Identification of Pseudocercospora mori as the causal agent of grey leaf spot disease in mulberry (Morus atropurpurea) from various localities in Guangdong Province, China

mycolabadmin

Researchers identified a fungus called Pseudocercospora mori as the cause of grey leaf spot disease in mulberry trees grown in Guangdong Province, China. Using advanced DNA sequencing and traditional microscopy, they confirmed this pathogen causes dark spots on mulberry leaves that reduce quality and yield, harming the silk industry that relies on mulberry leaves to feed silkworms. The study developed specific detection methods to help farmers identify and manage this disease in their orchards.

Hidden treasures of herbaria – even small collections contain a wealth of diversity: the powdery mildews of the North Carolina State Larry F. Grand Mycological Herbarium

mycolabadmin

Scientists examined preserved powdery mildew samples stored in a university herbarium and discovered four previously unknown fungal species using DNA analysis. The study shows that even small museum collections contain valuable hidden biodiversity that cannot be discovered through visual examination alone. This research highlights why it is important to preserve and maintain herbarium collections rather than discard them due to space or funding constraints, as they serve as crucial resources for understanding fungal diversity and disease.

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.

Unveiling Species Diversity of Plectosphaerellaceae (Sordariomycetes) Fungi Involved in Rhizome and Root Rots of Ginger in Shandong Province, China

mycolabadmin

Researchers in China identified four fungal species that cause serious diseases in ginger plants, destroying the underground rhizomes and roots. Two of these species are newly discovered and named after the ginger host and the region where they were found. These fungi are major threats to ginger farming in China’s largest ginger-producing region, causing crop losses ranging from 20-100%.

Seimatosporium chinense, a Novel Pestalotioid Fungus Associated with Yellow Rose Branch Canker Disease

mycolabadmin

Researchers identified a new fungal disease affecting ornamental yellow roses in China. The disease causes branch cankers (sunken lesions) and was caused by a previously unknown fungus species named Seimatosporium chinense. By examining the fungus under microscopes and analyzing its DNA, scientists distinguished this new species from similar fungi. This discovery helps understand and manage diseases affecting ornamental rose plants.

The complete mitochondrial genome of medicinally important wood-decaying fungus Tyromyces fissilis within the family Incrustoporiaceae, Polyporales

mycolabadmin

Scientists have sequenced the complete genetic blueprint of a wood-rotting mushroom called Tyromyces fissilis for the first time. This fungus is medicinally important and has the ability to break down wood and produce therapeutic compounds. By analyzing its mitochondrial genome and comparing it with related fungi, researchers found that it is most closely related to another fungus called Phlebia radiata and belongs to a previously understudied fungal family. This genetic information will help scientists better understand how these fungi are related and may lead to new medical applications.

First Report of Colletotrichum kahawae Causing Anthracnose on Buckwheat (Fagopyrum tataricum) in China and Biological Characterization of the Pathogen

mycolabadmin

Researchers discovered a serious fungal disease affecting buckwheat crops in China caused by Colletotrichum kahawae, a fungus that ranks among the world’s most damaging plant pathogens. Through laboratory tests, they identified the fungus and determined its optimal growth conditions and which other crops it can infect, including wheat, oats, potatoes, and maize. This is the first time this particular fungus has been reported on buckwheat, and the findings will help farmers develop strategies to prevent and manage the disease.

Clonostachys rosea, a Pathogen of Brown Rot in Gastrodia elata in China

mycolabadmin

Researchers in China identified a fungus called Clonostachys rosea as the cause of brown rot disease affecting Gastrodia elata (Tian Ma), an important medicinal orchid plant. The disease causes brown spots on tubers that expand and darken, significantly reducing crop yield and quality. The study involved detailed examination of the fungus under microscopes, genetic analysis, and confirmation that the fungus could cause disease in healthy plants. These findings will help farmers prevent and control this disease through proper soil management and selection of healthy seed tubers.

Morpho-Molecular Identification and Pathogenic Characterization of Fusarium and Colletotrichum Species Associated with Intercropped Soybean Pod Decay

mycolabadmin

This study identified dangerous fungi causing soybean pod decay in Southwestern China’s intercropping farms. Researchers found 8 types of Fusarium and 6 types of Colletotrichum fungi infecting soybean pods, with some species being discovered as soybean pathogens for the first time. Laboratory tests showed that certain species like F. proliferatum and C. fructicola cause severe damage to both soybean pods and seeds, potentially reducing crop yields and seed quality significantly.

Four Unrecorded Species of Endophytic Diaporthe (Sordariomycetes) in Korea

mycolabadmin

Researchers in Korea discovered four types of fungi living inside plants without causing harm, called endophytic fungi. These fungi belong to a genus called Diaporthe and were identified using DNA analysis and microscopic examination. The study helps us understand the hidden diversity of fungi living in Korean plants and could lead to discovering new medicines or ways to control plant diseases.
