Complete chloroplast genome of Prunus itosakura (Rosaceae), a wild flowering cherry from Japan

Abstract

Prunus itosakura is a flowering tree species with high ornamental and economic values. We determined the first complete chloroplast genome of P. itosakura using genome skimming approach. The cp genome was 157,813 bp long, with a large single-copy region (LSC) of 85,931 bp and a small single-copy region (SSC) of 19,120 bp separated by a pair of inverted repeats (IRs) of 26,381 bp. 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. itosakura is closely related with Prunus subhirtella var. subhirtella.
