Ilex × Koehneana 'Wirt L. Winn', an important ornamental tree, has been widely distributed in southeastern China. In this study, we assembled and characterized the complete chloroplast (cp) genome of I. Koehneana to investigate its phylogenetic relationship. The whole cp genome of I. Koehneana is 157,538 bp, which contained a large single-copy (LSC) region of 87,055 bp and a small single-copy (SSC) region of 18,429 bp, and a pair of inverted repeats (IR) of 52,054 bp. A total of 137 genes, including 90 protein-coding genes, eight rRNAs, and 39 tRNAs, were identified. Phylogenetic analysis based on 74 conserved protein-coding genes revealed that I. Koehneana is closely related to I. 'tall boy'.
冬青杂交种‘Wirt L. Winn’是一种重要的观赏树木，已在中国东南部广泛分布。在本研究中，我们组装并鉴定了冬青的完整叶绿体（cp）基因组，以研究其系统发育关系。冬青的整个cp基因组为157,538 bp，其中包含一个87,055 bp的大单拷贝（LSC）区域、一个18,429 bp的小单拷贝（SSC）区域和一对52,054 bp的反向重复序列（IR）。共鉴定出137个基因，包括90个蛋白质编码基因、8个rRNA和39个tRNA。基于74个保守蛋白质编码基因的系统发育分析表明，冬青与‘tall boy’冬青关系密切。
