Studies of plants have been instrumental for revealing how new species originate. For
several decades, botanical research has complemented and, in some cases, challenged …

Sympatric speciation illustrates how natural and sexual selection may create new species in
isolation without geographic barriers. However, recent genomic reanalyses of classic …

The relative importance of introgression for diversification has long been a highly disputed
topic in speciation research and remains an open question despite the great attention it has …

It is increasingly realized that homoploid hybrid speciation (HHS), which involves no change
in chromosome number, is an important mechanism of speciation. HHS will likely increase in …

Most new cryptic species are described using conventional tree‐and distance‐based
species delimitation methods (SDMs), which rely on phylogenetic arrangements and …

Hybridization and resulting introgression are important processes shaping the tree of life
and appear to be far more common than previously thought. However, how the genome …

Mandarin (Citrus reticulata) is one of the most important citrus crops worldwide. Its
domestication is believed to have occurred in South China, which has been one of the …

Phylogenetic analysis is complicated by interspecific gene flow and the presence of shared
ancestral polymorphisms, particularly those maintained by balancing selection. In this study …

Genome scans can potentially identify genetic loci involved in evolutionary processes such
as local adaptation and gene flow. Here, we show that recombination rate variation across a …

Dioecy, the presence of separate sexes on distinct individuals, has evolved repeatedly in
multiple plant lineages. However, the specific mechanisms by which sex systems evolve and …
