Morphological and Molecular Characterization of Lasiodiplodia theobromae Causing Stem Gummosis Disease in Rubber Trees and Its Chemical Control Strategies

mycolabadmin

Rubber trees in China experienced a serious stem gummosis disease that caused bark cracking and latex leakage in 2023. Scientists identified the fungus Lasiodiplodia theobromae as the cause through laboratory and molecular tests. They successfully treated the disease using a combination of copper-based fungicides applied to tree trunks and roots, preventing further damage to the trees.

Mycoviruses: Antagonistic Potential, Fungal Pathogenesis, and Their Interaction with Rhizoctonia solani

mycolabadmin

This comprehensive review explores how viruses that infect fungi, called mycoviruses, could help farmers control rice diseases. Rice sheath blight caused by the fungus Rhizoctonia solani causes significant crop losses worldwide. Scientists have discovered that certain mycoviruses can weaken this pathogenic fungus, making them promising biological alternatives to chemical fungicides that can harm the environment and encourage disease resistance.

Current taxonomic status of the cultivable and uncultivable Paracoccidioides species

mycolabadmin

Paracoccidioides are fungi that cause serious infections in humans and dolphins. Scientists have recently reorganized and renamed these fungi into five different species—three that can be grown in labs and two that cannot. Some previously named species turned out to be invalid due to naming rule violations. This article explains the correct names and classifications that doctors and researchers should use.

Phylogenetic diversity of Colletotrichum species (Sordariomycetes, Glomerellales, Glomerellaceae) associated with plant diseases in Thailand

mycolabadmin

Researchers identified eight species of Colletotrichum fungi causing plant diseases in Thailand. They discovered two completely new species and found these fungi on 13 additional plant hosts previously unknown. Using DNA analysis, they confirmed the identity of each fungal species and documented their characteristics. This work helps farmers and scientists better identify and manage these damaging plant pathogens.

Essential Oils as an Antifungal Alternative for the Control of Various Species of Fungi Isolated from Musa paradisiaca: Part I

mycolabadmin

Researchers tested six essential oils from common kitchen herbs to see if they could prevent banana spoilage caused by fungi. They found that cinnamon oil was especially effective, stopping fungal growth at relatively low concentrations. This research suggests that natural essential oils could replace harsh chemical fungicides in farming, making bananas safer for consumers and better for the environment.

Diaporthe foeniculina and D. eres, in addition to D. ampelina, may cause Phomopsis cane and leaf spot disease in grapevine

mycolabadmin

Researchers found that three different fungal species, not just one, cause a disease called Phomopsis cane and leaf spot in grapevines grown in Southern Europe. While Diaporthe ampelina remains the primary culprit, two other species (D. eres and D. foeniculina) can also cause the same disease symptoms. Interestingly, these different fungi prefer different temperatures for growth, which means farmers may need to adjust their disease management strategies based on which species is present in their vineyards.

Two new species of Stilbochaeta (Chaetosphaeriaceae, Chaetosphaeriales) from freshwater and terrestrial habitats in China

mycolabadmin

Scientists discovered two previously unknown species of fungi called Stilbochaeta in China. They used DNA analysis and microscopic examination to confirm these were new species distinct from known fungi. One species was found in a freshwater stream, while the other was discovered on decaying wood in a forest. This discovery increases the known diversity of these small fungi and shows how important it is to study different ecosystems around the world.

Biocontrol of Seedborne Fungi on Small-Grained Cereals Using Bacillus halotolerans Strain B33

mycolabadmin

Researchers discovered that a bacterium called Bacillus halotolerans strain B33 can effectively prevent harmful fungi from damaging cereal seeds like wheat, barley, oats, and rye. When seeds were treated with this beneficial bacterium, it successfully eliminated or greatly reduced three dangerous fungal pathogens while also helping the seeds germinate better. This natural approach offers a promising environmentally-friendly alternative to chemical fungicides for protecting grain crops.

First occurrence of feline sporotrichosis in a metropolitan area of Central-West Brazil

mycolabadmin

Researchers in Brazil discovered the first case of a serious fungal infection called sporotrichosis in a domestic cat in the Goiania metropolitan area. The infection was caused by a fungus called Sporothrix brasiliensis, which can spread from cats to humans through scratches and bites. This finding is important because it shows the disease is spreading to new regions of Brazil that previously didn’t have confirmed cases, and suggests residents need to be cautious around stray cats.

Various types of mycorrhizal fungi sequences detected in single intracellular vesicles

mycolabadmin

Scientists discovered that two different types of beneficial fungi can live together inside the same tiny storage structure (vesicle) within plant roots. They designed new genetic tools to identify these fungi more accurately. This finding suggests that plants may have more complex fungal partnerships than previously understood, which could help us better understand how plants get nutrients from soil and improve agriculture.
