    Cytokinin transfer by a free-living mirid to Nicotiana attenuata recapitulates a strategy of endophytic insects

    Christoph Brütting et al.
    Cytokinin-dependent manipulation of plant metabolism is a strategy employed not only by gallers and leaf-miners but also by a free-living insect, Tupiocoris notatus, which directly transfers cytokinins at feeding sites to manipulate its host plant.

    Plant defense phenotypes determine the consequences of volatile emission for individuals and neighbors

    Meredith C Schuman et al.
    Both the frequency of sesquiterpene-emitting individuals and the defense capacity of individual plants determine the consequences of sesquiterpene volatile emission for individuals and their neighbors in populations of the wild tobacco Nicotiana attenuata.

    Blumenols as shoot markers of root symbiosis with arbuscular mycorrhizal fungi

    Ming Wang et al.
    Arbuscular mycorrhizal fungi-induced hydroxy- and carboxyblumenol C glycosides accumulate in plant shoots and allow for facile high-throughput screening for functional plant-AMF associations.

    Benefits of jasmonate-dependent defenses against vertebrate herbivores in nature

    Ricardo AR Machado et al.
    Uncovering an link between plant defense signaling and vertebrate feeding behavior suggests that large browsers may exert strong selection pressure on jasmonate-dependent secondary metabolites.

    How scent and nectar influence floral antagonists and mutualists

    Danny Kessler et al.
    Floral scent and nectar are highly variable in natural populations and both traits can influence outcrossing rates differently for different pollinators and increase future herbivory.

    Hawkmoths evaluate scenting flowers with the tip of their proboscis

    Alexander Haverkamp et al.
    Building on previous work (Kessler et al., 2015), it is shown that long-tongued hawkmoths assess individual flowers by smelling floral odors with olfactory neurons on their proboscises, and that this close-range perception is crucial for successful pollination and foraging.

    Point of View: Predictive regulation and human design

    Peter Sterling
    Why does the human regulatory system, which evolution tuned for small satisfactions, now constantly demand 'more'?

    Antimicrobial peptide expression in a wild tobacco plant reveals the limits of host-microbe-manipulations in the field

    Arne Weinhold et al.
    The attempt to manipulate a microbiome in planta to study the ecological consequences under field conditions leaves plants and their microbes surprisingly unimpressed.
