The complete chloroplast genome sequence of Spiraea blumei G. Don (Rosaceae)

Abstract

Spiraea blumei G. Don is an ornamental shrub widely distributed in Eastern Asia. Here, we reported and characterized the complete chloroplast (cp) genome sequence of S. blumei (GenBank accession number: MN418904) to provide genomic resources for promoting its conservation. The total chloroplast genome is 155,957 bp in length and contains the typical chloroplast structure, including two inverted repeat (IR) regions of 26,343 bp, a large single-copy (LSC) region of 84,384 bp, and a small single-copy (SSC) region of 18,887 bp. The overall guanine-cytosine (GC) content of the S. blumei chloroplast genome is 36.8%. The cp genome encodes 133 unique genes, including 85 protein-coding genes (PCGs), 40 tRNA genes, and 8 rRNA genes. We used the cp genome of S. blumei and 26 other cp genomes to perform a phylogenetic analysis, which indicated that S. blumei was closely related to S. martini in Rosaceae.
