How barriers to gene flow arise and are maintained are key questions in evolutionary
biology. Speciation research has mainly focused on barriers that occur either before mating …

Standard plant DNA barcodes based on 2–3 plastid regions, and nrDNA ITS show variable
levels of resolution, and fail to discriminate among species in many plant groups. Genome …

Abstract Pollination studies in East Asia have been develo** rapidly in recent decades.
East Asia may provide important information on many aspects of plant-pollinator interactions …

Abstract Background and Aims Rhododendron is a species-rich and taxonomically
challenging genus due to recent adaptive radiation and frequent hybridization. A well …

Abstract Background The Rhododendron sanguineum complex is endemic to alpine
mountains of northwest Yunnan and southeast Tibet of China. Varieties in this complex …

Understanding how different driving forces have promoted biological divergence and
speciation is one of the central issues in evolutionary biology. The Triticum/Aegilops species …

After the merger of the former Taxodiaceae and Cupressaceae ss, currently the conifer
family Cupressaceae (sensu lato) comprises seven subfamilies and 32 genera, most of …

Background Natural hybridization can influence the adaptive response to selection and
accelerate species diversification. Understanding the composition and structure of hybrid …

Premise The genetic structure of hybrid zones provides insight into the potential for gene
flow to occur between plant taxa. Four closely related European orchid species (Orchis …

Hybridization can often lead to the formation of novel taxa which can have traits that
resemble either or both parental species. Determining the similarity of hybrid traits to …
