Cheng ex Yü, a small excellent ornamental tree species, is only distributed in Eastern China. In this study, we assembled and annotated the complete chloroplast (cp) genome of the species using the next-generation sequencing for the first time. The cp genome was 160,006 bp in size, consisting of two copies of invert repeat (IR) regions of 26,405 bp, one large single-copy (LSC) region of 87,870bp, and one small single-copy (SSC) region of 19,326 bp. The overall GC content of the genome was 36.55%. The genome was predicted to contain 128 genes, including 88 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis of 25 chloroplast genomes in Rosaceae indicated that . is most closely related to . . These findings may provide useful information to the phylogeny of the genus .
俞氏海棠，一种优良的小型观赏树种，仅分布于中国东部。在本研究中，我们首次使用二代测序技术组装并注释了该物种的完整叶绿体基因组。叶绿体基因组大小为160,006 bp，由两个26,405 bp的反向重复（IR）区域、一个87,870 bp的大单拷贝（LSC）区域和一个19,326 bp的小单拷贝（SSC）区域组成。基因组的总体GC含量为36.55%。该基因组预计包含128个基因，包括88个蛋白质编码基因、37个tRNA基因和8个rRNA基因。蔷薇科25个叶绿体基因组的系统发育分析表明，俞氏海棠与[具体物种1]关系最为密切。这些发现可能为[具体属]的系统发育提供有用信息。
