“…Utilizing beneficial endophytic fungi such as arbuscular mycorrhizal (AM) fungi, dark septate endophytes (DSE) and Trichoderma spp. is one of the most promising strategies for improving plant growth and stress tolerance through modulating morphogenesis and physiological processes of their associated plants, thereby enhancing the ability of plants to cope with environmental stresses (Mona et al ., 2017 ; He et al ., 2019 ; Xu et al ., 2020 ). Numerous studies have reported the roles of endophytic fungi in plant development under both normal conditions as well as in the presence of various abiotic stresses, such as drought, salinity and heavy metal exposure (Wani et al ., 2015 ; Li et al ., 2019a ; Hou et al ., 2020 ).…”

Rhizosphere microbiome adapts their structural compositions to water scarcity and have the potential to mitigate drought stress of plants. To unlock this potential, it is crucial to understand community responses to drought in the interplay between soil properties, water management and exogenous microbes interference. Inoculation with dark septate endophytes (DSE) (Acrocalymma vagum, Paraboeremia putaminum) and Trichoderma viride on Astragalus mongholicus grown in the non-sterile soil was exposed to drought. Rhizosphere microbiome were assessed by Illumina MiSeq sequencing of the 16S and ITS2 rRNA genes. Inoculation positively affected plant growth depending on DSE species and water regime. Ascomycota, Proteobacteria, Actinobacteria, Chloroflexi and Firmicutes were the dominant phyla. The effects of dual inoculation on bacterial community were greater than those on fungal community, and combination of P. putaminum and T. viride exerted a stronger impact on the microbiome under drought stress. The observed changes in soil factors caused by inoculation could be explained by the variations in microbiome composition. Rhizosphere microbiome mediated by inoculation exhibited distinct preferences for various growth parameters. These findings suggest that dual inoculation of DSE and T. viride enriched beneficial microbiota, altered soil nutrient status and might contribute to enhance the cultivation of medicinal plants in dryland agriculture.

“…We then selected these two fungi for further study on their plant growth promoting effects on sunchoke under field conditions. Several studies have reported the co-inoculation of EPF and AMF to promote plant growth, for example, Xu et al [18] found that synergistic interaction between EPF and AMF could simultaneously promote plant growth and enhance drought resistance in peanut plants. Moreover, Wezowicz et al [10] reported that the co-inoculation of AMF and EPF could help the Verbascum lychnitis seedlings to survive and improve various plant growth parameters, especially the biomass and yield of the plants.…”

Endophytic fungi (EPF) and arbuscular mycorrhizal fungi (AMF) symbioses can promote the growth and productivity of several types of plants. This work aimed to investigate the effect of co-inoculation of an EPF Exserohilum rostratum NMS1.5 and an AMF Glomus etunicatum UDCN52867 g.5 on the growth and yields of sunchoke (Helianthus tuberosus L.) compared to the effects of full-dose and half-dose chemical fertilizer (15–15–15) under field conditions. Several plant growth parameters of the co-inoculated plants were significantly higher than the other treatments. Remarkably, such an effect was relatively equal to that of the full-dose chemical fertilizers. Moreover, the co-inoculation of EPF and AMF significantly improved the tuber yield production, even better than the use of a chemical fertilizer. This is the first report to show that plant growth promoting effects of the co-inoculation of EPF and AMF were exceptionally greater than those of the chemical fertilizer. Therefore, our EPF and AMF could potentially be used as a biofertilizer for promoting the growth and yield of sunchoke in the fields.

“…Then, 3 cm of surface soil was removed from the pots. After removing large soil particles from the root system, the firmly attached soil (1–2 mm from the root tissue) was collected with a total of 10 g, which was regarded as the rhizosphere soil [ 33 ] Then, samples were wet sieved and the decantation-sucrose centrifugation method was used to separate soil AMF fungal spores [ 34 ]. The number of spores was recorded under a light microscope (CX43, Olympus, Tokyo, Japan).…”

Drought stress is one of the greatest obstacles affecting field crop productivity in arid and semi-arid regions, and its severity and frequency are expected to increase due to human-induced changes to the environment and climate. Drought has led to rocky desertification in Karst regions. Cinnamomum migao is a unique, fast-growing medicinal plant of Southwest China that only thrives in Karst regions. Arbuscular mycorrhizal fungi (AMF) symbiosis alleviates drought stress in plants; however, establishment and function of the symbiotic interaction between AMF host plant in relation to the inoculation method remain unclear. Therefore, we conducted an experiment to investigate the effects of AMF species (Glomus etunicatum and Funneliformis mosseae) and two inoculation methods (seed vs. seedling inoculation) under drought stress on C. migao seedlings, and quantified mycorrhizal colonization, AMF spore density, root vigor, relative water content, C. migao growth, antioxidant enzyme activities, and osmotic adjustment. Inoculation with AMF (G. etunicatum and F. mosseae) positively affected the growth and root vigor of Cinnamomum migao under drought stress, regardless of the inoculation method. Additionally, both AMF species markedly upregulated antioxidant enzyme activities and osmotic adjustment substances, regardless of the inoculation method. Our results showed that the collective stimulatory effect of G. etunicatum is more efficient than that of F. mosseae. AMF application could promote afforestation with C. migao to prevent rocky desertification in Karst regions where water is the greatest limiting factor on plant growth and yield.
