Inside the Tangled Bank of Arthropods

 

We unravel the molecular-genetic mechanisms of hybrid dysfunction, herbivory, and pesticide resistance. One of the major research lines dissects the mechanistic underpinnings of symbiont-host interactions. We use interdisciplinary approaches to study the molecular architecture of these complex traits.

 

 

 

>>> Our study of the underlying mechanisms and relevance of Wolbachia-induced sex allocation distortion (Sd) in haplodiploids has been published this summer in Heredity! GO TO ARTICLE! Sd is an often neglected symbiont-mediated reproductive phenotype in haplodiploids. We show that Wolbachia-mediated Sd is driven by increasing egg provisioning, facilitating egg fertilization and subsequent female development. This physiological effect is contingent on the female host genotype and can cause larger adult offspring. Our simulations show that Sd is able to remove the threshold for Wolbachia invasion under certain realistic conditions.
