Whole-genome sequencing of global forest pathogen Diplodia sapinea causing pine shoot blight

mycolabadmin

Scientists have sequenced the complete genome of Diplodia sapinea, a fungus that causes serious disease in pine trees worldwide. This fungus normally lives harmlessly inside healthy pine trees but becomes dangerous during stressful conditions like droughts or storms. The new genome information will help scientists understand how this pathogen works and develop better ways to prevent and control the disease in forests.

Saprotrophic Arachnopeziza Species as New Resources to Study the Obligate Biotrophic Lifestyle of Powdery Mildew Fungi

mycolabadmin

Scientists have discovered that two types of fungi called Arachnopeziza species are the closest living relatives to powdery mildew fungi, which cause plant diseases. Unlike powdery mildews, these Arachnopeziza fungi can be easily grown in the lab and genetically modified. By studying these more manageable fungi, researchers can better understand how powdery mildew fungi became obligate parasites that must live on plants, potentially leading to better ways to control this widespread plant disease.

Sporothrix davidellisii: A new pathogenic species belonging to the Sporothrix pallida complex

mycolabadmin

Scientists have identified a new fungal species called Sporothrix davidellisii that causes an infection in cats. This fungus was found in an infected cat in Australia and is related to other fungi that cause sporotrichosis, a skin disease in humans and animals. The discovery shows that cats can help scientists identify new fungal pathogens in their environments, making them important sentinels for tracking emerging diseases.

De novo genome sequencing and comparative analyses of the clinically relevant species Mucor ardhlaengiktus, Mucor circinelloides, Mucor griseocyanus, and Mucor janssenii

mycolabadmin

Scientists have sequenced and analyzed the complete genomes of four species of Mucor fungus that cause serious infections in humans. Using advanced long-read sequencing technology, they created high-quality genetic blueprints for these organisms, which will help doctors better identify which Mucor species is causing infections and enable faster diagnosis and treatment of these dangerous fungal infections.

Unusual genome expansion and transcription suppression in ectomycorrhizal Tricholoma matsutake by insertions of transposable elements

mycolabadmin

Scientists sequenced the genome of the prized matsutake mushroom and discovered it has an unusually large genome packed with transposable elements (jumping DNA sequences). These transposable elements act like genetic ‘parasites’ that accumulate over time and actually silence many neighboring genes by preventing them from being expressed. The research shows how mushrooms evolved specialized mechanisms to control these genetic parasites while adapting to living symbiotically with pine tree roots.

Complete mitochondrial genome sequence of the Agaricomycetes brown rot fungus Fomitopsis pinicola isolate FBCC1181

mycolabadmin

Scientists have sequenced the complete mitochondrial DNA (a small genome within fungal cells) of a wood-rotting mushroom called Fomitopsis pinicola. The mitochondrial genome is 66,500 base pairs long and contains 64 genes typical for this group of fungi. The researchers discovered several special genes called endonucleases within the genome that may help the fungus adapt and change over time.

Genome resource of Phlyctema vagabunda strain 19EL15, a pathogen of post-harvest bull’s eye rot of apple

mycolabadmin

Scientists sequenced the complete genetic blueprint of a fungus called Phlyctema vagabunda that causes serious damage to apples and pears after harvest, particularly creating brown spots called bull’s eye rot. The fungus is found across Europe and North America and costs farmers significant money in crop losses. This genetic information will help researchers better understand how the fungus works and develop better ways to prevent or manage the disease.

Chromosome-Level Genome Assembly of Trichoderma cornu-damae Using Hi-C Data

mycolabadmin

Researchers created a complete genetic blueprint of a poisonous mushroom called Trichoderma cornu-damae that can be mistaken for medicinal mushrooms. Using advanced DNA sequencing techniques, they mapped all seven chromosomes and identified over 8,500 genes in this toxic fungus. This genetic map will help scientists understand how the mushroom produces dangerous toxins that harm rapidly growing cells. The work provides important information for identifying and studying this poisonous species.

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.

A high-quality genome assembly of Lactarius hatsudake strain JH5

mycolabadmin

Scientists have completed a detailed genetic blueprint of the red milk mushroom (Lactarius hatsudake), an edible and medicinal fungus that grows in pine forests. This mushroom is nutritious and has been shown to help with diabetes, boost immunity, and fight harmful bacteria. The new genetic map is much more complete and detailed than previous versions, which will help farmers grow these valuable mushrooms more reliably and sustainably, and could lead to developing better varieties.
