Sorbus is a highly diverse tree genus but is this the result of hybridisation and introgression between native and foreign species?

Using genetic analyses to understand population structure and genet assignment of a clonal forest-floor herb
Tsujimoto et al. investigated how ramets belonging to different genets were distributed in a natural population of Carrdamine leucantha in Hokkaido, Japan.
Multiple parallel dispersal events and mosaic genetic structure in Dactylorhiza
Orchids have minute seeds and can disperse over long distances. Hedrén et al. use genetic markers to track how the marsh orchid Dactylorhiza majalis ssp. lapponica (Orchidaceae) colonised...

The impact of floral morphology on genetic differentiation in two closely related biennial plant species
The genetic diversity and structure of plant populations are determined by the interaction of gene flow, genetic drift and natural selection. These processes are to some extent dependent on the mating system of plants...
Genetic diversity and structure of an endangered medicinal herb: implications for conservation
Human-driven habitat fragmentation leads to spatial isolation of endangered plant species, increasing extinction risk. Understanding genetic variability and population structure of rare and isolated plant species is of...
Geographic population structure in an outcrossing plant invasion after centuries of cultivation and recent founding events
Population structure and genetic diversity of plant invasions are the result of evolutionary processes such as natural selection, drift and founding events. Some invasions are also molded by specific human activities...
Analysis of population genetic structure and gene flow in an annual plant before and after a rapid evolutionary response to drought
Climate change can have widespread and devastating impacts, but little is known about the effects of this change on the genetics of natural populations. In a new study published in AoB PLANTS, Welt et al. aimed to...

Population structure and domestication events within Cynara
Globe artichoke and leafy cardoon are two crops belonging to the same species, Cynara cardunculus (Asteraceae). Gatto et al. analyse population structure and genetic relationships between var. scolymus (artichoke), var...
