摘要
Saxifraga giraldiana Engler 是一种常见的亚高山和高山植物，属于虎耳草科。然而，该物种的遗传多样性仍有待探索。在这项研究中，我们组装并鉴定了 S. giraldiana 的完整叶绿体基因组，填补了这一知识空白，并揭示了其遗传组成。叶绿体基因组长 147,267 bp，包含 131 个基因，其中包括 85 个蛋白质编码基因、38 个 tRNA 基因和 8 个 rRNA 基因。此外，我们还对 Saxifraga 中的 19 个代表性物种进行了系统发育分析。结果发现，S. giraldiana 与 S. implicans 和 S. stellariifolia 构成一个单系群。这些发现对保护和利用 S. giraldiana 具有重要意义。
The complete plastome of Saxifraga giraldiana Engler and its phylogenetic analysis.
Saxifraga giraldiana Engler is a common subalpine and alpine plant belonging to Saxifragaceae. However, the genetic diversity of this species has remained to be explored. In this study, we have assembled and characterized the complete chloroplast genome of S. giraldiana, filling this knowledge gap and uncovering its genetic composition. The chloroplast genome is 147,267 bp long and contains 131 genes, including 85 protein-coding genes, 38 tRNA genes, and eight rRNA genes. Furthermore, we have performed a phylogenetic analysis of 19 representative species within Saxifraga. As a result, we have found that S. giraldiana, together with S. implicans and S. stellariifolia, forms a monophyletic group. These findings have implications for the conservation and utilization of S. giraldiana.
