The directed movement of a motile cell or organism towards a lower concentration of a specific chemical on, within or near a second organism, where the two organisms are in a symbiotic interaction. The directed movement of a motile cell or organism in response to an external stimulus. The directed movement of a motile cell or organism, or the directed growth of a cell guided by a lower concentration, in a concentration gradient of a specific chemical. The creation and reception of signals that repel a precerebellar neuron as a component of the process of tangential migration. The creation and reception of signals that result in the movement of interneurons away from the signal during migration from the subpallium to the cortex. 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 chemical stimulus. The creation and reception of signals that repel olfactory bulb interneurons from the subventricular zone as a component process in tangential migration. The directed movement of a germ cell from their site of production to the gonad, through the repulsion of cells away from a tissue. The creation and reception of signals that guide olfactory bulb interneurons down concentration gradients towards the olfactory bulb. Any process that stops, prevents or reduces the frequency, rate or extent of the directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical. The process by which a branchiomotor neuron growth cone is directed to a specific target site in response to a repulsive chemical cue. Branchiomotor neurons are located in the hindbrain and innervate branchial arch-derived muscles that control jaw movements, facial expression, the larynx, and the pharynx. Any process that activates or increases the frequency, rate or extent of the directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical. Any process that modulates the frequency, rate or extent of the directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical. 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 directed movement of a motile cell or organism towards a lower concentration of environmental oxygen. The process by which a neuronal cell in a multicellular organism recognizes chemorepellent signals that inhibit its growth toward the source.
