The role of Ultrabithorax negative autoregulation in Drosophila melanogaster
… Focusing on the D. melanogaster Hox gene Ultrabithorax (Ubx), I explore how cis-regulatory elements of developmental control genes contribute to these two hallmarks of developmental biology: versatility and robustness. Ubx specifies the identity of the third thoracic (T3) segment along the …

Investigation of Interactions between Homeodomain Proteins and DNA
… und des Circulardichroismus von Bicoid- (Bcd), Ultrabithorax- (Ubx) und Engrailed- (En) Homeodomänen hat gezeigt, dass die Bindung dieser Proteine an doppelsträngige 15 bp Oligonukleotide Veränderungen in der Sruktur der Homeodomänen hervorruft. Diese Veränderungen sind unterschiedlich für …

KEY DEVELOPMENTAL EVENTS IN THE ORIBATID MITE, ARCHEGOZETES LONGISETOSUS, AND THE EVOLUTION OF CHELICERATE BODY PLANS.
… and that the mite homologues of the Hox genes Ultrabithorax and Abdominal-B are only expressed in a single segment in the opisthosoma in A. longisetosus. These findings are placed within a comparative framework to aid in the understanding of the evolution of arthropod and chelicerate body plans.

Identifizierung und Charakterisierung von Histonmethyltransferasen in Drosophila melanogaster
… epigenetischen ASH1-abhängigen Aktivierung der Ultrabithorax-Transkription in Drosophila mit ASH1-vermittelter Histonmethylierung und Rekrutierung oder Stabilisierung der Bindung des aktivierenden Chromatin-Remodelling-Komplexes BRAHMA, dem Dro-sophila SWI/SNF-Homolog, nachgewiesen werden. Die …

Investigating the roles of candidate gap genes from the neuroblast timer series during axial patterning in the beetle Tribolium
… the abdominal Hox genes Tc-abdominal A and Tc- Ultrabithorax. These data indicate that Tc-nub, Tc-gt and Tc-kni act redundantly to repress the expression of Tc-Kr in the abdomen, and that both Tc-nub and Tc-kni should therefore be considered as components of the gap gene network in Tribolium. My …

Unraveling The Genetic Mechanisms Involved In The Evolution And Development Of The Thoracic Appendages In Insects
… from our lab has shown that the homeotic gene Ultrabithorax (Ubx) plays a key role in the enlargement of hind legs not only in orthopterans, but other insect species as well. Another example of a greatly modified hind leg is seen in the honeybee, Apis mellifera, which has been adapted for the …

The Cellular And Genetic Mechanisms Underlying Morphological Diversity Of Insects
… legs in <i>Acheta</i>, the homeotic gene <i>Ultrabithorax (Ubx)</i> is responsible for allometric differences in size between the mid and hind legs. While the embryonic role of <i>Ubx</i> has been well documented, virtually nothing is known about its post-embryonic function in hemimetabolous …
