Abstract

Pinus tabuliformis var. henryi (Mast.) C.T.Kuan 1983 is an endemic and rare subtropical pine, mainly distributed in central China. In this study, we sequenced the complete chloroplast (cp) genome of P. tabuliformis var. henryi and reported it for the first time. The cp genome was 119,634 base pairs (bp) in total length, including two inverted repeats (IRs, 495 bp), separated by a large single-copy region (LSC, 65,600 bp) and a small single-copy region (SSC, 53,044 bp). There are 114 different genes in the cp genome of P. tabuliformis var. henryi, including 74 protein-coding genes, 36 transfer RNA genes, and four ribosomal RNA genes. The overall GC content of the cp genome was 38.5%. Our phylogenetic analysis of P. tabuliformis var. henryi demonstrated that it was closely related to P. tabuliformis and could be used to identify and analyze its genetic diversity, which was expected to provide new data for taxonomic and phylogenetic studies of Pinus.
