Summary: Auxins are a class of plant hormones that play roles in the establishment and maintenance of arbuscular mycorrhizal symbiosis (AMS). In this study, it was found that the transcription factors ARFs and AUX/IAAs in the auxin signaling pathway co-regulate the transcription of auxin response genes, highlighting their importance in the early stage of AMS. Additionally, SlARF6 was found to negatively regulate AMF colonization, while SlIAA23 promoted AMS and phosphorus uptake by interacting with SlARF6. Furthermore, SlARF6 and SlIAA23 played opposing roles in strigolactone synthesis and accumulation in AMF-colonized tomato roots.

Summary: This study investigated the effect of arbuscular mycorrhizal fungus Paraglomus occultum on tomato under salt and non-salt stress conditions. It was found that AMF inoculation enhanced plant growth and salt resistance, and regulated the expression of stress-responsive genes.

Summary: A new product of AMF combined with different fungal species was found to enhance peanut salt, drought, and cold stress tolerance. AMF-inoculated plants displayed improved plant growth, photosynthetic efficiency, antioxidant system, and osmotic adjustment, while reducing damage to chloroplast thylakoids and mitochondria under stressful conditions. The metabolomic analysis showed that AMF altered numerous pathways associated with organic acids and amino acid metabolisms in peanut roots, which were further improved by osmolytes accumulation.

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: Our meta-analysis study suggests that AMF plays a pivotal role in the elimination of H2O2 through the upregulation of antioxidant enzymes but it depends upon the identity of AMF and plant species under drought stress conditions.

Summary: Inoculation of kenaf with AMF can enhance its tolerance to Cd, reduce Cd transport to aboveground plant tissues, and improve plant growth. AMF can also increase cell wall polysaccharide content, which helps bind Cd in the cell wall. Additionally, AMF can reduce the biological effectiveness of Cd by increasing soil pH and organic matter content.

Summary: The study found that warming significantly altered the AMF community structure, with higher AMF richness under the simulated warming chamber, but only at the elevation of 3,500 m. Warming did not affect other AMF alpha diversity indices. Glomus and Acaulospora were the dominant AMF genera in control and warming treatments at different elevations.

Summary: Casuarina glauca is an important coastal protection forest species that faces high salt stress all year round. Arbuscular mycorrhizal fungi (AMF) can promote the growth and salt tolerance of C. glauca under salt stress. This study investigated the effects of Rhizophagus irregularis on plant biomass, Na+ and Cl- distribution, and gene expression in C. glauca under NaCl stress through pot simulation experiments.

Summary: The study found that arbuscular mycorrhizal fungi (AMF) can improve plant tolerance to low-temperature stress by regulating proline accumulation. Nitric oxide (NO) plays an important signaling role in proline metabolism. The level of environmental nitrogen (N) affects AMF colonization and its contribution to plant resistance under low-temperature conditions.

Summary: Remediation of Hg-contaminated soil using mycorrhizal technology is environmentally friendly. However, the lack of research on the composition of arbuscular mycorrhizal fungi (AMF) in Hg-polluted soil hinders its biotechnological applications. This study sequenced the AMF communities in Hg mining areas and found that Glomeraceae was the dominant family. AMF diversity was influenced by soil Hg content, water content, and other soil properties.

Summary: The study investigates the mitigation effect of arbuscular mycorrhizal fungi (AMF) inoculation on heavy metal toxicity in Medicago truncatula under soil cadmium stress. The results show that AMF inoculation under Cd stress can enhance photosynthetic efficiency, increase plant biomass, decrease Cd and malondialdehyde (MDA) content, and improve soil physicochemical properties in M. truncatula. Non-targeted metabolite analysis reveals that AMF inoculation under Cd stress significantly upregulates the production of various amino acids in inter-root metabolism and increases organic acid and phytohormone synthesis.

Summary: A recent study shows that exogenous lipids can significantly stimulate the growth and colonization of AMF hyphae, leading to increased contact opportunities with plant roots. However, exogenous myristate inhibits the growth range and host tropism of germ tubes, thus impacting the nutrient exchange between symbionts.

Summary: The AMF community in poplar roots showed higher diversity and species composition in autumn than in spring. The formation of the symbiotic mycorrhizal system and the AMF community were influenced by season, host age, host species, and soil environmental factors. Differences in the communities could be explained by soil pH, total nitrogen, total phosphorus, total potassium, available potassium, and glomalin content. The change in the mycorrhizal symbiotic system was closely related to the growth and development of poplar trees.

Summary: Soil salinity negatively affects plant growth and yield, but biochar and arbuscular mycorrhizal fungus (AMF) can positively contribute to salt-stressed plant growth. This study investigated the effects of salt stress, AMF, and biochar applications on pepper plants, and found that increasing salt concentration decreased plant growth and AMF density while increasing soil electrical conductivity. Additionally, both biochar and AMF increased plant growth parameters and decreased membrane injury index values. The interaction between biochar and AMF improved microbial activity under salt stress conditions. Overall, using AMF and biochar together can potentially prevent salt stress damage in pepper growing.
