and are two evergreen trees of the genus in the family Hamamelidaceae. In this study, the complete chloroplast genomes of and were sequenced, assembled, and annotated. The total lengths of the chloroplast genomes were 160,723 bp and 160,744 bp, respectively, and both had a GC content of 38.1%. The complete chloroplast genomes of these two species had typical quadripartite structures: LSC region (88,972 bp and 88,989 bp), SSC region (18,907 bp and 18,911 bp) and a pair of inverted repeats both of 26,422 bp. Both species contained 114 unique genes, including 80 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Phylogenetic analysis indicated that and are sister species to each other. Our results provide useful genetic resources for further studies on the origin and evolution of Hamamelidaceae.
[物种名称1]和[物种名称2]是金缕梅科[属名]属的两种常绿乔木。在本研究中，对[物种名称1]和[物种名称2]的完整叶绿体基因组进行了测序、组装和注释。叶绿体基因组的总长度分别为160,723 bp和160,744 bp，两者的GC含量均为38.1%。这两个物种的完整叶绿体基因组具有典型的四分体结构：大单拷贝区（LSC区，分别为88,972 bp和88,989 bp）、小单拷贝区（SSC区，分别为18,907 bp和18,911 bp）以及一对均为26,422 bp的反向重复序列。两个物种均包含114个独特基因，包括80个蛋白质编码基因、30个tRNA基因和4个rRNA基因。系统发育分析表明，[物种名称1]和[物种名称2]互为姐妹物种。我们的结果为金缕梅科起源和进化的进一步研究提供了有用的遗传资源。
