Orthrus: a Pumilio-family gene involved in fruiting body and dark stipe development in Coprinopsis cinerea

mycolabadmin

Scientists studied a gene called ort2 in a common lab mushroom species to understand how mushrooms develop their fruiting bodies. They found that this gene is particularly important for developing dark stipes – elongated structures that mushrooms grow in darkness to push themselves toward light. By turning this gene off or increasing its activity, researchers could control how many dark stipes formed, suggesting this gene could have practical applications in mushroom farming.

Heterologous expression of the hypovirus CHV1-EP713 full-length cDNA in Botrytis cinerea: transformation with Agrobacterium tumefaciens and evaluation of changes in the fungal phenotype

mycolabadmin

Researchers successfully introduced a virus from chestnut blight fungus into gray mold fungus to reduce its ability to cause disease. The transformed fungus grew slower, produced fewer spores, and caused less damage to plants. This discovery suggests viruses could be used as natural biological control agents to protect crops from fungal diseases.

Structural and Functional Analysis of Peptides Derived from KEX2-Processed Repeat Proteins in Agaricomycetes Using Reverse Genetics and Peptidomics

mycolabadmin

Researchers studied special peptides made by mushrooms that are processed by fungal enzymes called KEX2 and KEX1. They developed a method to find and identify these peptides in mushroom tissues and confirmed they exist in both laboratory and edible mushroom species like shiitake and oyster mushrooms. When they removed the genes for these processing enzymes, the mushrooms had problems growing and forming fruiting bodies, suggesting these enzymes have important roles beyond just processing these specific peptides.
