    Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

    Tobias Züst et al.
    A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

    An evolutionarily young defense metabolite influences the root growth of plants via the ancient TOR signaling pathway

    Frederikke Gro Malinovsky et al.
    Young defense metabolites are often believed to be solely outputs but evidence suggests that they can regulate ancient signaling pathways.

    A gustatory receptor tuned to the steroid plant hormone brassinolide in Plutella xylostella (Lepidoptera: Plutellidae)

    Ke Yang et al.
    The gustatory receptor PxylGr34 is tuned to the steroid plant hormone brassinolide and mediates the deterrent effects of brassinolide on feeding and ovipositing behaviors in Plutella xylostella.

    Genetic architecture of natural variation in cuticular hydrocarbon composition in Drosophila melanogaster

    Lauren M Dembeck et al.
    Genome wide association analyses in a wild-derived Drosophila melanogaster population uncover extensive variation in cuticular hydrocarbon composition, which may present a target for natural selection and adaptive evolution.

    Evolution of C4 photosynthesis predicted by constraint-based modelling

    Mary-Ann Blätke, Andrea Bräutigam
    Constraint-based modelling predicts C4 photosynthesis evolves under resource limitation from an ancestral ground state of C3 photosynthesis and attributes divergent metabolic routes in extant C4 subtypes to light.
