Molecular markers from the chloroplast genome of rose provide a complementary tool for variety discrimination and profiling.

ABSTRACT: The rose is one of the most important ornamental woody plants because of its extensive use and high economic value. Herein, we sequenced a complete chloroplast genome of the miniature rose variety Rosa 'Margo Koster' and performed comparative analyses with sequences previously published for other species in the Rosaceae family. The chloroplast genome of Rosa 'Margo Koster', with a size of 157,395 bp, has a circular quadripartite structure typical of angiosperm chloroplast genomes and contains a total of 81 protein-coding genes, 30 tRNA genes and 4 rRNA genes. Conjunction regions in the chloroplast genome of Rosa 'Margo Koster' were verified and manually corrected by Sanger sequencing. Comparative genome analysis showed that the IR contraction and expansion events resulted in rps19 and ycf1
