Genome editing is highly useful for crop improvement. The method of expressing genome-editing enzymes using a transient expression system in , called agrobacterial mutagenesis, is a shortcut used in genome-editing technology to improve elite varieties of vegetatively propagated crops, including potato. However, with this method, edited individuals cannot be selected.

The isolation of disease resistance genes introduced from wild or related cultivated species is essential for understanding their mechanisms, spectrum and risk of breakdown. To identify target genes not included in reference genomes, genomic sequences with the target locus must be reconstructed. However, assembly approaches of the entire genome, such as those used for constructing reference genomes, are complicated in higher plants.

Background: Tetrad sterility in potato is caused by a specific cytoplasm, called TSC, derived from the Mexican wild tetraploid species Solanum stoloniferum. Different S. stoloniferum accessions crossed as females with S.
