Being a seed from self-pollination guarantees failure in Eucalyptus regnans. Yet despite this, new research shows a mixed-mating system. including selfing, is evolutionarily stable.
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...
Assessments of eco-evolutionary mechanisms that shape the genetic structure of populations are important to understand the influence of environmental changes on plant ecosystems.In recent years, molecular markers...
Crop wild relatives are important genetic resources for crop improvement, but they can also be candidates for crop domestication. Zizania latifolia is a perennial aquatic grass which was domesticated as a vegetable crop...
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...
In order to determine whether genetic architecture stems from pre-Pleistocene events or refugia, Chávez-Pesqueira and Núñez-Farfán assess genetic diversity and population dynamics of 19 populations of wild papaya...
Intraspecific genetic variation in natural populations governs their potential to overcome challenging ecological and environmental conditions. In addition, knowledge of this variation is critical for the conservation...
