by stimulating gene expression for nitrate reductase and the starch degrading enzyme (glucan-water dikinase) ( Sherameti et al, 2005 ). The inoculation of onion ( Allium cepa ) plants by AM fungi in combination with biocontrol fungus ( Trichoderma viride ) significantly increased onion growth parameters (fresh and dry weights, root and shoot lengths and leaf area) and also improved chlorophyll, carotenoids, and total pigments in onion leaves ( Metwally and Al-Amri, 2020 ).…”

“…Although pathogen progression in root tissue is hindered by the new Trichoderma strain, the presence of the fungus does not interfere with AMF colonization. Recently, Metwally and Al-Amri (2020) showed an interactive role of Trichoderma viride and AMF on growth and pigment content of onion plants, however, due to the small number of AMF−Trichoderma-host plant combinations that have been investigated so far, general conclusions on those tripartite interactions are not possible (cf. Szczałba et al, 2019).…”

Plants host numerous endophytic microbes which promote plant performance, in particular under stress. A new endophytic fungus was isolated from the leaves of a deciduous wood tree Leucas aspera. Morphological inspection and multilocus phylogeny identified the fungus as a new Trichoderma strain. If applied to Arabidopsis thaliana and Nicotiana attenuata, it mainly colonizes their roots and strongly promotes initial growth of the plants on soil. The fungus grows on high NaCl or mannitol concentrations, and shows predatory capability on the pathogenic fungus Alternaria brassicicola. Colonized Arabidopsis plants tolerate higher salt stress and show lower A. brassicicola spread in roots and shoots, while arbuscular mycorrhiza formation in N. attenuata is not affected by the Trichoderma strain. These beneficial features of the novel Trichoderma strain are important prerequisites for agricultural applications.
