Complete chloroplast genome of Prunus rufa (Rosaceae), a wild flowering cherry endemic to the Himalayan region

Abstract

Prunus rufa is a species of Prunus native to the Himalayan region. We determined the first complete chloroplast genome of P. rufa using a genome skimming approach. The cp genome was 157,723 bp long, with a large single-copy region (LSC) of 85,860 bp and a small single-copy region (SSC) of 19,081 bp separated by a pair of inverted repeats (IRs) of 26,391 bp each. It encodes 129 genes, including 84 protein-coding genes, 37 tRNA genes, and 8 ribosomal RNA genes. We also reconstructed the phylogeny of Prunus sensu lato using maximum-likelihood (ML) method, including our data and previously reported cp genomes of related taxa. The phylogenetic analysis indicated that P. rufa is closely related to Prunus cerasoides.
