However, industrial development of roses is hampered due to highly divergent characteristics.<h4>Methods</h4>We analyzed the chloroplast (cp) genomes of <i>Rosa laevigata, R. rugosa</i> and <i>R. canina</i>, including the repeat sequences, inverted-repeat (IR) contractions and expansions, and mutation sites.<h4>Results</h4>The size of the cp genome of <i>R. laevigata, R. rugosa</i> and <i>R. canina</i> was between 156 333 bp and 156 533 bp, and contained 113 genes (30 tRNA genes, 4 rRNA genes and 79 protein-coding genes). The regions with a higher degree of variation were screened out (trnH-GUU, <i>trnS</i>-<i>GCU</i>, <i>trnG</i>-<i>GCC</i>, <i>psbA</i>-<i>trnH</i>, <i>tChinese medicineThe chloroplasts genomic analyses of <i>Rosa laevigata, R. rugosa</i> and <i>R. canina</i>.PMC70203762017YFC1702100Liang CYin XLiao BPei JGuo SChen SXu JfalseThe chloroplasts genomic analyses of <i>Rosa laevigata, R. rugosa</i> and <i>R. canina</i>.<h4>Background</h4>Many species of the genus <i>Rosa</i> have been used as ornamental plants and traditional medicines.
