A chloroplast tree for Viburnum (Adoxaceae) and its implications for phylogenetic classification and character evolution.
• Premise of the study: Despite recent progress, significant uncertainties remain concerning relationships among early-branching lineages within Viburnum (Adoxaceae), prohibiting a new classification and hindering studies of character evolution and the increasing use of Viburnum in addressing a wide range of ecological and evolutionary questions. We hoped to resolve these issues by sequencing w...
متن کاملThe Evolution of Reproductive Characters in Dipsacales
Improved knowledge of Dipsacales phylogeny provides a solid framework for studies of character evolution. Although the polarity of many characters can now be confidently established, for others it remains unclear. This results largely from uncertainty about the broader relationships of Dipsacales and is especially problematic for characters that differentiate the two basal lineages, Adoxaceae a...
متن کاملScalariform-to-simple transition in vessel perforation plates triggered by differences in climate during the evolution of Adoxaceae
BACKGROUND AND AIMS Angiosperms with simple vessel perforations have evolved many times independently of species having scalariform perforations, but detailed studies to understand why these transitions in wood evolution have happened are lacking. We focus on the striking difference in wood anatomy between two closely related genera of Adoxaceae, Viburnum and Sambucus, and link the anatomical d...
متن کاملPhylogenetic and Experimental Tests of Interactions among Mutualistic Plant Defense Traits in <italic>Viburnum</italic> (Adoxaceae)
Plant traits that mediate mutualistic interactions are widespread, yet few studies have linked their macroevolutionary patterns with the ecological interactions they mediate. Here we merged phylogenetic and experimental approaches to investigate the evolution of two common mutualistic plant traits, extrafloral nectaries (EFNs) and leaf domatia. By using the flowering plant clade Viburnum, we te...
متن کاملViburnum Phylogeny Based on Chloroplast trnK Intron and Nuclear Ribosomal ITS DNA Sequences
Phylogenetic analyses of chloroplast trnK intron and nuclear ribosomal ITS DNA sequences yield signicant improvements in our understanding of relationships, character evolution, and biogeography in Viburnum (Adoxaceae). We conrm that most of the ten traditionally recognized sections are monophyletic. The most striking exception is Odontotinus, which is divided into: (i) a purple-fruited New W...
