Handel-Mazzetti is a rare tree, distinct member of the family Styracaceae. In this study, we determined the complete chloroplast (cp) genome sequence of in an effort to provide genomic resources useful for promoting its conservation. The entire cp genome was determined to be 157,165 bp in length. It contains the typical structure and gene content of angiosperm plastome, The plastome contains a large single-copy (LSC) and a small single-copy (SSC) regions of 90,193 and 18,486 bp, respectively, which were separated by a pair of 24,243 bp inverted repeat (IR) regions. The genome contained 130 genes, including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The GC content of genome is 37.21%. The complete plastome sequence of will provide a useful resource for the conservation genetics of this species as well as for the phylogenetic studies for Styracaceae. Phylogenetic analysis revealed that is closely related to H.S.Lo & D.Fang, but forms an independent evolutionary branch.
Handel-Mazzetti是一种珍稀树木,安息香科的独特成员。在本研究中,我们测定了其完整的叶绿体(cp)基因组序列,以期提供有助于促进其保护的基因组资源。整个cp基因组长度确定为157,165 bp。它具有被子植物质体基因组的典型结构和基因组成,该质体基因组包含一个90,193 bp的大单拷贝(LSC)区域和一个18,486 bp的小单拷贝(SSC)区域,它们被一对24,243 bp的反向重复(IR)区域隔开。该基因组包含130个基因,包括85个蛋白质编码基因、37个tRNA基因和8个rRNA基因。其基因组的GC含量为37.21%。该物种完整的质体基因组序列将为该物种的保护遗传学以及安息香科的系统发育研究提供有用资源。系统发育分析表明,它与H.S.Lo & D.Fang密切相关,但形成一个独立的进化分支。
