Slime molds (Myxomycetes) causing a “disease” in crop plants and cultivated mushrooms

mycolabadmin

Slime molds are not true plant diseases but can harm crops by covering leaves and blocking sunlight and water loss. These organisms prefer wet, organic-rich environments and are particularly problematic in mushroom farming. Farmers can prevent problems by managing moisture, improving ventilation, and removing affected materials, with chemical sprays available as backup options when needed.

Draft genome sequence data of Fusarium verticillioides strain REC01, a phytopathogen isolated from a Peruvian maize

mycolabadmin

Researchers sequenced the genome of a fungus that causes rot disease in corn plants, specifically from samples found in Peru. The fungus produces toxins that harm both human and animal health and reduces crop yields. By analyzing the fungus’s genetic code and comparing it with other strains, scientists can better understand how it causes disease and develop better strategies to protect corn crops.

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

mycolabadmin

Researchers in China identified a fungus called Colletotrichum kahawae causing a serious disease called anthracnose in buckwheat crops for the first time. The fungus also has the potential to infect other important crops like wheat, oats, potatoes, and corn. Scientists determined the ideal conditions for this fungus to grow and tested its ability to infect different plants. This discovery will help farmers develop better strategies to prevent and manage this disease in buckwheat and other crops.

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.

Complete genome sequence analysis of Boeremia exigua, a fungal pathogen causing leaf spot disease of Panax notoginseng

mycolabadmin

Panax notoginseng, a valuable traditional Chinese medicinal plant, has been affected by a fungal leaf spot disease caused by Boeremia exigua. Researchers sequenced the complete genome of this fungal pathogen for the first time, discovering important genes responsible for its ability to infect plants, including enzymes that break down plant cell walls and proteins that help it evade plant defenses. This genetic information provides a foundation for developing better strategies to protect these valuable medicinal plants from disease.

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

mycolabadmin

Researchers in China discovered that a fungus called Colletotrichum kahawae is causing a serious disease called anthracnose on buckwheat crops in Yunnan Province. This is the first time this particular fungus has been identified on buckwheat in China. Scientists studied how the fungus grows and found it prefers temperatures around 25°C and neutral pH levels. The fungus can also infect other important crops like wheat, corn, potatoes, and oats, which could pose a significant threat to agriculture in the region.

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

mycolabadmin

Researchers in China discovered that a fungus called Colletotrichum kahawae is causing a serious disease called anthracnose on buckwheat crops in Yunnan Province. This is the first time this particular fungus has been found on buckwheat, though it’s already known for causing disease on coffee plants worldwide. The scientists characterized how this fungus grows best under certain conditions and tested whether it could infect other important crops like corn, wheat, and potatoes, finding it could potentially harm these crops too.

Complete genome sequence of Diaporthe vaccinii Shear, a fungal isolated from blueberry

mycolabadmin

Scientists sequenced the complete genetic blueprint of Diaporthe vaccinii, a harmful fungus that damages blueberry plants and costs farmers significant money. Using advanced DNA sequencing technology, they assembled a high-quality genetic map of the fungus to better understand how it causes disease. This genetic information could help researchers develop better ways to protect blueberry crops from this destructive pathogen.

Transposons and accessory genes drive adaptation in a clonally evolving fungal pathogen

mycolabadmin

Researchers studied how a fungal plant pathogen called Fusarium oxysporum rapidly adapts to new environments by analyzing genetic changes during repeated passages through tomato plants and laboratory media. They discovered that jumping genes (transposons) were responsible for most mutations driving adaptation, and surprisingly found that genes located in specialized ‘accessory’ regions of the fungus’s genome controlled important functions like growth and virulence. This research reveals how fungal pathogens can evolve quickly to become better competitors or invaders.

Morphology and phylogeny reveal two new species of pestalotioid fungi associated with hawthorn in Northeast China

mycolabadmin

Researchers discovered two previously unknown fungal species living on hawthorn trees in Northeast China. Through detailed microscopic examination and genetic analysis, they identified these as Sporocadus changchunensis and S. crataegicola. Testing showed these fungi can cause disease spots on hawthorn leaves, suggesting they may pose risks to hawthorn crops. This finding helps expand our understanding of fungal species and their role in plant health.
