The complete chloroplast genome of Prinsepia uniflora (Rosaceae), a medicinal plant found in northwest China

Prinsepia uniflora Batalin 1892 is a medicinal plant widely distributed in northwest China. In this study, we report and characterize the complete chloroplast (cp) genome sequence of P. uniflora. The entire sequence is 159,179 bp in length, consisting of the large single-copy region (LSC) and small single copy region (SSC) (87,239 and 19,180 bp, respectively); these two regions are separated by a pair of 26,380-bp inverted repeat (IR) regions. The genome contains 131 genes, including 86 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall GC content of the genome is 36.7%. A phylogenetic tree constructed from 18 chloroplast genomes revealed that P. uniflora was clustered with Prinsepia sinensis and Prinsepia utilis, all of which belong to the genus Prinsepia, which is supported as a sister group by a moderate bootstrap support value of 55% with the Malus and Pyrus genera.
