Abstract:
Pinus kesiya var. langbianensis is an important oleoresin resource tree species in Yunnan province, China. In this study, the complete chloroplast genome (cpDNA) sequence of P. kesiya var. langbianensis was determined from Illumina HiSeq pair-end sequencing data. The cpDNA is 119,780 bp in length, contains a large single copy region (LSC) of 65,863 bp and a small single copy region (SSC) of 53,117 bp, which were separated by a pair of inverted repeat (IR) regions of 400 bp. The genome contains 113 genes, including 73 protein-coding genes, 4 ribosomal RNA genes, and 36 transfer RNA genes. The overall GC content of the whole genome is 38.5%, and the corresponding values of the LSC, SSC, and IR regions are 37.9, 39.4, and 35.5%, respectively. Further phylogenomic analysis showed that P. kesiya var. langbianensis clustered together with Pinus kesiya, Pinus densata, and Pinus taiwanensis.
