Third-party-funded project

Hormonal control of the silk genes in the graeter wax moth, Galleria mellonella.

Project management at the University of Würzburg:

Participating scientists:

The silk glands of Galleria mellonella provide a highly suitable system for the investigation of differential gene expression because they show clearly cut developmental stages like proliferation, differentiation and apoptosis. These stages are correlated with the expression of silk protein genes. Silk is a complex mixture of different proteins of which sericins and fibroins are the most important ones. We have been sucessful in cloning the cDNA and genes for 4 silk components. We could demonstrate that the corresponding mRNAs are differentially spliced under the control of juvenile hormone
