Abstract

Buxus sinica var. parvifolia is a shrub or small arbor of the Buxaceae family, rich in various medicinal alkaloids and of great horticultural value. In this study, we sequenced, assembled, and annotated the complete chloroplast genome of B. sinica var. parvifolia for the first time. The length of the chloroplast genome is 158,995 bp with 38.1% overall GC content. It includes a large single-copy (LSC) region of 88,140 bp, a small single-copy (SSC) region of 17,761 bp, and two inverted repeat regions of 26,547 bp. Additionally, 132 functional genes in the genome are identified, including 87 protein-coding genes, eight ribosomal RNA genes, and 37 transfer RNA genes. Phylogenetic analysis showed that B. sinica var. parvifolia is closely related to Buxus microphylla. The complete chloroplast genome sequence of B. sinica var. parvifolia and its phylogenetic analysis provides useful genomic information for the further study of B. sinica var. parvifolia and other Buxus species.

茜草科植物茜草的完整叶绿体基因组及其系统发育分析。

银杏（Buxus sinica var. parvifolia）是一种灌木或小乔木，属杨梅科，富含多种药用生物碱，具有重要的园艺价值。在这项研究中，我们首次对洋金花的叶绿体基因组进行了测序、组装和注释。叶绿体基因组长度为 158,995 bp，总 GC 含量为 38.1%。它包括一个大的单拷贝（LSC）区（88,140 bp）、一个小的单拷贝（SSC）区（17,761 bp）和两个倒置重复区（26,547 bp）。此外，基因组中还发现了 132 个功能基因，包括 87 个蛋白质编码基因、8 个核糖体 RNA 基因和 37 个转运 RNA 基因。系统进化分析表明，B. sinica var.B. sinica var. parvifolia 的完整叶绿体基因组序列及其系统进化分析为进一步研究 B. sinica var.
