Summary: This study explores the potential of plant biotization, specifically the use of root-inhabiting fungi, to promote the growth of Vaccinium corymbosum. The researchers found that the fungal strains Oidiodendron maius and Phialocephala fortinii were the most beneficial for plant growth in single inoculation experiments. Further experiments using a combination of root symbiotic fungi and endophytic fungi showed increased plant height and biomass, indicating the potential of these methods for large-scale blueberry production.

Summary: The symbiotic relationship between plants and arbuscular mycorrhizal fungi (AMF) is now known to be influenced by mycorrhizal helper bacteria (MHB), which play a crucial role in promoting the development and functioning of AMF by influencing spore germination, mycelial growth, root colonization, metabolic diversity, and biocontrol of soil borne diseases; MHB also enhance the efficiency of arbuscular mycorrhizal symbiosis by triggering plant growth factors, leading to better nutrient uptake by plants.

Summary: This study manipulated AMF communities in grapevine rootstock and found that specific AMF communities had differential effects on grapevine rootstock growth and nutrient uptake. The presence of its own AMF community generally improved the performance of a rootstock. AMF spore diversity and the relative abundance of certain species played important roles in competition and growth outcomes.

Summary: Mycorrhiza is a symbiotic association between plant roots and fungi, with arbuscular mycorrhizal fungi (AMF) being the most prominent type. AMF rely on host plants for photosynthates and provide benefits in return. They help improve host plants' tolerance against various biotic stresses through mechanisms like nutrient competition and rhizosphere alteration. The effectiveness of AM associations in conferring biotic stress tolerance is influenced by various biotic and abiotic factors.

Summary: The dual inoculation of maize with AMF and DSE from other plant species had positive effects on plant growth, with the outcome depending on the density of DSE. Low density DSE had lesser impact on plant growth compared to medium or high densities, and AMF promoted above-ground growth more than DSE, while high density DSE promoted root development more than AMF. The combination of AMF and DSE could lead to synergistic growth effects at low DSE density and competitive effects at medium to high DSE densities.

Summary: The study found that the fungal microbiome associated with Festuca rubra subsp. pruinosa in sea cliffs has a significant impact on plant growth performance under conditions of salinity and nutrient availability. The fungi P. macrospinosa promoted leaf and root growth in the presence of salinity, while F. oxysporum decreased leaf Na+ content under salinity. These fungi provide important complementary functions for plant adaptation to their habitat.

Summary: This study found that the roots of Ulex europaeus plantlets in native ecosystems in south-central Chile host a diverse array of endophytic fungi and bacteria, some of which have plant growth-promoting traits and biocontrol potential. These beneficial interactions contribute to the rapid growth rates of U. europaeus at the juvenile stage and explain its ability to colonize various ecosystems.

Summary: The article discusses the endangered status of orchids in the plant kingdom and proposes a new reintroduction method for orchids by co-sowing orchid seeds directly with orchid mycorrhizal fungi carrying ecological specificity. This innovative approach aims to reconstruct long-term and self-sustained orchid populations, representing a potential benefit for the reintroduction of endangered orchids in nature.

Summary: This study investigated the metabolic differences in the symbiotic relationship between different AMF (arbuscular mycorrhizal fungi) species and crop plants. The results showed that Rhizophagus irregularis formed a mutualistic symbiosis with plants, promoting phosphorus uptake and plant growth; while Gigaspora gigantea exhibited a parasitic relationship, inhibiting plant growth and producing antifungal compounds. Furthermore, when multiple AMF species were present, mutualistic symbiosis dominated.

Summary: This study aimed to identify the AMF taxa colonizing grapevines in New Zealand vineyards and investigate the effect of grapevine rootstocks on AMF community diversity and composition. The results demonstrated that rootstock significantly influenced the AMF community composition in all sites, highlighting the importance of rootstock cultivar in shaping the arbuscular mycorrhizal community colonizing the roots.

Summary: Analysing the diversification dynamics of the subphylum Glomeromycotina, the microscopic arbuscular mycorrhizal fungi that have been symbiotically associated with land plants for millions of years, this study reveals that they have low speciation rates compared to other eukaryotes. After a peak of speciation between 200 and 100 million years ago, a decline in speciation rates is observed, possibly due to a shrinking mycorrhizal niche and limited ability to colonize new niches.

Summary: Durum wheat is an important agricultural crop, but its productivity is threatened by drought stress. The study found that the response of different durum wheat genotypes to drought stress varied and that arbuscular mycorrhizal fungi played a positive role in sulfur homeostasis. These results suggest that nutrient use efficiency and soil components should be considered in the identification of drought tolerant plants.

Summary: The study investigated the symbiosis between Arbuscular mycorrhizal fungi (AMF) and Canna indica for nitrogen (N) absorption in contaminated soil. Results showed that AMF significantly improved the absorption of NH4+-N by Canna plants, while having no significant impact on NO3--N absorption. Additionally, when NH4+-N and NO3--N were applied together, their respective absorption rates were significantly enhanced.

Summary: The AM-inducible SWEET transporter GmSWEET6 plays a crucial role in arbuscular mycorrhizal symbiosis by mediating the efflux of sucrose towards the fungi. Overexpression of GmSWEET6 increases root P content and decreases the percentage of degraded arbuscules, while knockdown of GmSWEET6 results in increased root sugar concentrations and the percentage of degraded arbuscules.
