Chemoreception in Nematodes
Chemical signals from the environment are the most important sensory inputs for nematodes. The ability to receive and interpret chemical signals from the environment is essential for nematodes, parasitic or free living, to complete their life cycle. Chemoreceptors are needed: (i) to find food and good environmental conditions, for instance to find the host in parasitic species; (ii) to reach the host’s organs in which development can take place and to interpret signals from the host that trigger important developmental switches; (iii) to avoid predators and dangerous or toxic chemicals; (iv) to interpret signals from other individuals of the species that signal crowding; (v) to find the opposite sex for reproduction. If better understood at the cellular and molecular level, chemoreception would have enormous potential as a target for the control of nematodes.
