is one of the most popular ornamental and landscaping plants planted in tropical and subtropical regions. The brightly colored bracts, long florescence and strong stress resistance make perfect ornamental horticulture plant. plants have been frequently hybridized, resulting in more than 400 varieties. To investigate the chloroplast genome will help us to understand the biological diversity and stress resistance of plants better. Here, we report the complete chloroplast genome of which is 154,542 bp in length, including a large single copy (LSC) region of 85,695 bp and a small single copy (SSC) region of 18,077 bp, separated by a pair of identical inverted repeat regions (IRs) of 25,385 bp each. A total of 128 genes were identified, including 83 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis based on 12 chloroplast genomes showed that , accompanied with its sister species formed a base clade in Nyctaginaceae which was close to . This study will be helpful for better understanding of the genetic diversity and stress resistance of plants.
是热带和亚热带地区种植的最受欢迎的观赏和园林植物之一。其苞片颜色鲜艳、花期长且抗逆性强，是理想的观赏园艺植物。该植物经常杂交，产生了400多个品种。研究叶绿体基因组将有助于我们更好地了解该植物的生物多样性和抗逆性。在此，我们报告了该植物的完整叶绿体基因组，其长度为154,542 bp，包括一个85,695 bp的大单拷贝（LSC）区域和一个18,077 bp的小单拷贝（SSC）区域，由一对各为25,385 bp的相同反向重复区域（IRs）隔开。共鉴定出128个基因，包括83个蛋白质编码基因、37个tRNA基因和8个rRNA基因。基于12个叶绿体基因组的系统发育分析表明，该植物与其近缘物种形成了紫茉莉科中一个靠近[某物种]的基部进化枝。本研究将有助于更好地了解该植物的遗传多样性和抗逆性。
