“…However, the use of similar methods to prevent chestnut blight in the Americas has never achieved the same effect (Liu et al, 2015;Andika et al, 2017;Abdoulaye et al, 2019). This is because the vegetative incompatibility groups of American chestnut blight are more complicated than those in Europe, which hinders the control effect (Wei et al, 2019;Dejasikora et al, 2020). Some phytopathogenic fungi that carry a certain type of virus can exhibit low pathogenicity (virulence decay) characteristics that are mediated by the virus, thereby protecting the host plant (Ding et al, 2019;Thapa and Roossinck, 2019).…”

“…During the infection process of pathogenic fungi, natural factors such as wind, rain, and the frequency of contact between insects and fungi are important factors that affect the pathogenesis of the host. Carneiro et al (2008) found that four out of 24 B. bassiana strains isolated from Brazil could kill 100% of 2-year-old S. frugiperda larvae; the mortality rate of S. frugiperda was as high as 100% on the seventh day after inoculation of the third instar larvae of S.

Phytopathogenic fungi decrease crop yield and quality and cause huge losses in agricultural production. To prevent the occurrence of crop diseases and insect pests, farmers have to use many synthetic chemical pesticides. The extensive use of these pesticides has resulted in a series of environmental and ecological problems, such as the increase in resistant weed populations, soil compaction, and water pollution, which seriously affect the sustainable development of agriculture. This review discusses the main advances in research on plant-pathogenic fungi in terms of their pathogenic factors such as cell wall-degrading enzymes, toxins, growth regulators, effector proteins, and fungal viruses, as well as their application as biocontrol agents for plant pests, diseases, and weeds. Finally, further studies on plant-pathogenic fungal resources with better biocontrol effects can help find new beneficial microbial resources that can control diseases.

“…Similar observations were made by Larkin (2008) when a mix of AM fungi resulted in reduced stem canker and black scurf in the potato crop. AM fungi also act by alleviating H 2 O 2 in PVY stressed potato plants (Deja-Sikora et al, 2020). They can upregulate defense mechanisms upon herbivore attack against disease vectors such as aphids (Rizzo et al, 2020), as in the case with PVY.…”

The potato (Solanum tuberosum L.) is an important tuber crop with high dietary value that could potentially help to alleviate malnutrition and hunger in Africa. However, production is expensive, with high fertilizer and pesticide demands that lead to environmental pollution, and tillage practices that negatively affect soil structure. Microorganisms of different types have increasingly been found to be useful as biofertilizers, and arbuscular mycorrhizal (AM) fungi are an important crop symbiont. AM fungi have been shown to increase tolerance of crop plants to drought, salinity and disease by facilitating water and nutrient acquisition and by improving overall soil structure. However, the establishment and maintenance of the symbioses are greatly affected by agricultural practices. Here, we review the benefits that AM fungi confer in potato production, discuss the role and importance of mycorrhiza helper bacteria, and focus on how AM fungal diversity and abundance can be affected by conventional agricultural practices, such as those used in potato production. We suggest approaches for maintaining AM fungal abundance in potato production by highlighting the potential of conservation tillage practices augmented with cover crops and crop rotations. An approach that balances weed control, nutrient provision, and AM fungal helper bacterial populations, whilst promoting functional AM fungal populations for varying potato genotypes, will stimulate efficient mycorrhizal interventions.

“…Previous studies have shown that plant tolerance to stress, such as drought, salinity and high temperature, is closely related to the colonization of endophytic fungi [15,16]. Hence, the resource excavation of these associated endophytic fungi containing dark septate endophytes (DSE) is vital for improving the health and productivity of plants, especially for plant growth and vegetation restoration in degraded soils [17,18]. DSE represent a diverse group of endophytic fungi mainly involving ascomycetes, which propagate via conidia or asexual reproduction.…”

Background: Fungal endophytes can improve plant tolerance to abiotic stress, however, the role of these plant–fungal interactions in desert species ecology and their management implications remain unclear. This study aimed to assess whether dark septate endophytes (DSE) can shift the performance of Artemisia ordosica and associated soil microbial community under salt stress.Methods: We investigated the effects of three DSE (Alternaria chlamydosporigena [AC], Paraphoma chrysanthemicola [PC] and Bipolaris sorokiniana [BS]) isolated from desert habitats on plant morphology, physiology and rhizosphere soil microhabitat of Artemisia ordosica seedlings under different NaCl concentrations (0 %, 0.1 %, 0.2 %, and 0.3 %) in a growth chamber. Results: Three DSE strains could colonize the roots of A. ordosica, and the symbiotic response with host plants depended on DSE species and NaCl concentration. The greatest benefits associated with DSE occurred under 0.1 % NaCl. Specifically, AC improved root morphology, and increased total biomass and superoxide dismutase (SOD) activity; PC increased root morphology, root biomass, and glutathione (GSH) and indoleacetic acid (IAA) contents; and BS promoted SOD activity and GSH and IAA contents. DSE reduced the root Na+ content. Interestingly, BS promoted gram-positive (G +) and gram-negative (G −) bacteria under 0.1 % NaCl and the abundance of AM fungi under 0.2 % and 0.3 % NaCl. PC positively affected fungi, AM fungi, G − bacteria and actinomycetes under 0.2 % and 0.3 % NaCl, while AC increased the abundance of all examined microbes under 0.3 % NaCl. A structural equation modeling (SEM) demonstrated that DSE not only positively affects A. ordosica performance but also directly or indirectly impacts soil microbes by regulating the soil organic carbon (SOC), available phosphorus (AP), and alkaline nitrogen (AN) content.Conclusions: DSE isolated from A. ordosica enhanced the root development of host plants and altered the soil nutrient content and soil microbiota under different NaCl concentrations, possibly contributing to plant growth and ecological adaptability under saline environment. These results contribute to the understanding of the ecological function of DSE in desert ecosystems and may be used to promote vegetation restoration in salinized desert areas.
