Summary: Nickel is a fundamental micronutrient in plants, but can inhibit plant growth and metabolism at high levels by inducing oxidative stress. Polyamines (PAs) and arbuscular mycorrhiza (AM) have been found to help plants withstand nickel toxicity, with AM showing the most effectiveness followed by Put and Spd, while Spm has the least impact. The use of combined applications of PAs (especially Put) and R. intraradices is recommended as an effective strategy for mitigating nickel toxicity in pigeonpea genotypes, particularly with Pusa 2001 being more responsive to PAs priming.

Summary: Mycorrhizal symbioses have a significant impact on plant performance and ecosystem dynamics. Plant mycorrhizal traits offer valuable insights into belowground functionality. This study explores the correlation between phylogenetics, environmental factors, and plant mycorrhizal traits using a plant phylogenetic mega-tree and high-resolution climatic and edaphic data layers. The findings suggest that plant mycorrhizal type is more phylogenetically conserved, while environmental variables play a larger role in determining mycorrhizal status.

Summary: This study evaluated the effect of mycorrhizal arbuscular fungi (AMF) combined with plant-growth-promoting rhizobacteria (PGPR) on the growth and nutritional status of apple trees under organic farming conditions. The results showed that the inoculation of AMF + PGPR resulted in a higher root mycorrhizal frequency, increased trunk cross-section area, and changes in nutrient concentrations in the leaves. The use of AMF + PGPR inoculum supported better tree roots colonization, leading to improved nitrogen and magnesium uptake, but also caused a decrease in phosphorus and potassium content, potentially due to competition for nutrients in the soil.

Summary: The association between plants and arbuscular mycorrhizal fungi (AMF) can enhance their resistance to herbivorous insects, as shown by a study on tomato plants colonized by Funneliformis mosseae. Metabolomic analysis revealed that this symbiosis had a limited impact on leaf metabolism under normal conditions, but significantly modulated the response to herbivory in damaged areas. Primed accumulation of defensive compounds such as alkaloids, fatty acid derivatives, and phenylpropanoid-polyamine conjugates was observed in damaged leaflets of mycorrhizal plants, showcasing the impact of AMF on metabolic reprogramming in response to herbivory.

Summary: This article summarizes recent data on nutrient transfer in orchid and arbuscular mycorrhiza, and compares the development and function of fungal structures formed in these symbioses, outlining differences and similarities. Unexpected similarities in intracellular mycorrhizal fungal structures observed in orchids and mycoheterotrophic plants forming arbuscular mycorrhiza are described. The article speculates that these similarities may be a result of convergent evolution of mycorrhizal types in mycoheterotrophic plants and highlights knowledge gaps and new research directions.

Summary: This study investigated the interactions between arbuscular mycorrhizal fungi (AMF), foliar endophytes, and insects on Impatiens glandulifera. The results showed that AMF reduced plant biomass, while foliar endophytes increased aphid numbers. There were more interactions between AMF and endophytes than between endophytes themselves.

Summary: This study found that arbuscular mycorrhizal fungi (AMF) were present in the roots of selected plants in the University of Rajshahi campus in Bangladesh, with different colonization rates in different plant families. The deficient nutrient levels in the rhizospheric soils may promote mycorrhizal symbiosis with plants.

Summary: This study assessed the efficacy of four arbuscular mycorrhizal fungi (AMF) species in imparting cadmium stress tolerance to pigeonpea plants. The results showed that mycorrhizal supplementations enhanced growth and yield by reducing cadmium uptake and improving carbohydrate synthesis of stressed plants. Rhizoglomus intraradices showed the highest efficacy in alleviating cadmium stress.

Summary: The study identified the crucial role of legume TOR in the development of AM fungal symbiosis, showing that suppressing TOR transcripts significantly affects lateral root formation and the quantity of internal and external fungi in the roots. It also indicated that PvTOR primarily influences root development during AM symbiosis by regulating arbuscule formation.

Summary: The research reveals that Lotus burttii has a higher promiscuity in interactions with rhizobia compared to Lotus japonicus, allowing it to form nodules with rhizobia from five different genera. The mapping of the Gifu/burttii promiscuity quantitative trait locus (QTL) to the same genetic locus regardless of the rhizobial genus suggests a common genetic mechanism for symbiont-range expansion.

Summary: The establishment of root-nodule symbiosis in legumes can occur through either root hair infection threads or intercellular passage of bacteria. Research has shown that the intercellular infection mechanism is still poorly understood, but recent discoveries have shed some light on this process.

Summary: This study demonstrates the crucial role of the regulation of aromatic amino acid biosynthesis in sustaining root hair growth and establishing symbiotic relationships in the legume Lotus japonicus. The enzyme DAHPS1 is found to be critical for root hair development and for the symbioses with both rhizobial and mycorrhizal microbes. Mutants lacking DAHPS1 show altered root hair morphology, reduced symbiotic interactions, and downregulation of cell wall-related genes.

Summary: This study reports intercellular infection of the model legume Lotus japonicus by the IRBG74 strain and reveals the genetic requirements and differences in the pathways governing this process compared to intracellular infection. The results indicate a differential requirement for cytokinin signaling during intercellular rhizobial entry, highlighting distinct modalities of inter- and intracellular infection mechanisms in L. japonicus.
