is a common cultivated species in the genus due to its elegant appearance, rich flower colors and strong fragrance, but its classification is quite controversial. In this study, the complete chloroplast genome of was obtained by Illumina sequencing. The chloroplast genome of is 150,070 bp in length with an overall GC content of 37.12%, which contains a large single-copy (LSC;84,949 bp) region, a small single-copy (SSC;13,745bp) region, and a pair of inverted repeats (IRs; 25,688 bp) regions. The genome contains 130 genes, namely 84 protein-coding genes, 38 tRNA genes and 8 rRNA genes. The maximum-likelihood phylogenetic tree has proved that should exist as an independent species in the genus , and it is most closely related to . This study provides valuable sequence resources for further study of .
由于其优雅的外观、丰富的花色和浓郁的香气，是该属中一种常见的栽培物种，但其分类颇具争议。在本研究中，通过Illumina测序获得了该物种的完整叶绿体基因组。该物种的叶绿体基因组长度为150,070 bp，总体GC含量为37.12%，包含一个大单拷贝（LSC；84,949 bp）区域、一个小单拷贝（SSC；13,745bp）区域和一对反向重复（IRs；25,688 bp）区域。该基因组包含130个基因，即84个蛋白质编码基因、38个tRNA基因和8个rRNA基因。最大似然系统发育树证明该物种应作为该属中的一个独立物种存在，并且它与关系最为密切。本研究为该物种的进一步研究提供了有价值的序列资源。
