Angiosperms are by far the most species-rich clade of land plants, but their origin and early evolutionary history remain poorly understood. We reconstructed angiosperm phylogeny based on 80 genes from 2,881 plastid genomes representing 85% of extant families and all orders. With a well-resolved plastid tree and 62 fossil calibrations, we dated the origin of the crown angiosperms to the Upper Triassic, with major angiosperm radiations occurring in the Jurassic and Lower Cretaceous.

Plastid phylogenomic insights into relationships of all flowering plant families
This work has assembled by far the largest plastid dataset of angiosperms and provides the most comprehensive dataset of plastomes to date and a well-resolved phylogenetic tree, which together provide a strong foundation for future evolutionary studies of flowering plants.
Phylogenomic Insights into Deep Phylogeny of Angiosperms Based on Broad Nuclear Gene Sampling
Fossil data support a pre-Cretaceous origin of flowering plants.
A Bayesian method is developed to estimate the ages of angiosperm families on the basis of the fossil record (a newly compiled dataset of ~15,000 occurrences in 198 families) and their living diversity and indicates that several families originated in the Jurassic, strongly rejecting a Cretaceous origin for the group.
Simultaneous diversification of Polypodiales and angiosperms in the Mesozoic
The estimated divergence patterns of Polypodiales and angiosperms converge to a scenario in which their main lineages were established simultaneously shortly before the onset of the Cretaceous Terrestrial Revolution, and further suggest a pre‐Cretaceous hidden history for both lineages.
A nuclear phylogenomic study of the angiosperm order Myrtales, exploring the potential and limitations of the universal Angiosperms353 probe set.
High-throughput sequencing and the Angiosperms353 probe kit are powerful tools for phylogenomic analysis, but better understanding of the genetic data available is required to identify genes and gene trees that account for likely incomplete lineage sorting and/or hybridization events.
Reconstructing Dipsacales phylogeny using Angiosperms353: issues and insights
A significant number of nuclear loci are sampled using a Hyb-Seq approach and these data are used to infer the Dipsacales phylogeny and estimate divergence times, indicating homoplasy in calyx morphology, ovary development, and fruit type.
Prickly waterlily and rigid hornwort genomes shed light on early angiosperm evolution
These genomes help to elucidate relationships among the major subclades within Mesangiospermae, which contain about 350,000 species and confirm that Amborella and Nymphaeales are successively sister to all other angiosperms.
The delayed and geographically heterogeneous diversification of flowering plant families
A new study of the divergence time of angiosperm families shows that the diversification of families into extant diversity was delayed until the Palaeocene, this time lag being geographically heterogeneous, and longer in tropical than in temperate and arid biomes.
Evidence for an extinct lineage of angiosperms from the Early Cretaceous of Patagonia and implications for the early radiation of flowering plants.
Whereas many Early Cretaceous angiosperms fall within the morphological range of extant taxa, Mesodescolea reveals unexpected early morphological and ecophysiological trends.
Hundreds of nuclear and plastid loci yield insights into orchid relationships
This study provides the first robust nuclear phylogenomic framework for Orchidaceae plus an assessment of intragenomic nuclear discordance, plastid-nuclear tree incongruence, and phylogenetic informativeness across the family.


The earliest angiosperms: evidence from mitochondrial, plastid and nuclear genomes
This study demonstrates that Amboreella, Nymphaeales and Illiciales-Trimeniaceae-Austrobaileya represent the first stage of angiosperm evolution, with Amborella being sister to all other angiosperms, and shows that Gnetales are related to the conifers and are not sister to the angios perms, thus refuting the Anthophyte Hypothesis.
Molecular and Fossil Evidence on the Origin of Angiosperms

Molecular data on relationships within angiosperms confirm the view that their increasing morphological diversity through the Cretaceous reflected their evolutionary radiation and appear to refute the hypothesis based on morphology that angiosPerms and Gnetales are closest living relatives.
Resolution of deep angiosperm phylogeny using conserved nuclear genes and estimates of early divergence times
The molecular clock estimates of Mesangiospermae diversification during the late to middle Jurassic correspond well to the origins of some insects, which may have been a factor facilitating early angiosperm radiation.
Palaeobotanical redux: revisiting the age of the angiosperms
Critical assessment of reports shows that, so far, none provide unequivocal evidence of pre-Cretaceous angiosperms, but credible palaeobotanical evidence will require unambiguous documentation of the diagnostic structural features that separate angiospheric groups of extant and extinct seed plants.
Using plastid genome-scale data to resolve enigmatic relationships among basal angiosperms
Parsimony analyses of combined and partitioned data sets varied in the placement of several taxa, particularly Ceratophyllum, whereas maximum-likelihood (ML) trees were more topologically stable, and ML bootstrap and Bayesian support values for these relationships were generally high, although approximately unbiased topology tests could not reject several alternative topologies.
Ferns diversified in the shadow of angiosperms
It is shown that polypod ferns (> 80% of living fern species) diversified in the Cretaceous, after angiosperms, suggesting perhaps an ecological opportunistic response to the diversification of angios perms, as angiosPerms came to dominate terrestrial ecosystems.
The age and diversification of the angiosperms re-revisited.
These analyses provide a new comprehensive source of reference dates for major angiosperm clades that are generally younger than other recent molecular estimates and very close to dates inferred from the fossil record.
A metacalibrated time-tree documents the early rise of flowering plant phylogenetic diversity.
This time-frame documents an early phylogenetic proliferation that led to the establishment of major angiosperm lineages, and the origin of over half of extant families, in the Cretaceous.
Angiosperm phylogeny: 17 genes, 640 taxa.
It is confirmed that with large amounts of sequence data, most deep-level relationships within the angiosperms can be resolved and will be of broad utility for many areas of biology, including physiology, ecology, paleobiology, and genomics.
Plastid phylogenomic analysis of green plants: A billion years of evolutionary history.
This plastid data set provides an important resource for elucidating morphological evolution, dating divergence times in Viridiplantae, comparisons with emerging nuclear phylogenies, and analyses of molecular evolutionary patterns and dynamics of the plastids.
