Resolving phylogenetic conflicts in Pandanales: the dual roles of gene flow and whole-genome duplication

Our findings indicate that gene flow, rather than incomplete lineage sorting, is the primary source of phylogenetic conflict at certain nodes within Pandanales. The identified WGD events likely played a significant role in facilitating adaptation and diversification under changing environmental conditions. These results not only resolve long-standing phylogenetic conflicts but also enhance our understanding of the mechanisms driving plant diversification within this order.
