In this study, we determined the complete plastome sequence of (Kunth) Baehni (Sapotaceae) (NCBI acc. no. KX426215). This is the first time a plastome from the Sapotaceae has been sequenced. The gene order and structure of the plastome are collinear with those of the typical plastome of land plants. The complete plastome size is 157,922 bp in length and consists of a large single-copy region of 87,122 bp and a small single-copy region of 18,559 bp, which are separated by a pair of 26,120 bp-long inverted repeat regions. The overall A-T content of the plastome sequence is 63.2%. The plastome contains 113 genes, of which 79 are protein-coding genes, 30 are tRNA genes, and 4 are rRNA genes. Sixteen genes contain one intron and two genes have two introns. A total of 91 simple sequence repeat loci were identified within the genome. Phylogenetic analysis revealed that is a sister group of the Primulaceae-Ebenaceae clade with 100% bootstrap support.
在本研究中，我们测定了（Kunth）Baehni（山榄科）的完整质体基因组序列（NCBI登录号：KX426215）。这是首次对山榄科植物的质体基因组进行测序。该质体基因组的基因顺序和结构与陆地植物典型质体基因组的基因顺序和结构共线。完整的质体基因组长度为157,922 bp，由一个87,122 bp的大单拷贝区域和一个18,559 bp的小单拷贝区域组成，这两个区域被一对长度为26,120 bp的反向重复区域隔开。质体基因组序列的总体A - T含量为63.2%。该质体基因组包含113个基因，其中79个是蛋白质编码基因，30个是tRNA基因，4个是rRNA基因。16个基因含有一个内含子，2个基因含有两个内含子。在基因组内共鉴定出91个简单序列重复位点。系统发育分析表明，该植物是报春花科 - 柿树科分支的姐妹群，自展支持率为100%。
