In the world of plants, love is complex, and new research reveals a surprising twist in how some plants overcome their self-incompatibility to self-fertilise.

Transgenerational effects of heat stress in Arabidopsis thaliana
Heat stress can have transgenerational effects on a plant's offspring but how important are the timing and frequency of these events?

Range expansion of Galinsoga quadriradiata into the mountains of China
Can shifts in trait values among populations of an invasive plant help assess invasion risks and predict future spread?
The importance of quantitative trait differentiation in habitat restoration
Successful restoration of habitats relies on the sourcing of seed appropriate to the restoration environment. The use of non-adapted genotypes can compromise the long-term success of restoration programmes if fitness of...
Contributions of microenvironmental variation to population persistence under climate change
The environment can vary at small spatial scales, so small that neighbouring plants in a natural population can grow with different resource levels and experience different degrees of competition. This fine-grained...
Role of ploidy in Arabidopsis arenosa colonization of alpine habitats
Doubling the chromosomes of Arabidopsis arenosa does not always lead to strong ecological niche differentiation.

Variations in climate can cause genetic diversity in plant populations
A new paper in Science highlights how variation in an environment can mean plants have no single solution for survival. Where conditions change, genetic diversity can be the best option for a species.

Generating, capturing and utilising genetic variation at Bioenergy Genomics 2017
Where will the genes to improve biofuels come from? Jack Bailey-Bale looks ahead to the Generating, capturing and utilising genetic variation session at Bioenergy Genomics 2017.

Population-level plasticity drives plant trait variation along elevation
Within a species, plant traits may vary substantially along environmental gradients. However, is such variation (1) consistent across locations and (2) genetic or non-genetic (i.e., plastic) in nature? In a recent...

Gene flow in mountain environments
Responses of high-mountain plant species to global change are highly influenced by the genetic background of the species, including genetic diversity or gene flow between populations. García-Fernández et al. study the...

Heritability of interactive pollen–pistil traits
In Collinsia heterophylla, a mixed-mating species with delayed stigma receptivity, there is a potential for a sexual conflict over timing of stigma receptivity. Madjidian et al. use experimental crosses and perform...
Phylogeographic patterns of Epipactis lineages
Phylogeographic patterns of <i>Epipactis</i> lineages Epipactis is a widespread orchid genus encompassing morphologically and genetically problematic aggregates of taxa, such as the E. helleborine species...
