Behavioural and physiological stress response components are integrated on the major axis of genetic covariation, with implications for health and the understanding of the evolutionary response to stressors.

Variation in patterns of floral UV pigmentation is controlled by a single transcription factor in sunflower and affects both pollinator attraction and responses to environmental stresses.

The activation of transposable elements and relaxed purifying selection underpin an incipient expansion of the genome in populations of a major wheat pathogen.

This microscale cultivation strategy will help in the discovery of novel bacterial species and their prioritization for antibiotic screening campaigns.

Gut microbial signatures of domestication parallel those of industrialization, implicating shared ecological drivers.

An investigation of transposable element evolution in a group of long-term asexual animals shows that many of the predicted effects of asexuality are not observed.

Evolution strictly preserves telomere stability but rapidly diversifies telomere length regulation in Drosophila.

Heritable variation in the benefit maize plants receive from arbuscular mycorrhizal fungi supports the feasibility of breeding crops to optimize use of this ancient symbiosis.

A systematic experimental comparison of prosocial behavior in eight corvid species reveals sex-specific effects of cooperative breeding and colonial nesting, thereby adding important new insights regarding the evolution of prosociality.

A family of homing genetic elements that look like inteins but work differently is the progenitor of the endonuclease that enables Saccharomyces cerevisiae to change its mating type.
