Mycorrhizal fungus BJ1, a new species of Tulasnella sp.: its biological characteristics and promoting effect on seed germination of Bletilla striata

mycolabadmin

Researchers discovered a new type of fungus called Tulasnella sp. BJ1 that forms beneficial partnerships with Bletilla striata, a traditional Chinese medicinal plant. When this fungus was used with the plant’s seeds, germination rates and seedling growth improved significantly compared to seeds grown alone. The fungus helps by producing growth-promoting substances like plant hormones and breaking down nutrients that the developing plants can absorb. This finding offers a practical method to grow more B. striata plants efficiently for medicinal use.

Phylogeny of Aspergillus section Circumdati and inhibition of ochratoxins potential by green synthesised ZnO nanoparticles

mycolabadmin

Researchers identified four species of Aspergillus fungus that contaminate crops and produce poisonous compounds called ochratoxins. They found that specially made zinc oxide nanoparticles, created using an environmentally friendly method with basil extract, can significantly reduce the amount of ochratoxins produced by these fungi. This discovery could help protect agricultural products from contamination and improve food safety.

Spatial Phylogenetics Reveals Endemism Hotspots and Conservation Priorities in Chinese Asteraceae

mycolabadmin

This study examined over 1000 species of sunflower family plants (Asteraceae) across China using evolutionary relationships and geographic data. Researchers discovered three regions with exceptional plant diversity and unique evolutionary history deserving protection: the Tianshan-Altai Mountains in the northwest, the Hengduan Mountains in the southwest, and Taiwan Island. These areas preserve ancient plant lineages found nowhere else on Earth, making them conservation priorities.

Additions to the Entoloma (Agaricales, Entolomataceae) from China: Description of five species with one new to science

mycolabadmin

Scientists studying mushrooms in China’s Qilian Mountains discovered five species of Entoloma mushrooms, including one completely new to science called Entoloma griseopileum. This gray mushroom grows on wood rather than soil, unlike most similar species. The research used both traditional microscopic examination and modern DNA analysis to identify and describe these mushrooms, adding to our knowledge of fungal diversity in this important biodiversity region.

Molecular identification and mycotoxins analysis of some fungal isolates from postharvest decayed apple in Qena, Egypt

mycolabadmin

Apples stored after harvest can be infected by blue mold fungi that produce toxic substances called mycotoxins. Researchers in Egypt identified five fungal strains from rotted apples and measured the amounts of two dangerous toxins they produce. The findings show that these fungi can cause significant food safety risks and economic losses, highlighting the need for better storage and handling practices.

Targeted long-read sequencing analysis and antifungal susceptibility profiles of Sporothrix schenckii isolates from Thailand

mycolabadmin

Researchers in Thailand studied a fungal infection called sporotrichosis caused by Sporothrix schenckii, which infects both cats and humans. Using advanced DNA sequencing technology from Oxford Nanopore, they identified and classified 26 fungal samples and tested how well common antifungal medications worked against them. They found that calmodulin gene sequencing was better than the standard ITS test for identifying the fungus species, and that about one-third of the samples showed reduced sensitivity to the main treatment drug, itraconazole.

Morphological and Phylogenetic Characterization of Endophytic Fungi Isolated from Brown Algae (Phaeophyceae) in Korea

mycolabadmin

Researchers in Korea isolated and identified three types of fungi never before recorded in the country that live inside brown seaweed. These fungi were found in Sargassum species collected from Korean coastal areas and were identified using DNA analysis and microscopy. The discovery reveals that Korean seaweed harbors diverse fungal communities that may produce useful compounds for medicine and agriculture, highlighting the unexplored potential of marine ecosystems.

Potential Protective Role of Amphibian Skin Bacteria Against Water Mold Saprolegnia spp

mycolabadmin

Frog populations are declining due to various diseases and environmental challenges. This research discovered that bacteria living on frog skin can protect against harmful water molds called Saprolegnia that attack amphibian eggs. Scientists found that different types of bacteria, particularly Bacillus species, can inhibit the growth of these water molds. The protective effect was strongest in nutrient-poor conditions similar to natural water environments, suggesting that the bacterial symbiosis with frogs may be an important defense mechanism.

From seagrass roots to saline soils: discovery of two new genera in Lulworthiales (Sordariomycetes) from osmotically stressed habitats

mycolabadmin

Researchers discovered two previously unknown types of fungi living in extreme saltwater and salty soil environments. One fungus lives symbiotically within seagrass roots in Mauritius, while the other was found in saline soils in the Czech Republic. These findings show that fungi traditionally thought to live only in marine environments actually have a broader range of habitats and ecological roles than previously understood.

New species and records of Trichoderma isolated as mycoparasites and endophytes from cultivated and wild coffee in Africa

mycolabadmin

Scientists discovered 16 different species of Trichoderma fungi living in coffee plants and on coffee rust fungus in Africa, including four previously unknown species. These beneficial fungi show promise as natural pest controllers for coffee leaf rust, a major disease threatening coffee production worldwide. Interestingly, the same fungi were not found in coffee plants surveyed in Brazil, suggesting they may be unique to African coffee populations. This discovery could help farmers control this destructive disease without chemicals.
