Abstract

The complete plastome of Spiraea trilobata, a shrub, is determined. The plastome is 155,981 bp in length and comprises a large single-copy region (84,417 bp), a small single-copy region (18,878 bp), and a pair of inverted repeats regions (26,343 bp). A total of 113 unique genes are annotated for the plastome of S. trilobata, containing 79 protein coding genes (PCGs), 30 tRNAs, and four rRNAs. The GC content of this plastome is 36.8%. Phylogenomic analysis based on 17 plastomes reveals that S. trilobata is sister to Spiraea blumei. Compared with S. blumei, S. trilobata lacks both trnM-CAU and ycf1. In addition, the GC content of both species is the same.

Keywords: Spiraea trilobata; complete plastome; phylogeny.
