Serial homologs are similar structures that develop at different positions within a body plan. These structures share some, but not all, aspects of developmental patterning, and their evolution is thought to be constrained by shared, pleiotropic gene functions. Here we describe the functions of 17 developmental genes during metamorphic development of the legs in the red flour beetle, Tribolium ...
Higher order repeats (HORs) containing tandems of primary and secondary repeat units (head-to-tail "tandem within tandem pattern"), referred to as regular HORs, are typical for primate alpha satellite DNAs and most pronounced in human genome. Regular HORs are known to be a result of recent evolutionary processes. In non-primate genomes mostly so called complex HORs have been found, without head...
Late-instar larvae, pupae, and adults of Tribolium castaneum (Herbst), the red flour beetle, or Tribolium confusum (DuVal), the confused flour beetle, were exposed for variable durations at 36–54 1C. Beetles were placed in laboratory ovens set at a baseline of 27 1C, the temperature was increased by 0.1 1C per minute until the target temperature was achieved, and beetles were then held for spec...
To test the efficacy of RNA interference (RNAi) as a method for target-site screening in Diabrotica virgifera virgifera LeConte (Coleptera: Chrysomelidae) larvae, genes were identified and tested for which clear RNAi phenotypes had been identified in the Coleopteran model, Tribolium castaneum. Here the cloning of the D. v. vergifera orthologs of laccase 2 (DvvLac2) and chitin synthase 2 (DvvCHS...
Insect metamorphosis is regulated by ecdysteroids, which induce molts, and juvenile hormone (JH), which inhibits metamorphic changes. The molecular action of ecdysteroids has been thoroughly studied, but that of JH is poorly understood, with data currently only being available for holometabolous species, like Drosophila melanogaster and Tribolium castaneum. We studied the function of Krüppel ho...
Gene-editing techniques are revolutionizing the way we conduct genetics in many organisms. The CRISPR/Cas nuclease has emerged as a highly versatile, efficient and affordable tool for targeting chosen sites in the genome. Beyond its applications in established model organisms, CRISPR technology provides a platform for genetic intervention in a wide range of species, limited only by our ability ...
