According to the most recent taxonomic literature, three species of the genus Eresus are known in Central Europe, Eresuskollari, Eresussandaliatus and Eresusmoravicus. We recognized a fourth distinctive species from Hungary, which is... more
Although the boundary elements of the Drosophila Bithorax complex (BX-C) have properties similar to chromatin insulators, genetic substitution experiments have demonstrated that these elements do more than simply insulate adjacent... more
The Abd-B gene, one of the three homeotic genes in the Drosophila bithorax complex (BX-C), is required for the proper identity of the fifth through the eighth abdominal segments (corresponding to parasegments 10-14) of the fruitfly. The... more
Eukaryotic chromosomes are thought to be organized into a series of discrete higher-order chromatin domains. This organization is believed to be important not only in the compaction of the chromatin fibre, but also in the utilization of... more
Ethyl methanesulphonate (EMS) was used to induce 39 lethal and 13 karmoisin mutations within Df(3R)kar(3J), a nine-band deficiency extending from 87C1 to 87C9 (inclusive). Five complementation groups (four lethal and one visible) were... more
The three homeotic genes of the bithorax complex (BX-C), Ubx, abd-A and Abd-B control the identity of the posterior thorax and all abdominal segments. Large segment-specific cis-regulatory regions control the expression of Ubx, abd-A or... more
The RpII215 region of the X chromosome of Drosophila melanogaster was investigated to identify genetic functions and correlate these with the known molecular organization of the region. Five genetic loci were identified in a subregion... more
