title: Deciphering the evolutionary interplay between subgenomes following polyploidy: A paleogenomics approach in grasses.
abstract: How did plant species emerge from their most recent common ancestors (MRCAs) 250 million years ago? Modern plant genomes help to address such key questions in unveiling precise species genealogies. The field of paleogenomics is undergoing a paradigm shift for investigating species evolution from the study of ancestral genomes from extinct species to deciphering the evolutionary forces (in terms of duplication, fusion, fission, deletion, and translocation) that drove present-day plant diversity (in terms of chromosome/gene number and genome size). In this review, inferred ancestral karyotype genomes are shown to be powerful tools to (1) unravel the past history of extant species by recovering the variations of ancestral genomic compartments and (2) accelerate translational research by facilitating the transfer of genomic information from model systems to species of agronomic interest.
