Comparative mitogenomic analysis reveals variations and evolution of ectomycorrhizal fungal Strobilomyces

mycolabadmin

Scientists sequenced and analyzed the genetic material of five species of Strobilomyces mushrooms, which form important relationships with trees in forests. They discovered these mushrooms have relatively similar genetic blueprints with some regional variations in gene organization. Some species from Vietnam have slightly different gene arrangements than those from the USA, suggesting their evolutionary history is linked to geography. This research helps scientists better understand how these important fungi evolved and are related to other mushroom species.

Metabarcoding Unveils Seasonal Soil Microbiota Shifts and Their Influence on Boletus edulis and Boletus reticulatus Mycelium in Quercus robur Stands

mycolabadmin

This research studied how soil bacteria and fungi change across fall months in oak forests in Spain and how these changes relate to the growth of valuable edible mushrooms (Boletus species). Scientists used DNA analysis to identify thousands of different microorganisms in the soil. They found that September had the most diverse microbial communities, October showed a decline, and November saw partial recovery. Importantly, Boletus mycelium showed different patterns of growth depending on the month and was associated with specific beneficial bacteria and fungi.

The contribution of tropical long-term studies to mycology

mycolabadmin

Scientists have long known less about fungi in tropical regions compared to temperate areas. This paper highlights how studying the same fungal communities over many years in tropical locations like Guyana reveals important discoveries about fungal diversity, including new species and unique ecological relationships. The authors show that public scientific databases contain far fewer fungal records from tropical regions than non-tropical ones, suggesting we may be missing crucial information about fungal biodiversity and how to protect it.

Mycobiome of low maintenance iconic landscape plant boxwood under repeated treatments of contact and systemic fungicides

mycolabadmin

This study examined how different fungicide treatments affect the beneficial and harmful fungi living on boxwood plants. Researchers found that repeated applications of chlorothalonil-based fungicides reduced many beneficial fungi while having minimal effect on harmful pathogens, and that fungi became less sensitive to the same fungicide over time. The findings suggest that choosing the right fungicide and application method is important for maintaining plant health and preventing fungicide resistance.

Mycelial communities associated with Ostrya carpinifolia, Quercus pubescens and Pinus nigra in a patchy Sub-Mediterranean Karst woodland

mycolabadmin

This research studied how fungi living in soil connect to different tree roots in a rocky Mediterranean forest in Slovenia. Scientists found that different tree species have their own preferred fungal partners, though some fungi work with multiple trees. The fungi with longer connections through soil were more common under pine trees, while fungi with shorter reach were more common under oak and hornbeam trees.
