A team of researchers from the University of southern Mississippi
and the university of Michigan, suggest that the dust mite, might have developed a new
way to protect its genome from internal disruptions. They sequenced the DNA and the RNA of the American house dust
mite, Dermatophagoides farina and looked at the populations of small RNA
molecules encoded there.
They found that the
dust mites do not have the Piwi proteins or associated RNAs that most animals
have that control transposable elements. The mites have been characterized with
having dramatic genetic transitions based on their transition to parasitism.
