Molecular Mechanisms of Chemotaxis to Sodium Chloride in Caenorhabditis elegans

Cells and organisms use chemotaxis to navigate through their environment. We used the nematode Caenorhabditis elegans and its chemotaxis response to NaCl to study three aspects of this behavior: regulation of protein localization in a primary cilium and its function, bistable genetic switch stability in neuronal cell fate maintenance, and gene expression variation underlying behavioral variability.
