When grown at a temperature from 16 degrees to 25 degrees and placed on a thermal gradient, the nematode Caenorhabditis elegans migrates to its growth temperature and then moves isothermally. Behavioral adaptation to a new temperature takes several hours. Starved animals, in contrast, disperse from the growth temperature. Several mutants selected for chemotaxis defects have thermotaxis defects as well; these behaviors depend on some common gene products. New mutants selected directly for… Expand
Thermal limits and chemotaxis in mutants of the nematodeCaenorhabditis elegans defective in thermotaxis
It is concluded that thermotaxis shares specific gene requirements with processes controlling both thermal limits and sensory reception in nematode Caenorhabditis elegans. Expand
A steep thermal gradient thermotaxis assay for the nematode Caenorhabditis elegans
A short linear thermal gradient assay is presented which is faster and which allows statistical evaluation of different populations using a thermotaxis index and uses inexpensive materials so that multiple tests can be performed in parallel in a short period of time. Expand
Neural regulation of thermotaxis in Caenorhabditis elegans
A neural model is proposed in which regulation of the activities of the two interneurons in opposite directions, depending on the cultivation temperature, is essential for thermotaxis, and an amphid sensory neuron, AFD, is a major thermosensory neuron. Expand
Modulation of Caenorhabditis elegans chemotaxis by cultivation and assay temperatures
The results indicate the important role of multi-sensory integration of chemosensory and thermosensory information in chemotaxis behavior of the C. elegans. Expand
Chemotactic behavior of mutants of the nematode Caenorhabditis elegans that are defective in their attraction to NaCl
Wild-type C. elegans and 16 derivative strains previously selected for defective attraction to NaCl and shown to carry single-gene mutations were tested for their responses to nine chemical stimuli, indicating that there are probably at least four different receptors. Expand
Temperature-sensitive mutations causing reversible paralysis in Caenorhabditis elegans.
A method has been developed for the isolation of temperature-dependent paralytic mutants of the nematode Caenorhabditis elegans, based on a screening procedure using short-time exposure to 30 degrees C, and one mutation, designated mah-2, is a sex-linked semidominant that is mapped as 0.6 map units left of dpy-6.

Genetic Control of Temperature Preference in the Nematode Caenorhabditis elegans
It is shown here that feeding-state-dependent modulation of thermotaxis is a powerful behavioral paradigm for elucidating the mechanism underlying neural plasticity, learning, and memory in higher animals. Expand
The extraordinary AFD thermosensor of C. elegans
The contributions of AFD to thermosensory behaviors and temperature-dependent regulation of organismal physiology and the mechanisms that enable this neuron type to adapt to recent temperature experience and to exhibit extraordinary thermosensitivity over a wide dynamic range are described. Expand
Distribution and movement of Caenorhabditis elegans on a thermal gradient
The results favor a model for thermal response of C. elegans that postulates a single drive based on warm sensation rather than downward and upward drives in the physiological temperature range. Expand
The life cycle of the nematode Caenorhabditis elegans. I. Wild-type growth and reproduction.
Comparable measurements at 16 and 25°C establish that these are acceptable limit temperatures for work with temperature-sensitive mutants, although egg yield is somewhat reduced and the kinetics of egg-laying are altered at 25 °C. Expand
