    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.

    Feeding-induced rearrangement of green leaf volatiles reduces moth oviposition

    Silke Allmann et al.
    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.

    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.

    Allosteric activation of the nitric oxide receptor soluble guanylate cyclase mapped by cryo-electron microscopy

    Benjamin G Horst et al.
    The full-length structures of the mammalian nitric oxide receptor reveal the molecular activation steps and a binding site for the prototype of FDA-approved stimulators.

    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.

    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.
