Abstract

Exochorda serratifolia (pearlbush) is a rosid shrub found in northeast Asia, including the Korean peninsula. This ornamental plant has white inflorescences and strong insect resistance; however, its genetic diversity is poorly understood and a complete plastid genome is unavailable. Here, we determined the complete chloroplast genome of E. serratifolia through de novo assembly using next-generation sequencing. The E. serratifolia chloroplast genome was 160,558 bp, comprising a large single-copy (LSC) region of 88,514 bp, a small single-copy (SSC) region of 19,308 bp, and two inverted repeat regions (IRs) of 26,368 bp each. We annotated 112 genes: 78 protein-coding genes, 30 tRNA genes, and four rRNA genes. This reference plastid genome increases our understanding of the phylogenetic relationships of E. serratifolia among Rosaceae plants.
