Rhizoctonia solani causes okra (Abelmoschus esculentus) seedling damping-off in South China with biological characterization and fungicide sensitivity profiling

mycolabadmin

Researchers identified Rhizoctonia solani as the fungus causing a serious disease in okra seedlings in southern China that was destroying about 35% of crops. The fungus dies when exposed to high temperatures (45-48°C) and grows best at about 28°C. Among seven tested antifungal treatments, a combination of trifloxystrobin and tebuconazole was most effective at controlling the pathogen, providing farmers with practical strategies for managing this crop disease.

Would global warming bring an increase of invertebrate-associated cutaneous invasive fungal infections?

mycolabadmin

This paper discusses how invertebrate bites (from insects, spiders, and other small creatures) can transmit dangerous fungal infections to humans by directly injecting fungi into the skin. These infections are rare but serious, often causing tissue death and requiring amputation. As global warming increases temperatures, insect populations will expand into new areas, become more aggressive, and fungi may adapt to survive at higher temperatures, potentially making these infections more common and dangerous in the future.

Compatible traits of oleaginous Mucoromycota fungi for lignocellulose-based simultaneous saccharification and fermentation

mycolabadmin

Scientists tested different types of fungi to see which ones are best at producing oils that can be turned into biofuel while breaking down plant material. They found that Lichtheimia corymbifera can survive at high temperatures and produce useful enzymes, making it the best candidate. The study helps identify which fungi should be used in industrial processes to make sustainable biofuels from agricultural waste.

Single-center retrospective analysis of 454 culture-positive patients with tinea capitis and measurement of pathogens regarding thermal tolerance at 37°C

mycolabadmin

Tinea capitis, commonly known as scalp ringworm, is a fungal infection that primarily affects children but can also occur in adults, especially postmenopausal women. This study of 454 patients in Hangzhou, China found that the most common cause is Microsporum canis (a fungus from cats and dogs), representing a shift from previous decades when different fungi were dominant. Researchers tested how well these fungi grow at human body temperature (37°C) versus room temperature, finding that most fungi adapt well to the warmer temperature, particularly Nannizzia gypsea, which grew equally well at both temperatures. Treatment typically involves oral antifungal medications like terbinafine or itraconazole, sometimes combined with topical treatments or steroids for inflammatory cases.

Enhanced Heat Resistance in Morchella eximia by Atmospheric and Room Temperature Plasma

Researchers used a special plasma technology to create heat-resistant strains of morel mushrooms that can thrive at higher temperatures. These mutant strains showed enhanced natural defense systems with more antioxidant enzymes and protective compounds. This breakthrough could help farmers grow more morels successfully despite rising temperatures from climate change, while maintaining their nutritional and medicinal benefits.

The fungal STRIPAK complex: Cellular conductor orchestrating growth and pathogenicity

mycolabadmin

The STRIPAK complex is a cellular control hub found in fungi that acts like a conductor orchestrating multiple cellular processes essential for fungal growth and the ability to cause disease. Scientists have discovered that this complex is highly conserved across different fungal species and regulates critical virulence factors like melanin production and capsule formation in pathogenic fungi. Because the fungal version differs from the human version, it presents a promising target for developing selective antifungal medications. Understanding how STRIPAK works provides insights into how fungi cause infections and could lead to new treatment strategies.

Elucidation of Twig Canker and Shoot Blight (TCSB) in Peach Caused by Diaporthe amygdali in the North of Italy in Emilia-Romagna

mycolabadmin

Peach trees in northern Italy are suffering from a disease called twig canker and shoot blight caused by a fungus called Diaporthe amygdali. This research identified and characterized this fungus from affected orchards, studying how it grows at different temperatures to better understand and control the disease. The fungus grows best around 23-24°C and can survive extreme heat above 50°C. These findings will help fruit growers develop better strategies to protect their peach crops.

Compatible traits of oleaginous Mucoromycota fungi for lignocellulose-based simultaneous saccharification and fermentation

mycolabadmin

Researchers tested nine types of fungi to find which ones are best at producing oils from plant waste for making biofuels. They tested how well each fungus could handle higher temperatures and break down cellulose, which is the main component of plant material. Lichtheimia corymbifera was the clear winner because it could grow at higher temperatures while still breaking down plant material efficiently, making it ideal for the combined process of breaking down and fermenting plant waste.
