Characterization of the complete chloroplast genome of Peltoboykinia tellimoides (Saxifragaceae).

Peltoboykinia tellimoides, which is distributed in Japan and China, is the type species of Peltoboykinia. In this study, we sequenced and assembled the complete chloroplast (cp) genome of P. tellimoides and reconstructed the phylogeny of Saxifragaceae based on the whole cp genome sequences. The cp genome of P. tellimoides was 156,274 bp in length, comprising a pair of inverted repeat regions (25,099 bp) separated by a large single copy region (88,109 bp) and a small single copy region (17,967 bp). The genome encoded 112 unique genes consisting of 78 different protein-coding genes, 30 transfer RNA and four ribosomal RNA genes, with 16 duplicated genes in the inverted repeats. Phylogenetic analysis indicated that P. tellimoides together with three Chrysosplenium species formed a high support clade, which was sister to Micranthes melanocentra.
