Doublesex 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 کاملLarval 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 کامل15-P041 Early Neurogenesis in the red flour beetle Tribolium castaneum
Retinoids are vital for normal embryonic development and are necessary during postnatal development and adulthood for the maintenance of the reproductive and nervous system and for visual pigment synthesis. STRA6 (Stimulated by retinoic acid 6) is the cell surface receptor for retinol binding protein (RBP4), which facilitates the cellular uptake of retinol. Mutations in Stra6 are responsible fo...
متن کاملThe Roles of the Wnt-Antagonists Axin and Lrp4 during Embryogenesis of the Red Flour Beetle Tribolium castaneum
In both vertebrates and invertebrates, the Wnt-signaling pathway is essential for numerous processes in embryogenesis and during adult life. Wnt activity is fine-tuned at various levels by the interplay of a number of Wnt-agonists (Wnt ligands, Frizzled-receptors, Lrp5/6 coreceptors) and Wnt-antagonists (among them Axin, Secreted frizzled and Lrp4) to define anterior-posterior polarity of the e...
متن کاملAFLP-based genetic linkage map for the red flour beetle (Tribolium castaneum).
The red flour beetle (Tribolium castaneum) is a major pest of stored grain and grain products and a popular model species for a variety of ecological, evolutionary, and developmental biology studies. Development of a linkage map based on reproducible and highly polymorphic molecular markers would greatly facilitate research in these disciplines. We have developed a genetic linkage map using 269...
