Genome-wide identification analysis in wild-type reveals some genes defending against .

exhibits strong resistance to late blight caused by but only an incomplete genome assembly based on short Illumina reads has been published. In this study, we generated the first chromosome-level draft genome for the wild-type potato species in China using Oxford Nanopore technology sequencing and Hi-C technology. The high-quality assembled genome size is 664 Mb with a scaffold N50 value of 49.17 Mb, of which 65.87% was occupied by repetitive sequences, and predominant long terminal repeats (42.51% of the entire genome). The genome of was predicted to contain 34,245 genes, of which 99.34% were functionally annotated. Moreover, 303 NBS-coding disease resistance (R) genes were predicted in the genome to investigate the potential mechanisms of resistance to late blight disease. The high-quality chromosome-level reference genome of is expected to provide potential valuable resources for intensively and effectively investigating molecular breeding and genetic research in the future.
