Summary: The fungus Fusarium oxysporum f. sp. lycopersici (FOL) causes vascular wilt in tomatoes globally, but a consortium of arbuscular mycorrhizal fungi (AMF) can reduce wilt disease, enhance plant resistance, and inhibit fusaric acid production. Additionally, AMF can increase chlorophyll content and phosphate-metabolizing enzyme activity, while also boosting antioxidant enzyme levels and photosynthetic performance to induce resistance against FOL in tomatoes.

Summary: The contrasting life-history characteristics of different arbuscular mycorrhizal fungal families have significant implications for tomato fruit quality parameters. Inoculation with AM fungi from Glomeraceae and Gigasporaceae increased the total phenols and lycopene concentration in tomato fruits, and enhanced the antioxidant activity. Gigaspora gigantea outperformed Scutellospora pellucida in terms of fruit quality parameters.

Summary: The study found that fungal communities in grapevine soil were more responsive to treatments, while changes in bacterial communities were mainly observed between different treatments. Soil factors had minimal influence on microbial communities. Microbial network analysis revealed that bacterial associations were weaker under half irrigation, and that inoculation with AMF increased positive associations between vineyard soil-living microbes.

Summary: This study explored the modulating effect of arbuscular mycorrhizal fungi symbiosis on water deficit stress symptoms in two medicinal and aromatic plants. The results showed that mycorrhizal fungi inoculation alleviated the deleterious impacts of water stress and significantly influenced the composition and content of essential oils. These effects may be attributed to improved phosphorus uptake, chlorophyll biosynthesis, relative water content, and antioxidant activities. The findings highlight the importance of symbiosis with mycorrhizal fungi in increasing tolerance to water deficit stress in medicinal and aromatic plants.

Summary: The study found that 6 weeks of resistance training reduced oxidative damage and increased antioxidant enzyme activities in skeletal muscle of older adults. The responses of older adults to resistance training involve multi-level control (transcriptional, post-transcriptional, and post-translational) of the redox status of skeletal muscle.

Summary: Through analyzing 74,563 forest inventory plots across 35 ecoregions in the contiguous USA, it was found that mixed mycorrhizal plots were more productive than plots dominated by either arbuscular or ectomycorrhizal fungal-associated tree species in approximately 77% of the ecoregions. The positive effects of mixing mycorrhizal strategies on forest productivity were more pronounced at low tree species richness. These findings highlight the importance of mixed mycorrhizal strategies, as well as overall taxonomic diversity, for maintaining ecosystem functioning in forests.

Summary: Symbiosis with arbuscular mycorrhizal fungi increases bacterial diversity and promotes deterministic processes of bacterial community construction in the rhizosphere. AM fungi enrich specific bacteria positively correlated with NPK-related parameters and capable of nutrient mineralization and dissolution. This study reveals that AM fungi regulate rhizosphere bacterial community assembly and attract specific rhizosphere bacteria to promote soil nutrient turnover in southern grasslands.

Summary: This study isolated bacterial strains from rhizospheric and bulk soil to evaluate their potential for bioremediation, specifically in phytorhizoremediation of heavy metal polluted soil, particularly mercury. They proposed the Bio-Mercury Remediation Suitability Index (BMR-SI) to select strains with potential biotechnological use, which must rigorously fulfill established criteria for further assays.

Summary: This study conducted comparative analysis of microbial communities in rhizospheric soils and bulk soil of the mining region of Almaden in order to understand the effects of mercury contamination. The results showed that the rhizospheric soil had a higher abundance of Proteobacteria compared to the bulk soil, indicating a selective effect of roots on the rhizospheric communities. Additionally, it was found that environments contaminated by mercury exhibited co-selection of resistance mechanisms to mercury and antibiotics or other toxic compounds. The study also identified sequences involved in nitrogen fixation and plant growth promotion, which could be useful in bioremediation processes in mercury-contaminated environments.

Summary: The misuse of chemical fertilizers in intensive agriculture has resulted in pollution of the soil and groundwater, while the management of agricultural waste poses a threat to the environment and human health. To address the growing demand for sustainable alternatives, using microbiological treatments to convert agricultural waste into natural biofertilizers is presented as a viable solution. Experimental results show that the addition of Plant Growth Promoting Bacteria (PGPB) in the biofertilizer significantly improves plant germination, viability, and biomass.

Summary: Mercury pollution is a serious problem for the environment and health, and it can lead to antibiotic resistance in bacteria. Using bacteria that promote plant development can help plants adapt to polluted environments, decontaminate sites, and prevent the spread of antibiotic resistance. This study proposes a method to evaluate the beneficial impact of bacteria in mitigating antibiotic resistance in mercury-contaminated soils.

Summary: Mercury, a highly toxic heavy metal, poses a threat to human and environmental health due to its pollution on soils and its ability to spread through atmosphere and aquatic environments. Bioremediation using microorganisms and/or plants is considered as a sustainable alternative to traditional physicochemical methods for reducing mercury in ecosystems. Different strategies, such as volatilization, biosorption, phytoextraction, and phytoremediation, take advantage of the natural and evolutionary capacity of organisms to adapt to pollutants. The use of these bioremediation methodologies has been successfully applied in various ecosystems and is seen as a respectful alternative for the recovery of degraded environments.
