A genetic analysis reveals that some olfactory sensilla of Drosophila do not require an abundant odorant binding protein and that one such protein may act in gain control.

An integrative approach is used to identify a mechanism by which the fitness effects of Y chromosomes can manifest via trans effects on autosomal genes, through their effects on male courtship and other sexually selected traits.

Insect symbiotic bacteria regulate expression of an odorant binding protein that mediates an evolutionarily conserved hematopoietic pathway crucial for host immune system development and function.

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

Although odorant binding proteins are widely believed to be required for transport of odorants to receptors, six types of sensilla of Drosophila respond robustly in their absence to many odor stimuli.

A functional genetics approach reveals a novel role for odorant binding proteins in post-mating processes, with complex mechanisms of evolutionary change across closely related insect species.

Hygroreception, a poorly understood process critical to insect survival, depends on a small protein in the antenna of the fruit fly that was previously thought to transport odorants.

Computational and theoretical analyses offer novel and unexpected insight into how complex, naturally occurring odor mixtures are parsed and normalized at the very first stage of olfaction.

The development of the tsetse fly immune system relies on a cue from an endosymbiotic bacterium called Wigglesworthia.

The southern house mosquito senses the oviposition attractants skatole and indole with two receptor proteins sharing only 50% amino acid identity, and having the residues alanine-73 and leucine-74 in the skatole and indole receptors, respectively, control their specificity.
