The complete chloroplast genome of the Korean endemic plant Sorbaria sorbifolia var. glandulifolia J.-H. Song & S.-P. Hong (Rosaceae) and phylogenetic analysis

Sorbaria sorbifolia var. glandulifolia, endemic to Korea, is distinguished by glandular trichomes on the abaxial leaflet surface. In this study, we present its first complete chloroplast genome (159,476 bp) with a typical quadripartite structure comprising 112 unique genes, including 78 protein-coding genes, 30 transfer RNAs, and four ribosomal RNAs. Phylogenetic analysis of 18 complete chloroplast genomes revealed that S. sorbifolia var. glandulifolia forms a monophyletic group with other Sorbaria species and clusters with Adenostoma. Furthermore, two well-supported clades within Sorbaria corresponded to the sections Sorbaria and Kirilowiana. This study provides the first chloroplast genome report for S. sorbifolia var. glandulifolia, offering valuable genomic insights for future phylogenetic and taxonomic research on the genus Sorbaria.
