D. belongs to the Sapotaceae family, which is an evergreen shrub native to tropical West Africa. It is a kind of magical plant that has the unique characteristic of modifying sour flavors to sweet. In this study, the chloroplast genome of was sequenced, assembled, and annotated firstly. Chloroplast genome size of is 158,463 bp, the circular chloroplast genome consists of four regions: a large single-copy region of 88,256 bp, two inverted repeat regions of 25,958 bp, and a small single-copy region of 18,669 bp, with the GC content of 36.87%. A total of 133 genes were annotated in the chloroplast genome, of which 88 were protein-coding genes (PCGs), 37 were transfer RNA (tRNA) genes, and eight were ribosomal RNA (rRNA) genes. Phylogenetic analysis showed that was most closely related to . The study provides important genomic data for further utilization and breeding of .
D.属于山榄科，是一种原产于热带西非的常绿灌木。它是一种神奇的植物，具有将酸味转化为甜味的独特特性。在本研究中，首先对D.的叶绿体基因组进行了测序、组装和注释。D.的叶绿体基因组大小为158,463 bp，环状叶绿体基因组由四个区域组成：一个88,256 bp的大单拷贝区域、两个25,958 bp的反向重复区域和一个18,669 bp的小单拷贝区域，GC含量为36.87%。在D.的叶绿体基因组中总共注释了133个基因，其中88个是蛋白质编码基因（PCG），37个是转运RNA（tRNA）基因，8个是核糖体RNA（rRNA）基因。系统发育分析表明D.与[具体物种名称未给出]关系最为密切。该研究为D.的进一步利用和育种提供了重要的基因组数据。
