# Characterization and phylogenetic consideration of the complete chloroplast genome of spiraea uratensis (rosaceae)

## TL;DR

This study sequenced the complete chloroplast genome of Spirea uratensis and found it shares a close evolutionary relationship with other Spirea species.

## Contribution

The complete chloroplast genome of Spirea uratensis is characterized and used to infer phylogenetic relationships within the Rosaceae family.

## Key findings

- The chloroplast genome of S. uratensis is 155,876 bp with typical quadripartite structure.
- Phylogenetic analysis shows five Spirea species form a monophyletic group.
- The genome contains 132 genes and has a GC content of 36.8%.

## Abstract

Spirea uratensis is a shrub plant valued for its ecological and ornamental qualities. In this study, we assembled the complete chloroplast genomes of S. uratensis. The result revealed a 155,876 bp circular structure with typical quadripartite organization: 84,291 bp LSC, 18,893 bp SSC, and two 26,346 bp IRs. The genome contains 132 genes and has 36.8% GC content. Phylogenetic analyses resolved S. uratensis, S. henryi, S. ovalis, S. nipponica, and S. trichocarpa forming a monophyletic group, confirming their close relationship. This study advances understanding of chloroplast evolution in Spirea of Rosaceae.
