Measurements of specialized metabolites across a population of 800 natural Arabidopsis thaliana accessions revealed different pressures and evolutionary processes that shaped their variation and distribution across Europe.
A novel dimethylsulfoniopropionate lyase was identified, which catalyzes dimethyl sulfide releasing by a new mechanism and is found in several bacterial lineages, revealing its important roles in global sulfur cycling.
Inbreeding compromises floral traits and reduces pollinator visitation rates disproportionally in female relative to male individuals in a dioecious plant and may thus interfere with the equilibrium of a complex co-evolutionary plant-insect relationship.
The widespread occurrence of metabolically active streptomycetes in Odontotaenius disjunctus beetle frass may insulate their galleries against pathogenic fungal invasion through the production of diverse antimicrobial specialized metabolites.
In a drug choice setting, rats’ preference is initially driven by deliberative processes but shifts to more automatic selection processes after extended training, in accordance with the sequential choice model.
