S.S.Chang is an evergreen plant of from the family Moraceae. This is an endangered species endemic to China. In terms of economic value, are used as a native plant resource of urban landscaping in Chongqing, China. Here, we sequenced, assembled and annotated the chloroplast (cp) genome of , and aim to provide genetic resources for this endangered species. The length of cp genome was 160,595 bp, with a large single-copy region (LSC) of 88,683 bp and a small single-copy region (SSC) of 20,160 bp separated by a pair of inverted repeats (IRs) of 25,876 bp. It encodes 110 unique genes, including 76 protein-coding genes, 30 transfer RNA genes, and 4 ribosomal RNA genes. Besides, we reconstructed the phylogeny of Moraceae based on the whole cp genome sequences data set. Phylogenetic analysis shows that all analyzed species are clustered and form a monophyletic group. is a sister group to . In our maximum likelihood (ML) tree, is closely related to .
S.S.Chang是桑科的一种常绿植物。这是中国特有的濒危物种。在经济价值方面，在中国重庆被用作城市园林绿化的本土植物资源。在此，我们对其叶绿体（cp）基因组进行了测序、组装和注释，旨在为这种濒危物种提供遗传资源。cp基因组长度为160,595bp，有一个88,683bp的大单拷贝区域（LSC）和一个20,160bp的小单拷贝区域（SSC），由一对25,876bp的反向重复序列（IRs）隔开。它编码110个独特基因，包括76个蛋白质编码基因、30个转运RNA基因和4个核糖体RNA基因。此外，我们基于整个cp基因组序列数据集重建了桑科的系统发育。系统发育分析表明，所有分析的物种都聚类形成一个单系类群。S.S.Chang是与[某物种]的姐妹群。在我们的最大似然（ML）树中，S.S.Chang与[某物种]密切相关。
