Comparative analysis of the chloroplast genomes of Rosa species and RNA editing analyses

The genus Rosa (Rosaceae) contains about 200 species, most of these species have high ecological and economic values. Chloroplast genome sequences are important for studying species differentiation, phylogeny, and RNA editing. In present study, the chloroplast genomes of three Rosa species (R. hybrida, R. acicularis, and R. rubiginosa) were assembled and compared with other reported Rosa chloroplast genomes. To fully investigate the RNA editing sites in R. hybrida (commercial rose cultivar), we used RNA-Seq sequencing data mapping to the chloroplast genome and analyze their post-transcriptional features.
