The complete chloroplast genome sequence of <i>Pinus bhutanica</i> (Pinaceae) and its phylogenetic implications

<i>Pinus bhutanica</i> is a critically endangered conifer and occurs only in central Bhutan, northwestern Yunnan and southeastern Xizang in China. In this study, the complete chloroplast genome of <i>Pinus bhutanica</i> was first assembled based on next-generation sequencing. The genome sequence was 116,919 bp in length with an overall GC content of 38.75%. A total of 106 functional genes were detected in the genome, including 72 protein-coding genes (PCGs), 30 transfer RNA (tRNA) genes, and four ribosomal RNA (rRNA) genes. The phylogenetic tree reconstructed by 12 chloroplast genomes revealed that <i>P. bhutanica</i> is most closely related to <i>Pinus wangii</i> in subsection <i>Strobus</i> of <i>Pinus</i>.
