The complete plastome of Saxifraga giraldiana Engler and its phylogenetic analysis.

Abstract

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.
