Larval RNA Interference in the Red Flour Beetle, Tribolium castaneum
The red flour beetle, Tribolium castaneum, offers a repertoire of experimental tools for genetic and developmental studies, including a fully annotated genome sequence, transposon-based transgenesis, and effective RNA interference (RNAi). Among these advantages, RNAi-based gene knockdown techniques are at the core of Tribolium research. T. castaneum show a robust systemic RNAi response, making ...
متن کاملDoublesex target genes in the red flour beetle, Tribolium castaneum
Sex determination cascade in insects terminates with the production of sex-specific protein, Doublesex (Dsx). We identified the dsx homolog (Tcdsx) in Tribolium castaneum. The pre-mRNA of Tcdsx is sex-specifically spliced into three female (Tcdsxf1, Tcdsxf2 and Tcdsxf3) and one male-specific (Tcdsxm) isoforms. Cis-regulatory elements potentially involved in sex-specific splicing of the Tcdsx pr...
متن کاملTrOn: An Anatomical Ontology for the Beetle Tribolium castaneum
In a morphological ontology the expert's knowledge is represented in terms, which describe morphological structures and how these structures relate to each other. With the assistance of ontologies this expert knowledge is made processable by machines, through a formal and standardized representation of terms and their relations to each other. The red flour beetle Tribolium castaneum, a represen...
متن کاملSatellite DNA as a Driver of Population Divergence in the Red Flour Beetle Tribolium castaneum
Tandemly repeated satellite DNAs are among most rapidly evolving sequences in eukaryotic genome, usually differing significantly among closely related species. By inducing changes in heterochromatin and/or centromere, satellite DNAs are expected to drive population and species divergence. However, despite high evolutionary dynamics, divergence of satellite DNA profiles at the level of natural p...
متن کاملRegular Higher Order Repeat Structures in Beetle Tribolium castaneum Genome
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...
