What creates Gentiana diversity in mountains?

The Qinghai-Tibetan Plateau (QTP) is extremely rich in species, but why? One recent explanation is the mountain‐geobiodiversity hypothesis (MGH) by Mosbrugger et...

Habitat partitioning through reproductive interference in Geranium

We’re familiar with seeing insects flit from one flower to the next, carrying pollen as they do so. What happens when they...

European white oak hybrids can be well-identified with a small set of genetic markers

A limited set of SNPs identified the species of test trees with a high degree of accuracy, finding asymmetrical mixing among the three species.

Evolution of increased vigour associated with allopolyploidization in a newly formed invasive species

Polyploidy (whole genome duplication) is one of the most important processes in plant evolution. Most land plants have an evolutionary history that...

Hybrids may succeed where invasive species fail as sea levels rise

Invasive species might suffer from a change in conditions in tidal areas, but their hybrid offspring may have genes to survive.

The Miscanthus sacchariflorus homeland lies beneath the waves

A study of the genetic diversity of Miscanthus sacchariflorus has revealed that the centre of its diversity now lies under the Yellow Sea.

Origin and genome evolution of Cardamine occulta

For the first time, whole-genome cytogenomic maps were established for octoploid plants.

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...

Mechanisms of reproductive interference in Taraxacum

Reproductive interference can reduce fitness of either of the involved species, and its ecological and evolutionary consequences may depend on its underlying mechanisms.

AoBP special issue announcement: Population differentiation in plants

Plant populations continually change over space and time. Many factors contribute to this differentiation with some resulting in evolutionary change. Unravelling the relative importance...

Changes in How a Plant Breathes Aren’t Always Matched by Changes in Its Anatomy

You can't predict how a Yucca gloriosa will react to drought from its anatomy alone.

New grapevine model better predicts whole-canopy gas exchange

Models considering only the maximum photosynthetic capacity for all leaves over-estimated net carbon dioxide exchange by nearly a third.

Phylogeny, age and adaptive evolution of genus Allium

The genus Allium L., one of the largest monocotyledonous genera and one that includes many economically important crops with nutritional and medicinal...

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,...
