Any process that increases the rate, frequency or extent of nitric oxide mediated signal transduction. Nitric oxide mediated signal transduction is a series of molecular signals mediated by the detection of nitric oxide (NO).

The series of molecular signals generated as a consequence of excitation of rhodopsin by a photon and the events that convert the absorbed photons into a cellular response.

The directed movement of a cell or organism towards a source of light.

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 chemical reactions and pathways resulting in the formation of cyclic GMP, guanosine 3',5'-phosphate.

The chemical reactions and pathways resulting in the formation of cyclic GMP, guanosine 3',5'-phosphate.

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.

Any intracellular signal transduction in which the signal is passed on within the cell via nitric oxide (NO). Includes synthesis of nitric oxide, receptors/sensors for nitric oxide (such as soluble guanylyl cyclase/sGC) and downstream effectors that further transmit the signal within the cell. Nitric oxide transmits its downstream effects through either cyclic GMP (cGMP)-dependent or independent mechanisms.

Behavior associated with the intake of food.

Behavior that is dependent upon the sensation of chemicals.

Behavior that is dependent upon the sensation of chemicals.

The flow of blood through the body of an animal, enabling the transport of nutrients to the tissues and the removal of waste products.

Any process that modulates the force with which blood travels through the circulatory system. The process is controlled by a balance of processes that increase pressure and decrease pressure.

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

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 herbicide stimulus. Herbicides are chemicals used to kill or control the growth of plants.

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 an organic cyclic compound stimulus.

Any intracellular signal transduction in which the signal is passed on within the cell via cyclic GMP (cGMP). Includes production of cGMP, and downstream effectors that further transmit the signal within the cell.

Reactions triggered in response to the presence of a Gram-negative bacterium that act to protect the cell or organism.

The series of events required to receive a bitter taste stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process.

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 nitric oxide produced as part of the defense response of the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.

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.

A negative regulation of smooth muscle contraction resulting in relaxation of vascular smooth muscle. The relaxation is mediated by a decrease in the phosphorylation state of myosin light chain. This can be achieved by removal of calcium from the cytoplasm to the sarcoplasmic reticulum lumen through the action of Ca2+ ATPases leading to a decrease myosin light chain kinase activity, and through calcium-independent pathways leading to a increase in myosin light chain phosphatase activity.

The immediate defensive reaction by vertebrate tissue to injury caused by chemical or physical agents.

Modulation of synaptic transmission by cell-cell signaling from postsynapse to presynapse, across the synaptic cleft, mediated by nitric oxide.

Modulation of synaptic transmission by cell-cell signaling from postsynapse to presynapse, across the synaptic cleft, mediated by nitric oxide.

Complex that possesses guanylate cyclase activity and is not bound to a membrane.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

Complex that possesses guanylate cyclase activity and is not bound to a membrane.

A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.

The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.

Complex that possesses guanylate cyclase activity and is not bound to a membrane.

A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.
