Wall. ex Royle, a species within the family Ranunculaceae, is mainly distributed along forest margins and grassy slopes at altitudes 2700-4000 m on the Qinghai-Tibetan Plateau. Despite its wide distribution in alpine ecosystems, its genetic diversity remains poorly understood. In this study, we assembled and characterized the complete chloroplast genome of , addressing a significant gap in our understanding of its genetic composition. The chloroplast genome is 155,864 base pairs long and contains 131 genes, including 86 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis of 15 representative species revealed that the genus can be classified into three clades. along with another nine other species formed the largest monophyletic clade and is most closely related to and . These findings enhance our understanding of the genetic diversity of and contribute to its conservation and utilization.
绵参(Wall. ex Royle)是毛茛科的一个物种,主要分布于青藏高原海拔2700 - 4000米的林缘和草坡。尽管它在高山生态系统中分布广泛,但其遗传多样性仍知之甚少。在本研究中,我们组装并表征了绵参的完整叶绿体基因组,填补了我们对其遗传组成理解上的重大空白。叶绿体基因组长度为155,864个碱基对,包含131个基因,其中包括86个蛋白质编码基因、37个tRNA基因和8个rRNA基因。对15个有代表性的绵参属物种进行的系统发育分析表明,该属可分为三个进化枝。绵参与另外九个物种形成了最大的单系进化枝,并且与长叶乌头和展毛乌头关系最为密切。这些发现增进了我们对绵参遗传多样性的理解,并有助于其保护和利用。
