Fungal Species:  Dichomitus squalens

The Nearly Complete Genome of Grifola frondosa and Light-Induced Genes Screened Based on Transcriptomics Promote the Production of Triterpenoid Compounds

Researchers sequenced the complete genetic code of maitake mushroom (Grifola frondosa) and discovered how light exposure influences the production of beneficial compounds called triterpenoids. The high-quality genome assembly revealed 12,526 genes and showed that light triggers specific genes involved in making these medicinal compounds. This breakthrough provides a scientific foundation for growing maitake mushrooms with optimized levels of health-promoting substances.

Biological Characteristics and Domestication of Dichomitus squalens and the Antioxidant Activity of Its Cultivated Fruiting Bodies

Researchers cultivated a type of fungus called Dichomitus squalens and extracted beneficial compounds called polysaccharides from its fruiting bodies. These polysaccharides showed strong antioxidant properties, meaning they can help protect cells from damage caused by harmful free radicals. The study identified the best growing conditions for this fungus and developed methods for farming it, suggesting it could become a natural source of antioxidants for health applications.

Reintroducing threatened pine-associated fungal species in boreal forests

Researchers successfully used inoculation to introduce five rare fungal species back into protected forests in Finland. By injecting fungal cultures into pine logs, the fungi established successfully in 28-60% of logs within one year. The study shows that inoculation can be an effective tool for restoring threatened fungal species to forests, though long-term monitoring is needed to confirm these fungi will continue growing and producing fruiting bodies.

Pan-genomic characterization and structural variant analysis reveal insights into spore development and species diversity in Ganoderma

Researchers completed the first comprehensive genome study of 15 Ganoderma (Lingzhi/Reishi) varieties, including five new Chinese strains. They discovered that specific genetic changes in the MSH4 gene dramatically increase spore production in one superior strain. These findings help explain why different Ganoderma varieties have different medicinal properties and can guide breeding of better medicinal mushroom varieties.
