Genome-scale angiosperm phylogenies based on nuclear, plastome, and mitochondrial datasets

Angiosperms dominate the Earth’s ecosystems and provide most of the basic necessities for human life. The major angiosperm clades comprise 64 orders, as recognized by the APG IV classification. However, the phylogenetic relationships of angiosperms remain unclear, as phylogenetic trees with different topologies have been reconstructed depending on the sequence datasets utilized, from targeted genes to transcriptomes. Here, we used currently available de novo genome data to reconstruct the phylogenies of 366 angiosperm species from 241 genera belonging to 97 families across 43 of the 64 orders based on orthologous genes from the nuclear, plastid, and mitochondrial genomes of the same species with compatible datasets. The phylogenetic relationships were largely consistent with previously constructed phylogenies based on sequence variations in each genome type. However, there were major inconsistencies in the phylogenetic relationships of the five Mesangiospermae lineages when different ge..., ,
