The complete plastid genome (plastome) of Pentactina rupicola Nakai, the sole member of genus Pentactina, endemic to Korea, was determined in this study. The plastome of P. rupicola is 156,612 bp in length and is composed of a pair of 26,351 bp inverted repeat regions (IRa and IRb) separating large (LSC) and small (SSC) single-copy regions of 84,970 and 18,940 bp, respectively (NCBI acc. no. NC 016921). The plastome encodes 129 genes, of which 112 are unique, including 78 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Seventeen genes contain one intron and the ycf3 gene has two introns. The second intron of clpP is absent in the P. rupicola plastome. The AT content of P. rupicola is 63% overall, and in the LSC, SSC, and IR regions is 65%, 69%, and 58%, respectively. A total of 63 simple sequence repeats (SSR) are distributed among the noncoding regions of the genome. Phylogenetic analysis of the combined 82-gene data set for 35 plastomes suggests that P. rupicola is sister to the Pyrusmalus clade.
