  text: Many recent studies have addressed the mechanisms operating during the early
    stages of speciation, but surprisingly few studies have tested theoretical predictions
    on the evolution of strong reproductive isolation (RI). To help address this gap,
    we first undertook a quantitative review of the hybrid zone literature for flowering
    plants in relation to reproductive barriers. Then, using Populus as an exemplary
    model group, we analysed genome-wide variation for phylogenetic tree topologies
    in both early- and late-stage speciation taxa to determine how these patterns
    may be related to the genomic architecture of RI. Our plant literature survey
    revealed variation in barrier complexity and an association between barrier number
    and introgressive gene flow. Focusing on Populus, our genome-wide analysis of
    tree topologies in speciating poplar taxa points to unusually complex genomic
    architectures of RI, consistent with earlier genome-wide association studies.
    These architectures appear to facilitate the ‘escape’ of introgressed genome segments
    from polygenic barriers even with strong RI, thus affecting their relationships
    with recombination rates. Placed within the context of the broader literature,
    our data illustrate how phylogenomic approaches hold great promise for addressing
    the evolution and temporary breakdown of RI during late stages of speciation.
