• To facilitate the study of gene function in edible fungi using genetic engineering.

Main Methods:

• Integration of target gene fragments into vectors for transformation.
• Construction of specialized vectors (silencing, knockout, overexpression) using promoters, marker genes, and reporter genes.
• Application of various transformation methods including Agrobacterium-mediated transformation, liposome transformation, and electroporation.

Main Results:

• Demonstrated the utility of molecular biology and genetic engineering for targeted gene modification in edible fungi.
• Highlighted the importance of specific plasmids (pCAMBIA-1300, pAN7) as foundational vectors.
• Showcased the successful construction of diverse expression vector systems tailored for different transformation approaches.

Conclusions:

• Genetic engineering offers powerful strategies for elucidating edible fungi gene function.
• The choice of vector system and transformation method is critical for successful gene manipulation.
