INVESTIGATING PAIR-RULE GENE ORTHOLOGS IN AN INTERMEDIATE GERM BEETLE, DERMESTES MACULATUS
… in which segments are established by a genetic hierarchy including gap, pair-rule and segment polarity genes. Pair-rule genes (PRGs) are a key class of segmentation genes as they are the first cohort of genes expressed in a periodic pattern. Segments are established simultaneously in …

Clock-based segmentation in the red flour beetle Tribolium castaneum
… Specifically, I show that the Tribolium primary pair-rule gene, Tc-even-skipped (Tc-eve), is expressed in waves propagating from the posterior pole and progressively slowing until they freeze into stripes; such dynamics are a hallmark of clock-based segmentation. Phase shifts between Tc-eve …

Investigating the cell surface code for compartment boundary formation in Drosophila embryos
… only begun to be identified. Further, there is generally a poor understanding of how cell identity information is read to promote actomyosin enrichments. Beyond cell segregation, the role of mechanical boundaries during tissue morphogenesis is unclear. In this thesis, I studied the compartmental …

Odd-paired: a zinc finger pair-rule protein required for the timely activation of engrailed and wingless in Drosophila embryos
<p>Here I report a molecular and genetic analysis of the pair-rule gene odd-paired (opa). Genetically, opa is essential for the appropriate level and timing of en and wg expression in all parasegments, but opa activity alone does not determine the restricted spatial domains of these genes. I …
