Abstract

Rosa glomerata is a diffuse shrub belonging to Rosa sect. Synstylae. It is endemic to Southwest China and of high ornamental and economic value. However, its systematic position remains unclear. Here, the complete chloroplast genome of R. glomerata was assembled using high-throughput sequencing data. The cp genome is 157,064 bp in length with a large single-copy region (LSC) of 86,216 bp, a small single-copy region (SSC) of 18,752 bp, and a pair of inverted repeats (IRs) of 26,048 bp. The overall GC content is 37.2%. A total of 137 genes were annotated, including 90 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis revealed that R. glomerata is closely related to R. praelucens of R. sect. Microphyllae rather than species of R. sect. Synstylae.
