Sperm size and number variation in the red flour beetle

Strain-specific priming of resistance in the red flour beetle,

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...

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 ...

Rationale to sequence the genome of the red flour beetle,

Overview: In a world of worthy candidates, there are several compelling reasons to sequence the genome of the red flour beetle Tribolium castaneum. First and foremost, Tribolium is one of the most sophisticated genetic model organisms among all higher eukaryotes. Among arthropods, only Drosophila offers greater power and flexibility of genetic manipulation. Second, the Tribolium genome sequence...
