On site discrimination between two closely related commercial strains of oyster mushroom using a loop-mediated isothermal amplification (LAMP) test

mycolabadmin

Scientists developed a quick molecular test to identify two specific commercial oyster mushroom strains (SPOPPO and ALLERPO) in less than 30 minutes using a technique called LAMP. These sporeless mushroom strains were created to reduce respiratory health problems that workers develop from inhaling mushroom spores. The new test helps mushroom producers and breeders quickly verify strain identity in the field to prevent unauthorized copying of these valuable varieties and to catch products of suspect origin.

Novel and advanced MNP molecular markers accurately identify the genetic similarity of Hypsizygus marmoreus strains: a comparative evaluation with ISSR and antagonistic methods

mycolabadmin

Scientists developed a new DNA-based method to accurately identify different strains of king oyster mushrooms (Hypsizygus marmoreus). Using advanced genetic analysis on 32 mushroom varieties, they created a database of 369 genetic markers that can distinguish between strains with high accuracy. This new method is faster and more reliable than traditional testing methods, helping mushroom farmers and breeders maintain quality and prevent confusion between similar-looking varieties.

On site discrimination between two closely related commercial strains of oyster mushroom using a loop-mediated isothermal amplification (LAMP) test

mycolabadmin

Scientists developed a quick test to identify two specific types of oyster mushrooms (SPOPPO and ALLERPO) on farms or spawn production facilities. These sporeless mushroom varieties were created to protect workers from respiratory problems caused by mushroom spores. The new LAMP test can identify which strain is being grown in just 30 minutes using simple sample preparation, helping protect the breeding companies’ intellectual property rights from illegal copying.

Genetic Clarification of Auricularia heimuer Strains Bred and Cultivated in Korea Using the ITS and IGS1 rDNA Region Sequences

mycolabadmin

Researchers in Korea discovered that Auricularia mushrooms grown there are actually a different species than previously thought. By analyzing the genetic code of different mushroom strains, scientists confirmed they are all the species A. heimuer rather than A. auricula-judae. They also found that using specific genetic markers (IGS1 sequences) could tell apart different mushroom varieties and identify which strains were produced through breeding.

High-Resolution Core Gene-Associated Multiple Nucleotide Polymorphism (cgMNP) Markers for Strain Identification in the Wine Cap Mushroom Stropharia rugosoannulata

mycolabadmin

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.
