Uncovering the genomic signature of ancient introgression between white oak lineages (Quercus)

Summary Botanists have long recognised interspecific gene flow as a common occurrence within white oaks ( Quercus section Quercus ). Historical allele exchange, however, has not been fully characterised and the complex genomic signals resulting from the combination of vertical and horizontal gene transmission may confound phylogenetic inference and obscure our ability to accurately infer the deep evolutionary history of oaks. Using anchored...
