TBG project summary

Caddisfly silk is a unique material that combines great tensile strength, elasticity, and the ability to form underwater. These characteristics make caddisfly silk an interesting material for potential application, e.g. in surgery. Caddisflies use silk in many different ways, e.g. as underwater life lines, to build filtering nets or living retreats, and even to “glue together” mineral or organic particles to build the portable cases caddisflies are known for. In our TBG project we aim to study the genomic basis of different uses and characteristics of caddisfly silk and how these evolved. We aim to accomplish this by comparing the sections of the genome that are responsible for silk production among closely related species of caddisflies that use silk in different ways, e.g. those that build cases made purely of silk with those that build cases with mineral particles.
