Differences in local abundance and ploidy level are predicted to impact the direction of introgression between species. Hu et al. test these hypotheses on Chinese populations of Betula albosinensis (red birch...
Reproductive interference can reduce fitness of either of the involved species, and its ecological and evolutionary consequences may depend on its underlying mechanisms.
Plant populations continually change over space and time. Many factors contribute to this differentiation with some resulting in evolutionary change. Unravelling the relative importance of ecological and genetic...
The distribution of plant species around the Mediterranean basin is a product of the influence of both geographical barriers and of climatic changes experienced during the Tertiary, with the transition from a warm to a...
The outcomes of natural hybridization are incredibly varied, ranging from hybrid speciation to extinction of parental taxa. Orphan hybrid populations or lineages are those that occur in the absence of the parental taxa...
Hybridization is a common process that leads to relevant evolutionary and ecological consequences. The genotypes resulting from hybridization commonly show phenotypic traits with intermediate values between both...
The extent to which hybridization leads to gene flow between plant species depends on the structure of hybrid populations. To assess possible variation in a hybrid population structure, Yan et al. evaluate magnitude and...
Asexual reproduction is relatively common in higher plants and comprises vegetative reproduction or clonal reproduction through seeds (apomixis or agamospermy). Apomixis is found in less than 1% of angiosperms and...
Allopolyploidy combined with apomixis is a partnership that generates novel species in many plant taxa, including the genus Sorbus. Uhrinová et al. use chloroplast and nuclear markers as well as flow cytometry to reveal...
A propensity to form polyploid hybrids is a peculiar feature of roses. Herklotz and Ritz investigate the population genetics of forty five mixed stands of dog roses across Central and South-Eastern Europe using...
Flora Unveiled: The Discovery and Denial of Sex in Plants. Lincoln Taiz and Lee Taiz. Oxford University Press, 2017. Living in the 21st century with easy access to knowledge – and its various fake versions – on the...
The Balkan Peninsula is one of the most important centres of plant diversity in Europe. Yet its flora is still largely unexplored and calls for further investigations. Olšavská et al. focus on Balkan taxa of the Cyanus...
