Angiosperm divergence times are estimated using non–parametric rate smoothing and a three–gene dataset covering ca.
Angiosperm phylogeny inferred from 18S rDNA, rbcL, and atpB sequences
A phylogenetic analysis of a combined data set for 560 angiosperms and seven outgroups based on three genes, 18S rDNA, rbcL, and atpB representing a total of 4733 bp is presented, resulting in the most highly resolved and strongly supported topology yet obtained for angiosPerms.

The 2-locus combination of rbcL+matK will provide a universal framework for the routine use of DNA sequence data to identify specimens and contribute toward the discovery of overlooked species of land plants.

Analysis of >1,000 species of Mesoamerican orchids, DNA barcoding with matK alone reveals cryptic species and proves useful in identifying species listed in Convention on International Trade of Endangered Species (CITES) appendixes.
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.
Darwin's abominable mystery: Insights from a supertree of the angiosperms

A supertree of angiosperm families from published phylogenetic studies shows that diversification rate is a labile attribute of lineages at all levels of the tree, reflecting the interactive effects of biological traits and the environment.
Molecular phylogenetics of Caryophyllales based on nuclear 18S rDNA and plastid rbcL, atpB, and matK DNA sequences.

Two additional lineages are potentially appropriate to be elevated to the family level in the future: the genera Lophiocarpus and Corbichonia form a well-supported clade on the basis of molecular and chemical evidence, and Limeum appears to be separated from other Molluginaceae based on both molecular and ultrastructural data.
Oligocene CO2 Decline Promoted C4 Photosynthesis in Grasses
Phylogenetics of flowering plants based on combined analysis of plastid atpB and rbcL gene sequences.
A phylogenetic analysis of flowering plants based on a second plastid gene, atpB, analyzed separately and in combination with rbcL sequences for 357 taxa demonstrates that phylogenetics analysis of large matrices is feasible.
Preserving the evolutionary potential of floras in biodiversity hotspots
This work shows taxon richness to be decoupled from PD, using a biome-wide phylogenetic analysis of the flora of an undisputed biodiversity hotspot—the Cape of South Africa and demonstrates that PD protection is the best strategy for preserving feature diversity in the Cape.
