N2 - Despite its high economic importance, little is known about rose genetics, genome structure, and the function of rose genes. Reasons for this lack of information are polyploidy in most cultivars, simple breeding strategies, high turnover rates for cultivars, and little public funding. Molecular and biotechnological tools developed during the genomics era now provide the means to fill this gap. This will be facilitated by a number of model traits as e.g., a small genome, a large genetic diversity including diploid genotypes, a comparatively short generation time and protocols for genetic engineering. A deeper understanding of genetic processes and the structure of the rose genome will serve several purposes: Applications to the breeding process including marker-assisted selection and direct manipulation of relevant traits via genetic engineering will lead to improved cultivars with new combinations of characters. In basic research, unique characters, e.g., the biosynthesis and emission of particular secondary metabolites will provide new information not available in model species. Furthermore comparative genomics will link information about the rose genome to ongoing projects on other rosaceous crops and will add to our knowledge about genome evolution and speciation. This review is intended as a presentation and is the compilation of the current knowledge on rose genetics and genomics, including functional genomics and genetic engineering. Furthermore, it is intended to show ways how knowledge on rose genetics and genomics can be linked to other species in the Rosaceae in order to utilize this information across genera.
