Characterization of the complete chloroplast genome of Syringa wolfii.

Syringa wolfii (Syringa: Syringeae), an upright shrub, is ornamental species used in urban greenification. In this study, we determined the complete chloroplast (cp) genome of S. wolfii using next-generation sequencing (NGS). The size of the chloroplast genome is 156,571 bp in length, including a large single-copy region (LSC) of 86,684 bp, a small single-copy region (SSC) of 19,109 bp, and a pair of inverted repeat (IR) regions with 25,362 bp. The GC content of the chloroplast genome was 37.95%. Moreover, a total of 131 functional genes were annotated, including 87 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. The neighbor-joining phylogenetic tree suggested that S. wolfii was closely related to S. yunnansis.
