摘要

毛茛（Ranunculus muricatus L. 1753），俗称带刺果毛茛，是一种广泛分布的药用植物。本研究首次报道了该物种完整的叶绿体基因组。基因组显示典型的四部结构，长度为155,129 bp (LSC: 84,636 bp; SSC: 18,909 bp; IRs: 25,792 bp)， GC含量为37.9%。共标注126个功能基因，其中蛋白编码基因81个，tRNA基因37个，rRNA基因8个。系统发育分析表明，在多花科中，鼠背鼠背鼠与长背鼠属一个单系群。这些发现为今后对其物种鉴定、遗传多样性和系统进化的研究提供了依据。

The complete chloroplast genome of Ranunculus muricatus L. (Ranunculaceae): insights into genome features and evolutionary relationships.

Ranunculus muricatus L. 1753, commonly known as spiny fruit buttercup, is a widely distributed medicinal plant. This study reported the first complete chloroplast genome of this species. The genome reveals a typical quadripartite structure, spanning 155,129 bp (LSC: 84,636 bp; SSC: 18,909 bp; IRs: 25,792 bp each) with 37.9% GC content. It was annotated 126 functional genes, including 81 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis showed that R. muricatus clustered a monophyletic group with R. repens within the section Polyanthemos. These findings support future research on its species identification, genetic diversity and phylogenetic evolution.
