Thunb. is an ornamental species in the genus (Rosaceae) mainly distributed in eastern China. It is often cultivated in gardens, roadsides, or shrub clusters. It looks like a cherry but resembles to prunes as well. We obtained the complete chloroplast genome of using next-generation sequencing technology. The chloroplast genome is 158.078 bp in length with typical tetrad structure. It includes two copies of inverted repeats (IRs, 26.385 bp), a large single copy (LSC, 86.269 bp) and a small single copy (SSC, 19.039 bp). The total GC content is 36.7%, including 85 protein-coding genes (PCGs), 36 transfer genes (tRNA), and eight ribosomal genes (rRNA). The maximum-likelihood phylogeny using the full length of chloroplast genomes indicates that is closer to prunes than to cherries.
郁李是蔷薇科（Rosaceae）李属的一种观赏植物，主要分布于中国东部。它常被种植于花园、路边或灌木丛中。它看起来像樱桃，但也类似李子。我们使用下一代测序技术获得了郁李的完整叶绿体基因组。叶绿体基因组长度为158,078 bp，具有典型的四分体结构。它包括两个反向重复序列（IRs，26,385 bp）、一个大单拷贝（LSC，86,269 bp）和一个小单拷贝（SSC，19,039 bp）。总GC含量为36.7%，包括85个蛋白质编码基因（PCGs）、36个转运RNA基因（tRNA）和8个核糖体RNA基因（rRNA）。使用叶绿体基因组全长构建的最大似然系统发育树表明，郁李与李子的亲缘关系比与樱桃更近。
