Translational research consists in transferring fundamental knowledge gained from model species into applications in species of agronomical or medial interest. During the last decade, technological improvements led to the development of large sets of plant genomic resources permitting the emergence of high-resolution comparative genomic studies from model to crops. By conducting paleogenomics studies, delivering extinct ancestral genomes of modem plants, we identified common and lineage-specific patterns of gene conservation that allowed us to propose a model in which present-days plant genomes have evolved from a common ancestor with a basic number of seven chromosomes containing ~10’000 genes. Ancestral genomes can be considered as a guide to perform translational research of traits between models and crops, as it will be illustrated in grasses.
