Olfaction is an ancient sensory system allowing an organism to detect chemicals in its environment. The first step in odor transduction is mediated by binding odorants to olfactory receptors (ORs) which belong to the heptahelical G-protein-coupled receptor (GPCR) superfamily. Mammalian ORs are disposed in clusters on virtually all chromosomes. They are encoded by the largest multigene family (∼1000 members) in the genome of mammals and Caenorhabditis elegans, whereas Drosophila contains only 60… 
The Olfactory Nervous System Of Terrestrial And Aquatic Vertebrates
TLDR
The molecular age in olfaction initiated in 1991 with the significant discovery of a large, multigene family of olfactory receptors in rat by Linda Buck and Richard Axel and opened the way to characterize the gene families of o aroma receptors through exhaustive computational data mining in different species genome as well as by in vitro biology.
Physiology of rodent olfactory bulb interneurons
TLDR
The theoretical prediction of active computation within single spines in the granule cell gemmule physiology during local glutamatergic activation is confirmed, emphasizing the functional importance of morphological compartmentalization for the cell’s physiology.
Evolution of avian olfaction
TLDR
The estimated OR gene repertoire sizes, and the proportion of presumably functional OR genes, strongly suggest that avian olfactory ability is well developed and much more important than previously thought.
Biomimetic integrated olfactory sensory and olfactory bulb systems in vitro based on a chip.
TLDR
A biomimetic integrated olfactory sensory and processing system can serve as a novel model for studying the physiological and pathological mechanisms of olfaction, and the pharmacological application in vitro.
Multiple olfactory pathways contribute to the lure process of Caenorhabditis elegans by pathogenic bacteria.
TLDR
This work further clarifies the distinct olfactory signaling pathways through which Caenorhabditis elegans senses different chemicals and is lured by B. nematocida B16, improving the comprehensive understanding of the mechanisms by which bacterial pathogens effectively infect their hosts.
Computerized screening of G-protein coupled receptors to identify and characterize olfactory receptors
TLDR
Developing computerized programs to differentiate ORs from GPCRs indicates that this novel method may be considered as a tool for identification and characterization of receptors which might aid in therapeutic approaches to human chemical-mediated sensitization.
The teleost taar family of olfactory receptors: From rapidly evolving receptor genes to ligand-induced behavior
TLDR
The taar gene family has been delineated in jawless, cartilaginous, and bony fish and it is concluded that the taar genes are evolutionary much younger than the related OR and ORA/V1R olfactory receptor families, which are present already in lamprey, a jawless vertebrate.
Recent concepts about sense of smell, odorant receptors and physiology of olfaction- an insight
TLDR
This review discusses the recent advancements regarding the chemical nature of human olfactory receptors, mechanism ofOlfactory transduction, nomenclature and families of olfaction receptors, Olfactory coding, smell discrimination in different animals and ofactory memory.
Ovarian odorant-like biomolecules in promoting chemotaxis behavior of spermatozoa olfactory receptors during migration, maturation, and fertilization
Studies have shown that olfactory receptor genes are the largest in the human genome, which are significantly expressed in olfactory and non-olfactory tissues such as the reproductive systems where
REVIEW ARTICLE: RECENT CONCEPTS ABOUT SENSE OF SMELL, ODORANT RECEPTORS AND PHYSIOLOGY OF OLFACTION- AN INSIGHT
The sense of olfaction reached its zenith in development much earlier than other special senses. Olfaction is much more acute than the other senses, exhibits both high sensitivity for odours and high

Minigenes Impart Odorant Receptor-Specific Axon Guidance in the Olfactory Bulb
TLDR
An olfactory sensory neuron expresses selectively one member from a repertoire of approximately 1000 odorant receptor (OR) genes and projects its axon to a specific glomerulus in the Olfactory bulb, recapitulated by MOR23 and M71 OR minigenes, introduced into mice.
Molecular Bases of Odor Discrimination: Reconstitution of Olfactory Receptors that Recognize Overlapping Sets of Odorants
TLDR
The present study uses Ca2+ imaging and single-cell reverse transcription-PCR techniques to identify mouse olfactory neurons responding to an odorant and subsequently to clone a receptor gene from the responsive cell, providing direct evidence for the existence of a receptor code.

TLDR
The identification of a large multi-gene family of candidate Drosophila odorant receptors suggests that, as in other animals, a multitude of distinct odorants is recognized by a diversity of ligand-binding receptors.
A novel family of genes encoding putative pheromone receptors in mammals
TLDR
Sequence analysis indicates that a family of about 30 putative receptor genes comprise a novel family of seven transmembrane domain proteins unrelated to the receptors expressed in the MOE, likely to encode mammalian pheromone receptors.
A Spatial Map of Olfactory Receptor Expression in the Drosophila Antenna
TLDR
A novel family of seven transmembrane domain proteins, encoded by 100 to 200 genes, that is likely to represent the family of Drosophila odorant receptors are identified and may ultimately afford a system to understand the mechanistic link between odor recognition and behavior.

TLDR
The odorant receptor-mediated signal transduction appears to be reconstituted by this two-step approach: the receptor screening for given odorant(s) from single neurons and the functional expression of the receptor via recombinant adenovirus.
Odorant Receptor Expression Defines Functional Units in the Mouse Olfactory System
TLDR
The data provide evidence that ORs determine both odorant specificity and axonal convergence and thus direct functionally similar afferents to form particular glomeruli and confirm and extend the notion that OR expression provides a molecular basis for the formation and arrangement of glomerular functional units.
Olfaction and Odor Discrimination Are Mediated by the C. elegans Guanylyl Cyclase ODR-1
TLDR
It is demonstrated that the transmembrane guanylyl cyclase ODR-1 is essential for responses to all AWC-sensed odorants, and proposed that AWC odorant signaling pathways are insulated to permit odor discrimination.
Spatial segregation of odorant receptor expression in the mammalian olfactory epithelium
TLDR
The patterns of odorant receptor expression in the rat olfactory epithelium are examined to determine whether the mammalian olfaction system employs spatial segregation of sensory input to encode the identity of an odorant stimulus.
Reprogramming Chemotaxis Responses: Sensory Neurons Define Olfactory Preferences in C. elegans
TLDR
An animal's preference for an odor is defined by the sensory neurons that express a given odorant receptor molecule, which is normally expressed in the AWA olfactory neurons.
