Chromosome-level assembly of Prunus serrula Franch genome.

P. serrula is widely distributed in Yunnan, Xizang, and Sichuan, and usually grows at high altitudes between 2,600 and 3,900 meters above sea level. In this study, we obtained a high-quality chromosome-level assembly genome of P. serrula using Illumina sequencing, Oxford Nanopore ultra-long sequencing, and Hi-C technology. The genome was 284.5 Mb in length, with a scaffold N50 of 32.4 Mb and 91.9% of the assembly anchored onto 8 pseudochromosomes. BUSCO completeness value of 98.5% demonstrated a high completed genome, and a total of 35,151 protein-coding genes and 47,340 transcripts were annotated. Overall, this genome delivers valuable genetic resources for further phylogenomic studies and provides insights into the genetic architectures underlying high-altitude adaptation.
