Morphological and molecular identification of endophytic fungi from roots of epiphyte orchid Aerides odorata Lour in Sabah

mycolabadmin

Scientists studied fungi living inside the roots of a rare fragrant orchid called Aerides odorata. Using advanced microscopy and DNA analysis, they identified seven different types of fungi that help the orchid absorb nutrients and grow. These fungi form special structures called pelotons inside the plant’s root cells. This research helps scientists understand how to better grow and protect endangered orchids.

Cellular anatomy of arbuscular mycorrhizal fungi

mycolabadmin

This comprehensive review explains the unique cellular structure of arbuscular mycorrhizal fungi, which form vast underground networks connecting plants to soil nutrients. These fungi are remarkable because their hyphae lack internal walls, allowing nutrients and organelles to flow freely throughout their continuous cytoplasm. By synthesizing current knowledge about how these fungi are organized and function at the cellular level, the authors highlight how this organization enables the complex nutrient exchange that supports plant growth and ecosystem health worldwide.

Arbuscular mycorrhizal fungi colonization facilitates nitrogen uptake in cotton under nitrogen-reduction condition

mycolabadmin

This study shows that beneficial soil fungi (arbuscular mycorrhizal fungi) can help cotton plants absorb more nitrogen from soil, especially when nitrogen fertilizer is reduced. The fungi form partnerships with cotton roots and extend into the soil with thread-like structures that absorb nitrogen and transport it to the plant. The research demonstrates that reducing nitrogen fertilizer while using these beneficial fungi could improve crop growth while reducing environmental pollution from fertilizer runoff.

Fungal symbiont Mycena complements impaired nitrogen utilization in Gastrodia elata and supplies indole-3-acetic acid to facilitate its seed germination

mycolabadmin

Gastrodia elata is a special orchid that cannot make its own food and must rely entirely on a fungal partner called Mycena. Scientists discovered that the orchid has lost genes needed to use nitrogen and make growth hormones, while the fungus Mycena has kept these genes. By providing nitrogen and a hormone called auxin, the fungus helps the orchid seeds germinate and grow.

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.

Microbial communities inhabiting the surface and gleba of white (Tuber magnatum) and black (Tuber macrosporum) truffles from Russia

mycolabadmin

This research identifies the various microorganisms living inside truffles, particularly Tuber magnatum (white truffle) and Tuber macrosporum (black truffle). The study found that a yeast-like fungus called Geotrichum consistently lives in both truffle types and likely helps with spore dispersal through smell-producing compounds. The researchers discovered that different parts of the truffle have different microbial communities, which explains why truffles have such unique flavors and aromas.
