Transcriptome Profiling Of The Radula of Patella vulgata

The radula is a long chitinous ribbon-like proboscus containing many tiny teeth that is used by almost all molluscs for feeding. The radula is scraped across the surface to which the mollusc is attached to isolate food before it enters the esophagus. The teeth, or denticles, of the radula in the common limpet (Patella vulgata) have been shown to have the highest tensile strength of any naturally occuring material, outperforming even the high strength of spider silk (Barber et al (2015)).

Working together with researchers at the University of Portsmouth including Professor Asa Barber and Professor Darek Gorecki, we are performing transcriptional profiling throughout the development of the radula to understand the gene pathways involved in the natural generation of this incredibly strong biomaterial.
