Application of CRISPR/Cas9 gene editing technology in edible fungi: a review

Abstract:

The CRISPR/Cas9 gene editing system is a versatile technology for modifying gene, playing a crucial role in the study of functional genes and genetic breeding of plants, animals, fungi, and microorganisms. This review provides a comprehensive analysis of the application of this technology in gene research and genetic breeding of edible fungi. The review covers various aspects, including the delivery and expression strategies of Cas9 and sgRNA, genetic transformation methods, mutant screening, and repair strategies for target sites following DNA double-strand breaks. Additionally, the review summarizes the main challenges and optimization strategies associated with the application of this technology in edible fungi. Lastly, the future application potential of this technology in edible fungi research is discussed, drawing from the authors’ personal research background.
