Phylotranscriptomic analyses reveal the evolutionary complexity of <i>Paris</i> L. (Melanthiaceae), a morphologically distinctive genus with significant pharmaceutical importance

Our data suggest that the previously observed cytonuclear discordance in the phylogeny of Paris can primarily be attributed to recurrent hybridization events, with secondary contributions from infrequent ILS events. The recurrent hybridization events in the evolutionary history of Paris not only drove lineage diversification and speciation but also facilitated morphological innovation, and enhanced ecological adaptability. Therefore, artificial hybridization has great potential for breeding medicinal Paris species. These findings significantly contribute to our comprehensive understanding of the evolutionary complexity of this pharmaceutically significant plant lineage, thereby facilitating effective exploitation and conservation efforts.
