Irina Arkhipova said : "This is very unusual and has not been previously reported," "Horizontally transferred genes are thought to preferentially be operational genes, not regulatory genes. It is hard to imagine how a single, horizontally transferred gene would form a new regulatory system, because the existing regulatory systems are already very complicated" External link

Irina Arkhipova said : "Bdelloid rotifers, especially, have to keep their transposons in check because they primarily reproduce asexually," "Asexual lineages have fewer means for suppressing proliferation of deleterious transposons, so adding an extra layer of protection could prevent a mutational meltdown. Indeed, transposon content is much lower in bdelloids than it is in sexual eukaryotes that don't have this extra epigenetic layer in their genome defense system" External link

Irina Arkhipova said : "When they rehydrate or otherwise render their DNA ends accessible, this might be an opportunity for foreign DNA fragments from ingested bacteria, fungi, or microalgae to transfer into the rotifer genome," External link

Irina Arkhipova said : "We hypothesized that this gene conferred this new function of suppressing transposons, and we spent the last six years proving that, indeed, it does," External link
