The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).

The series of molecular signals generated as a consequence of a G protein-coupled receptor binding to its physiological ligand, followed by activation of guanylyl cyclase (GC) activity and a subsequent increase in the concentration of cyclic GMP (cGMP).

The sequence of reactions within a cell required to convert absorbed photons into a molecular signal.

The directed movement of a motile cell or organism in response to environmental oxygen.

Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

Any process that decreases the rate, frequency or extent of cGMP-mediated signaling. cGMP-mediated signaling is a series of molecular signals in which a cell uses cyclic GMP to convert an extracellular signal into a response.

Any process that modulates the rate, direction or extent of axon extension.

Feeding behavior in a larval (immature) organism.

Behavior that is dependent upon the sensation of temperature.

Any process that modulates the frequency, rate or extent of neuron differentiation.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

The process in which the anatomical structures of a neuron projection are generated and organized. A neuron projection is any process extending from a neural cell, such as axons or dendrites.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating increased oxygen tension.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus reflecting the presence, absence, or concentration of oxygen.

The process in which a cation is transported across a membrane.

Any process that modulates the frequency, rate or extent of eating behavior.

An ion channel complex through which cations pass.

A cilium which may have a variable array of axonemal microtubules but does not contain molecular motors.
