ammonium chloride chemotaxis defective

Failure in directed movement in response to ammonium chloride compared to control. In C. elegans, NH4Cl is an attractant. NH4Cl has also subsequently been used to assay for Cl- attraction in C. elegans.

ammonium chloride chemotaxis variant

Any variation in the directed movement of a worm in response to a specific concentration gradient of ammonium chloride. In C. elegans, at specific concentrations, ammonium chloride is an attractant. NH4Cl has also been used to assay for Cl- attraction.
