Angiosperm phylogeny based on matK sequence information.
Combined analyses of matK and other rapidly evolving DNA regions with available multigene data sets have strong potential to enhance resolution and internal support in deep level angiosperms phylogenetics and provide additional insights into angiosperm evolution.

It is found that Proteaceae, a model plant group for the Mediterranean hotspots of the Southern Hemisphere with a very rich pollen fossil record, diversified under higher rates in the Cape Floristic Region and Southwest Australia than in any other area of their total distribution.
Testing the impact of calibration on molecular divergence times using a fossil-rich group: the case of Nothofagus (Fagales).
It is suggested that increased background research should be made at all stages of the calibration process to reduce errors wherever possible, from verifying the geochronological data on the fossils to critical reassessment of their phylogenetic position.
Molecular dating of the ‘Gondwanan’ plant family Proteaceae is only partially congruent with the timing of the break‐up of Gondwana
Whether the present distribution of Proteaceae can be explained by vicariance caused by the break‐up of Gondwana is tested.

Phylogenetic analyses of Myristicaceae confirm that the ancestral area was Africa‐Madagascar and that Asian taxa are derived, but the family as a whole show strikingly lower molecular divergence than Annonaceae, indicating either a much younger age or a marked slowdown in molecular evolution.
Phylogeny of the bee genus Halictus (Hymenoptera: halictidae) based on parsimony and likelihood analyses of nuclear EF-1alpha sequence data.
The ancestral state for the genus Halictus is eusociality, and reversal to solitary behavior has occurred at least four times among the species included in this analysis.
Phylogenetic analysis of Magnoliales and Myristicaceae based on multiple data sets: implications for character evolution
Magnoliales, consisting of six families of tropical to warm-temperate woody angiosperms, were long considered the most archaic order of flowering plants, but molecular analyses nest them among other…
Five major shifts of diversification through the long evolutionary history of Magnoliidae (angiosperms)
The ages of the main clades of Magnoliidae (above the family level) are older than previously thought, and in several lineages, there were significant increases and decreases in net diversification rates.
Evolutionary radiations of Proteaceae are triggered by the interaction between traits and climates in open habitats
Divergent selection may have caused lineages in open vegetation types to evolve towards trait and climatic niche optima distinct from those in closed forests, and the interaction between open habitats, dry, warm and/or mediterranean climates, and small, sclerophyllous, toothed leaves increases net diversification rates in Proteaceae.
