Sentences with phrase «odorant receptors»

The study «A long - range cis - regulatory element for class I odorant receptor genes» published in Nature Communications was a collaborative effort between Tokyo Tech, the University of Tokyo, Nihon BioData Corporation and RIKEN Brain Science Institute.

«We were quite surprised that by silencing just this single odorant receptor, flies could no longer localize their preferred egg - laying substrate.»

However, the researchers did not find any evidence for an olfactory system which is based on odorant receptors in the most basal insect, the jumping bristletail.

Turin's more controversial theory, put forth in 1996 and now the subject of two popular books, holds instead that odorant receptors sense the way a molecule's atoms jiggle.

Zwiebel and colleagues scanned the mosquito genome looking for genes similar to those that generate fruit fly odorant receptors, proteins that project from nerve cells and initiate a biochemical cascade when they encounter certain molecules in the air.

In vivo calcium imaging of the flies» brains stimulated with citrus enabled the researchers to identify the corresponding odorant receptor.

The sensors, called odorant receptors, are so sensitive to the chemical makeup of incoming odors that just a slight difference turns a smell from sweet to rancid.

«The first insects were not yet able to smell well: Odorant receptors evolved long after insects migrated from water to land.»

Important advances have included the discovery of the first evidence that the odour response is governed by neurons, of the intracellular signalling pathways between odorant receptors and sensory neurons, and of specific neurons, receptors and neurotransmitters involved in behaviour adaption following experience.

In C. elegans, as in other animals, odors are detected by G protein coupled odorant receptors on specialized sensory neurons.

Bargmann provided the first evidence showing that the type of odor response in C. elegans — attraction or repulsion - was governed not by the specific odorant receptor, but by the neuron expressing it.

With similar precision, Professor Bargmann has also identified many of the intracellular signalling pathways in C. elegans that relay information from cell surface odorant receptors (G protein - coupled receptors) to the interior of each sensory neuron.

This preference is controlled by one single odorant receptor.

In the case of β - ionone, the smell associated with violets, McRae and colleagues managed to pinpoint the exact mutation (a change in the DNA sequence) in the odorant receptor gene OR5A1 that underlies the sensitivity to smell the compound and to perceive it as a floral note — people who are less good at smelling β - ionone also describe the smell differently, as sour or pungent, and are less likely to find it pleasant.

The odorant receptor molecules sit on the surface of sensory nerve cells in our nose.

Christine Mißbach, first author of the study, analyzed the active genes in the insect antennae where the olfactory receptors are located and describes her discovery this way: «Astonishingly, the firebrat, which is more closely related to flying insects, employs several co-receptors, while the odorant receptors themselves are absent.»

Each odor - detecting neuron (referred to as olfactory sensory neuron from here on), chooses a single odorant receptor gene from a fairly large number of options that are split into class I (fish - like) and class II (terrestrial - specific) odorant receptors.

C. elegans has the ability to distinguish between hundreds of different odors due to a range of molecules — odorant receptors — on the surface of a cluster of neurons at the tip of its head.

The odorant receptor - dependent role of olfactory marker protein in olfactory receptor neurons.

Genetic variation in the odorant receptor OR2J3 is associated with the ability to detect the «grassy» smelling odor, cis -3-hexen-1-ol.

Detection of pup odors by non-canonical adult vomeronasal neurons expressing an odorant receptor gene is influenced by sex and parenting status.
