var. is an endangered tree with considerable economic potential that used as timber wood for furniture and house construction. However, the natural population of var. is very fragmented, which is the cause for its low genetic diversity. In this study, we report the complete chloroplast genome of var. using Illumina sequencing. The chloroplast genome size is 117,670 bp in length, harboring a pair of very short inverted repeats (IRs) of 262 bp separated by a large single copy (LSC) sequence of 64,634 bp and a small single copy (SSC) sequence of 53,078 bp. The chloroplast genome var. contains 113 genes (74 protein genes, 35 tRNA genes, and 4 rRNA genes) and the overall GC content is 38.6%. The maximum likelihood phylogenetic analysis shows that var. is clustered with in genus . This complete chloroplast genome will help us to understand the evolution of var. and lays the foundations for future studies in this species conservation.
变种是一种具有相当大经济潜力的濒危树木，用作家具和房屋建筑的木材。然而，变种的自然种群非常分散，这是其遗传多样性低的原因。在本研究中，我们使用Illumina测序报告了变种的完整叶绿体基因组。叶绿体基因组长度为117,670 bp，包含一对262 bp的非常短的反向重复序列（IRs），由64,634 bp的大单拷贝（LSC）序列和53,078 bp的小单拷贝（SSC）序列隔开。变种的叶绿体基因组包含113个基因（74个蛋白质基因、35个tRNA基因和4个rRNA基因），总体GC含量为38.6%。最大似然系统发育分析表明，变种与属中的聚在一起。这个完整的叶绿体基因组将有助于我们了解变种的进化，并为该物种保护的未来研究奠定基础。
