Hierarchy and CIS-Regulation in Drosophila Segmentation: Rules for Pattern Formation and Clues to Evolution
… the transcriptional regulatory regions of genes of the gap and pair rule classes such an analysis is carried out. Computational analysis, transgenic reporter element assays, site directed mutagenesis, genetics, and time courses of in situ hybridizations of central genes in carefully staged …

INVESTIGATING PAIR-RULE GENE ORTHOLOGS IN AN INTERMEDIATE GERM BEETLE, DERMESTES MACULATUS
… 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 Drosophila in early embryos, while …

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 …

A Genetic Test of a Model for Two Activities of Fushi Tarazu Protein in Drosophila Melanogaster
The important pair-rule segmentation gene fushi tarazu (ftz) encodes a homeodomain (HD)-containing protein involved in the establishment of even-numbered parasegments during embryonic development. The D. melanogaster ftz is a derived homeotic selector (Hox) gene which lost its homeotic function …

Developmental dynamics of posterior segment addition in the spider Parasteatoda tepidariorum
… along the anterior–posterior axis during embryogenesis. It is thought that this modularity facilitated diversification of the body plan, making segmentation an evolutionarily advantageous trait. Arthropods exhibit diverse segmentation modes, ranging from the near-simultaneous formation of …

Computational modeling of gene expression from regulatory sequences
… control over biological processes. The rules, collectively known as the “cis-regulatory logic”, to predict gene expression level given information about CRMs and TFs, however, are unclear. Decades of experimental studies have hypothesized mechanisms about parts of this regulatory process …
