Mycorrhizal associations drive plant community diversity and ecosystem functions. Arbuscular mycorrhiza (AM) and ectomycorrhiza (EcM) are two widespread mycorrhizal types and are thought to differentially affect plant diversity and productivity by nutrient acquisition and plant-soil feedback. However, it remains unclear how the mixture of two mycorrhizal types influences tree diversity, forest biomass, and their relationship at large spatial scales.

Orchid mycorrhizal fungi (OMF) associations in the Orchidaceae are thought to have been a major driver of diversification in the family. In the terrestrial orchid tribe Diurideae, it has long been hypothesised that OMF symbiont associations may reflect evolutionary relationships among orchid hosts. Given that recent phylogenomic efforts have been unable to fully resolve relationships among subtribes in the Diurideae, we sought to ascertain whether orchid OMF preferences may lend support to certain phylogenetic hypotheses.

The integration of endomycorrhizal fungi into agricultural practices as inoculum offers the potential to improve plant productivity while reducing reliance on expensive chemical fertilizers, which are not only economically costly but also detrimental to the environment. Mycorrhizal fungi play a crucial role in facilitating plant access to essential mineral elements (such as Phosphorus, Potassium, etc.) and water, particularly in soils characterized by arid and semi-arid conditions.

Article Synopsis
- Anthropogenic activities are increasing the levels of toxic metals in the environment, affecting biodiversity, human health, and food security through pollution of soil and water.
- Bioremediation, particularly using mycorrhizal and endophytic fungi, offers an eco-friendly and cost-effective way to clean up metal-contaminated soil compared to traditional methods.
- Mycorrhizal fungi help plants manage metal absorption and enhance their growth, while certain endophytic fungi, like Metarhizium, have developed unique methods to specifically target and remove pollutants like methylmercury, making them suitable for large-scale soil remediation.

Article Synopsis
- The study examines the relationship between mycorrhizal types, specifically arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) plants, and their differences in drought tolerance.
- A global dataset of 1457 woody species was analyzed, revealing that evolutionary history and biogeography affect hydraulic traits in these plants.
- Findings indicate that AM angiosperms are less drought-tolerant than EcM angiosperms in wetter areas, while AM gymnosperms outperform EcM gymnosperms in dry conditions; overall, AM species show greater variation in hydraulic traits compared to EcM species.
