The chloroplasts genomic analyses of Rosa laevigata, R. rugosa and R. canina.

ABSTRACT:

Background

Many species of the genus Rosa have been used as ornamental plants and traditional medicines. However, industrial development of roses is hampered due to highly divergent characteristics.

Methods

We analyzed the chloroplast (cp) genomes of Rosa laevigata, R. rugosa and R. canina, including the repeat sequences, inverted-repeat (IR) contractions and expansions, and mutation sites.

Results

The size of the cp genome of R. laevigata, R. rugosa and R. canina 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, trnS-GCU, trnG-GCC, psbA-trnH, t
