High-Resolution Core Gene-Associated Multiple Nucleotide Polymorphism (cgMNP) Markers for Strain Identification in the Wine Cap Mushroom Stropharia rugosoannulata
Scientists developed a new genetic tool called cgMNP markers to accurately identify different strains of wine cap mushrooms (Stropharia rugosoannulata). By analyzing the DNA of 105 mushroom strains collected from across China, they discovered that a single gene containing 865 genetic variations was sufficient to distinguish between all cultivated varieties. This breakthrough provides a practical way for mushroom farmers and researchers to identify specific strains quickly, which is important for breeding better mushrooms and maintaining quality in commercial production.
