C. elegans chemotaxis assay - PubMed
2013年4月27日 · Caenorhabditis elegans has impressive chemotaxis behavior. The premise behind testing the response of the worms to an odorant is to place them in an area and observe the movement evoked in response to an odorant.
The Behavioral Mechanism of Chemotaxis and Thermotaxis - C. elegans …
Experiments with tethered animals indicate that C. elegans can directly sense temporal changes in chemical concentration (Dusenbery 1980b). Individual animals were tethered and exposed to different concentrations of chemicals, and their responses were monitored by videotaping.
From Odors to Behaviors in Caenorhabditis elegans
ODR-10, a member of the str superfamily, was identified in a classical genetic screen for animals defective for chemotaxis toward the volatile attractant diacetyl, and remains the only functionally defined C. elegans olfactory receptor with a defined ligand (Sengupta et al. 1996) (Figure 1.5B).
Chemosensation in C. elegans - WormBook
Chemosensory cues can elicit chemotaxis, rapid avoidance, changes in overall motility, and entry into and exit from the alternative dauer developmental stage. These behaviors are regulated primarily by the amphid chemosensory organs, which …
A high-throughput behavioral screening platform for measuring chemotaxis …
2024年6月27日 · This study establishes that C. elegans is an effective discovery engine for determining chemotaxis valence and for identifying natural products detected by the chemosensory nervous system.
The Signaling Pathway of Caenorhabditis elegans Mediates Chemotaxis …
It is well known that C. elegans has chemotaxis to a variety of volatile compounds, which can mainly be mediated by the olfactory neurons. The olfactory responses for the different odors are associated with the most powerful behaviors in worms, …
Overview of Chemotaxis Behavior Assays in Caenorhabditis elegans
This overview provides a summary and general comparison of methods used to measure chemotaxis behavior in C. elegans, with the aim of helping researchers select the most suitable approach in their chemotaxis studies.

Step-Response Analysis of Chemotaxis in Caenorhabditis elegans
2005年3月30日 · Chemotaxis in C. elegans is studied in two main types of gradients: steep gradients with step-like concentration borders (Jansen et al., 2002) and shallow gradients formed by radial diffusion from a point bolus of attractant (Ward, 1973).
The Signaling Pathway of Caenorhabditis elegans Mediates Chemotaxis …
2016年5月31日 · The genome of C. elegans encodes 21 Gα subunits that play an activate role in the G protein signaling cascades, and therefore we tested the changes of chemotaxis to 2-heptanone with the 21 Gα gene mutations.
