Holly ( L.) is a woody dioecious genus cultivated as pharmaceutical, ornamentals, and industrial materials. (H. Lév.) Loes is an endemic medicinal holly with a predominant distribution in Mount Huangshan, China. In the present work, the complete plastid genome of was sequenced by high-throughput sequencing technology. The newly-assembled plastid genome holds 37.6% of the overall GC content and a length of 157,857 bp, comprising a large single-copy (LSC, 87,255 bp), a small single-copy (SSC, 18,398 bp), and a pair of inverted repeat (IRs, 26,102 bp) regions. The plastid genome annotation suggested the presence of a total of 89 protein-encoding genes, 37 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes. The plastome-mediated phylogenetic topology revealed that clustered together with and in the same clade, and a strong relationship between clades and biogeography was found. These data contribute to the understanding of genetic diversity and conservation study of in Mount Huangshan.
冬青属（Ilex L.）是一种木本雌雄异株属植物，作为药用、观赏和工业原料进行栽培。安徽冬青（Ilex anhweiensis (H. Lév.) Loes）是一种中国特有的药用冬青，主要分布于中国黄山。在本研究中，通过高通量测序技术对安徽冬青的完整质体基因组进行了测序。新组装的质体基因组的GC含量为37.6%，长度为157,857 bp，包括一个大单拷贝（LSC, 87,255 bp）、一个小单拷贝（SSC, 18,398 bp）和一对反向重复（IRs, 26,102 bp）区域。质体基因组注释表明共存在89个蛋白质编码基因、37个转运RNA（tRNA）基因和8个核糖体RNA（rRNA）基因。质体基因组介导的系统发育拓扑结构显示，安徽冬青与榕叶冬青（Ilex ficoidea）和全缘冬青（Ilex integra）聚集在同一分支中，并且发现分支与生物地理学之间存在密切关系。这些数据有助于了解黄山安徽冬青的遗传多样性和保护研究。
