Hybridization and genome duplication for early evolutionary success in the Asian Palmate group of Araliaceae

The phenomenal advances in sequencing techniques and analytical development during the last decade have provided a unique opportunity to unravel evolutionary history of lineages under complex patterns evolution. This is case largest clade ginseng family (Araliaceae), Asian Palmate group (AsPG), where large internal polytomies genome incongruences detected previous studies pointed scenario radiation with hybridization events between genera for early evolution group. In this study, we aim obtain well-resolved nuclear plastid phylogenies AsPG using Hyb-Seq evaluate hypothesis assess role We performed concatenated- coalescent-based phylogenetic analyses from 936 targeted loci 261 obtained 72 species representing 20 main clades Araliaceae. impact incomplete lineage sorting (ILS) was assessed SNaQ, duplications were evaluated ChromEvol. Our are compatible AsPG. Also, identification extensive signals ILS behind supports as major driving force radiation. hypothesize whole-genome duplication event at origin AsPG, followed by that led ILS, which, alongside inter-genera hybridization, obscuring signal clade.
