How does mixed mating persist, when self-pollination ensures a plant won’t reproduce?
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.

Population structure of Betula albosinensis and B. platyphylla
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...

Patterns of mtDNA variation reveal complex evolutionary history of a relict and endangered peat bog pine
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...
Seed characteristic variations and genetic structure of wild Zizania latifolia along a latitudinal gradient in China
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...

Shaping the cline of floral calyx lobe length in Asarum
Divergent selection may have driven the calyx lobe length variation in series Sakawanum taxa, although the underlying mechanism is still not clear.
Evolving towards introgression: hybridization and hybrid swarms
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...
Genetic diversity of wild papaya
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...
Genetic structure of Old World date palm
Population structure analysis reveals the existence of two ancient gene pools that have contributed to the current diversity of Old World date palm.
Pollen dispersal and breeding structure in Petunia
Results show that most pollen dispersal in subsp. axillaris occurs within populations and there is a high proportion of inbreeding.
Genetic diversity of high-elevation populations of an endangered medicinal plant
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...

Genetic and morphological signature of ancient Agave cultivation
Parker et al. test whether formerly cultivated Agave parryi populations still bear a predictable genetic and morphological signature.
