Subgenome-Level Phylogeny Reveals an Allopolyploid Origin of Chloranthales from Ancestral Monocot and Eudicot Lineages
Subgenome-resolved phylogenomic analyses revealed that the dominant Chloranthales subgenome exhibits phylogenetic affinity with eudicots, whereas the recessive subgenome is associated with monocots, indicating a deep reticulate origin involving ancestral lineages related to these major angiosperm clades.
