Simulations and experiments on systems containing two different populations of microorganisms show that interactions that benefit at least one of the populations can lead to communities with stable compositions, and that strong cooperation between two populations can lead to communities in which both populations are mixed together.

The use of tissue culture reduces the chemical modification of plant DNA, and this has lasting effects on gene expression in the plants and their descendants.

The ability of Manduca moths to recognize changes in the profile of volatile compounds released by plants being attacked by Manduca caterpillars allows them to lay their eggs on plants that are less likely to be attacked by insects and other predators, and to avoid competing against other caterpillars of the same species for resources.

A fungal effector secreted by the corn smut pathogen increases the virulence of the pathogen by elevating anthocyanin production and reducing lignification in maize.

Fluorescent sensors can track the movement and distribution of the plant hormone abscisic acid in roots and leaves in Arabidopsis.

Malaria 'hotspots' can be identified that range in size from a few homesteads to a village, and it will be necessary to eliminate hotspots at varying scales as we progress towards eliminating malaria.

SAK1, a novel cytoplasmic phosphoprotein, is a key intermediate component of the retrograde signaling pathway controlling nuclear gene expression during acclimation of Chlamydomonas cells to singlet oxygen stress.

Structure-function analyses reveal the mechanistic underpinnings of inside-out transmembrane signaling that controls periplasmic proteolysis, and thereby biofilm formation, in bacteria and may be relevant in the context of other signaling proteins with similar control elements.

Loss-of-heterozygosity mutations, but not aneuploidies, are linked to the evolution of drug resistance in Candida albicans isolated from immunocompromised patients.

Research in molecular ecology and evolution is increasingly utilizing the model plant Arabidopsis thaliana, placing a spotlight on its natural history.
