    Cytoplasmic retention and degradation of a mitotic inducer enable plant infection by a pathogenic fungus

    Paola Bardetti et al.
    Degradation of a mitotic inducer coordinates the transition of two successive cell cycle arrests during the infective process of a plant pathogenic fungus.

    A host beetle pheromone regulates development and behavior in the nematode Pristionchus pacificus

    Jessica K Cinkornpumin et al.
    A lipid-binding protein mediates both attraction and hypersensitivity to a beetle sex pheromone in a specific type of nematode-insect relationship known as necromeny.

    Male pheromones modulate synaptic transmission at the C. elegans neuromuscular junction in a sexually dimorphic manner

    Kang-Ying Qian et al.
    Male pheromone environment increases the cholinergic synaptic transmission at the neuromuscular junction in Caenorhabditis elegans hermaphrodites during development, decreasing hermaphrodites' locomotion activity and promoting mating efficiency.

    Regulatory changes in two chemoreceptor genes contribute to a Caenorhabditis elegans QTL for foraging behavior

    Joshua S Greene et al.
    A quantitative trait locus that includes two pheromone receptor genes affects foraging behavior; for one of the genes, the two alleles of the QTL have opposite effects because of distinct sites of expression.

    Evolved differences in larval social behavior mediated by novel pheromones

    Joshua D Mast et al.
    A novel pheromone/receptor neuron pair mediates attraction between Drosophila larvae, and evolved differences in pheromone signaling underlie changes in social behavior between drosophilid species.

    An alternatively spliced, non-signaling insulin receptor modulates insulin sensitivity via insulin peptide sequestration in C. elegans

    Bryan A Martinez et al.
    A truncated, non-signaling insulin receptor regulates insulin sensitivity in the nematode C. elegans by sequestering insulin peptides and preventing their interaction with full length receptors.

    Feeding state-dependent regulation of developmental plasticity via CaMKI and neuroendocrine signaling

    Scott J Neal et al.
    CaMKI and neuroendocrine signaling integrate information about food status to regulate a developmental decision in C. elegans.

    Subtle selectivity in a pheromone sensor triumvirate desynchronizes competence and predation in a human gut commensal

    Johann Mignolet et al.
    A new cell–cell communication system in Streptococcus salivarius, a human gut commensal, discriminates between close signaling molecules to specifically produce bacteriocin-based antimicrobials and disconnects it from foreign DNA acquisition.

    A resource for the Drosophila antennal lobe provided by the connectome of glomerulus VA1v

    Jane Anne Horne et al.
    FIB-SEM is used to identify comprehensively and reconstruct 192 neurons and their complete connectome for glomerulus VA1v of the Drosophila antennal lobe, in particular to reconstruct its local interneurons.

    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.
