    A hypothesis on the capacity of plant odorant-binding proteins to bind volatile isoprenoids based on in silico evidences

    Deborah Giordano et al.
    It is hypothesized that volatile organic compounds emitted by plants after stress induction may be sensed by neighboring eavesdropping plants using odorant-binding proteins.

    Streptomyces exploration is triggered by fungal interactions and volatile signals

    Stephanie E Jones et al.
    Exploratory growth is a newly discovered mode of Streptomyces growth that it is stimulated by fungi, is pH responsive, and can be communicated to other – physically separated – streptomycetes through airborne compounds.

    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.

    Nematophagous fungus Arthrobotrys oligospora mimics olfactory cues of sex and food to lure its nematode prey

    Yen-Ping Hsueh et al.
    Genetic and behavior analyses show that Caenorhabditis nematodes are lured to the predator Arthrobotrys oligospora by olfactory mimicry of food and sex cues.

    A terpene synthase-cytochrome P450 cluster in Dictyostelium discoideum produces a novel trisnorsesquiterpene

    Xinlu Chen et al.
    The social amoeba Dictyostelium discoideum employs a terpene synthase-cytochrome P450 metabolic gene cluster to produce a novel trisnorsesquiterpene discodiene.

    Herbivory-induced volatiles function as defenses increasing fitness of the native plant Nicotiana attenuata in nature

    Meredith C Schuman et al.
    A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.

    Dopamine drives Drosophila sechellia adaptation to its toxic host

    Sofía Lavista-Llanos et al.
    The insect dopaminergic system serves an important function in the regulation of ontogenesis and early development, contributing to the evolutionary processes that limit the ecological niche of Drosophila sechellia.

    Caterpillar-induced rice volatiles provide enemy-free space for the offspring of the brown planthopper

    Xiaoyun Hu et al.
    The brown planthopper has evolved a highly adaptive oviposition strategy by exploiting caterpillar-induced plant volatiles that provide safe havens for its offspring.

    Adaptation of hydroxymethylbutenyl diphosphate reductase enables volatile isoprenoid production

    Mareike Bongers et al.
    Differences in HDR product preference present a novel mechanism in plants to control substrate availability for short- and long-chain isoprenoids.

    Nitric oxide radicals are emitted by wasp eggs to kill mold fungi

    Erhard Strohm et al.
    To protect their food and themselves against detrimental mould fungi, the eggs of a wasp species synthesize and emit remarkable amounts of gaseous nitrogen oxides that are highly effective antimicrobials.
