We focus on current advances in protoplast regeneration, symmetric and asymmetric hybridization, and unique technological innovations in this review. New species regeneration and enhanced cultivation techniques have brought up new possibilities for practical breeding in a variety of crops. It is examined the significance of protoplast sources and embedding systems. The investigation of reactive oxygen species and DNA (de)condensation, as well as detailed phytohormone monitoring, are the most promising research subjects in the ongoing quest for protoplast regeneration rationalization, in our opinion. The next section summarizes the progress of fusion and fragmentation. Fundamental processes such as cell wall production, cell growth, and chromosome rearrangements in fusion products, whether or not acquired following irradiation, have benefited from genomic, transcriptomic, and proteomic investigations. Advanced genome and cytoplasm molecular screening technologies allow for efficient screening of both symmetric and asymmetric fusion products. Emerging technologies such as GISH, high-resolution melting, and next-generation sequencing are expected to make significant advances to our understanding of genome formation and stabilization, particularly following asymmetric hybridization. Finally, we show that somatic hybridization has agricultural value by enumerating recent trait introgression in a variety of commercial crops.We focus on current advances in protoplast regeneration, symmetric and asymmetric hybridization, and unique technological innovations in this review.
