Mitochondrial genome characterization, evolution and intron dynamics of the entomopathogenic genus Cordyceps

mycolabadmin

This research examined the genetic instruction manuals (mitochondrial DNA) of seven different Cordyceps fungal species. Scientists found that these fungi have varying amounts of genetic material, primarily due to differences in introns—sections that can be inserted or removed from genes. By comparing their genomes, researchers clarified how different Cordyceps species are related to each other evolutionarily, providing better tools for identifying and classifying these medically valuable fungi.

Pseudobaorangia (Boletaceae, Boletales), a new genus for Boletus lakhanpalii

mycolabadmin

Scientists studying mushrooms collected in China’s Baima Snow Mountain identified a bolete species that was previously misclassified. Using DNA analysis combined with detailed microscopic examination, they determined this mushroom was distinct enough to warrant creation of a brand new genus called Pseudobaorangia. This discovery helps clarify the evolutionary relationships and proper classification of this rare mountain-dwelling mushroom species.

Comparative genome analysis of patulin-producing Penicillium paneum OM1 isolated from pears

mycolabadmin

Researchers sequenced the complete genome of a mold called Penicillium paneum that produces a toxic substance called patulin, which contaminates apples and pears. They found all 15 genes responsible for making patulin and discovered the mold has similar genetic patterns to other patulin-producing fungi. This information could help scientists develop better ways to prevent patulin contamination on fruit crops and improve food safety.

Sporothrix is neglected among the neglected

mycolabadmin

Sporotrichosis is a fungal infection caused by Sporothrix species that usually affects the skin but can spread to joints, lungs, and eyes. While traditionally spread through plant material during gardening, the disease has increasingly spread between cats and humans through bites and scratches, particularly in South America and other regions. The fungus is developing resistance to common antifungal drugs, and scientists worry climate change could expand where this disease occurs worldwide.
