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

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.

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.

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.

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).

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.

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.

Unexpected structural diversity of nematode small molecules, as revealed by high-resolution phylogenetic analysis, suggests recurrent biochemical innovation, a pattern that is probably typical across animals.

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

A fatty acyl reductase gene family expansion in the Hymenoptera crown group led to recruitment of novel pheromone-biosynthetic enzymes and is linked to evolution of pheromone marking behavior.
