Abstract

Glochidion puberum (L.) Hutch., a member of the family Phyllanthaceae, is widely distributed in China and possesses both medicinal and ornamental value. Despite its ecological and economic significance, the complete chloroplast genome of G. puberum had not been reported, and its phylogenetic placement within the genus Glochidion has remained unresolved. In this study, we assembled and annotated the complete chloroplast genome of G. puberum for the first time. The chloroplast genome is 157,133 bp in length, exhibiting an overall GC content of 37% and containing 129 genes. The result of phylogenetic analysis revealed a close evolutionary relationship among G. puberum, G. hirsutum, and G. chodoense based on complete chloroplast genome. These findings provide comprehensive genomic data for G. puberum and offer new perspectives on the phylogenetic relationships and evolutionary position in the broader Phyllanthaceae family.

毛豆叶绿体基因组结构及系统发育的综合分析厨。

被青春期的Glochidion （L.）厨。是千余科植物，在中国广泛分布，具有药用和观赏价值。尽管其具有重要的生态和经济意义，但其完整的叶绿体基因组尚未被报道，其在Glochidion属中的系统发育定位仍未得到解决。在本研究中，我们首次组装和注释了微嫩菇的完整叶绿体基因组。叶绿体基因组长度为157,133 bp，总GC含量为37%，包含129个基因。系统发育分析结果显示，基于完整的叶绿体基因组，毛毛草、毛毛草和毛毛草具有密切的进化关系。这些发现提供了全面的基因组数据，并为更广泛的叶子科植物的系统发育关系和进化地位提供了新的视角。
