Gender- and stressor-specific microRNA expression in Tribolium castaneum

Gender- and stressor-specific microRNA expression in Tribolium castaneum

MicroRNAs (miRNAs) are small non-coding RNAs mediating post-transcriptional regulation of gene expression in eukaryotes. Addressing their role in regulation of physiological adaptations to environmental stress in insects, we selected the red flour beetle Tribolium castaneum as a model. Beetles were fed with the bacterial entomopathogen Pseudomonas entomophila (to mimic natural infection), injec...

Embryonic patterning mutants of Tribolium castaneum.

The identification and analysis of genes controlling segmentation in Drosophila melanogaster has opened the way for understanding similarities and differences in mechanisms of segmentation among the insects. Homologues of Drosophila segmentation genes have been cloned and their expression patterns have been analyzed in a variety of insects, revealing that the patterns of expression of many gene...

Expanding the genetic toolkit of Tribolium castaneum

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

As invertebrates lack the molecular machinery employed by the vertebrate adaptive immune system, it was thought that they consequently lack the ability to produce lasting and specific immunity. However, in recent years, it has been demonstrated that the immune defence of invertebrates is by far more complicated and specific than previously envisioned. Lasting immunity following an initial expos...

Close linkage of eye color genes in Tribolium castaneum.

N the course of linkage studies involving several new mutations affecting eye I pigmentation in the flour beetle, Tribolium castaneum, it became apparent that while being nonallelic to each other and to previously reported eye mutants they were not randomly distributed in the genome. In fact, of the nine eye mutant loci thus far reported, six occur as colsely linked members of three gene pairs....
