Investigating the roles of candidate gap genes from the neuroblast timer series during axial patterning in the beetle Tribolium
The gap genes encode transcription factors that play a central role in the process of segment patterning in Drosophila. Specifically, they interact to form the well-characterised ‘gap gene network’, which directs the formation of segment boundaries (through regulation of pair-rule genes), and the …

KEY DEVELOPMENTAL EVENTS IN THE ORIBATID MITE, ARCHEGOZETES LONGISETOSUS, AND THE EVOLUTION OF CHELICERATE BODY PLANS.
… shown that a conserved suite of developmental genes pattern the chelicerate body plan, with slight modifications in their expression patterns correlating with morphological diversification and evolution of segments and the appendages that they bear. Although a few tractable evo devo chelicerate …

Analysis of Tribolium head patterning by forward and reverse genetics and transgenic techniques
In dieser Doktorarbeit wurden verschiedene Methoden angewandt um ein besseres Verständnis der Insektenkopfentwicklung zu erlangen. Als Modellorganismus wurde der Rotbraune Reismehlkäfer Tribolium castaneum ausgewählt. Dieser Organismus ist für die Analyse dieses Prozesses gut geeignet, da Larven …

Computational modeling of gene expression from regulatory sequences
… patterns of anterior-posterior patterning genes in the early Drosophila embryo. Altogether, we model the expression patterns of 27 genes; these include several gap genes, pair-rule genes, and anterior, posterior, trunk, and terminal genes. We find that the model-selected enhancers for each …
