Recent developments of tools for genome and metabolome studies in basidiomycete fungi and their application to natural product research

mycolabadmin

Mushrooms and related fungi in the basidiomycete group produce many useful medicines and agricultural chemicals. Scientists have traditionally struggled to study these fungi because they grow slowly and have complex genomes. Recent technological breakthroughs—including faster DNA sequencing and gene-editing tools—are now making it much easier to discover and understand the helpful compounds these fungi produce, potentially leading to new medicines.

Molecular networking identifies an AHR-modulating benzothiazole from white button mushrooms (Agaricus bisporus)

mycolabadmin

Researchers discovered a new compound in white button mushrooms called 2-amino-4-methylbenzothiazole that activates the aryl hydrocarbon receptor, which helps regulate gut health and immunity. Using a computational approach called molecular networking to compare mushroom compounds with known beneficial substances, scientists identified this previously unknown compound and confirmed its activity in laboratory cells. This discovery demonstrates how certain mushrooms may contribute to health through specific bioactive compounds and provides a faster method for finding similar compounds in other foods.

Olive mill solid waste induces beneficial mushroom-specialized metabolite diversity revealed by computational metabolomics strategies

Researchers studied how adding olive mill waste to mushroom growing substrate affects the beneficial compounds in two edible mushrooms. They used advanced computer analysis of chemical data to find that this waste product increases healthy compounds like hericenones while reducing potentially harmful mycotoxins. This discovery could help make mushroom farming more sustainable and produce safer, healthier mushrooms for consumers.

Miniaturized high-throughput conversion of fungal strain collections into chemically characterized extract libraries for antimicrobial discovery

Scientists developed a fast, automated method called FLECS-96 to screen hundreds of fungal species for antimicrobial compounds in a small 96-well plate format. The method combines fungal culture, chemical extraction, and analysis to identify promising candidates against resistant bacteria like Staphylococcus aureus. The team successfully identified two bioactive compounds from the fungi tested. This innovation could significantly speed up the discovery of new antibiotics to combat antibiotic-resistant infections.

The endophytic fungus Cosmosporella sp. VM-42 from Vinca minor is a source of bioactive compounds with potent activity against drug-resistant bacteria

mycolabadmin

Scientists discovered a fungus living inside a medicinal plant called Vinca minor that produces compounds capable of killing drug-resistant bacteria like MRSA. They isolated the main active compound, nectriapyrone, and found it effectively stops the growth of these dangerous bacteria in laboratory tests. The fungus appears to be a promising source of new antibacterial drugs that could help combat the growing problem of antibiotic-resistant infections.

Chemical clues to infection: A pilot study on the differential secondary metabolite production during the life cycle of selected Cordyceps species

mycolabadmin

This study examined two types of parasitic fungi (Cordyceps javanica and Cordyceps blackwelliae) that infect insects, comparing how they kill their hosts and what chemical compounds they produce during infection. Researchers found that each species uses different toxic molecules to infect insects, with C. javanica being more deadly and producing diverse compounds called beauveriolides. By analyzing infected insect corpses, scientists provided the first direct evidence that these toxic compounds are actually made during real infections, not just in laboratory cultures.

Discovery of the antifungal compound ilicicolin K through genetic activation of the ilicicolin biosynthetic pathway in Trichoderma reesei

mycolabadmin

Scientists used genetic engineering to activate a dormant gene cluster in the fungus Trichoderma reesei, enabling it to produce the antifungal compound ilicicolin H in high quantities. During this process, they discovered a new related compound called ilicicolin K that shows even stronger antifungal properties. These compounds could potentially overcome limitations of current antifungal treatments, especially against drug-resistant fungi like Candida auris.

Genome-Mining Based Discovery of Pyrrolomycin K and L from the Termite-Associated Micromonospora sp. RB23

mycolabadmin

Scientists discovered two new antimicrobial compounds called pyrrolomycins from bacteria living in termites using genome sequencing and chemical analysis. These compounds contain chlorine atoms and are related to known antibiotics. The research shows how the bacteria protects itself from its own antimicrobial compounds through chemical modifications, offering insights into developing new antibiotics.

Marine-derived Acremonium strain prioritization using untargeted metabolomics approach for the identification of cytotoxic cyclic depsipeptides

mycolabadmin

Researchers studied six fungal strains from Arctic driftwood to find cancer-fighting compounds. Using advanced chemical analysis methods, they identified one strain that was particularly good at killing cancer cells in the lab. From this strain, they isolated five related compounds called depsipeptides that showed strong activity against multiple types of cancer cells. This discovery highlights how fungi from extreme environments like the Arctic could be valuable sources for developing new cancer treatments.
