Until recently, molecular phylogenies based on a single or few orthologous genes often
yielded contradictory results. Using multiple genes in a large concatenation was proposed to …

The plastome of land plants is often considered to be highly conserved in sequence,
structure, and content. This is particularly true for nonvascular land plants, for which few …

Background Flowering plants (angiosperms) are dominant components of global terrestrial
ecosystems, but phylogenetic relationships at the familial level and above remain only …

Reconstructing the origin and evolution of land plants and their algal relatives is a
fundamental problem in plant phylogenetics, and is essential for understanding how critical …

Proteins have distinct structural and functional constraints at different sites that lead to site-
specific preferences for particular amino acid residues as the sequences evolve …

Background Next-generation sequencing has provided a wealth of plastid genome
sequence data from an increasingly diverse set of green plants (Viridiplantae). Although …

Polyploidy has long been recognized as a major force in angiosperm evolution. Recent
genomic investigations not only indicate that polyploidy is ubiquitous among angiosperms …

• Premise of the study: Recent analyses employing up to five genes have provided
numerous insights into angiosperm phylogeny, but many relationships have remained …

Although Pentapetalae (comprising all core eudicots except Gunnerales) include≈ 70% of
all angiosperms, the origin of and relationships among the major lineages of this clade have …

• Premise: Bromeliaceae form a large, ecologically diverse family of angiosperms native to
the New World. We use a bromeliad phylogeny based on eight plastid regions to analyze …
