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.

Identification of two classes of mouse vomeronasal receptors for female pheromone cues suggests distinct gating mechanisms in pheromone-triggered reproductive behaviors.

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.

The activation of Drosophila Or7a receptors guides aggregation and egg-laying behaviors towards both green leaf volatiles and a male-specific food-odor-induced pheromone.

Male C. elegans die through two distinct mechanisms – mating-induced germline activation, and potent male pheromone toxicity – but the latter is unique to males of androdioecious species (made up of hermaphrodites and males).

Differing from its ortholog in Helicoverpa armigera, pheromone receptor HassOr14b is tuned to the major sex pheromone component in H. assulta, and two amino acids in the intracellular domain determine their ligand selectivity.

In moths, male receptors tuned to type I female pheromones may not have a monophyletic origin.

The cellular and molecular substrates that underlie the programmed behavioral response to a gustatory sex pheromone have been identified.

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.

In response to starvation, C. elegans converts a favorable pheromone that induces aggregation to an unfavorable one that induces a stress-resistant larval stage, thereby altering its chemical message without having to synthesize new pheromones de novo.
