Overview: 
Plums are one of the most economically important Rosaceae fruit crops and are produced throughout the world. Prunus salicina is an important diploid (2x=2n=16) plum species that predominates in the modern commercial production of plums. However, the genomic information for P. salicina as well as most plum species is scarce. Here we present a chromosome-level genome assembly of P. salicina with the combination of PacBio sequencing, Illumina Sequencing and Hi-C technology. The assembly has a total size of 284.2 Mb, with contig N50 of 1.8Mb and scaffold N50 of 32.3Mb. 96.56% of the P. salicina assembled sequences were anchored onto 8 pseudochromosomes. De novo, homology-based, and RNA-seq methods were used together to predict were used together to predict 24,448 protein-coding genes, 97.90% of which were functionally annotated. BUSCO analysis showed 95.7% complete genes. CEGMA assessment showed that our assembly captured 234 (94.35%) of the 248 ultra-conserved core eukaryotic genes, of which 229 (92.34%) were complete.
