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.

A review and case study of Rhododendron moulmainense highlights the feasibility and adaptation of evergreen Rhododendron plants to current environmental challenges

mycolabadmin

Rhododendron moulmainense is a beautiful alpine flowering plant that has great potential for urban gardens and environmental restoration. While these plants typically struggle when moved from high mountains to lower altitudes due to heat and drought, researchers have discovered that special soil fungi living on their roots can help them survive better in these new environments. By understanding how these plants grow and propagate, scientists can help more people enjoy these colorful flowers while also using them to restore damaged ecosystems.

Various types of mycorrhizal fungi sequences detected in single intracellular vesicles

mycolabadmin

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.

Root anatomy governs bi-directional resource transfer in mycorrhizal symbiosis

mycolabadmin

This research reveals how the shape and structure of plant roots influence their ability to exchange nutrients and carbon with symbiotic fungi. The study shows that thicker roots face challenges in efficiently acquiring nutrients because they require more energy to transport nutrients across their thicker outer tissues. Fortunately, mycorrhizal fungi can help overcome this limitation when they position themselves deeper within the root structure, reducing the energy cost of moving nutrients to the plant’s vascular system.

Plasticity of symbiotroph-saprotroph lifestyles of Piloderma croceum associated with Quercus robur L

mycolabadmin

This research reveals that a common forest fungus called Piloderma croceum can switch between two different lifestyles: breaking down dead wood to obtain nutrients, and forming beneficial partnerships with living oak tree roots. The study shows that dead wood colonized by this fungus serves as a natural ‘seed bank’ for these fungi, allowing them to later colonize new trees. This discovery suggests that protecting deadwood in forests may indirectly help forests grow healthier by supporting the fungi that help trees absorb nutrients.

Research landscape of experiments on global change effects on mycorrhizas

mycolabadmin

Scientists conducted a comprehensive review of research studies examining how mycorrhizal fungi—fungi that help plants grow by living in their roots—respond to environmental changes caused by humans. They analyzed nearly 2,900 studies and found that most research focuses on just one environmental stress at a time, with very little studying how multiple stresses work together. The review identifies important gaps in our knowledge, particularly for emerging environmental threats like microplastics and for certain types of mycorrhizal fungi that haven’t been studied as much.

A high-quality genome assembly of Lactarius hatsudake strain JH5

mycolabadmin

Scientists have completed a detailed genetic blueprint of the red milk mushroom (Lactarius hatsudake), an edible and medicinal fungus that grows in pine forests. This mushroom is nutritious and has been shown to help with diabetes, boost immunity, and fight harmful bacteria. The new genetic map is much more complete and detailed than previous versions, which will help farmers grow these valuable mushrooms more reliably and sustainably, and could lead to developing better varieties.

Rhizosphere Bacterial Communities Alter in Process to Mycorrhizal Developments of a Mixotrophic Pyrola japonica

mycolabadmin

This study examines how bacterial communities in soil around plant roots change as fungi develop their associations with a mixotrophic plant called Pyrola japonica. The researchers found that bacterial diversity decreases when fungal colonization is at its peak, and these bacterial communities remain relatively stable even after the fungi begin to degenerate. The bacteria, particularly species from the Rhizobiales and Actinomycetales groups, appear to help support the fungal-plant partnership.

Legume-specific recruitment of rhizobia by hyphae of arbuscular mycorrhizal fungi

mycolabadmin

Fungi in soil create underground networks connecting plant roots, acting like highways for bacteria called rhizobia. These bacteria need to find the right plant partner to help fix nitrogen from the air. The fungi transport special chemical signals from each plant that guide the bacteria to their correct host, improving crop nitrogen nutrition naturally.

Halotolerant Endophytic Fungi: Diversity, Host Plants, and Mechanisms in Plant Salt–Alkali Stress Alleviation

mycolabadmin

Over 1.3 billion hectares of farmland worldwide suffer from excess salt and alkalinity, drastically reducing crop yields. Special fungi that live inside plant tissues can help crops survive in these harsh conditions without harming them. These fungi work by helping plants manage salt accumulation, boost their natural defenses, and produce protective compounds. While laboratory tests show promising results with yield increases up to 40%, practical field application remains challenging due to environmental variables.
