Functional genomics is an emerging technological frontier in Rosaceous fruit production systems. Genome resources for important species are being generated at an increasing rate, allowing new perspectives on important traits. We delve into examples in pome fruits, where we explore genes and gene families in Pyrus and Malus genomes. We then zoom out and show how a comparative framework built on PlantTribes gives us perspective on important traits, and show how this approach is being used in functional genomics research on postharvest fruit quality. Next, we discuss progress of a collaborative project to bring gene family classifications to the Genome Database for Rosaceae. This includes a survey and assessment of genomes that will be used in a PlantTribes scaffold that is being built specifically to classify Rosaceae genomes, and an update on the results of genomes classification of many economically important Rosaceous fruit tree species.
