The Transformation and Protein Expression of the Edible Mushroom Stropharia rugosoannulata Protoplasts by Agrobacterium-tumefaciens-Mediated Transformation

mycolabadmin

Scientists developed a genetic engineering technique to modify king stropharia (a cultivated edible mushroom) by inserting foreign genes into its cells. This breakthrough allows researchers to study how the mushroom grows and produces beneficial compounds. The technique uses a bacterium called Agrobacterium tumefaciens to naturally deliver genes into mushroom cells, similar to how it infects plants. This advancement could lead to improved cultivation practices and enhanced nutritional or medicinal properties.

Co-transformation of Aspergillus fumigatus: a simple and efficient strategy for gene editing without linking selectable markers

mycolabadmin

Scientists have developed a new technique for editing genes in a dangerous fungal pathogen called Aspergillus fumigatus. Instead of permanently attaching antibiotic resistance markers to the target genes (which can interfere with normal gene function), they use a clever strategy of introducing two different DNA pieces simultaneously. One piece makes the desired gene edit while the second introduces a resistance marker to a completely different location in the genome. This approach is simple, inexpensive, and works about 11% of the time, making it practical for identifying successfully edited strains.
