var. (Aug. Candolle) Dandy is a timber and spices species in Magnoliaceae, native to China and Vietnam. In this paper, the complete chloroplast genome (cpDNA) and basic annotated information were reported and its phylogenetic relationship with other species in Magnoliaceae was analyzed. The size of chloroplast genome of var. is 160,134 bp, which exhibited a typical quadripartite structure comprising a large single-copy (LSC) region of 88,161 bp and a small single-copy (SSC) region of 18,845 bp separated by a pair identical inverted repeat regions (IRs) of 26,564 bp each. The chloroplast genome contains 131 genes, including 86 protein-coding genes (PCGs), 37 transfer RNA (tRNA) genes and 8 ribosomal RNA (rRNA) genes. The phylogenetic analysis indicated that var. is most affinal to and they form a nomophyletic group with other 14 species. This clade is sister to the clade with high support. All genera mentioned in this analysis are nomophyletic under the system of Magnoliaceae by Sima and Lu.
var. (奥古斯特·德堪多)丹迪是木兰科的一种木材和香料植物,原产于中国和越南。本文报道了其完整的叶绿体基因组(cpDNA)及基本注释信息,并分析了它与木兰科其他物种的系统发育关系。var. 的叶绿体基因组大小为160,134 bp,呈现典型的四分体结构,包括一个88,161 bp的大单拷贝(LSC)区域和一个18,845 bp的小单拷贝(SSC)区域,由两个各为26,564 bp的相同反向重复区域(IRs)隔开。叶绿体基因组包含131个基因,其中包括86个蛋白质编码基因(PCGs)、37个转运RNA(tRNA)基因和8个核糖体RNA(rRNA)基因。系统发育分析表明,var. 与 关系最为密切,它们与其他14个 物种形成一个单系类群。这个类群是与 类群关系密切且支持率高的姊妹类群。本分析中提到的所有属在司马和卢的木兰科系统下都是单系的。
