Translational genomics is defined as the application of molecular-genetic principles derived from model systems to species of experimental or economic interest. The past 20 years of research in plant model systems such as Arabidopsis thaliana have relinquished vast amounts of information regarding gene function, the integration of genetic components into pathways, and the interrelationships between pathways to control form and function in plants and plant-products alike. At present, the challenge is to relate these paradigms to other species of economic or scientific interest. Apart from being an important and valuable crop, strawberry (Fragaria spp.) is a member of the Rosaceae, a plant family containing fruit, nut, ornamental and wood-bearing species. Strawberry is unique within the Rosaceae in that it is a rapidly growing herbaceous perennial with a small genome and the ability to thrive in a laboratory setting. Strawberry species may also be transformed and regenerated in a time scale of weeks or months instead of years. For these reasons, strawberry has been recognized as the translational genomics model for the Rosaceae family. This review summarizes and synthesizes the technical reports of strawberry regeneration and transformation, consolidating the large body of information regarding genetic modification of this important genus.
