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...

Limited seed and pollen gene dispersal in Taxus baccata

Dispersal is crucial due to its direct impact on dynamics of a species’ distribution as well as having a role in shaping adaptive potential...

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...

Chinese aspen with a dynamic Quaternary evolutionary history

Populus adenopoda (Salicaceae), the Chinese aspen, occurs in the subtropical China region. Fen et al. report a genetic survey to reveal that it survived...

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...

Endogenous Banana Streak Viruses illuminate Musa balbisiana diversity

Banana streak viruses (BSV) present in the B genome of banana or plantain cultivars give rise to spontaneous infections following abiotic stresses. Because cooking...

Maintenance of plant species cohesion despite ongoing hybridization

When species cohesion is maintained despite ongoing natural hybridisation.

Where do olives come from?

An analysis of patterns of genetic differentiation finds evidence of reciprocal gene exchanges between populations of Mediterranean and Saharan olives.

Individual mating patterns in mixed oak stands

Trees can mate assortatively, which may be a result of variable compatibility among trees due to genetic and/or environmental factors.

Single-copy nuclear genes for palm phylogenetics

Molecular phylogenetic studies of palms (Arecaceae) have not yet provided a fully resolved phylogeny of the family. Ludeña et al. test the value of AGAMOUS...

Plants from different climates can react to drought in similar ways

How do plants react when circumstances change? One method can be to evolve a local adaptation. Another can be be phenotypic plasticity,...

Not All Pine Needles Are Identical: Lower Crown Loss in Pinus radiata

When fungal infection comes to Pinus radiata, it can run through the bottom of the crown of the tree, removing its leaves....

How do you get more DNA down a pollen tube?

A common event for flowering plants is whole genome duplication (WGD), where a plant gets extra chromosomes. It’s often studied in mature...

Simulating the effects of local adaptation and life history on the ability of plants to track climate shifts

Local adaptation is common but not universal in plants and results from the interplay of gene flow with natural selection. Gene flow...
