Requirement for Slit-1 and Robo-2 in zonal segregation of olfactory sensory neuron axons in the main olfactory bulb [PDF]

, 2007
The formation of precise stereotypic connections in sensory systems is critical for the ability to detect and process signals from the environment. In the olfactory system, olfactory sensory neurons (OSNs) project axons to spatially defined glomeruli ...

Chemosensory Gene Families in Ectropis grisescens and Candidates for Detection of Type-II Sex Pheromones

Frontiers in Physiology, 2017
Tea grey geometrid (Ectropis grisescens), a devastating chewing pest in tea plantations throughout China, produces Type-II pheromone components. Little is known about the genes encoding proteins involved in the perception of Type-II sex pheromone ...

Enzymatic Basis for the Oxidative Branch of Aromatic Amino Acid Fermentation Leading to p‐cresol Formation

Advanced Science, EarlyView.
In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...

Three Odorant-binding Proteins from Rabbit Nasal Mucosa [PDF]

Chemical Senses, 1997
Following the purification of an odorant-binding protein (OBP) from rabbit nasal mucosa, we have identified, purified and partially characterized two additional OBPs from the nasal tissue of the same animal species. OBP-II is a monomer of 21 kDa and isoelectric point 4.2; OBP-III is a dimer with subunits of 23 kDa and isoelectric point 4.8. Like OBP-I,

Association of Putative Members to Family of Mosquito Odorant Binding Proteins: Scoring Scheme Using Fuzzy Functional Templates and Cys Residue Positions

Bioinformatics and Biology Insights, 2013
Proteins may be related to each other very specifically as homologous subfamilies. Proteins can also be related to diverse proteins at the super family level.

Robust olfactory responses in the absence of odorant binding proteins

eLife, 2019
Odorant binding proteins (Obps) are expressed at extremely high levels in the antennae of insects, and have long been believed essential for carrying hydrophobic odorants to odor receptors.

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

Advanced Science, EarlyView.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Differential Expression Analysis of Chemoreception Genes in the Striped Flea Beetle Phyllotreta striolata Using a Transcriptomic Approach. [PDF]

PLoS ONE, 2016
Olfactory transduction is a process by which olfactory sensory neurons (OSNs) transform odor information into neuronal electrical signals. This process begins with the binding of odor molecules to receptor proteins on olfactory receptor neuron (ORN ...

Transcriptome Analysis of Antennal Chemosensory Genes in Curculio Dieckmanni Faust. (Coleoptera: Curculionidae)

Frontiers in Physiology, 2022
The olfactory system plays a key role in regulating insect behaviors, such as locating host plants, spawning sites, and mating partners and avoiding predators. Chemosensory genes are required for olfactory recognition in insects.
