The origin of the flower was a key innovation in the history of complex organisms,
dramatically altering Earth's biota. Advances in phylogenetics, developmental genetics, and …

An update of the Angiosperm Phylogeny Group (APG) classification of the orders and
families of angiosperms is presented. Several new orders are recognized: Boraginales …

Species tree reconstruction is complicated by effects of incomplete lineage sorting,
commonly modeled by the multi-species coalescent model (MSC). While there has been …

Perianth bilateral symmetry (zygomorphy) has evolved repeatedly from radial symmetry
(actinomorphy) throughout angiosperms. Zygomorphy has previously been linked with plant …

Lamiaceae, the sixth largest angiosperm family, contains more than 7000 species
distributed all over the world. However, although considerable progress has been made in …

The Boraginales are now universally accepted as monophyletic and firmly placed in
Lamiidae. However, a consensus about familial classification has remained elusive, with …

Savannas first began to spread across Africa during the Miocene. A major hypothesis for
explaining this vegetation change is the increase in C4 grasses, promoting fire. We …

We examine the eudicot order Myrtales, a clade with strong Gondwanan representation for
most of its families. Although previous phylogenetic studies greatly improved our …

We reconstructed a phylogenetic tree of Chinese vascular plants (Tracheophyta) using
sequences of the chloroplast genes atpB, matK, ndhF, and rbcL and mitochondrial matR. We …

Brassicales is a diverse order perhaps most famous because it houses Brassicaceae and,
its premier member, Arabidopsis thaliana. This widely distributed and species-rich lineage …
