The evolutionary relationships among organisms have traditionally been represented using
rooted phylogenetic trees. However, due to reticulate processes such as hybridization or …

In lineages of allopolyploid origin, sets of homoeologous chromosomes may coexist that
differ in gene content and syntenic structure. Presence or absence of genes and …

Mountain systems harbor a substantial fraction of global biodiversity and, thus, provide
excellent opportunities to study rapid diversification and to understand the historical …

Abstract Redwood trees (Sequoioideae), including Metasequoia glyptostroboides (dawn
redwood), Sequoiadendron giganteum (giant sequoia), and Sequoia sempervirens (coast …

Replicated radiations, in which sets of similar forms evolve repeatedly within different
regions, can provide powerful insights into parallel evolution and the assembly of functional …

The evolutionary implications and frequency of hybridization and introgression are
increasingly being recognized across the tree of life. To detect hybridization from multi-locus …

Abstract Background and Aims Hybridization has long been recognized as an important
process for plant evolution and is often accompanied by polyploidization, another prominent …

Introgressive hybridization is widespread in wild plants and has important consequences.
However, frequent hybridization between species makes the estimation of the species' …

Interspecific hybridization may act as a major force contributing to the evolution of
biodiversity. Although generally thought to reduce or constrain divergence between 2 …

Hybridization events complicate the accurate reconstruction of phylogenies, as they lead to
patterns of genetic heritability that are unexpected under traditional, bifurcating models of …
