“…Note: Averages followed by the same letter do not differ by Tukey's test, at a 5% probability level (A1).Cell membrane damages are commonly observed in plants exposed to abiotic stresses, especially saline stress(Hashem et al, 2019). There are numerous studies that prove the deleterious effects of salinity on the stability of plasma membranes, which is relieved by mycorrhizae colonization(Navarro et al, 2014;Amanifar et al, 2019) depending on the AMF species used, corroborating the results observed in the present study.The increased concentration of reactive oxygen species (ROS) in the cellular protoplasm causes lipid peroxidation of membranes, which is favored by salinity(Hashem et al, 2018). However, this damage is relieved by the synthesis of antioxidant compounds, such as proline and glycine-betaine, as well as increased activity of superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX), since their synthesis and activities are intensified in mycorrhized plants.…”

“…studied citrus seedlings (Poncitrus trifoliata) with and without mycorrhizae for a period of 61 days, which were submitted to saline conditions (0 and 100 mM Of NaCl -) for 45 days. They observed an increase in the Na + concentration in leaf tissue as a function of salinity independent from mycorrhizal inoculation, but the use of mycorrhizae decreased the concentration of this ion by up to 31% under saline stress condition (100 mM of NaCl -) when compared to no mycorrhizae Amanifar et al (2019). observed similar results when studying the effect of irrigation with increasing salt levels in Glycyrrhiza glabra plants with and without mycorrhizae.…”

The objective of the present study was to evaluate the effect of mycorrhization on the nutritional, hydric and biochemical components of papaya seedlings, Carica papaia L., from the Formosa Group, Hybrid Tainung Nº 1, submitted to irrigation with saline water. The research was conducted at the Federal Institute of Paraíba, Sousa Campus, from March to December 2018. The experimental design used completely randomized blocks, with treatments arranged in a 4 x 5 factorial scheme, referring to the fungi species: Gigaspora candida, Acaulospora scrobiculata, Dentiscutata heterogama and without mycorrhizae, and the five salt concentrations in irrigation water: 0.0; 10.0; 20.0; 30.0 and 40.0 mmolc L-1 in four repetitions. The characteristics evaluated were: relative water content, water saturation deficit, membrane damage, photosynthetic pigments, concentration and accumulation of nitrogen, phosphorus, potassium, sodium and the relationship between potassium and sodium concentrations in leaf tissue. The species D. heterogama and G. candida presented the highest rates of leaf hydration and the lowest damage to biomembranes at all saline levels. Mycorrhizae increased the absorption of N and P, especially from 30 mmolc L-1 of salt. A greater relationship between potassium and sodium concentrations was evidenced in seedlings mycorrhized with D. heterogama.

“…Other authors [68] reported the effect of Glomus intraradices inoculation in enhancing the phenolic profile of rosemary leaves. Amanifar et al [69] recorded the increased antioxidant synthesis promoted by Funneliforms mosseae in liquorice under salt conditions, compared to non-inoculated control. Unlike the results of the present research, Nzanza et al [70] did not detect overall benefits for antioxidant compounds or the activity of tomato fruits upon inoculation with Trichoderma harzianum and Glomus mosseae.…”

With the aim of assessing the effects of beneficial microorganisms on greenhouse tomato “plum” grown under salinity conditions, research was carried out in southern Italy from summer to winter, by comparing two arbuscular mycorrhizal fungi (AMF) based formulates (Rizotech Plus, Myco Apply DR) and a non-inoculated control, in factorial combination with four soil electrical conductivities (1.5, 3.0, 4.5, 6.0 mS·cm−1 EC). The highest root colonization was 83% at 3.0 mS·cm−1 under AMF-based treatments and 34% at 1.5 mS·cm−1 in non-treated control; the latter attained lower values than AMF treatments at any soil EC. Harvest occurred 3.5 days earlier in control plants, six days earlier under 6.0 mS·cm−1 EC compared to 1.5 mS·cm−1. The inoculated plants always showed higher yield than the control ones and the highest production at 4.5 mS·cm−1 EC; control plants attained the highest yield under 3.0–4.5 mS·cm−1 EC. The highest values of most fruit quality indicators, mineral elements and antioxidant compounds and activity were recorded under AMF-based formulates inoculation and 6.0 mS·cm−1 soil EC. Beneficial microorganisms proved to be an effective environmentally friendly tool for improving tomato yield and quality performances in both normal and soil salinity conditions.

“…Moreover, the SEM analysis showed that root biomass had direct negative effects on the Na + content in the roots. DSE promoted the growth of plant roots and caused a dilution effect, which may be an important reason for the decrease in Na + in the roots [59]. In addition, G − bacteria had direct negative effects on the Na + content in roots.…”

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.
