Understanding how certain receptors affect the glowing of red tide algae

Official title: The Role of G Protein-coupled Receptors in Red Tide Dinoflagellate Bioluminescence

Funded at University of South Florida · NIH-10708533 · Data updated 2026-11-12

This study is looking at how certain receptors in a type of glowing algae called Lingulodinium polyedra help it light up, especially during red tide events, and it aims to find out how things like ocean waves and predators affect this glowing ability, which could help us understand the impact of red tides on coastal areas.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals living in coastal areas affected by red tide blooms or those who consume seafood from these regions.

Less likely to help

Patients who do not live near coastal areas or do not consume seafood are unlikely to benefit from this research.

What this research studies

This research investigates the role of G protein-coupled receptors (GPCRs) in the bioluminescence of dinoflagellates, specifically focusing on the species Lingulodinium polyedra, which is known for causing red tide events. The study aims to understand how these receptors contribute to the algae's ability to glow, which may be influenced by environmental factors like wave turbulence and predator behavior. By using advanced techniques such as anti-sense DNA oligonucleotide knockdown experiments, researchers will identify specific receptors involved in this bioluminescent signaling pathway. This work could provide insights into the ecological impacts of red tides and their effects on coastal communities.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and management of red tide events, potentially reducing their harmful effects on coastal ecosystems and human health.

How similar studies have gone: While the specific focus on GPCRs in dinoflagellate bioluminescence is novel, related research on GPCRs in other biological contexts has shown promising results.
