Chemosensation in Holothruoids

Project description

Chemical-based communication in sea cucumbers

Organisms detect and respond to chemical signals in their environment through chemosensation. This sensory mechanism involves specialised receptors that interact with specific chemicals in the surroundings and is responsible for driving behaviours such as foraging and reproduction. With the support of the Marie Skłodowska-Curie Actions programme, the SensHolo project will focus on chemosensation in sea cucumbers. The research team will employ a multidisciplinary approach to identify chemosensory receptors in sea cucumbers and their activation mechanisms and physiology. SensHolo will advance knowledge of chemical communication in sea cucumbers, with potential impacts on both marine biology and aquaculture practices.

Objective

Chemosensation is a critical signalling process for sea cucumbers which relies on the interaction between their chemosensory receptors and various ligands for foraging and reproduction. Although there is a vast amount of research on the chemistry of secreted specialized metabolites of sea cucumbers, and some behavioural data evidencing chemoreception of these metabolites, the chemosensory receptors of these organisms have not yet been identified and nothing is known about the physiology behind sea cucumber chemosensation. This setback is in large part because the scientific approach behind studying chemosensation requires a vast array of techniques and expertise in ethology, chemistry, molecular biology, and biophysics.
Firstly, a behaviour associated with a chemical cue must be quantifiable, secondly, the precise chemical cue eliciting the behaviour response must be identified and isolated, thirdly, the chemosensory receptor of this specific cue needs to be identified on a tissue, cellular, and molecular level, and finally, the activation of this specific receptor by a specific chemical cue must elicit a measurable response on a molecular, cellular, tissue, and organismal level.
Through this project, I will elucidate the physiology of chemical communication between sea cucumber by considering these sequential steps in chemosensation. With my previous experience in sea cucumber ethology and chemistry, SensHolo will enrich my skill base in molecular biology and biophysics so that the mechanisms behind intraspecific chemical communication between sea cucumbers may be determined from both the emitter and receiver perspective; from signal to receptor.
This holistic approach will be ground-breaking in chemosensation and sea cucumber research. It will enable future research to address the evolution of chemosensation in marine invertebrates and the chemical ecology of sea cucumbers both in the context of optimizing aquaculture and in their ecological conservation.
