In this study, we report the first complete chloroplast (cp) genome sequence of . The cp genome is 155,026 bp in length, exhibiting a typical quadripartite structure of a large single copy (LSC) region of 83,917 bp, a small single copy (SSC) region of 16,285 bp and a pair of inverted repeats (IRs) region of 27,412 bp. The overall base composition of the cp genome in asymmetric order is A: 32.09%, C: 17.94%, G: 18.65%, and T: 31.31%, and the AT content is 63.4%, whereas the proportions of AT contents in LSC, SSC, and IR regions are 66.53%, 68.99%, and 58.27%, respectively. Further, phylogenetic analysis of 46 species shows that is evolutionarily closest to , and both of them belong to the genus .
在本研究中，我们报道了……的首个完整叶绿体（cp）基因组序列。该cp基因组长度为155,026 bp，呈现出典型的四分体结构，即83,917 bp的大单拷贝（LSC）区域、16,285 bp的小单拷贝（SSC）区域和一对27,412 bp的反向重复（IR）区域。cp基因组的总体碱基组成按不对称顺序为：A：32.09%，C：17.94%，G：18.65%，T：31.31%，AT含量为63.4%，而LSC、SSC和IR区域的AT含量比例分别为66.53%、68.99%和58.27%。此外，对46个物种的系统发育分析表明，……在进化上与……最接近，且它们都属于……属。
