Novel acid trehalase belonging to glycoside hydrolase family 37 from Pleurotus sp.: cloning, expression and characterization

mycolabadmin

Scientists discovered a new enzyme in Pleurotus mushrooms that breaks down trehalose, a special sugar that mushrooms use for growth and survival. This enzyme is unusual because it works in acidic conditions and belongs to a family of enzymes (GH37) that was previously thought only to contain neutral trehalases. The researchers cloned and produced this enzyme in laboratory yeast, then tested its properties to understand how it functions. This discovery helps explain how mushrooms manage their sugar metabolism during growth and decay.

Haplotype-Phased Chromosome-Level Genome Assembly of Floccularia luteovirens Provides Insights into Its Taxonomy, Adaptive Evolution, and Biosynthetic Potential

mycolabadmin

Scientists successfully decoded the complete genetic blueprint of the yellow mushroom (Floccularia luteovirens), a valuable medicinal fungus found on the Tibetan Plateau. The high-quality genome assembly revealed the mushroom produces many different beneficial compounds like antitumor and anti-inflammatory molecules. The study also corrected previous scientific confusion about the mushroom’s evolutionary classification, showing it’s more closely related to other fungi than previously thought, and revealed how it adapted to harsh alpine conditions.

Haplotype-Phased Chromosome-Level Genome Assembly of Floccularia luteovirens Provides Insights into Its Taxonomy, Adaptive Evolution, and Biosynthetic Potential

mycolabadmin

Scientists have created the most detailed genetic map of the yellow mushroom (Floccularia luteovirens), a highly valued medicinal and edible fungus from the Tibetan Plateau. Using advanced sequencing technology, they mapped its 13 chromosomes and identified 15 pathways that the mushroom uses to make potentially useful healing compounds. The research also solved a long-standing mystery about the mushroom’s family tree, proving it is not actually related to Armillaria mushrooms as previously thought. This genetic blueprint opens new possibilities for developing medicines from this special fungus.

Saprotrophic Wood Decay Ability and Plant Cell Wall Degrading Enzyme System of the White Rot Fungus Crucibulum laeve: Secretome, Metabolome and Genome Investigations

mycolabadmin

This study investigates how a forest fungus called Crucibulum laeve breaks down wood and plant material. Using specialized laboratory techniques, researchers found that this fungus uses a unique set of enzymes that work through oxidation (chemical breakdown using oxygen) rather than simple digestion. The fungus is particularly good at degrading birch wood and produces numerous copies of genes for these special enzymes, giving it an advantage in decomposing partially rotted plant material on the forest floor.
