Advancement in Mushroom Transformation: From Conventional Techniques to Modern Genetic Engineering

Mushrooms have long been valued for their nutritional, pharmaceutical, and culinary benefits. Recent studies showcased mushrooms as bio-factories for protein production, and as a source of value-added products by employing genetic manipulation and molecular transformation techniques. Advancements in molecular tools and transformation methods have enhanced the efficiency of genetic improvements in mushrooms by both conventional and modern genetic engineering techniques, paving the way for their use in various industrial applications. Genetic transformation in mushrooms involves transferring genes within and across species to understand gene functions and improve mushroom qualities. The techniques involved in transformation includes Agrobacterium-mediated transformation, hybridization, mutation breeding, particle bombardment, protoplast fusion, and CRISPR/Cas9. This review outlines the life cycle of mushrooms, major difficulties in mushroom transformation, various transformation techniques, their history, efficiency, and success rate. It also highlights the potential of genetic engineering to revolutionize mushroom cultivation and their applications.
