Phytohormones and volatile organic compounds, like geosmin, in the ectomycorrhiza of Tricholoma vaccinum and Norway spruce (Picea abies)

mycolabadmin

This research examines how a fungus (Tricholoma vaccinum) and spruce tree communicate through chemical signals. The fungus produces unique compounds including geosmin (the earthy smell of soil after rain), limonene (lemon scent), and plant hormones. These chemicals help the fungus and tree establish their beneficial partnership by affecting how the fungus grows and branches around the tree roots. The findings show that these chemical signals are crucial for successful formation of the mycorrhizal relationship.

Various types of mycorrhizal fungi sequences detected in single intracellular vesicles

mycolabadmin

Scientists discovered that two different types of beneficial fungi can live together inside the same tiny storage structure (vesicle) within plant roots. They designed new genetic tools to identify these fungi more accurately. This finding suggests that plants may have more complex fungal partnerships than previously understood, which could help us better understand how plants get nutrients from soil and improve agriculture.

Can the DSE Fungus Exserohilum rostratum Mitigate the Effect of Salinity on the Grass Chloris gayana?

mycolabadmin

Researchers tested whether a beneficial fungus called Exserohilum rostratum could help a grass species called Rhodes grass survive in salty soil conditions. The fungus was found to tolerate salt well and helped the grass maintain better nutrient balance, but these benefits were limited and didn’t fully protect the grass from the negative effects of high salt levels. This suggests that while the fungus can be helpful, its effectiveness depends on specific conditions and salt concentrations.

Can the DSE Fungus Exserohilum rostratum Mitigate the Effect of Salinity on the Grass Chloris gayana?

Researchers tested whether a fungus called Exserohilum rostratum could help a forage grass called Rhodes grass survive in salty soil. The fungus did tolerate salt and helped the grass maintain better nutrient balance under salt stress, but it couldn’t fully protect the grass from severe salinity. The benefits were most noticeable under moderate salt conditions, suggesting the fungus works best in less extreme environments.

Various types of mycorrhizal fungi sequences detected in single intracellular vesicles

Researchers discovered that single fatty droplet-like structures inside plant roots can contain genetic material from multiple types of fungi, both Glomeromycotina and Mucoromycotina. They developed new molecular tools to detect and identify these fungi without bias. This finding suggests fungi may live together more intimately than previously thought, which could help us better understand how plants get nutrients from fungal partners in soil.

PEG-Mediated Protoplast Transformation of Penicillium sclerotiorum (scaumcx01): Metabolomic Shifts and Root Colonization Dynamics

mycolabadmin

Scientists developed a new method to genetically modify a beneficial fungus called Penicillium sclerotiorum by removing its cell wall and introducing new genes. They added a glowing green marker (GFP) to track the fungus as it colonizes tomato plant roots. The study shows that enzymatic treatment of seeds significantly improves how well the fungus attaches to roots, potentially helping plants grow better while revealing how the genetic modification affects the fungus’s internal chemistry.

Enhancing consistency in arbuscular mycorrhizal trait-based research to improve predictions of function

mycolabadmin

This review addresses how to better study fungal partners that help plants grow by proposing standardized methods to measure fungal characteristics. These fungi form beneficial partnerships with plant roots, improving nutrient uptake and soil health. By developing consistent measurement approaches and databases of fungal traits, scientists can better predict how these fungi affect plants and ecosystems.

Composition and Biodiversity of Culturable Endophytic Fungi in the Roots of Alpine Medicinal Plants in Xinjiang, China

mycolabadmin

Scientists studied special fungi that live inside the roots of two rare alpine medicinal plants found in China’s high mountains. They discovered that these plants host over 400 different types of fungi, including a special type called dark septate fungi that make up about half of all the fungi found. Different plant species and different mountain locations had different combinations of fungi, suggesting these fungi help the plants survive in the harsh, cold mountain environment.

The influence of mycorrhizal hyphal connections and neighbouring plants on Plantago lanceolata physiology and nutrient uptake

mycolabadmin

Fungi that live in soil form partnerships with plant roots and can extend underground networks connecting multiple plants. In this study, plants with access to expanded fungal networks captured more carbon through photosynthesis, accumulated more nutrients like phosphorus and zinc, and released more carbon into the soil. However, whether neighboring plants were present or what type they were did not significantly change these benefits, suggesting that soil exploration volume matters more than plant-to-plant connections through fungal networks.

Newly Designed Fluorescence In Situ Hybridization Probes Reveal Previously Unknown Endophytic Abilities of Tuber magnatum in Herbaceous Plants

mycolabadmin

Scientists discovered that Italian white truffles (Tuber magnatum) can live inside the roots of common herbaceous plants like sedges, not just the oak and poplar trees where they are typically found. Using special fluorescent probes and advanced microscopy, researchers confirmed the presence of active truffle threads inside these plants, particularly in spring. This discovery challenges our understanding of how truffles interact with their environment and may explain why truffle cultivation has been difficult, suggesting they employ more diverse survival strategies than previously thought.
